E-mail: [email protected] A 13-year-old girl and her little sister were born with bluish nodular cutaneous vascular lesions, respectively, on lower back and thigh (Fig. 1). The lesions became more visible as they got older and a few new lesions developed over time. No mucosal le- sions were found. Recently the lesions became tender by touch, why a dermatologist was consulted. 
It was revealed, that the father and grandfather of the girls had similar lesions. What is the likely diagnosis? Fig. 1. Bluish nodular cutaneous vascular lesions. Forum for Nord Derm Ven 2019, Vol. 24, No. 1 31
