title: Subcutaneous nodules as the first clinical manifestation of sarcoidosis.
abstract: We report the case of a 61-year-old male who presented with a febrile illness accompanied by arthralgia and myalgia. Two months later he developed multiple subcutaneous nodules and enlarged parotid glands. Later two erythematous plaques, clinically compatible with erythema nodosum (EN), were observed. Laboratory investigations revealed abnormal levels of angiotensin converting enzyme and chest radiography showed bilateral hilar enlargement. The biopsy of the cutaneous lesions demonstrated multiple non-caseating granulomas in the subcutaneous tissue without any alterations in the epidermis and the dermis. The cultures for Mycobacteria and fungi were both negative. The clinical picture and histopathological findings were compatible with subcutaneous nodular sarcoidosis. The response to steroid treatment was satisfactory.
