Spontaneous localized lipogranuloma of the spermatic cord.

Four cases of localized lipogranuloma of the spermatic cord without evident predisposing factor, are presented. The mass was associated with a small vaginal hydrocele. Wide excision of the intact mass proved successful in all cases. There was no recurrence or regrowth up to one-year follow up. At histology a lipogranuloma was diagnosed but its cause could not be assessed. A spontaneous specific tissue reaction of the cord tunics to an unknown injury, is hypothesized.
