Polymorphic cutaneous sarcoidosis: A case report

Sarcoidosis (Besnier-Boeck-Schaumann disease) is a multisystem disease of unknown etiology with various cutaneous presentations. It is characterized by the presence of non-caseating ‘naked’ granulomas in the affected tissue. We report a case of polymorphic cutaneous sarcoid in a 39-year-old immunocompetent male. He was visited at our outpatient department with multiple asymptomatic red colored raised lesions on different parts of the body. His history was significant for smoking and diabetes mellitus of varying duration. Cutaneous examination revealed multiple well-defined erythematous plaques of various shapes and sizes with minimal scaling. His blood investigations were normal except for raised serum angiotensin converting enzyme levels. Radiological investigations showed reticulonodular, fibrotic changes and hilar adenopathy on the chest film. We report this case to apprise clinicians of the fact that cutaneous sarcoid is a great mimicker due to lesional polymorphism and could be mistaken for a common dermatosis like psoriasis in our case.
