Benign solitary keratosis with hypergranulotic dyscornification.

The most distinctive histopathologic finding is the presence of a prominent granular layer with clumped perinuclear keratohyaline granules. Some cases had mounds of rounded, anucleate glassy eosinophilic corneocytes in the stratum corneum.
