Introduction:
We report here an unusual tumoral form of cutaneous sarcoidosis which lead to diagnostical difficulties.
Case Report:
A 56 year-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 demonstrated a dermohypodermal epithelioid and giant cell granuloma without necrosis. We ruled out an infectious granuloma and a foreign body granuloma. There were no extra-cutaneous localizations. This sarcoidal tumor cured with systemic corticosteroids.
Discussion:
Tumoral cutaneous forms of sarcoidosis are uncommon; 3 other cases of the literature are reported. Before to state positively this forms it is obligatory to rule out all the other aetiologies of sarcoidal granuloma. The existence of extra-cutaneous localizations and multiple skin localizations is helpful to diagnose this uncommon type of sarcoidosis.
