Lipogranuloma esclerosante escrotal primario simulando un tumor testicular. Presentación de un caso

Sclerosing lipogranuloma (SLG) of the male external genitalia is a rare benign condition which presents as subcutaneous masses. The underlying pathological process is a granulomatous reaction of fatty tissue. The cause of this disease is unclear but in many cases lipid degeneration secondary to injection of foreign bodies (secondary SLG) has been proposed. However, endogenous lipid degeneration from other causes such as infection, trauma, and allergic mechanisms has also been reported as primary SLG. Here we present a case of a 23-year-old man with apparent primary SLG of the external genitalia (scrotum). The pathological features and clinical management are discussed.
