A Rare Cutaneous Adnexal Tumour with a Rare Presentation
Journal Title: Journal of Krishna Institute of Medical Sciences University - Year 2016, Vol 5, Issue 2
Abstract
Proliferating Trichilemmal Tumour (PTT) is a rapidly growing large cutaneous adnexal neoplasm. Although biologically considered as benign, it may be locally aggressive. Malignant transformation of these lesions, known as Malignant Proliferating Trichilemmal Tumour (MPTT) has rarely been reported. So far in the literature, only 39 well-documented cases of MPTT have been reported. MPTT has been stated to be a neoplasm of the older age group according to review of the literature. We present a case of MPTT in a young male. A 25 year old male presented with a scalp swelling of 2 years duration with a recent rapid enlargement. The swelling was excised and histopathological examination of the excised specimen revealed features of MPTT. The differential diagnosis of MPTTis squamous cell carcinoma as both share common features. Accurate diagnosis of MPTT is essential since it has a tendency to metastasize and recur more frequently than squamous cell carcinoma.
