What is Transient acantholytic dermatosis and explain in detail?
Grovers disease (GD) is a polymorphic, pruritic, papulovesicular dermatosis characterized histologically by acantholysis: 529  with or without dyskeratosis.  Once confirmed, most cases of Grovers disease last six to twelve months, which is why it was originally called "transient". However it may last much longer. Nevertheless, it is not to be confused with relapsing linear acantholytic dermatosis.

Signs and symptoms
Grovers 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.  The papules are most commonly found on the mid chest.
Sometimes the features of Grovers are found in people who do not itch or have a conspicuous rash.  Most of the people with Grovers who visit a dermatologist, however, itch a lot.

Cause
The cause of Grovers disease is unknown
