Abstract:
Schwannoma is a benign neoplasm of the nerve sheath origin. It arises from the nerve sheath of large peripheral or cranial nerves and occurs at the level of the subcutaneous fat layer or deeper layer. Cutaneous schwannoma occurs more superficially and usually presents as a solitary dermal or subcutaneous nodule. We describe a case of cutaneous schwannoma that presented as an erythematous pedunculated protruding mass on the left flank of a 19-year-old female. It was clinically diagnosed as a granuloma pyogenicum. Shaving biopsy was conducted and histological examination revealed an encapsulated tumor mass containing dense, spindle-shaped cells whose nuclei are arranged back to back representing Verocay body, and a diagnosis of schwannoma was made. This is an unusual case of cutaneous schwannoma that presented as a pedunculated protruding mass.
