title: Gynaecomastia and occult Leydig cell tumour of the testis.
abstract: Two patients with Leydig cell tumours of the testis are described. Both presented with gynaecomastia, but on initial examination had apparently normal testes. The causative tumour did not become obvious for some months, despite being carefully sought. Review of the literature suggests that gynaecomastia preceding a readily palpable tumour is a recognised problem. The detection and management of Leydig cell tumours of the testis are discussed.
