Grover's Disease

Grover's disease is a sudden onset of red itchy bumps on the upper chest and back. Dermatologists may make the diagnosis from the appearance of the rash, but a skin biopsy may be necessary to confirm it. Grover's disease has a characteristic appearance under the microscope. It is probably caused by blocked sweat ducts and is treated with air conditioning.

Most cases of Grover's disease last six to twelve months. Occasionally it may persist for longer. Cortisone pills clear it up temporarily, but the rash returns as soon as the drug is stopped. Treatment often seems unsatisfactory. The most important thing is to remain cool, as further sweating will induce more itchy spots. A mild topical steroid such as hydrocortisone in a cool lotion can be applied frequently to the affected areas and result in relief.
