Histologic analysis revealed a filiform projection of compact orthohyperkeratosis forming a thin, hornlike structure. The underlying epidermis was mildly acanthotic and devoid of dysplasia. Mild hypergranulosis was noted as was subtle perivascular lymphocytic infiltrate (Figure 2). The features were consistent with multiple minute digitate hyperkeratosis. The patient applied 12% ammonium lactate lotion twice a day to the affected areas resulting in significant flattening of the lesions.
