Two Cases of Telangiectasia Macularis Eruptiva Perstans / 대한피부과학회지

ABSTRACT

Telangiectasia macularis eruptiva perstans(TMEP) is an uncommon form of mastocytosis. This disorder is characterized by reddish-brown macules with telangiectases, usually involving the trunk. Due to the small number of mast cells, Darier's sign is usually absent. Histologic changes are very subtle, showing only a slight increase in mast cell numbers around capillaries and venules of the superficial plexus. We report two cases of TMEP. Their histologic alterations include dermal vascular dilatation and perivascular mast cell infiltration.
