Lymphovascular Malformation - A Report of Two Cases

Congenital Vascular Malformations (CVM) represents a group of vascular anomalies that are the result of defective development of the vascular system. Lymphatic malformation consists of dilated lymphatic vessels caused by occlusion of the lymphatic drainage system due to congenital malformations or acquired causes such as the effects of trauma, infection, or surgery. Lymphaticovenous Malformation (LVM) is composed of lymphatic and venous channels. The most common sites are the neck and axilla. We report two cases of a four and a half-year-old and a seven-year-old child who presented with complaints of swelling in arm and groin respectively. A provisional diagnosis was made on radiological investigations. Excision was done and the diagnosis was confirmed on histopathology and immunohistochemistry. The cases which were presented as LVMs are rare congenital tumours and require a high index of suspicion on part of pathologist and surgeon to reach a definitive diagnosis.
