[Primary cutaneous granulomatous alternariosis]

We report on a case of primary cutaneous granulomatous alternariosis on the forearm of a 65-year-old man who is otherwise in a good health. Histological examination revealed a predominantly histiocytic granuloma with numerous large cells containing fragments of fungi. The granuloma contained septate fungal hyphae and macroconidiospores. By means of macro- and micro-cultures the fungus was identified as an Alternaria species.
