Sacral medial telangiectatic vascular nevus: a study of 43 children.

BACKGROUND: Medial telangiectatic vascular nevi are capillary vascular malformations frequently observed at birth occurring mostly on the face or on the nape as a single lesion or as multiple macules affecting more than one site simultaneously. In 1990, Metzker and Shamir reported a medial telangiectatic vascular nevus (MTVN) in the sacral region along the midline and called this particular variety of MTVN 'butterfly-shaped mark'. OBJECTIVE: Our study was performed to investigate the morphology and localization of an MTVN in the sacral region (sMTVN) in a group of Caucasian children. METHODS: We observed 43 children with sMTVN, ranging in age from 1 month to 12 years (mean 8 years), for a period of 6 years. RESULTS: sMTVN was found as a red-violet macular lesion of rhomboid or triangular shape in 16 patients and as a group of little red-violet macules in 10 patients. In 16 patients moreover the whole back was involved with many small red-violet spots on and around the spinal column, and in 1 patient with classic sMTVN satellite macules were also present over both buttocks. Four patients suffered from epilepsy with mental deficiency. In 6 patients, the family history showed sMTVN in one or more members of the family. No case presented an association with spina bifida. CONCLUSION: In our study, sMTVN shows a morphological polymorphism while Metzker and Shamir reported the same clinical aspect in all 25 of their patients. In accordance with these authors, we noted that sMTVN persist into childhood and adult life in the same way as occipital MTVN.[1]
