Identify sarcoid-like reaction in cancer patients receiving chemotherapy and immunotherapy: dont get into the weeds of SUVmax

Conclusions: To avoid pitfall in PET/CT interpretation, it is important to recognize the sarcoid-like pattern of FDG uptake, which regardless of SUV value is favored to represent a benign rather than a malignant process.

ConclusionThis case sheds the light on a complex regulation of PD-L1 expression in vivo on PBMC after nivolumab arrest and triggers the question of monitoring the expression of immune checkpoint on immune cells during and after treatment with ICI.

We present a patient diagnosed with skin sarcoidosis, breast cancer, pulmonary tuberculosis, and peritoneal sarcoidosis with a past history of colorectal cancer. During stage work up for breast cancer, suspicious lesions on peritoneum were observed in imaging studies. Considering our patient's history and imaging findings, we initially suspected peritoneal carcinomatosis. However, the peritoneal lesion was diagnosed as sarcoidosis in laparoscopic biopsy. This case demonstrates that abdominal sarcoidosis might be considered as a differential diagnosis when there is a lesion suspected of being peritoneal carcinomatosis with ...

Discussion Flushing is usually thought of as a benign condition such as blushing, but can be quite irritating if it is frequent or persistent (i.e. menopausal hot flashes) or even pathologic (i.e. malignancy). “Flushing is a subjective and sensation of warmth that is accompanied by reddening of the skin anywhere on the body but favors the face, neck, and upper torso…. Flushing can be broadly divided into episodic or persistent. Episodic flashing is mediated by the release of endogenous vasoactive mediators or medications, while persistent flushing result in a fixed facial erythema with telangiectasias and cyan...

This study aimed to evaluate the diagnostic yield of fiberoptic bronchoscopic (FOB) transbronchial biopsy and its relation with quantitative findings of high resolution computerized tomography (HRCT). A total of 83 patients, 19 males and 64 females with a mean age of 45.1 years diagnosed with sarcoidosis with complete records of high resolution computerized tomography were retrospectively recruited during the time period from Feb 2005 to Jan 2015. High resolution computerized tomography scans were retrospectively assessed in random order by an experienced observer without knowledge of the bronchoscopic results or lung func...

Regulatory B-cells (Breg) play an important role in reducing autoimmunity and reduced levels of these cells are implicated in etiology of several auto-inflammatory diseases. Despite their impact in many diseases, their physiological inducers are unknown.   Given that Bregs are a very rare B-cell, identifying factors that promote their development would allow in vivo modulation of Breg levels and ex-vivo production of large amounts of antigen-specific Bregs to use in immunotherapy for auto-inflammatory diseases.  Researchers at NEI'sMolecular Immunology Section developed a method for theex-vivo production of Breg...

The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today’s standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging. Sarcoidosis is a multisystemic granulomatous disease characterized by an aberrant immune response to unknown antigens, whereas sarcoid-like reactions (SLRs) refer to localized clinical features. We carried out a single-center observational study in patients with stage IIB–IV melanoma treat...

yer N Abstract The development of immune checkpoint inhibitors (monoclonal antibodies targeting PD-1/PD-L1 or CTLA-4) represents a significant advance in the treatment of multiple cancers. Given their particular mechanism of action, which involves triggering CD4+/CD8+ T-cell activation and proliferation, they are associated with a specific safety profile. Their adverse events are primarily immune-related, and can affect practically all organs. In this context, dermatological toxicity is the most common, though it mostly remains mild to moderate and does not require discontinuation of treatment. More than a th...
