Objective  To report three patients with persistent Müllerian duct syndrome (PMDS) associated with a unilateral testicular tumour. Patients and methods  Three adults with PMDS and an associated testicular malignancy were evaluated using physical examination, imaging, measurement of tumour markers, surgical exploration and chromosome analysis. Results  The position of the uterus and fallopian tubes differed in all patients; one was in the scrotal sac, another in the abdomen and the third in the left inguinal canal. Two of the patients were cousins and their pedigree showed that they were probably in a sex‐limited group. Both also had transverse testicular ectopia; fertility was documented in the younger patient. In all cases, the karyotype was proved to be 46, XY. Conclusion  We recommend that the diagnosis of PMDS is made radiologically and that the detection of Müllerian inhibiting factor is mandatory. As malignancy does not occur in the retained Müllerian ducts, hysterectomy should not be performed at abdominal exploration, although orchidectomy should be, because orchidopexy offers only limited protection against future malignancy if performed after 2 years of age. It is not necessary to perform testicular biopsy to detect tumour in the scrotal testis in this syndrome, because an impalpable tumour can be localized by ultrasonography.

Primary penile carcinoma is one of the rarest male genital tract tumors. We rarely encounter this malignancy in Turkey because circumcision is routinely performed as a part of the Islamic tradition. Despite the medical paradox that the penis is rarely affected by metastases, approximately 300 cases have been reported in the literature. The primary lesion is almost 75% of pelvic origin; genitourinary or rectosigmoid primaries and penile metastasis from extrapelvic primaries constitute 25% of other primaries. Furthermore, isolated metastatic penile carcinomas are exceptionally rare. The rarity of the event prompted this study, which describes 10 cases of metastatic tumors of the penis including 7 cases with transitional cell carcinoma of the bladder, and in 1 case each of squamous cell carcinoma of the lung, adenocarcinoma of the prostate and leukemia. The main characteristics of the primary tumor are described, along with the diagnosis, treatment and the outcome of patients.

Preoperative erectile function seems to be the best predictor of postoperative erectile function in patients who will undergo CABS.

Tumor metastases to the testes, excluding lymphomas and leukemias, are extremely uncommon. In the literature there have been reports of 236 different cancer metastases to the testis. The most common origin is the prostate in 76 (32%) cases. We report two addi-tional cases of testicular metastases from adenocarcinoma of the prostate. Immunohistochemical analysis of prostate specific antigen indicated that the metastatic cancer was of prostatic origin.
