HæMANGIOMA OF BLADDER IN CHILDREN AND YOUNG ADULTS

Abstract

SUMMARY AND CONCLUSIONS A case is reported of hamangioma of bladder occurring in a boy aged 4 years. The nature and treatment of this lesion as it affects young people is reviewed with an analysis of 31 cases previously reported in the first two decades of life. The following points emerge: Hzmangioma of bladder usually presents with recurrent episodes of hzmaturia which may be associated with anamia. Hamangiomatous lesions elsewhere on the body have been described in 31 per cent. of the cases reported to date. Some abnormality of the bladder outline in the intravenous pjelogram was noted in only 50 per cent. of cases in which this investigation was done. Although there is some disagreement. it is generally considered that biopsy should be avoided for fear of provoking troublesome bleeding. In two‐thirds of the reported cases the lesion has been solitary and well defined, usually involving the upper half of the bladder. It is exceptional for these lesions to involve the ureteric orifices or bladder neck. Hamangiomata may achieve great size, and 64 per cent. involved the muscular layers of the bladder wall, many of which extended into the perivesical tissue. Cavernous haemangioma is the most common histological type. Partial cystectomy appears to be the most safe and effective method of treatment.
