Myoepithelial Carcinoma of the Thigh after Lipoma Excision

When these tumors occur in the oropharynx or nasopharynx symptoms such as nasal obstruction, ear fullness, and otitis media can occur.3' 4 Therefore, when these masses occur in areas such as the thigh, diagnostic imaging such as CT and MRI allow for anatomy and extension of the tumor to be better delineated. Among 31 cases with high-grade atypia, 42 per cent recurred locally and 32 per cent metastasized. in the case described here, the tumor had a nodular growth pattern with anastomosing cords of large and polygonal cells with abundant amphophilic cytoplasm and large oval nuclei with fine chromatin and single nucleoli on a background of chondromyxoid stroma (see Figs. 1 and 2). Tumor cells in this case were positive for vimentin, EMA, smooth muscle actin, calponin, and faintly positive for cytokeratin AE1/AE3, compatible with a diagnosis of malignant myoepithelioma.
