Persistent Mullerian duct syndrome: rare presentation in an elderly man.

Persistent Mullerian duct syndrome has been described as a disease of internal male pseudohermaphroditism, a rare autosomal recessive disease, characterised by persistent Mullerian derivatives in patients with male pattern 46, XY karyotype and normal pattern virilisation. We present a case of an elderly man, who on evaluation for bilateral undescended testes was found to have a pelvic mass suggestive of malignant transformation of an undescended testis on imaging. On surgical exploration, uterus with multiple fibroids, bilateral fallopian tubes, cervix and bilateral atrophic testes were identified.
