title: [Angiomyxoma: always myxoid, sometimes aggressive].
abstract: Angiomyxoma is a distinct soft tissue tumor characterized by the presence of     prominent myxoid matrix and numerous thin-walled blood vessels. This tumor has a     predilection for the trunk, head and neck, extremities, and genitalia. It is a     benign tumor and total excision is curative. Recurrence is rare except for     aggressive angiomyxomas. A 12-year-old girl with a 10-year history of a     subcutaneous mass on the left gluteus measuring 4.5x4x3 cm had been referred.     The tumor was encapsulated and was located in the reticular dermis and     subcutaneous tissue, composed of stellate cells with mucinous stroma.     Thin-walled blood vessels were prominent. Immunohistochemically, tumor cells     were immunoreactive for vimentin. No immunoreactivity was present for estrogen     receptor, CD34, smooth muscle actin, S-100 protein and desmin. The purpose of     this report is to present a classical example of an isolated superficial     angiomyxoma and discuss the differential diagnosis, because of its relatively     infrequent occurence.
