Presentation

History

One of the hallmarks of transient acantholytic dermatosis (Grover disease) is pruritus, and all individuals who are affected experience variable degrees of itching, sometimes severe in nature.

The clinical appearance does not always correlate to the degree of pruritus; for example, some patients with limited cutaneous disease complain of severe itching, whereas others with many lesions have few or no symptoms.

While lesions may resolve over weeks to months, they commonly recur.

No systemic symptoms are associated with transient acantholytic dermatosis (Grover disease), but oral lesions can develop that resemble aphthae and may be slightly painful. [8]

Physical Examination

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). [9]

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. [10]

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

Complications

Lesions may resolve with postinflammatory pigmentary alteration or with no residual change. Scarring is usually minimal unless induced by excoriation.
