Small Plaque (Digitate) Parapsoriasis Is an 'Abortive Cutaneous T-Cell Lymphoma' and Is Not Mycosis Fungoides

Brocq3 describes three major subgroups, the common features of which are (1) the long duration of the disease; (2) no reduction of general health; (3) absence of pruritus; (4) superficial localization of the process involving the upper dermis and the epidermis, leading to erythema and pityriasiform scaling; (5) resistance to topical treatment modalities; and (6) histologically round cellular infiltrate around dilated blood vessels of the papillary dermis, edema References 1.

Abstract ABOUT 100 YEARS ago, Unna et al1 described two cases of so-called parakeratosis variegata. Brocq,2 7 years later, saw one of Unna and colleagues' cases, as well as some similar cases, and described it as ''érythrodermies pityriasiques en plaques disséminées.'' In a 1902 article, Brocq3 reviewed the German, French, and American literature and reported 10 cases of his own, for which he created the term parapsoriasis because of their similarities to psoriasis, seborrheic eczema, and lichen (''paralichen''3). Brocq3 describes three major subgroups, the common features of which are (1) the long duration of the disease; (2) no reduction of general health; (3) absence of pruritus; (4) superficial localization of the process involving the upper dermis and the epidermis, leading to erythema and pityriasiform scaling; (5) resistance to topical treatment modalities; and (6) histologically round cellular infiltrate around dilated blood vessels of the papillary dermis, edema References 1.
