Cystic Adenomatoid Tumour of Uterus – A Rare Entity
Journal Title: Scholars Journal of Medical Case Reports - Year 2016, Vol 4, Issue 11
Abstract
Adenomatoid tumour are rare tumours with an overall incidence of 1% in female genital tract. The cystic variant is extremely rare. These tumours occur in both male and female genital tracts and in extragential location like heart, adrenal, appendix, hernial sac, intestinal mesentery, liver, lymphnode, mediastinum, omentum, pancreas, peritoneum, pleura and umbilicus. Adenomatoid tumours are considered to be mesothelial in origin which is proved by immunohistochemistry and ultrastructurally. The histogenesis is being related to entrapment of pleuripotent mesenchymal cells and mesothelial inclusions. This article describes an interesting case of cystic adenomatoid tumour occurring in a 55 years old post menopausal female who presented with abdominal pain. Ultrasonography showed an adnexal lesion arising from left ovary with other possibilities of atypical myoma or intramural haemorrhagic cyst. On macroscopy, the uterus showed a subserosal circumscribed lesion with honey comb appearance. Microscopically the cysts were lined by flattened to cuboidal cells with intervening fibromuscular stroma. Immunohistochemistry showed positivity of these lining cells to HBME-1, Pancytokeratin and focal positivity for Vimentin. Thus to conclude adenomatoid tumour are rare, cystic variant being extremely rare. A strong suspicion of this entity can aid in early diagnosis and excluded other cystic lesions and invasion of a endometrial or a cervical carcinoma when the two co-exists. Keywords: Adenomatoid, cystic, mesothelial, carcinoma.
