Background: The drug-induced sarcoidosis-like reaction (DISR) is a condition clinically and pathologically similar to sarcoidosis but is induced by certain drugs. A few cases of DISR associated with the use of TNF-α antagonists have been reported in the literature.
Case Report: A 49-year-old female patient with a diagnosis of Crohn's Disease under treatment with adalimumab presented with a 2-month-long ulcerated swelling in the left lower fornix. Histological analysis of the biopsy specimen revealed multiple non-caseating granulomas multinucleated cells and epithelioid macrophages surrounded by lymphocytes. The lesion is under symptomatic control with a topical corticosteroid, and the patient is being monitored for manifestation in other organs and systems.
Conclusion: Lesions of DISR may occur isolated in the oral mucosa. Therefore, this complication must be considered in the differential diagnosis of oral granulomatous lesions in patients under treatment with anti-TNF-α drugs.

Background And Objectives: Drug-induced sarcoidosis-like reaction (DISR) is an adverse event with emerging importance during immune checkpoint inhibitor (ICI) treatment in melanoma patients. Its reported frequency varies widely, making accurate diagnosis crucial. Distinguishing DISR from tumor progression is challenging, and misdiagnosis may lead to detrimental treatment changes.

Drug-induced sarcoidosis-like reaction (DISR) is a rare adverse event associated with immunotherapy. Currently, there is no standardized treatment protocol for DISR linked to immune checkpoint inhibitors (ICIs). This study presents a case of an early-stage triple-negative breast cancer (TNBC) patient who developed hepatic sarcoidosis-like reactions during neoadjuvant pembrolizumab therapy.

The patient was a 54-year-old woman with chronic myeloid leukemia. Ten months after treatment with dasatinib, she developed a cough. Imaging studies showed ground-glass patterns in the lower lung fields of both lungs, which led to suspicion of drug-induced lung injury and prompted discontinuation of dasatinib.

A drug-induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction indistinguishable from sarcoidosis and is associated with the administration of a medication. It typically exhibits a temporal relationship with the initiation of the drug (an average interval of 22 months) and tends to improve upon its discontinuation. Tumor necrosis factor (TNF) antagonists, including adalimumab, have been associated with the development of DISR.
