Abstract

Endometriosis is defined as the presence of a functioning endometrium outside the uterus. Abdominal wall endometriosis is a rare entity.

Usually both epithelium and stroma are seen, but occasionally the diagnosis of endometriosis can be made when only one component is present.1 It occurs in 8-15% of women of reproductive age group. It can involve a variety of extrauterine locations - both genital and extra-genital. Extra-genital endometriosis can be seen in such varied locations as intestines, lungs, pleura, kidneys and surgical scars. Cutaneous endometriosis is usually seen in abdominal scars following obstetric or gynaecologic surgery. Surgical scar endometriosis following cesarean section has an incidence of 0.03%-0.4%. It can be clinically confused with abscess, suture granuloma, hematoma, desmoid tumor, or primary and metastatic cancer.2

We report a case of scar endometriosis following caesarean section and diagnosed by fine needle aspiration cytology (FNAC).

There are very few cases of endometriosis diagnosed by FNAC

Scar endometriosis is a rare condition that affects women of reproductive age because of typical clinical history and clear-cut cytomorphological features. Cytodiagnosis of scar endometriosis was rendered without any difficulty in this patient. Thus, FNAC is an inexpensive, rapid and reliable method to conclude the diagnosis before surgery.
