Abstract
Background

Grover disease is an acantholytic disorder that typically occurs on the trunk of older individuals, primarily white men, in association with heat and xerosis. Cases with extensive and/or atypical distributions have been reported.

Objective

To review the literature characterizing the population, morphology, associations, and disease course of extensive or atypical eruptions of Grover disease.

Methods

A systematic literature review identified 50 articles with 69 cases.

Results

Patient age ranged from 14 to 83 years (mean age, 56 ± 15), with 71% of patients being male and 29% female. Areas of involvement included the trunk (90%), upper and lower extremities (63% and 61%, respectively), face/scalp (28%), neck (21%), groin (11%), buttocks (8%), and axillae (6%). The most common associations included a history of malignancy (61%), recent chemotherapy (38%), and recent transplant (20%).

Limitations

Extensive cases with typical clinical morphology may not have been examined by biopsy or reported; thus, this review may have publication bias toward more severe or atypical presentations.

Conclusions

Greater variability exists among patients affected by extensive or atypical Grover disease than among those with typical disease. Malignancy is a common association, and there may be a role for immunosuppression in the pathogenesis of extensive or atypical Grover disease.
