ABSTRACT
Proliferating trichelemmal tumors (PTT) are uncommon benign tumor originating from outer root sheet of the hair follicle. The histologic hallmark is the presence of trichelemmal keratinization/ abrupt keratinization. PTT is thought to originate from the Trichelemmal cyst (TC) and have the potential for malignant transformation at which point it is termed to be Malignant Proliferating Trichelemmal Tumor (MPTT). It is usually confused with Squamous Cell Carcinoma both sharing many common features. These lesions may cause considerable morbidity and even mortality and recurrence after simple local excision in common. We hereby present a rare case of a 50 old male patient with a rapidly growing swelling of the scalp on the occipital region which was ulcerating and foul smelling discharge was present. A wide excision was done and histopathological examination revealed proliferating trichelemmal tumor which on history and gross appearance was mimicking malignant tumor.
Key words: Proliferating trichelemmal tumor, Squamous cell carcinoma, Trichelemmal cyst, Malignant proliferating trichelemmal tumor.
