We present the case of a 58-year-old woman who was diagnosed as having telangiectasia macularis eruptiva perstans (TMEP) and was successfully treated with PUVA photochemotherapy. During the 6-month follow-up, no recurrence of pruritus or skin lesions was observed. TMEP represents a rare form of cutaneous mastocytosis, which is clinically characterized by reddish-brown telangiectatic macules symmetrically distributed over the trunk and extremities. Although in the majority of cases the disease is limited to the skin, systemic involvement may occur. The treatment of TMEP is challenging and several therapeutic modalities have been proposed in the past.
