Quick Answer
Grover's disease is an itchy rash of small red bumps on the chest, back and upper abdomen, mainly affecting men over 40. Heat, sweating, sun and prolonged bed rest trigger flares. It is benign and usually settles over 6–12 months. Treatment focuses on cooling measures, emollients, potent topical steroids and antihistamines, with oral retinoids or phototherapy for stubborn cases.

When to See a Doctor
See a doctor if the itch is disturbing sleep, if the rash is spreading or blistering, or if it fails to improve with topical steroids — a biopsy confirms the diagnosis.
Frequently Asked Questions
How long does Grover's disease last?
The 'transient' name is optimistic. Most cases run for six to twelve months, and some become chronic and relapsing, particularly if heat exposure continues.
Is Grover's disease contagious or related to cancer?
It is neither contagious nor a sign of cancer. It is a benign disorder of skin cell adhesion, though a biopsy is often done to confirm the diagnosis.
