Painful, slow-growing recurrent nodules

Author and Disclosure Information

The patient’s mother and son had similar lesions. Histopathology revealed an uncommon diagnosis.



A 67-year-old woman presented with multiple painful nodules that had developed on her scalp, face, and neck over the course of 1 year. She also had a few nodules on her trunk and hip. There was no associated bleeding, ulceration, or drainage from the lesions. She had no systemic symptoms. The patient reported that she’d had a similar lesion on her frontal scalp about 15 years earlier, and it was excised completely. (She was not aware of the diagnosis.) She indicated that her mother and son had similar lesions in the past.

Her medical history was remarkable for diabetes and hypertension, which were well controlled on metformin and lisinopril, respectively. The patient had cancer of the left breast that was treated with mastectomy and chemotherapy 3 years prior.

On physical examination, the patient had multiple firm, rubbery, tender nodules with tan or pink hue, measuring 1 to 1.5 cm. The nodules were located on the left side of her chin and right preauricular area (FIGURE 1), as well as the right sides of her neck and hip. Most of the nodules were solitary; the preauricular area had 2 clustered pink lesions. The largest nodule was located on the patient’s chin and had overlying telangiectasias.
