nodThis patient has most likely hereditary telangiectasia, characterized by diffuse telangiectasias, recurrent epistaxis, and widespread AV malformations(AVMs) that in the lungs can shunt blood from the R to the L side of the heart causing chronic hypoxemia and a reactive polycythemia.

if it werent for the lips, I would also have chosen polycytemia
