Unusual case of granulomatous dermohypodermitis with giant cells and elastophagocytosis

A 27-year-old man presented with a reddish hard-elastic plaque on his back near the right armpit, which had slowly developed during 1 year. A granulomatous infiltration with many giant cells which were phagocytizing lymphocytes and elastic fibers was seen at histological examination. The lesion was removed and no new lesions developed after surgery. This case may represent a localized form of Convit's 'Progressive atrophying chronic granulomatous dermohypodermitis' or a rare form of 'Maladie de Besnier-Boeck-Schaumann chalazodermique', but it is also possible that it is a new entity never described before.
