The Interposed Smudge-Kaposiform Haemangioendothelioma

Abstract

Kaposiform hemangioendothelioma emerges as an exceptionally discerned endothelial cell neoplasm. Commonly, tumefaction disseminates within entire dermis with expansion into the subcutaneous tissue and exhibits localized tumour aggressiveness. Characteristically, proliferation of spindle shaped endothelial cells is commingled with lymphatic vessels demonstrating capillary haemangioma-like articulations. Glomeruloid structures are configured of discrete capillary lobules demonstrating a swirling pattern. Nodules of spindle shaped endothelial cells are encompassed by peripheral lymphatic vessels articulating lymphangioma-like areas. Tufted angioma configures as a benign, superficial, vascular neoplasm arising as a congenital lesion or appears within infants and paediatric population. The aggressive neoplasm is associated with enhanced morbidity and may undergo spontaneous retrogression, in contrast to Kaposiform hemangioendothelioma.
