superficial angiomyxoma

superficial angiomyxoma

A solitary, slow-growing, infiltrative superficial tumour averaging 3.5 cm, which is found on the trunk, genitalia, head and neck, and limbs, and is classically associated with Carney complex.

Management
Surgery; no recurrence.

The differential diagnosis of acral fibromyxoma includes superficial angiomyxoma, perineurioma, and myxoid neurofibroma.
Differential diagnosis of myxoid DFSP is diverse and the lesion may be easily confused with a few myxoid neoplasms, such as myxoid neurofibroma, superficial angiomyxoma, myxoid liposarcoma, and low-grade myxofibrosarcoma.
Fibroepithelial stromal polyp, superficial angiomyxoma, angiomyofibroblastoma, cellular angiofibroma and smooth muscle tumours also need to be considered in the differential diagnoses of a polypoidal mass in the perineum.

There are 5 entities commonly accepted as myxomas: intramuscular myxoma, juxta articular myxoma, superficial angiomyxoma (or cutaneous myxoma), aggressive angiomyxoma (usually pelvic and perineal regions) and myxoma of nerve sheath (myxoid neurothekeoma).

INTRODUCTION: Superficial angiomyxoma is a rare benign tumour of dermis and subcutis which was first described by Carney and colleagues in 1986 as a cutaneous myxoma of carney's complex.
The differential diagnosis of aggressive angiomyxoma includes fibroepithelial stromal polyp, angiomyofibroblastoma, myxomas, superficial angiomyxoma, myxoid neurofibroma, myxoid liposarcoma, and myxofibrosarcoma.
The differential diagnosis of AAM includes angiomyofibroblastoma, superficial angiomyxoma, fibroepithelial stromal polyps, myxoid lipomatous tumors, and myxoid leiomyoma.
Also in the differential diagnosis is superficial angiomyxoma.[8] Although this lesion has much microscopic overlap with our case, superficial angiomyxoma has a characteristic nodular architecture, acellular myxoid clefts, and is grossly well-demarcated; none of these features was seen in our case.
Because of their CD34 positivity and the presence of spindle-shaped and stellate cells embedded in a vascular, basophilic matrix, SAFMs can be confused with superficial angiomyxomas. In contrast to SAFMs, angiomyxomas are dermal and subcutaneous nodules, which may contain an epithelial component, and affect any body part, especially the head, neck, and trunk.
