Clinical and histological findings. On the right arm (A) erythematous nodules (B) were found in a sporotrichoid-like manner. At the back (C) a sharply marginated erythematous plaque (D) was seen. The histopathology of the skin revealed in the dermis disseminated caseating partly epitheloid cell granulomas with a marginal zone of lymphocytes and a subepidermal lymphohistiocytic infiltrate with perivascular accentuation (E). Close up of an epitheloid cell granuloma (F).

A 48-year old man presented with multifocal nodules of variable size arranged in a sporotrichoid-like manner on the right arm, the dorsum of the digit IV, the left arm, the right side of his back, the knees and a partly circumscribed erythematous plaque on his back (Figure 1A-D). They revealed caseating epitheloid cell granuloma in the dermis with a marginal zone of lymphocytes and a subepidermal lymphohistiocytic infiltrate with perivascular accentuation (Figure 1E, F).
