Scientific articles and newer editions of medical text books show significant misapprehension among authors and scientific fraternities over the correct nosology for diagnosing and reporting vascular anomalies/malformations. This perplex have led to indiscriminate, inappropriate, and interchangeable use of terminologies while describing these vascular lesions, often resulting in incorrect diagnosis, unwarranted investigations, and improper treatment. It is often impossible to determine clinically and histopathologically whether the vascular lesion is a malformation or a neoplasm, with more than 50% of the vascular anomalies being diagnosed and termed incorrectly as hemangioma. With the help of three case reports of simple vascular malformations, each afflicting the capillaries, veins and lymphatics, we attempt to guide the clinicians in adhering to the International Society for the Study of Vascular Anomalies (ISSVA) classification. We anticipate that this case report shall be the framework that helps clinicians and pathologists to avoid misdiagnosis and misreporting of vascular malformations.

Renal hemangioma is a rare tumor which can be capillary or cavernous. There have been less than 30 renal capillary hemangioma cases reported in the English literature. Herein we will report a case of renal hemangioma which was detected in a 74-year-old man operated with the impression of urothelial carcinoma of hilum. Article Info

Vascular tumors of infancy and childhood represent a number of clinicopathologically distinct entities for which precise histopathological diagnosis is often essential in determining effective therapeutic approach. Unfortunately, pathologists and clinicians alike have traditionally tended to lump these tumors, in addition to small vessel vascular malformations, under overly generic terms like capillary hemangioma that do little, if anything, to guide proper clinical management. In the last decade this nosologic oversimplification has begun to wane as important new diagnostic tools and better understanding of etiology have evolved, facilitated by international recognition of the need for a multidisciplinary approach in dealing with these perplexing and often clinically devastating lesions. This article provides a brief historical perspective on this progress, and then focuses on the current clinical, histological, and immunophenotypical features that distinguish the major types of vascular tumors of infancy and childhood, also reviewing new evidence regarding their mechanisms of pathogenesis.
