Programmed cell death 1 blockade-induced cutaneous sarcoid-like epithelioid granulomas in advanced melanoma: A case report

Abstract

Sarcoidosis is a chronic, systemic inflammatory disorder of unknown etiology that is characterized by the formation of noncaseating granuloma in affected organs, most commonly the lung.1 In pulmonary sarcoidosis patients, the T helper 1 (Th1) cytokine profile of CD4+ as well as CD8+ T cells was demonstrated in bronchoalveolar lavage fluid.2 However, there has been no detailed description of a lymphocyte profile in cutaneous sarcoid-like epithelioid granulomas. Here, we report a case of sarcoid-like epithelioid granulomas induced by nivolumab in a patient with advanced melanoma and we performed functional lymphocyte analysis of the granuloma lesions. All studies were performed in accordance with the ethical principles of the Declaration of Helsinki.
