A: The cells are in disorganized fascicles with pleomorhism, nuclear atypia and neoplastic spindle cells with wavy eosinophilic cytoplasmic processes. (H & E; bar 20 μm; ×400). B: the neoplastic cells form dense bundles separated by scanty collagenous stroma. Notice bland nuclei lacking atypia. (H & E; bar 30 μm; × 400) C: Upon histopathological examination of the ulnar mass, neurofibroma with a mixture of round and spindle shaped cells, mitotic figures, infiltrates of various numbers of lymphocytes and hypercellularity arrangement was diagnosed.
