Answer

The transient acantholytic dermatosis (Grover disease) process usually begins as an eruption of the skin on the anterior part of the chest, the upper part of the back, and the lower part of the rib cage (see the images below). [11]

Patients who are severely affected may have disseminated disease affecting the neck, the shoulders, the arms, and the legs. The scalp is usually not affected, and the palms and the soles are almost always spared.

Individual lesions are erythematous to red brown keratotic papules that remain discrete and do not usually tend to coalesce. Occasionally, lesions may be acneiform, vesicular, pustular, and rarely even bullous. Although the most common presentation is that of widespread scattered papules, unusual distributions, including zosteriform or unilateral, may occur. [12]

The utility of dermoscopy is limited, as no features specific for transient acantholytic dermatosis have been reported.
