SARCOIDOSIS (BESNIER-BOECK-SCHAUMANN'S DISEASE)

Abstract

SARCOID was formerly described in the textbooks of dermatology as a tumor-like or nodular formation usually located in the layers of the subcutaneous tissue of the face, the extensor surfaces of the arms and the trunk, showing a dark red, violaceous or brownish discoloration of the skin and not undergoing necrosis or ulceration but sometimes leaving an atrophic scar of the epidermis.¹ In 1910, Darier² described four types of sarcoids. (a) Boeck's multiple benign sarcoid, or miliary lupoid; (b) subcutaneous sarcoid of Darier-Roussy, (c) indurated erythematous sarcoid of the extremities, and (d) Spiegler-Fendt sarcoid. The second type is localized to the hypodermis and shows a tendency to undergo necrosis or ulceration. It is considered a true nodular tuberculosis of the skin. The third type is a condition related to Bazin's erythema, which is also included among the exanthematous forms of cutaneous tuberculosis. The last type was also found
