FIGURE 1.

Encapsulated myoepithelioma of soft tissue with squamous and adipocytic metaplasia. A, Hematoxylin and eosin (H&E) stain, ×40 magnification of the excised specimen shows an encapsulated and heterogenous myoepithelial tumor with wellformed ducts and calcifications. B, H&E, ×100 magnification with adipocytic differentiation adjacent to squamous metaplasia containing keratin whorls. C, H&E, ×200 magnification nests of small epithelioid cells with regular ovoid nuclei, fine chromatin, inconspicuous nucleoli, and eosinophilic cytoplasm, disposed in a chondromyxoid and collagenous stroma. D, p63 stain, lesional cells stain indicating a myoepithelial origin. E, EMA stain highlighting ductal structures. F, S100 stain further identifies the tumor as a myoepithelioma.
