Cytodiagnosis of scar endometriosis: A case series

Introduction: Endometriosis is defined as the presence of hormonally responsive endometrial tissue outside the uterus. The overall prevalence is 8–15% in women of reproductive age group. Subcutaneous location causing a palpable lump that is amenable for cytodiagnosis is not common; most of the cases are sites of previous cesarean section or episiotomy site. Case Series: We report three cases of endometriosis that presented with subcutaneous palpable lumps in the anterior abdominal wall and perineal regions. All cases were diagnosed by fine needle aspiration cytology (FNAC) and confirmed by histopathology. Conclusion: Fine needle aspiration cytology is an easy, economical, fast and reliable method for the diagnosis of endometriosis in subcutaneous palpable lumps in clinically suspicious patients.
