Transient acantholytic dermatosis
Clinically, transient acantholytic dermatosis presents with red scaly papules and papulovesicles over the trunk. The condition is usually intensely pruritic; however, some patients are completely asymptomatic. Flares of disease may be marked by an increase in both pruritus and surrounding erythema, vesicles, and erosions. This appearance is frequently encountered on the backs of hospitalized patients on prolonged bed rest.
This condition is histologically variable, and the key finding on pathology is focal acantholysis. The disease can be self-resolving or may wax and wane for several years. Since the condition is benign, the primary goal of treatment is control of symptoms.
