A case of palisaded encapsulated neuroma is reported. A 82-year-old man presented with a symptomatic skin-colored nodule on the right thumb for 10 years. Physical examination showed a well-circumscribed, skin-colored, smooth nodule,in the diameter of 0.5 cm, on the lateral right thumb. Histopathological examination showed well-circumscribed, oval or round tumors encapsulated by thick collagen fibers, located in the middle dermis. The tumors were composed of interwoven fascicles of spindle cells with elongated slender nuclei. Immunohistochemical staining revealed that the tumor cells were positive for S-100 protein, while the perineurial cells were positive for EMA. The diagnosis of palisaded encapsulated neuroma was made.
