Gallium-68 DOTA-NOC PET/CT as an alternate predictor of disease activity in sarcoidosis
Introduction We evaluated the role of gallium-68-labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-Nal3-octreotide (68Ga-DOTA-NOC) PET/CT in assessing sarcoidosis disease activity. Patients and methods Patients diagnosed with sarcoidosis underwent 68Ga-DOTA-NOC-PET/CT. The maximum standardized uptake value (SUVmax) at the pathological site and in the descending thoracic aorta (reference standard, SUVmed) were assessed. A SUVmax/SUVmed ratio (disease activity score) of more than one was considered a marker of active disease and was compared with the clinical symptoms and serum angiotensin-converting ...

The fear of lymphadenopathy: A cautionary case of sarcoidosis masquerading as recurrent diffuse large b-cell lymphoma (DLBCL)
We describe the cautionary case of a patient with advanced-stage large B-cell lymphoma (DLBCL). After combination chemotherapy, CT-PET revealed a persistent focus of likely DLBCL for which he received radiotherapy. Follow-up CT-PET showed diffuse hypermetabolic adenopathy and recurrent DLBCL was presumed. As part of clinical trial assessment, multiple biopsies showed non-caseating lymphadenitis consistent with sarcoidosis. No treatment for asymptomatic sarcoidosis was required and 18 months later he remains cancer-free. The presentation of sarcoidosis masquerading as recurrent DLBCL highlights the importance of tissue samp...

Coexistence of sarcoidosis and Hashimoto thyroiditis.
Abstract Sarcoidosis is a chronic, inflammatory disease with unknown cause characterized by non-caseating granuloma formations. It can present with bilateral hilar lymphadenopathy, skin lesions, eye involvement and locomotor system findings. Hashimoto thyroiditis is an organ-specific autoimmune disease characterized by increased autoantibody synthesis. Sarcoidosis can involve different endocrine glands. Thyroid gland involvement may lead to increased thyroid function disorders and autoantibodies. Herein, we report an 80-year-old female patient with sarcoidosis and Hashimoto coexistence.

Safety and efficacy of ustekinumab or golimumab in patients with chronic sarcoidosis
Sarcoidosis is characterised by non-caseating granulomas that secrete pro-inflammatory cytokines, including interleukin (IL)-12, IL-23, and tumour necrosis factor (TNF)-α. Ustekinumab and golimumab are monoclonal antibodies that specifically inhibit IL-12/IL-23 and TNF-α, respectively. Patients with chronic pulmonary sarcoidosis (lung group) and/or skin sarcoidosis (skin group) received either 180 mg ustekinumab at week 0 followed by 90 mg every 8 weeks, 200 mg golimumab at week 0 followed by 100 mg every 4 weeks, or placebo. Patients underwent corticosteroid tapering between weeks 16 and 28. The primary end-po...

Clinical features of sarcoid myelopathy focusing on age, distribution, and concomitant spinal disease
Background: Myelopathy is a relatively rare manifestation of sarcoidosis. Although spinal cord compression related to spinal cord swelling was reported in sarcoid myelopathy, the relationship between sarcoid myelopathy and mechanical compression due to orthopedic disorders has not been fully evaluated. We aimed to reveal clinical and radiological features of sarcoid myelopathy that demarcate the disease from other inflammatory myelopathy (OIM), especially focusing on age, distribution of spinal cord lesion (SCL), and concomitant orthopedical spinal diseases.

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...

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.

Sarcoidosis Manifesting as a Pseudotumorous Renal Mass
A 53 year-old African American woman with a three-year history of pulmonary sarcoidosis had a follow-up computed tomographic scan to evaluate the status of her disease and response to treatment. On the scan, an abnormal, hypodense mass on the left renal superior pole, which was not present on previous scans, was incidentally discovered. The initial concern was of carcinoma, despite her lack of any urinary symptoms. She underwent further evaluation with magnetic resonance, and the enhancement pattern and the shape of the mass were more suggestive of lymphoma or infarction than a carcinoma.

Discussion: In patients with clinical lacrimal gland enlargement, incisional biopsy led to a diagnosis of sarcoidosis in 20% of patients. An elevated ACE level may help predict which patients have a greater diagnostic yield with biopsy. PMID: 23480843 [PubMed - in process]

Coexistence of sarcoidosis with seminoma - a case report.
Abstract A 30-year-old patient, with diagnosis of seminoma (T1 Nx Mx) was treated radically with orchidectomy. In chest CT performed postoperatively numerous diffuse nodules were revealed in both lungs. Lesions were situated particularly in the upper and middle pulmonary zones. In order to verify the nature of pulmonary abnormalities videothoracoscopy of the right pleural cavity was performed with specimen collection. Histopathological examination excluded the possibility of cancer metastases to pulmonary parenchyma and revealed the presence of sarcoid-like granulomas. Coexistence of seminoma and diffuse sarcoid-l...

Preliminary characterizations of a serum biomarker for sarcoidosis by comparative proteomic approach with tandem-mass spectrometry in ethnic Han Chinese patients
Background: The diagnosis of sarcoidosis is still a significant challenge in China because of the need to exclude other diseases including granulomatous infections and malignancies that may be clinically and radiographically similar. The specific aim of the study is to search for serum protein biomarkers of sarcoidosis and to validate their clinical usefulness in differential diagnosis. Methods: Serum samples were collected from patients with sarcoidosis (n = 37), and compared to those from patients with tuberculosis (n = 20), other pulmonary diseases (n = 20), and healthy volunteers (n = 20) for determination of sarcoidos...

Splenic sarcoidosis mimicking neoplastic disease
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...
