Occult Syringomas of Scalp Associated with Progressive Hair Loss

This report from 1980 described a case of a 57-year-old woman who experienced a progressive diffuse loss of scalp hair over 22 years, despite having previously luxuriant hair and being in good health. The study suggested that clinically inapparent tumors of the sweat gland, known as syringomas, might have been associated with her hair loss. Despite normal physical examinations and laboratory results, including tests for zinc, iron, and thyroid hormones, the hair loss persisted. Trials with low-dose dexamethasone, liothyronine sodium, and zinc sulfate were conducted, but the document did not specify their outcomes. The study highlighted the potential link between sweat gland tumors and hair loss.
