HORNY PERIFOLLICULAR MUCINOSIS - AN ATYPICAL PITYRIASIS-RUBRA PILARIS-LIKE ERUPTION ASSOCIATED WITH HIV-INFECTION

We present a case of pityriasis rubra pilaris (PRP)-like eruption, in association with human immunodeficiency virus (HIV) infection, clinica lly characterized by follicular papules with some elongated spines and comedo-like lesions. The lesions were located on the back, flanks, an d proximal extremities. Orthokeratotic follicular plugs and perifollic ular mucinous degeneration were consistently observed on three biopsie s. The most characteristic histological features of PRP were absent. T o our knowledge, this is the first reported case of this kind. Such a case could suggest an atypical PRP modified by HIV infection. It is al so possible that it represents a new entity associated with advanced H IV infection (horny perifollicular mucinosis).
