Ovarian lipoleiomyoma: a rare benign tumour

The excised mass was nodular and encapsulated; the cut section was yellowish with scant grey–white whorled areas. Microsections showed a mature adipose tissue admixed with leiomyomatous areas without cellular atypia and adjacent compressed ovarian tissue. Immunohistochemical staining showed diffuse positive reaction for desmin confirming that spindle cells were smooth muscle cells. A diagnosis of lipoleiomyoma of the ovary was made based on the radiological, histopathological and immunohistochemical findings.

It can also be occasionally misdiagnosed as sarcoma on clinical …
