Bilateral Eyebrow Sclerosis: A New Clinical Entity

Abstract

Summary:. We report a man with sparse eyebrows and recurrent bilateral subcutaneous nodules beneath the eyebrows. Their histopathologic features were sclerosis of a subcutaneous lesion. The proliferation of muscle was not obvious and inflammatory cell infiltration was inconspicuous, but some dilated capillaries were noted. Collagen was regularly interlaced, thickened, and hyalinized with dispersed fibroblasts. Various skin tumors can occur on adult faces, but this presentation, to our knowledge, was unique and could not be characterized as a known condition. Plastic surgeons, dermatologists, and pathologists may encounter similar conditions, so it should be considered as a new clinical entity called bilateral eyebrow sclerosis. This may be of comfort to patients with similar conditions. Moreover, we propose enlarged resection to include the skin surface and underlying muscles as an effective treatment for recovery of the eyebrows and prevention of recurrence.
