Papulosquamous disorders comprise a group of dermatoses that have distinct morphologic features. The characteristic primary lesion of these disorders is a papule, usually erythematous, that has a variable amount of scaling on the surface. Plaques or patches form through coalescence of the primary lesions. Some common papulosquamous dermatoses are pityriasis rosea, lichen planus, seborrheic dermatitis, tinea corporis, pityriasis rubra pilaris, psoriasis, and parapsoriasis. The etiology, diagnosis, and treatment of pityriasis rosea, lichen planus, and seborrheic dermatitis (including seborrheic dermatitis associated with AIDS) are discussed in this chapter. Also discussed are the diagnosis and treatment of pityriasis rubra, parapsoriasis (pityriasis lichenoides and small- and large-plaque parapsoriasis), and erythroderma. This chapter includes color photographs of the aforementioned dermatoses plus the Koebner phenomenon, lichen planus of the mucous membranes, and erythroderma in Sézary syndrome. This review contains 11 highly rendered figures and 79 references.

Background: Papulosquamous dermatoses is a complex group of disorder characterized by scaly papules and plaques. There is a need to study the exact, pattern and prevalence of this disorder in different age groups and their line of treatment. Objective of the study was to observe the clinical pattern of various papulosquamous dermatoses and their prevalence at tertiary care center, Ujjain.Methods: This was an observational study done in R.D. Gardi Medical college, Ujjain over a period of one year. A total of 229 cases including male and female of papulosquamous dermatoses were enrolled from the outpatient department. All patients were studied clinically and relevant data was recorded. Microsoft excel was used for data entry and analysis was done using SPSS version 23.Results: There were 139 (60.7%) males and 90(39.3%) females with overall male to female ratio was 1.54:1. Most common age group affected with papulosquamous dermatoses was 31-50 years. The clinical pattern observed was psoriasis 49.3%, lichen planus 24.5% followed by pityriasis rosea 10.5%. The least common papulosquamous diseases were pityriasis rubra pilaris (1.3%) and lichen nitidus (1.3%). Most common variant of psoriasis and lichen planus was chronic plaque and classical respectively. Classical juvenile variant of pityriasis rubra pilaris was seen in our study. A single rare case of lymphomatoid papulosis was noted in our study.Conclusions: Psoriasis, lichen planus and pityriasis rosea were commonest papulosquamous diseases were observed but still we need more longer duration of observational studies on papulosquamous dermatoses to understand the morphological features for the effective management of these diseases.
