Isolated Lipoma of Uterus – A Rare Case Report With Histopathological Correlation

Pure lipoma of the uterus is an extremely rare tumour, even though lipoma is the most common soft tissue tumour overall. The lipomatous tumours constitute 0.03% - 0.25% of all the uterine neoplasms, and pure lipoma of the uterus is even rare. It is a benign tumour composed purely of mature fat cells (adipocytes). CT finding and Ultrasonography is usually non-specific. Although MRI is useful to identify the fatty nature of the lesion, preoperative diagnosis is seldom made. It may be misdiagnosed clinically or on imaging as a leiomyoma with fatty degeneration, or even a malignant tumour. This case report emphasizes on a 70-year-old female who presented to the gynaecology department with pain abdomen for the past 6 months. MRI showed post- menopausal uterus with altered signal intensity area in the anterior wall, concerning for uterine Lipoleiomyoma. Basis the intra-operative frozen section findings and histopathological evaluation, the final diagnosis of pure uterine lipoma was made.
