Abstract

Malignat proliferating trichilemmal tumor (MPTT) are rare tumors usually presenting in photo-exposed areas, especially on the face, scalp, neck,and dorsal part of the hand. Differential diagnosis include squamous cell carcinoma, basal-cell carcinoma, keratoacanthoma and malignant nodular melanoma, so that only incisional biopsy can lead to pre-operative diagnosis. We present case MPTT misdiagnosed with parotid gland malignant tumor that underwent radical surgical excision and adijuvant radiotherapy.
