Skin and Nasal Involvement: Look for Sarcoidosis!
Sarcoidosis is a systemic, noncaseating, granulomatous disease affecting young adults between the ages of 25 and 40 years, most often of Black origin (35.5/100,000 vs 10.9 in the White population). Although the lower respiratory tract is affected in 90% of cases, ear, nose, and throat locations are very uncommon, with a prevalence varying between 1% and 6.5%.1 In addition, ear, nose, and throat manifestations are nonspecific, and may be difficult to differentiate from other granulomatous diseases such as actinomycosis, aspergillosis, antineutrophil cytoplasmic antibody-associated vasculitis and tuberculosis, thus, frequent...

Nuclear Imaging in Sarcoidosis
Sarcoidosis is a multisystem granulomatosis which may result in a wide variety of clinical and biological presentations. Symptoms are often nonspecific, and incidental abnormal findings on chest radiography is rather common. Although sarcoidosis resolves favorably in most cases, some localizations can provoke functional impairment or even impact on patients' prognosis. The diagnosis is based on a pathological hallmark which is the non-necrotizing epithelioid-cell rich granuloma.Owing to the ability to detect inflammation throughout the body with a high sensibility, FDG-PET/CT gained a central role in sarcoidosis because it...

Sarcoidosis presenting as Wallenberg syndrome and panuveitis
We report a case of a patient who presented with the lateral medullary syndrome and panuveitis as her initial manifestation of sarcoidosis. The patient's course was further complicated by renal involvement. Lacrimal gland and renal biopsies showed noncaseating granulomas without evidence of infection, establishing the diagnosis. Intracranial vertebral artery involvement was confirmed by brain imaging. Bilateral hilar lymphadenopathy with upper lobe predominant nodules on chest imaging was consistent with asymptomatic pulmonary involvement. Systemic steroid therapy is indicated for treatment of ocular sarcoidosis, with stan...

Sarcoidosis-associated Pulmonary Hypertension: Pathophysiology, Diagnosis, and Treatment
Clinicians in pulmonary medicine frequently confront the challenge of screening, diagnosis, and management of pulmonary hypertension (PH) in sarcoidosis patients who present with unexplained dyspnea. Sarcoidosis-associated pulmonary hypertension (SAPH) is most prevalent in patients with pulmonary fibrosis, although it can be independent of airflow obstruction or restriction. SAPH is independently associated with significantly increased mortality and decreased functional capacity, outcomes that can be mitigated by early detection and focused treatment. In this review, we discuss the pathophysiology of SAPH, which may resemb...

Increased T-helper 17.1 cells in sarcoidosis mediastinal lymph nodes
In this study, we aimed to investigate 1) whether Th17.1 cells are also increased in the MLNs of sarcoidosis patients and 2) whether frequencies of the Th17.1 cells at diagnosis may correlate with disease progression. MLN cells from treatment-naive pulmonary sarcoidosis patients (n=17) and healthy controls (n=22) and peripheral blood mononuclear cells (n=34) and bronchoalveolar lavage fluid (BALF) (n=36) from sarcoidosis patients were examined for CD4+ T-cell subset proportions using flow cytometry. Higher proportions of Th17.1 cells were detected in sarcoidosis MLNs than in control MLNs. Higher Th17.1 cell proportions wer...

Reassessing Th1 versus Th17.1 in sarcoidosis: new tricks for old dogma
Immunologically, sarcoidosis has been classically defined by the presence of a Th1-dominant environment localised to sites of disease, characterised by overexpression of interferon (IFN) and Th1-promoting interleukin (IL)12 and IL18 . Accordingly, the downstream effects of enhanced Th1 are also observed in sarcoidosis, such as the expression of Th1-associated chemokines (MIG/CXCL9, IP10/CXCL10, ITAC/CXCL11, MCP1/CCL2, MIP1α/CCL3, MIP1β/CCL4, RANTES/CCL5) and their respective receptors (CXCR3, CCR5). Conversely, the presence of augmented Th2 has never been firmly documented in the sarcoidosis lung.

Pancreatitis as the presenting symptom of abdominal sarcoidosis.
We present a 60-year-old woman with non-pulmonary sarcoidosis manifesting as acute pancreatitis, possibly due to hypercalcaemia. Pancreatitis in sarcoidosis is rare, particularly as a presenting symptom. This case demonstrates that sarcoidosis should be included in the differential diagnosis of pancreatitis with hypercalcaemia, even without pulmonary signs of sarcoidosis.

Cryptococcal-related meningoencephalitis in a patient with sarcoidosis and CD4 lymphocytopenia: thorough immunological characterization of lymphocyte homeostasis.
We report on reduced production of new T cells observed in a patient with sarcoidosis, CD4 lymphocytopenia, and cryptococcal-related meningoencephalitis. Although T cells presented with an intact proliferative capacity, they were oligoclonally expanded showing an effector memory phenotype. However, the deleterious activity of effector memory cells could have been controlled by the expansion of the regulatory T cell subset with the highest suppressive capability. This information provide a better understanding of the immune response to cryptococcus occurring in non-HIV-associated cases, the predisposition to infection, and ...

The Clinical Features of Sarcoidosis: A Comprehensive Review
Abstract Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in mos...

A cytomorphometric analysis of pulmonary and mediastinal granulomas: Differentiating histoplasmosis from sarcoidosis by fine‐needle aspiration
CONCLUSIONSDifferentiation between histoplasmosis and sarcoidosis is possible in the majority of cases. Histoplasmosis usually exhibits few angular, ragged granulomas (<2 granulomas per slide) in a background of bland necrosis. Yeasts are identified on special stains performed in aspirate smears. Sarcoidosis typically contains many more granulomas (often >10 per slide) than histoplasmosis and has a rounded morphology with crisp and sharp borders. Typically, there is no necrosis or acute inflammation, and giant cell infiltrates are frequent. Cancer (Cancer Cytopathol) 2014. © 2014 American Cancer Society.

Longitudinal analysis of sarcoidosis blood transcriptomic signatures and disease outcomes
Previously, we demonstrated concordance in differentially expressed genes in sarcoidosis blood and lung, implicating shared dysfunction of specific immune pathways. In the present study, we hypothesised that expression levels of candidate genes in sarcoidosis blood could predict and track with disease outcomes longitudinally. We applied Ingenuity Pathway Analysis to a cross-sectional derivation microarray dataset (n=38) to identify canonical pathways and candidate genes associated with sarcoidosis. In a separate longitudinal sarcoidosis cohort (n=103), we serially measured 48 candidate gene transcripts, and assessed their ...

Esophageal cancer associated with bilateral hilar lymphadenopathy caused by sarcoid-like reactions: a report of two cases
We report two patients with esophageal cancer accompanied by bilateral hilar lymphadenopathy or accumulation on [18F]-fluorodeoxyglucose positron emission tomography–computed tomography. The first patient underwent surgery because the enlarged bilateral hilar lymph nodes were considered to be nonmalignant lesions owing to superficial carcinoma and symmetric distribution of the hilar lymph nodes. The second patient received chemotherapy, which caused the main tumor to shrink and decreased [18F]-fluorodeoxyglucose uptake. However, chemotherapy did not affect the hilar lymphadenopathy, which suggests that it was caused by r...

Application of medical thoracoscopy in diagnosis of sarcoidosis‐related pleural effusion
Abstract Pleural effusion caused by sarcoidosis is unusual. Medical thoracoscopy could help clinicians detect associated pleural disease, yet studies on thoracoscopic observations in sarcoidosis pleural involvement are rare. In this article, we report the utility of medical thoracoscopy in diagnosing sarcoid‐related pleural disease for three patients. Pleural nodularity was common with solitary and multiple nodules evident; biopsies confirmed the presence of diagnostic noncaseating granulomas. Medical thoracoscopy showed that sarcoidosis pleural involvement was variable from multiple nodules to subtle change in the pleura.

Sixth nerve palsy associated with obstruction in Dorello's canal, accompanied by nodular type muscular sarcoidosis
Abstract: A 52-year-old Japanese woman complaining of horizontal double vision for 10days was admitted to our hospital. Neurological examination revealed left abducent nerve palsy and muscle swelling in her thighs. Brain MRI showed obstruction in the spinal fluid space of the left Dorello's canal, which transmits a portion of the abducent nerve. In Ga-67-enhanced citrate scintigraphy, wide accumulation was seen in her bilateral thighs, lower legs, and gluteus muscles. Muscular MRI showed a star-shaped central structure on short tau inversion recovery (STIR) images, and the three stripes sign on T2-weighted images. These MR...

Cardiac sarcoidosis presenting as constrictive pericarditis.
We report the case of a 57-year-old man who presented with clinical and hemodynamic features of constrictive pericarditis, of unclear cause. He was admitted for treatment of recurrent pleural effusion. After a complicated hospital course, he underwent pericardiectomy. His clinical and hemodynamic conditions improved substantially, and he was discharged from the hospital in good condition. The pathologic findings, the patient's clinical course, and his response to pericardiectomy led to our diagnosis of cardiac sarcoidosis presenting as constrictive pericarditis. In addition to the patient's case, we discuss the nature and ...

Gene expression profiles in granuloma tissue reveal novel diagnostic markers in sarcoidosis.
Abstract Sarcoidosis is an immune-mediated multisystem disease characterized by the formation of non-caseating granulomas. The pathogenesis of sarcoidosis is unclear, with proposed infectious or environmental antigens triggering an aberrant immune response in susceptible hosts. Multiple pro-inflammatory signaling pathways have been implicated in mediating macrophage activation and granuloma formation in sarcoidosis, including IFN-γ/STAT-1, IL-6/STAT-3, and NF-κB. It is difficult to distinguish sarcoidosis from other granulomatous diseases or assess disease severity and treatment response with histopathology alon...

Foreign Body Granulomatous Reaction to Silica, Silicone, and Hyaluronic Acid in a Patient With Interferon-Induced Sarcoidosis.
We report the case of a patient who developed sarcoid granulomas 11 months after starting treatment with pegylated interferon alfa and ribavirin for chronic hepatitis C. The sites of the lesions were related to 3 different foreign bodies: silica in old scars on the skin, hyaluronic acid that had been injected into facial tissues, and silicone in an axillary lymph node draining the area of a breast implant. Systemic sarcoidosis was diagnosed on the basis of a history of dry cough and fever and blood tests that revealed elevated angiotensin converting enzyme and liver enzymes.

ICAM-1 Deficiency Exacerbates Sarcoid-Like Granulomatosis Induced by Propionibacterium acnes through Impaired IL-10 Production by Regulatory T Cells.
Abstract Propionibacterium acnes has been implicated as one of the suggested causative antigens for sarcoidosis, a systemic granulomatous disease. By injecting heat-killed P. acnes into the dorsal skin of C57BL/6J mice on days 1, 3, 5, and 14, sarcoid-like granulomatosis was induced in skin and lungs of these mice on day 28. To clarify the role of cell adhesion molecules in cutaneous sarcoidosis, we induced sarcoid-like granulomatosis in mice deficient of intercellular adhesion molecule (ICAM)-1, L-selectin, P-selectin, or E-selectin via repeated P. acnes injection. Histopathologic analysis revealed that granuloma...

Atypical radiological manifestations of thoracic sarcoidosis: A review and pictorial essay
We present a review of literature and illustrate the review with unpublished data, intended to provide a more recent single comprehensive reference to assist with the diagnosis when atypical radiographic findings of thoracic sarcoidosis are encountered. Thoracic involvement accounts for most of morbidity and mortality associated with sarcoidosis. An accurate timely identification is required to minimize morbidity and mortality. It is essential to recognize atypical imaging findings and relate these to clinical manifestations and histology.

Microbial and human heat shock proteins as 'danger signals' in sarcoidosis.
Abstract In the light of the Matzinger's model of immune response, human heat shock proteins (HSPs) as main 'danger signals' (tissue damage-associated molecular patterns-DAMPs) or/and microbial HSPs as pathogen-associated molecular patterns (PAMPs) recognized by pattern recognition receptors (PRR), may induce sarcoid granuloma by both infectious and non-infectious factors in genetically different predisposed host. Regarding infectious causes of sarcoid models, low-virulence strains of, e.g. mycobacteria and propionibacteria recognized through changed PRR and persisting in altered host phagocytes, generate increase...

Acute kidney injury in a patient with sarcoidosis: hypercalciuria and hypercalcemia leading to calcium phosphate deposition.
We present a patient with sarcoidosis who developed acute kidney injury (AKI). He had a high 1,25-OH vitamin D level and hypercalciuria. As his renal function declined he developed hypercalcemia. A kidney biopsy showed acute tubular necrosis (ATN) with giant cell formation around calcium phosphate crystals. Calcium phosphate deposition is uncommon in sarcoid. We speculate that early interstitial calcium phosphate deposition may in time lead to the development of Randall's plaques and to the more typical calcium oxalate nephrolithiasis seen in sarcoidosis.

Etiologic Aspect of Sarcoidosis as an Allergic Endogenous Infection Caused by Propionibacterium acnes.
Abstract Sarcoidosis is a systemic granulomatous disease of unknown etiology. Propionibacterium acnes is the only microorganism that has been isolated from sarcoid lesions. Many P. acnes have been detected in sarcoid lymph nodes using quantitative PCR and in sarcoid granulomas by in situ hybridization. P. acnes trigger factor protein causes a cellular immune response only in sarcoid patients and induces pulmonary granulomas in mice sensitized with the protein and adjuvant, but only those with latent P. acnes infection in their lungs. Eradication of P. acnes by antibiotics prevents the development of granulomas in ...

Heart Transplantation for End-Stage Heart Failure Due to Cardiac Sarcoidosis
Conclusions: Patients with cardiac sarcoidosis undergoing heart transplantation have acceptable long-term outcomes without evidence of recurrence of sarcoidosis in the allograft when maintained on low-dose corticosteroids. Progression of extracardiac sarcoid was uncommon, possibly related to immunosuppression. In patients with cardiac sarcoidosis, heart transplantation is a viable treatment modality.

Abstract Sarcoidosis is a multisystem granulomatous disease of unknown cause that commonly involves the spleen. Sarcoid can produce either homogeneous splenomegaly or multiple splenic nodules. Although other organ system involvement usually occurs, this is not invariable. Herein, we report on the clinical, histological, and radiological features—including sonography and MRI—of an isolated splenic sarcoidosis that mimicked neoplastic disease in a 37‐year‐old female. Knowledge of this atypical sonographic presentation may prevent unnecessary splenectomy. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound, 2013

Sarcoid-like granulomatosis induced by Propionibacterium acnes in mice; role of ICAM-1 in prevention of granuloma formation
Sarcoidosis is a systemic granulomatous disease which is characterized by a variable clinical presentation and course. The etiology of the disease has remained unknown. Propionibacterium acnes (P. acnes), an anaerobic nonspore-forming gram-positive rod bacterium, has been implicated as one of the suggested causative antigens of sarcoidosis since this bacterium has been isolated from sarcoid lesions. In order to clarify the role of cell adhesion molecules in cutaneous sarcoidosis, we first established an in vivo model of sarcoid-like skin granulomatosis by injecting heat-killed P. acnes into the back of C57BL/6J mice. These...
