MESENTERIC MIXED HEMANGIOMA AND LYMPHANGIOMA - REPORT OF A CASE WITH 10-YEAR FOLLOW-UP AFTER RADIATION TREATMENT

A patient with massive mixed haemangioma and lymphangioma of the mesen tery first presented in childhood with ascites which subsided spontane ously and, subsequently, at 21 years of age, presented with gastrointe stinal bleeding. At laparotomy, the lesion was found to involve 90% of the mesentery and was unresectable due to its bulk. Hence he was trea ted by radiotherapy (15 Gy/15 fractions/3 weeks followed by a boost of 5 Gy/4 fractions/4 days). He responded to the treatment. 10 years lat er he again experienced mild gastrointestinal bleeding which subsided spontaneously. This case illustrates the efficacy of radiotherapy in m assive mesenteric haemolymphangiomas. Review of the literature reveale d that surgical excision, embolization, and radiotherapy have been use d in the treatment of haemangiomas and lymphangiomas. In unresectable cases, radiotherapy has a definite role in the management. A variety o f doses has been employed in the literature. No definite dose-response relationship was identified.
