Bilateral Eccrine Angiomatous Hamartoma with Symmetric Volar Wrist Nodules: A Case Report

We describe a 13-year-old girl with bilateral symmetric eccrine angiomatous hamartoma (EAH) on the volar aspect of the wrists. The lesions were painless and had been enlarging progressively for 1 year; the enlargement of the nodule on the right wrist was more substantial than that on the left wrist. She had palmar hyperhidrosis, which has a known association with EAH.

To our knowledge, bilateral symmetric EAH has been reported only 3 other times in the literature. In all 3 of these cases, the lesions were on the dorsum of the hands or the wrists. We believe that this is the first report of this rare presentation on the volar aspect of the wrist. The symmetry suggests that the lesions may be the manifestation of a systemic or mechanical cause.
