简介
A granular cell tumor (GCT) is relatively uncommon and objectively diagnosed with neural markers on immunohistochemistry (IHC). Recent studies have described additional markers for a GCT. Herein, we present morphologic spectrum of 12 GCTs of soft tissues and skin, including 10 benign and 2 malignant subtypes with an optimal diagnostic IHC panel. Eleven cases occurred in women and 1 in a man, with a mean age of 45.5 years. Six cases occurred in soft tissues and skin of extremities, 4 in the breast soft tissues, and 1 case each in the back and preauricular region, respectively. Cytologic smears in 2 cases displayed polygonal cells with abundant, eosinophilic, granular cytoplasm. On histopathology, all cases invariably revealed a nonencapsulated infiltrating tumor comprising groups and nests of granular cells with vesicular nuclei. In 5 cases, granular cells were noted in close proximity to the nerves. Two …
