The Ambivalent Mesenchyme-Pleomorphic Hyalinising Angiectatic Tumour

Abstract

Pleomorphic hyalinising angiectatic tumour (PHAT) is an infrequently discerned, soft tissue, mesenchymal, spindle-shaped cellular neoplasm of uncertain cellular lineage initially scripted by Smith et al in 1996 and is contemplated as a neoplasm of intermediate malignant potential [1]. The exceptional, mesenchymal lesion is frequently cogitated within subcutaneous tissue and is composed of pleomorphic, spindle-shaped cells and ectatic blood vessels encompassed by hyalinised stroma and lack of mitosis [1,2].
