Adrenal Crest in Testicular Tissue of an Undescended Testis in an Adult Patient: A Case Report.

This case report describes a rare occurrence of ectopic adrenal cortical tissue (EACT) in the undescended testis (UDT) of an adult male patient. The patient presented with an empty left scrotum since birth, and a magnetic resonance imaging (MRI) confirmed the diagnosis of left-side UDT. Orchidectomy was performed, and a microscopic examination revealed a UDT with EACT. The patient had no significant medical or surgical history and had a normal preoperative hormonal profile. EACT is usually found incidentally during surgical procedures and is more common in children than adults. This case emphasizes the importance of investigating adrenal rests due to the potential of neoplastic transformation or hormonal activity. The case report concludes that EACT of the UDT is still a possibility in the adult patient population.
