Pleomorphic Hyalinizing Angiectatic Tumour: A Rare Case Report and Discussion of Differential Diagnosis
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 8
Abstract
Pleomorphic Hyalinizing Angiectatic Tumour (PHAT) is one of the rare soft tissue tumour which is non-metastasizing. The origin of this tumour is yet uncertain. It occurs in adults as a slow growing subcutaneous mass mimicking clinically and histologically to various benign and malignant soft tissue tumours such as schwannoma, haemangioma and malignant fibrous histiocytoma. The microscopic features of this tumour include clusters of ectatic, fibrin containing, hyalinized blood vessels with pleomorphic and spindle shaped tumour cells showing intranuclear inclusions, stromal haemosiderin pigment and a variable inflammatory infiltrate. Despite marked pleomorphism, the lesion behaves as a low grade neoplasm, with frequent recurrences, but no metastases. The incidence of this tumour is very rare with less than 100 cases being published. Hence, awareness of this entity is must for proper management of the patient and to avoid misdiagnosis of the lesion. We report a case of pleomorphic hyalinizing angiectatic tumour in a 50-year-old man who presented with a slow growing mass in the left calf region since two years.
