case_images: Clinical, dermoscopic, and histological images. (A and C) Physical examination showed the facial redness and flushing also erythematous-brownish macules and patches were widely distributed in his back area, with a few telangiectasias. (B and D) Dermoscopy imaging demonstrated the branching linear vessels of the facial lesion area and the branching linear vessels in a reticular pattern with a brown pigmentation network of the back area. (E, F, G and H) Telangiectasia in the upper dermis with perivascular mononuclear cells infiltration (Hematoxylin and Eosin-staining, original magnification x40, x200), displays the presence of mast cells (Toluidine-staining, original magnification x40, x200).

case_images: Upon physical examination, facial redness and flushing were shown, in addition to the facial area, the erythematous-brownish macules and patches were widely distributed in the trunk and limbs with a few telangiectasias found unexpectedly although the patient did not describe it (Figure 1A and C). Dermoscopy imaging demonstrated the branching linear vessels of the facial lesion area and the branching linear vessels in a reticular pattern with a brown pigmentation network of the back area (Figure 1B and D). Toluidine staining display the presence of mast cells (Figure 1E-H; Hematoxylin and Eosin-staining, Toluidine-staining, original magnification x200). The clinical, dermoscopic, and histological findings were consistent with a diagnosis of telangiectasia macularis eruptiva perstans (TMEP).
