Eosinophilic sclerosing lipogranuloma of the male genitalia not caused by exogenous lipids.
A type of sclerosing lipogranuloma of the male genitalia that is different from cases caused by injection or application of foreign bodies is reported in 4 patients. The characteristics of the disease are a symmetrical Y-shape of the granuloma, spontaneous regression, severe infiltration of eosinophils in the granuloma, eosinophilia of the peripheral blood and absence of any exogenous lipids by chemical analyses of the granuloma tissue. Ultrastructural study showed intracytoplasmic fat vacuoles of varied size in histiocytes and multinuclear giant cells. This is a new type of sclerosing lipogranuloma of the male genitalia and the pathogenesis of the disease is still unknown.
