She h ad noticed a sudden enlargement with erythemateous change of the overlying skin during the past eight months. It was mildly painful when she exerted p ressure on it. Physical examination revealed a somewhat firm and mobile mass of approximat ely 6 x 5 cm in size, located on the lateral aspect of the upper left forea rm. The tumoral mass was partly fixed to deeper tissues. There was no regio nal nodal involvement. Incisional biopsy was performed.
