(AA), which is an infiltrative myxedematous mesenchymal tumor with the potential for local recurrence .
The medical literature suggests that about 3 out of 10 (30%) aggressive angiomyxoma

mostly affects women and arises in the perineal and pelvic regions.
On immunohistochemistry both angiomyofibroblastoma-like tumor and aggressive angiomyxoma
are positive for Desmin and SMA.
The differential diagnosis of intramuscular myxomas includes also aggressive angiomyxoma
, myxoid neurofibroma, myxoid liposarcoma, cellular or juxta-articular myxoma, and nodular fasciitis [18, 19].
(AA) is a rare soft-tissue tumor that is typically found in the perineum of females of reproductive age.

: members of a spectrum of genital stromal tumours?]," Ann Pathol.
The differential diagnosis might include a myxoid tumor such as myxoid neurofibroma or aggressive angiomyxoma
due to the presence of myxoid, proteinaceous, or mucinous contents.
Cellular angiofibroma can also be confused with aggressive vulvo-vaginal tumours like aggressive angiomyxoma
and solitary fibrous tumour (1, 5).
