Disseminated Lipogranulomas and Sudden Death From Self-Administered Mineral Oil Injection

The cosmetic injection of exogenous lipids and more recently of polydimethyl siloxane (injectable silicone) into the scrotum has been described since 1899. Sclerosing lipogranuloma and paraffinoma are terms applied to a complication of this practice in which the injected oils or silicone elicit a marked granulomatous reaction with prominent surrounding fibrosis. Although this complication has been described as a localized process occurring mainly in the scrotal area and regional lymph nodes, few studies have documented systemic manifestations. In this report we describe the autopsy findings of a 48-year-old man who had scrotal and systemic lipogranulomas from repeated self-administered injection of mineral oil. In addition, severe acute pulmonary edema resulted in sudden unexpected death. To our knowledge, this fatal complication of exogenous lipogranuloma has not been previously reported.
