GROVER'S DISEASE

Grover'’s disease is a type of "heat rash" associated with increased sweating that occurs most often during periods of head, sweating or hospitalization. It seems to be a type of eczema aggravated by sweat sitting on the skin.

• Women may develop it at menopause as a result of hot flashes.
  
• One study showed it to be commonly associated with hospitalized patients on strict bed rest with abundant sweating.
  
• In the past, it was thought to be associated with malignancy, but this is not true.
• Although also called transient acantholytic dermatosis, some cases are not transient.
  
• Asteatotic eczema occurs five times as often month patients with GD as controls.
• Ask if they do "hot yoga"!

Discrete, pruritic, crusted papules and papulovesicles in a middle-aged or elderly person is characteristic. The rash is usually symmetric across the lower chest with an increased involvement just below the breasts in both men and women. Though usually transient (weeks to months), the disease may last years. A TAD-like rash has resulted from interleukin-4 administration.

Erythematous, crusted papules are typical
