Skin and mucosal telangiectatic lesions in hereditary hemorrhagic telangiectasia patients.

The typical round, flat telangiectatic lesion is the most common lesion in HHT, but it is very often accompanied by elevated or elongated lesions. The total number of lesions did not vary between gender, but women had significantly more lesions in the mucosa (p = 0.027). The presentation of telangiectatic lesions may vary a little between HHT1 and HHT2 patients but not in such a way that allows the morphology and location of the lesions to predict the HHT subtype.
