This article reports a case of angiomatoid fibrous histiocytoma (AFH),
a rare fibrous tissue tumor with unique clinical characteristics, For
merly, this tumor was classified as angiomatoid malignant fibrous hist
iocytoma. First described in 1979, AFH was felt to be a variant of mal
ignant fibrous histiocytoma (MFH), One dominant characteristic that di
fferentiates this tumor from the remainder of MFH subtypes is that it
most often presents in individuals younger than 20 years of age, The u
sual MFH occurs in the seventh decade of life, Because of its rarity,
AFH has been difficult to classify and, during this current year, has
been designated as a separate entity, rather than a subtype of MFH. Cl
inically, the tumor presents as a soft-tissue mass in the subcutis or
deep dermal layers of the body, often presenting on the extremities or
neck, Local recurrence has been reported, but mortality figures are v
ery favorable and wide local removal is sufficient treatment.
