Osteomyelitis after exchange transfusion.

mobile mass is often palpable, but diagnosis is usually made at laparotomy. Other clinical features and radiology are nonspecific. Cysts have been treated by aspiration and marsupialization. Cavernous lymphangiomata necessitate resection, together with the bowel if the blood supply is prejudiced by the tumour or subsequent dissection. Only one cavemous lymphangioma has been reported in the British literature (Walker and Cooper, 1959), but this was not chylous. Blecher (1966) reported the case of a 33-year-old patient with a cavemous chylangioma of the ileocaecal region, and his paper briefly reviews the subject. I wish to thank Mr. A. P. Wyatt for help in preparing this case report, Dr. I. Williams for assistance with the pathological report and photomicrographs, Dr. P. Ewan for Fig. 1, and Mr. R. Leng for photographic help.
