Ichthyosis and alopecia after maprotiline: corneolysis caused by temporary disorder of keratinization
Niederauer HH, Bacharach-Buhles M, Altmeyer P.
A 37-year-old woman developed ichthyosiform desquamation of the skin and a severe diffuse alopoecia 3 weeks after taking the antidepressant maprotilin. No signs of inflammation were present. Histology revealed acanthosis with preserved stratum granulosum, follicular hyperkeratosis and dystrophic changes of the hair follicle. Electron microscopy revealed rarefication of tonofilaments and necrobiotic changes of epidermal keratinocytes with vacuolar degeneration of the cytoplasm and disorganization of the organelles. Pathogenetically this disease represents a drug-induced transitory disorder to keratinization, which had resulted in desquamation of the stratum corneum and <a href=”http://www.drproctor.com”>hair loss</a>. The authors propose the designation corneolysis for this pathogenetic principle.
