Abstract:
We examined histopathologic data from 50 patients with 53 lesions of solar keratosis encountered over the past 15 years (1977 to 1991). The epidermis showed acanthosis, uneven epidermal dyeing properties, disorderly arrangement of the basal cells, atypia of the nucleus, mitotic figures and hyperpigmentation of the basal layers. The dermis showed actinic elastosis, cell infiltration mainly consisting of the lymphoid cells, and incontinentia pigmenti histologica. Among histologic types, the hypertrophic type was the primary example.
