Adenocarcinoma of the rete testis is a rare neoplasm with 41 reported cases in the literature till 1994. In most of the reported cases, the neoplasm presents as a scrotal mass with diffuse enlargement. The aetiology is unknown and the clinical course of the tumour is not very well defined. In six of the reported cases metastatic spread of the tumour to inguinal lymph nodes was demonstrated in the follow-up. We report herein a distinctive case of rete testis adenocarcinoma presenting as an isolated inguinal recurrence one year after radical orchiectomy.
