A Case of Phakomatosis Pigmentovascularis Type I a With Multiple Pyogenic Granulomas Developed in Pregnancy / 대한피부과학회지

Phakomatosis pigmentovascularis(PPV) was first described in 1947 as a distinctive association of vascular and pigmentary nevi by Ota et al. Hasegawa et al subclassified the disorder into eight types and type I a is characterized by the coexistence of nevus flammeus and nevus pigmentosus et verrucous, which is not associated with systemic organ involvement. PPV type I a is relatively rare and a case with multiple pyogenic granulomas developed in pregnancy, is not reported yet. We present a case of PPV type I a with multiple pyogenic granulomas developed in pregnancy within nevus flammeus in a 29-year-old female.
