Pregnancy Luteoma Mimicking Ectopic Pregnancy: A Self-Resolving Lesion Undergoing Surgical Excision

Pregnancy luteoma (PL) is a rare condition, characterized by solid proliferation of luteinized cells. Most patients are asymptomatic; however, virilizing symptoms are seen in 25% of cases. They are usually detected incidentally. Here, we present a case where the patient presented with 6 weeks of amenorrhoea and acute abdominal pain with a positive urine pregnancy test. Clinically, she was diagnosed as a case of ovarian ectopic pregnancy; laparotomy and later, ovariotomy were performed. On histopathology, the lesion was diagnosed as PL. Differential diagnoses include non-neoplastic conditions like ectopic pregnancy, hyperreactio luteinalis, and ovarian neoplasms. An accurate diagnosis is important since PL is a self-resolving, non-neoplastic lesion which usually does not require surgical excision.
