title: Sclerosing lipogranuloma of male genitalia. Review of 23 cases.
abstract: In 1950 the term "sclerosing lipogranuloma" was introduced to designate a praticular subcutaneous granulomatous reaction that was believed to be a "local reactive process following injury to adipose tissue." Subsequent reports have shown that exogenous lipid injections probably are responsible for this lesion. We have studied 23 cases involving penis, scrotum, spermatic cord, and perineum, nine of which had been previously reported. We have been able to identify paraffin hydrocarbons by means of infrared-absorption spectrophotometry in 21 of these cases. We belive this entity should be redefined as a "local reactive process following injection of exogenous lipids into the subcutaneous tissues." In conventional microscopical sections, the lesion must be differentiated from adenomatoid tumor, sclerosing liposarcoma, and lymphangioma.
