Clinicopathological study of papulosquamous skin disorders in a tertiary health-care center

Background: Papulosquamous skin disorder is a group of heterogenous dermatoses with a distinct histomorphological feature. The characteristic primary lesion is a papule, usually erythematous, that has a variable amount of scaling on the surface. The most common papulosquamous dermatoses are psoriasis, lichen planus, and pityriasis rosea. Because all papulosquamous disorders are characterized by scaling papules, clinical confusion may result during their diagnosis. Our study is to evaluate histomorphological findings in various papulosquamous skin disorders encountered at RIMS, Imphal. Materials and Methods: Skin biopsies of clinically diagnosed papulosquamous skin disorders along with their relevant clinical data received during a period of 2 years from September 2017 to August 2019 were included in the study. The diagnosis was confirmed by histopathological examination using hematoxylin and eosin stain. Results: A total of 115 papulosquamous skin disorders were studied with 75 cases of psoriasis (11–80 years), 36 cases of lichen planus (2–70 years), and 4 cases of pityriasis rosea. Age ranges from 2 to 80 years. Maximum cases were seen in the age group of 31–50 (70.6%) with a mean age of 39.18 years. Both genders were almost equally affected with a male: female ratio of 1.13:1. An analysis of the clinical with histopathological diagnosis of these papulosquamous skin lesions revealed a positive correlation in 76 (66.08%) cases and a negative correlation in 39 (2.9%) cases. Conclusion: Because of the varied clinical presentation and histopathological patterns of papulosquamous skin disorder, it is important to characterize the types of papulosquamous lesions as far as possible for definitive treatment.
