[Sclerosing lipogranuloma in a male].
INTRODUCTION: Major trauma was the only aetiologic factor found in a male patient presenting sclerosing lipogranuloma. This condition is well-known in women but is rarely described in men. CASE REPORT: A 31-year-old non-obese man with no sign of gynaecomasty presented with well-delimited plaques of pigmented and sclerosous tissue located at the pubis and both breasts as well as hard nodules of the scrotum and the penis. The lesion developed progressively after a major trauma involving the anterior aspect of the thorax and the public area. An inflammatory border persisted eight years after the initial trauma. Histological examination of a biopsy specimen showed evidence of adipocyte necrosis with lipophagia and lipogranuloma. No foreign body was found. DISCUSSION: The diagnosis of post-trauma cytosteatonecrosis was retained on the basis of the clinical history and the clinical, histological and radiographic evidence. This condition is a well-identified clinical entity which is sometimes confounded with false panniculitis resulting from self-injection of oily products. The endogenous origin of the fatty acids found within the cytosteatonecrosis tissue has recently been proven. Usual localizations are the breast in women and genital organs in men. Favouring factors in women include obesity, age, anticoagulants, frequency and intensity of trauma. The exceptional localization in our patient was strongly related to the earlier trauma.
