Heterotopic adrenal gland in undescendent testis - Case report.

Heterotopic adrenal cortex is usually found in the kidney, retroperitoneum and spermatic cord. The adrenal gland has a dual embryonic origin: the cortex arises from the mesoderm and the medulla from ectoderm of the neural crest. Adrenal cortex and gonads both arise from genital ridge, because of that adrenal tissue with descending gonads may migrate in early embryonic period. We report a case of adrenal rest in upper pole of testes.
