[Incomplete testicular feminisation]

We report a case of incomplete testicular feminisation in a 53 years old, third time married patient. Prominent symptoms were a slightly masculine structure of the body, masculine features and a hypertrophy of the clitoris. The reason for hospitalization was a lower abdominal tumour. Histologically it was a hydrocele with a testicle including a Leydig's cell-tumour without any signs of malignancy. On the opposite side was on atrophic testicle without spermiogenesis too. As usual the syndrome of incomplete testicular feminisation was discovered very late. Therefore, the necessary psychological guidance, especially from the beginning of puberty and the oncological control to exclude a tumour of the testicle had been left undone. It is the purpose of this report to draw attention to the aspect of this disease despite its rare occurrence in a ratio of 1:2,000 to 1:20,000.
