THE undescended testis is more susceptible to trauma (Gross and Jewett 1956) and to malignant change (Collins and Pugh, 1964; Altman and Malament, 1967) than the normally placed testis. It has been shown that degeneration in an ectopic testis begins at about the age of 5 years (Scorer 1967; Cohn 1967). It is therefore generally accepted that orchidopexy should be carried out at around the age o...

The rupture of an intra-abdominal testicular neoplasm is a rare cause of acute abdomen and massive intra-abdominal haemorrhage. We report the case of a 70-year-old male presenting a massive intra-abdominal bleeding caused by a Leydig cell tumour in an undescended testis. The clinical details and pathology of this rare testicular tumour are discussed.

CONTEXT Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. OBJECTIVE To provide recommendations for the diagnosis and treatment of...
