Diagnosis of scar endometriosis on aspiration cytology and cellblock: Myth or reality.

Abstract

Endometriosis is defined as the presence of endometrial tissue outside the uterus. It can occur both in the pelvic and extra pelvic regions. Abdominal scar endometriosis is a rare type of extra pelvic endometriosis that occurs after surgery involving the uterus. In the post-cesarean section, the development of scar endometriosis is a rare event and the diagnosis of scar endometriosis is usually confirmed after surgical excision and histopathological examination. We present a case of an abdominal lump in a 26-year-old female with a myriad of clinical differential diagnoses, which was rendered a confirmed diagnosis of scar endometriosis with the help of fine-needle aspiration cytology and cell block aided with immunohistochemistry.
