Skin biopsies were obtained before and after PUVA therapy from five psoriatic patients and epidermal melanocytes surveyed for the presence of intranuclear melanosome-like bodies and nuclear bodies. Intranuclear melanosome-like bodies were observed after PUVA therapy whereas none were found before therapy. Nuclear bodies were found to increase in frequency after PUVA therapy. Remnants of a nuclear envelope membrane were not found around the intranuclear melanosome-like bodies. Nor were remnants of a nuclear envelope membrane found in or around the nuclear bodies. The results are discussed in view of the possible sites of origin of intranuclear melanosome-like bodies and nuclear bodies. © 1983 Academic Press, Inc.
