Treatment for Grover’s disease generally involves controlling minor outbreaks with prescription-strength cortisone cream applied topically to the affected area, according to the American Osteopathic College of Dermatology. Prescription tetracycline or Accutane may be required for more severe outbreaks and eruption. Other alternatives include cortisone injections, antifungal medications and phototherapy treatments.
Grover’s disease, which is medically known as transient acantholytic dermatosis, is characterized by a sudden onset of itchy red spots that are concentrated on the trunk of the body, notes the AOCD. Older men are usually the most affected. Not all sufferers of Grover’s disease itch or develop the characteristic conspicuous rash; some people may not itch at all.
A shave skin biopsy is used to make a definitive diagnosis of Grover’s disease, according to the AOCD. The condition generally lasts for 6 to 12 months following its onset, although it can last much longer in some individuals. The itching of those affected by Grover’s disease is what generally causes them to seek out treatment with a dermatologist.
The exact cause of Grover’s disease is not known, as of 2015. Often, the disease seems to begin or worsen after the sufferer has been exposed to temperature extremes, although this is not always the case. Sometimes it appears on its own without warning, notes the AOCD.
