Uterine lipoma

Area of Science:

• Gynecologic Pathology
• Uterine Neoplasms
• Medical Imaging

Background:

• Pure lipomas of the uterus are exceptionally rare, often presenting diagnostic challenges due to symptom overlap with more common uterine tumors like leiomyomas.
• The histogenesis of uterine lipomas remains poorly understood, contributing to diagnostic uncertainties.
• While typically diagnosed post-operatively or at autopsy, advances in imaging offer potential for preoperative identification.

Observation:

• A 67-year-old postmenopausal woman presented with pelvic pressure and urinary symptoms, clinical signs mimicking other uterine pathologies.
• Imaging studies, including computed tomography and magnetic resonance imaging, are increasingly recognized for their potential in preoperative diagnosis of uterine lipomas.
• Pathological examination confirmed a pure intramural lipoma of the uterus, characterized by specific morphological and histological features.

Findings:

• The case presented a pure intramural lipoma of the uterus, a rare benign tumor.
• Histological evaluation confirmed the absence of any sarcomatous components, differentiating it from malignant uterine neoplasms.
• The findings underscore the importance of considering lipoma in the differential diagnosis of uterine masses.

Implications:

• Accurate preoperative diagnosis of uterine lipomas can be achieved through advanced imaging techniques, aiding surgical planning.
• Distinguishing uterine lipomas from leiomyomas and other uterine tumors is crucial for appropriate patient management.
• Further research into the histogenesis of uterine lipomas may improve understanding and diagnostic accuracy.
