Abstract (2. Language):
Proliferating Trichilemmal tumour (PTT) is a tumour arising from the head and neck region of elderly women. It was
first described in 1966 by Wilson and Jones as 'proliferating epidermoid cyst'. It is a benign tumour that appears as a malignant
tumour but histologically more often turns to be benign. Worldwide very few malignant PTT have been reported. It is a
tumour which is often proved benign after histopathological exam. Features of malignant tumour include non‐scalp locations, size
>5 cm, recent rapid increase in size, infiltrative growth pattern on histology, palpable lymph nodes, fixity to deeper structures.
