Trichilemmal cysts are benign cutaneous tumors that originate from the outer root sheath of hair follicle and frequently affect middle-aged females. These are mostly found on the scalp and rarely involve the face, neck and trunk. A 30-year-old male visited our clinic for skin-colored, tender, subcutaneous nodule on the 5th toe of his right foot without any history of trauma. A complete excision of the tumor was performed. Histopathological examination revealed a trichilemmal cyst that is lined by a stratified squamous epithelium composed of swollen pale keratinocytes, without the formation of a granular layer. Only few cases have been reported to occur on locations with no hair follicles. This case describes a trichilemmal cyst on the toe, which is an unusual location for these tumors.
