Angioleiomyoma may be rare, but it can dramatically mimic far more common gynecologic conditions—an issue highlighted in a new case report published in Oncoscience. The study focuses on cervical angioleiomyoma, a benign soft-tissue tumor arising from smooth muscle cells in and around blood vessels, yet capable of presenting with persistent menorrhagia and pelvic pain.
The patient described is a 26-year-old woman who developed irregular cycles and chronic heavy menstrual bleeding over several months. She also reported intermittent pelvic discomfort. Because prolonged blood loss caused moderate anemia, the clinical picture initially resembled typical uterine disorders rather than an uncommon tumor entity.
Pelvic examination revealed a large cervical mass, approximately 6 cm in size. First-line imaging with transvaginal ultrasound suggested possibilities such as a cervical fibroid or cervical polyp, underscoring how overlapping symptoms and appearance can delay accurate diagnosis when the condition is not on the differential.
To refine the assessment, clinicians turned to magnetic resonance imaging (MRI). The scan demonstrated a well-defined cervical mass with high signal intensity on T2-weighted sequences—an imaging pattern consistent with a prominent vascular component. These features helped shift suspicion toward angioleiomyoma, guiding the decision to pursue complete surgical excision via a vaginal approach.
Histopathology provided the diagnostic confirmation. Microscopy showed spindle-shaped smooth muscle cells arranged in a perivascular pattern around thick-walled blood vessels, with no evidence of malignancy. Immunohistochemical staining further strengthened the conclusion: smooth muscle antigen (SMA) and CD34 were positive, matching the expected profile for angioleiomyoma.
After surgery, the outcome was clinically striking. At three-month follow-up, the patient reported full resolution of both heavy menstrual bleeding and pelvic pain, with no postoperative complications reported. The case reinforces that—while alarming in symptoms—this tumor type is benign and often curable with complete removal.
The authors also reviewed prior literature, noting that cervical involvement is only a small fraction of female genital tract angioleiomyomas and that only a limited number of cervical cases have been documented. They emphasize that MRI can better reveal vascular characteristics, while definitive identification relies on histopathological evaluation combined with immunohistochemistry.
For clinicians and patients alike, the message is clear: cervical angioleiomyoma should enter the differential diagnosis when young patients present with persistent heavy menstrual bleeding and pelvic pain that does not fit neatly into more common categories. Early recognition can support fertility-preserving, targeted care—and reduce the uncertainty that comes from prolonged diagnostic ambiguity.
