Rare Broad Ligament Cavernous Hemangioma Mimicking Advanced Endometriosis: A Case Report

Cavernous hemangioma within the female genital tract is an extremely rare pathology, characterized by irregular vascular spaces containing blood or thrombus. We present a unique case of a 42-year-old primiparous woman who presented with typical endometriosis symptoms such as dysmenorrhea, dyspareunia, and heavy menstrual bleeding. The patient also experienced complex postpartum symptoms, which were misdiagnosed as cholecystitis and retained placental products. Imaging studies suggested deep infiltrative endometriosis with extraovarian endometriotic lesions. Surgical exploration revealed a hemangioma within the right anterior broad ligament alongside peritoneal endometriosis lesions. The hemangioma itself expresses estrogen and progesterone receptors in stromal cells. The presence of steroid hormone receptors strongly suggests symptom alleviation during the menstrual cycle and the postpartum period. The coexistence of cavernous hemangioma and endometriosis in the broad ligament, previously unreported, and symptomatic overlap between the two conditions complicates diagnosis and management, emphasizing the need for comprehensive evaluation integrating clinical symptoms and imaging findings.

Cavernous hemangioma of corpus imitating endometrial polyp in a young non-pregnant woman: A case report study

Key Clinical Message

Cavernous hemangiomas are rare and have various non-specific clinical presentations, such as menorrhagia. It can mimic different diseases such as endometrial polyps. Pathologists and gynecologists should be aware of performing histopathological examinations of this neoplasm for accurate diagnosis and to avoid unwarranted therapeutic interventions.

Abstract

Internal genital tract hemangiomas are rare and can be divided into capillary and cavernous. We present a rare case of cavernous hemangioma (CH) of the corpus in a young, non-pregnant woman. The patient was a 28-year-old woman who had complained of menorrhagia for 2.5 years. Sonography showed a hypoechoic intramural area measuring 35 × 23 mm. Histomorphology revealed neoplastic proliferation of dilated thin-walled arteries of various sizes within the myometrium. Due to the variable clinical presentations of CH, histopathological examination should be performed for an accurate diagnosis. It is a rare entity and we recommend training pathologists and gynecologists on this neoplasm for accurate diagnosis and to avoid unwarranted therapeutic interventions.
