Abstract

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. Interestingly, in this case, imaging (contrastCT and MRI) had missed Mullerian structures due to varied presentation, but exploration and excision of the structures followed by their histopathology revealed uterine leiomyomas and confirmed other Mullerian structures (bilateral fallopian tubes, cervix) with bilateral testes.
