Desmoplastic fibroblastoma is a rare fibrous tumor that usually presents as a painless, slow-growing mass in the subcutaneous tissues and skeletal muscles. It has a wide anatomic distribution, with the most common involvement being the arm and shoulder. Here, we report a case of a tiny painful desmoplastic fibroblastoma arising on the scalp. According to a microscopic examination, this tumor was composed of spindle-shaped fibroblasts in the dense collagenous stroma. On immunohistochemical staining, tumor cells were positive for vimentin and negative for smooth muscle actin, CD34, and S100. Our case is unique in that desmoplastic fibroblastoma developed on the scalp and there was presence of pain despite its small size.

Neurilemmoma, also called schwanomma, neurinoma, and perineural fibroblastoma is a rare benign tumor originated from the schwann cell of nerve sheath. They occur commonly at 20-50 aged person and involved the head and neck and flexor surface of the extremity. Histologically, they are characterized by Antoni A and Antoni B tissue composed of high and low cellularity. Primary neurilemmoma involved in the bronchial wall is extremely rare and few cases have been reported previously. We experienced neurilemmoma of the bronchial wall in a 72 year old woman. The pulmonary radiology showed the right middle lobe collapse with single lymphadenopathy, and bronchoscopic biopsy was performed to confirm the neurilemmoma.

Neurilemmoma is a benign tumor which arises generally from the Schwann's cells. It is a slowly growing tumor and treated as surgically. We experienced a case of neurilemmoma of the oropharynx in a 28-year-old female who had noticed a gradual swelling of the left side of the oropharynx with swallowing difficulty for 6 months. The tumor was removed successfully intra-orally under the general endotracheal anesthesia and verified pathologically as neurilemmoma.
