Histologic and immunohistochemic features of soft tissue MMP tumors. (a) Case 1 showing variably eosinophilic or clear cytoplasm and uniform ovoid-to-tapering nuclei. (b) Case 4 showing focally prominent ductal differentiation, embedded in a myxoid matrix (‘mixed tumor’). (c) Case 5 showing uniform cytomorphology with a mixed fascicular and trabecular architecture. (d) Immunohistochemic staining showing positivity for keratin AE1/AE3 in a trabecular clear cell area of case 1. (e) S-100 protein expression in the salivary gland lesion (case 6).
