TUMORAL SARCOIDOSIS

Introduction. We report here an unusual tumoral form of cutaneous sarc oidosis which lead to diagnostical difficulties. Case report. A 56 yea r-old woman was hospitalized for a large lumbo-sacral tumor which size had rapidly increased. The tumor was purplish-red, firm, measured 10 x 20 cm and the patient was unable to sit normally. The biopsies demon strated a dermohypodermal epithelioid and giant cell granuloma without necrosis. We ruled out an infectious granuloma and a foreign body gra nuloma. There were no extra-cutaneous localizations. This sarcoidal tu mor cured with systemic corticosteroids. Discussion. Tumoral cutaneous forms of sarcoidosis are uncommun; 3 other cases of the literature ar e reported. Before to state positively this forms it is obligatory to rule out all the other aetiologies of sarcoidal granuloma. The existen ce of extracutaneous localizations and multiple skin localizations is helpful to diagnose this uncommon type of sarcoidosis.
