Clinical analysis of tufted angiomas in infants / 中华实用儿科临床杂志

ABSTRACT

Objective To describe and examine the clinical characteristics and spectrum of tufted angiomas (TA) in infants so as to explore the therapeutic approaches to Kasabach-Merritt phenomenon (KMP).Methods The clinical and follow-up data of 24 patients with TA were retrospectively analyzed between Jan.2009 and Mar.2013.The median age of the patients was 7.5 months(ranged from 18 days to 2 years),including l0 male and 14 female.Surgical excision and observation were chosen according to the lesion and conditions of the patients.The mean follow-up period was 3.6 years (1.2 to 5.4 years).The changes in the patients' s condition were established by evaluating platelet counts,and the size of lesion.Results Common clinical features included dusky red or violaceous infiltrating cutaneous lesion,thrombocytopenia,pain or decreased function and hyperhidrosis or hypertrichosis.The following 3 clinical patterns of TA progress were describedspontaneous complete or partial regression (n =2,8.3％),TA without complications and persistence over the years(n =9,37.5％),and TA complicated by KMP(n =13,54.2％).The average interval of development of KMP for delayed cases was 45.2 days(ranged 0 d to 4 months).Each of the 13 patients who developed KMP subsequent to initial presentation was symptomatic at the time KMP was detected(enlarged lesion,n =8;increased lesion firmness with change in cutaneous stain,n =3 ;and respiratory distress,n =2).All of 13 patients were cured by surgery.Complete surgical resections were performed on 10 cases.The thrombocyte count was back to normal within 1-3 days post operation,and hemoglobin and blood coagulation function gradually returned to normal within 1 to 2 weeks.Other 3 cases received major resection surgery.The number of platelets in the patients were unstable,but significantly higher than that of preoperational stage.The platelet count remained above 60 × 109/L.The residue lesions in 2 cases disappeared gradually after the operation and medication were given within 3-6 months.And the other case died of multiple organ failure post-operation.Conclusions Surgical intervention can be applied to TA that severely makes damage to children's appearance or looks or may be complicated with KMP or functional abnormality.A closely monitored policy seems appropriate for the early small tumor without severe complications.And it is necessary to monitor the number of the platelet regularly and find the KMP by as early as possible.TA associated with KMP is vitol to infants.And surgical therapy after clear diagnosis should be done as early as possible.The surgical therapy is a reliable management with higher curative rate,short disease period and minimal side-effect.
