Adenomatoid tumours: A short series with literature review

Adenomatoid tumours are hormone independent tumours of mesothelial origin. These are distinctive benign neoplasms usually localised in the epididymis in males and myometrium in females. They are uncommon and account for less than 5% of tumours in males and approximately 1% in females. Due to their rarity and distinct histomorphology, we present a case series of six adenomatoid tumours of which three were males and three were females, obtained over a period of five years at a tertiary hospital in South India. The diagnosis of this tumour in all the three women and in one of the male patients was incidental, and they underwent surgical procedure for other coexisting lesions. In two male patients swelling of the testis was present; however, the clinical diagnosis of both these patients was more sinister than a benign entity like adenomatoid tumour. The present series describe the histomorphological features of this entity and establish the unique histopathological findings of this tumour which is clinically subtle and is seldom recognised.
