TELANGIECTASIA MACULARIS ERUPTIVA PERSTANS

Telangiectasia macularis eruptiva perstans (TMEP) is a variant of mastocytosis in which telangiectatic macules are the presenting sign. They often occur on the trunk of a woman. Special stains may be needed to help identify the mast cells histologically.

Clinical

Clinically, one sees 5-10 mm pink/brown telangiectatic macules, predominantly on the trunk. Itching may vary from mild to intense. Gentle scratching may elicit the Darier sign.

Workup

Workup should include a CBC and tryptase to assess for systemic involvement. Any abnormality should prompt a referral to Hematology/Oncology.
