RESUMEN
BACKGROUND: Adenomatoid tumors are regarded as distinctive benign mesothelial neoplasms of the paratesticular region, most commonly occuring at the tail of the epididymidis.Because of its rarity, the clinical and histopathological aspects are discussed. CASE PRESENTATION: We present the case of a 41-year-old patient with an adenomatoid tumour located in the tail of the left epididymis that referred to our department with gradual enlarged intrascrotal mass. The diagnosis was achieved by echography, and was confirmed by surgical excision and histological analysis. CONCLUSION: Due to its low incidence in intrascrotal pathology, we believe it is important for the physician to be aware of this interesting entity in order to make a differential diagnosis from other inflammatory processes and to adopt the proper surgical approach.
