Perineal neoplasms.

Experience with 2 cases of neurally-derived perineal masses is described. A relevant review of the literature spanning 50 years revealed 36 cases of perineal neoplasm of diverse nature, disclosing that such lesions typically present as otherwise asymptomatic enlarging masses and may comprise a broad spectrum of neoplasia with diagnosis and prognosis often relating to the age of the patient. Management naturally relates to tissue type and degree of local involvement.
