[Sclerosing lipogranuloma of the male genitalia: report of 2 cases--review of 72 cases reported in Japan].

Two cases of male patients (49 and 36 y.o.) with sclerosing lipogranuloma of the genitalia are reported. They denied having received any injection of exogenous substances or having suffered from any trauma. We discuss the clinical features and review previously published papers reporting similar cases. We would like to propose that sclerosing lipogranuloma that is not caused by the injection of exogenous substances should be dealt with as a new disease entity.
