Hereditary Benign Telangiectasia: a Case Presentation and Review of Literature

Abstract

Hereditary benign telangiectasia is a rare condition characterized by cutaneous generalized telangiectasias and angiomas. This diagnosis should be suspected in patients with this type of lesion, with a positive family history, without bleeding or mucosal involvement. We present the case of a man aged 30 years with numerous telangiectasia and angiomas located on the face, neck, anterior and posterior thorax, and arms, without bleeding. Histopathology revealed a normal epidermis with dilated subpapilar plexus. The anamnesis revealed similar lesions in other family members. Electrocauterization or laser therapy has been proposed as a treatment for these lesions. Differential diagnosis must be done mainly with other two rare conditions: hereditary hemorrhagic telangiectasia and generalized essential telangiectasia.
