Grover's disease (GD), also known as benign papular acantholytic dermatosis,[1] transient acantholytic dermatosis,[1] and persistent acantholytic dermatosis[1] is a polymorphic, pruritic, papulovesicular dermatosis characterized histologically by acantholysis[2]:529 with or without dyskeratosis.[3] Once confirmed, most cases of Grover's disease last six to twelve months, which is why it was originally called "transient". Unfortunately it may last much longer. Nevertheless, it is not to be confused with relapsing linear acantholytic dermatosis.

Symptoms[edit]

Advanced case, third month
Advanced case, fifth month

Grover's disease often starts quite suddenly. There are intensely itchy spots on the central back, mid chest and occasionally elsewhere. Frequently, it follows sweating or some unexpected heat stress.

The itchy eruption lasts an average of 10–12 months. It is characterized by papules and papulovesicles with excoriations occurring on the chest, back, lower sternum, arms, and thighs.[4] The papules are most commonly found on the mid chest.

Sometimes the features of Grover's are found in people who do not itch or have a conspicuous rash. Most of the people with Grover's who visit a dermatologist, however, itch a lot.

Epidemiology[edit]

The prevalence and incidence of Grover's disease have not been firmly established. In a study from Switzerland, Grover's disease was diagnosed in just 24 of more than 30,000 skin biopsies [4]. Grover's disease is mainly seen in males over the age of forty.[5]

Grover's disease affects chiefly white adults in the fifth decade or later, and appears to be around 1.6 to 2.1 times more common in men than in women. Grover's disease appears less commonly in darker-skinned individuals.[citation needed] [6]

Etiology[edit]

The etiology of Grover's disease is unknown. Suspected triggers of disease activity include heat and sweating, sunlight, and adverse reaction to medications[7]:24 as well as ionizing irradiation, end-stage renal disease/hemodialysis, and mechanical irritation or prolonged bed rest.

Some cases of Grover's disease have been associated with medications such as sulfadoxine-pyrimethamine, ribavirin, cetuximab, and interleukin-4 [1,8-15]. One series of 300 patients with Grover's disease reported an association with other coexisting dermatoses including atopic dermatitis, contact dermatitis, and xerosis cutis. Finally, smaller series have detailed an association with pyoderma gangrenosum, bacterial and viral infections, and occasionally, malignancies.[6]

Diagnosis[edit]

Grover's may be suspected by its appearance, but since it has such a characteristic appearance under the microscope a shave skin or punch biopsy is often performed.

Treatment[edit]

The most important thing about Grover's disease treatment is to remain cool, as further sweating will induce more itchy spots. However, lesions aggravated by sweat usually return to "normal" fairly quickly—avoiding sweat is not a reason to avoid exercise. Minor outbreaks can be controlled with prescription strength topical cortisone creams. More troubling eruptions usually clear up after treatment for one to three months with Accutane or tetracycline. If these fail or the outbreak is severe, PUVA phototherapy treatments, antifungal pills and cortisone injections are alternatives.[8]

A further treatment option is a cream of zinc oxide, talc, and glycerol. This cream helps with the itching and promotes faster healing. In France, where it is available over the counter (OTC), the zinc oxide, talc, and glycerol cream is branded as Aloplastine.[citation needed]

Although the cause of Grover's is unknown, it may arise in quite dry skin. Many affected individuals are sun damaged.[citation needed]

Some research has suggested a correlation of Grover's disease with mercury toxicity[9] in which Chemet may help.[10]
