[Sclerosing lipogranuloma of the male genitals].

We report on a 23-year-old male patient showing sclerosing lipogranuloma of the genitalia and surface ulceration of the penis. Histologic investigation revealed a granuloma of the foreign body type spreading both dermally and subcutaneously and showing cavities of varying sizes, resembling Swiss cheese, which were partly coated with macrophages. Histochemical tests with Sudan Ill, Sudan-black B and OsO4, as well as chromatographic analysis confirmed the presence of a hydrophobic unpolar lipid, such as liquid paraffin.
