Acquired bilateral telangiectatic macules (ABTM) is a benign red-brown darkening of the skin on the upper arms of adults. Its cause is unknown, but some have theorized it is related to chronic sun exposure.


A report describes 13 patients with multiple telangiectatic pigmented macules on the upper arms. The mean age in the study was 43 years. Most were men. All patients had Fitzpatrick skin types III or IV [JAMA Derm 2014;150;974].


No treatment is needed. Moderate improvement was achieved with the IPL (intense pulsed light).
