BACKGROUND Papulosquamous lesions form the largest group of skin diseases. Since, they are all characterized by scaling papules or plaques, clinical confusion may result in their diagnosis, hence definitive histopathological analysis is important for their differentiation. MATERIALS AND METHODS The study includes skin biopsies from 108 clinically diagnosed /suspected non-infectious, erythematous, papulosquamous skin diseases which were received in the Department of Pathology, Andhra Medical College, Visakhapatnam for a period of two years from January 2016 to December 2017. The specimens obtained were subjected to formalin fixation and was subjected to routine processing and sections were stained with haematoxylin and eosin (H&E). The lesions were classified as Lichen Planus, Psoriasis, along with rare conditions like Pityriasis Rosea, Parapsoriasis, Pityriasis Rubra Pilaris, Prurigo Nodularis and Lichen Simplex chronicus and clinicopathological correlation was done. RESULTS A total of 108 cases were studied. Lichen planus (51 cases- 47.22%) was the most common lesions followed by Psoriasis (34 cases - 31.48%) and with majority of cases in the age group of 21 to 30 years (25 cases– 23.15%). Females were more commonly affected with a male to female ratio of 0.89:1. Out of 108 cases, clinicopathological correlation was seen in 68 cases (62.96%). CONCLUSION The importance of specific histopathological diagnosis lies in distinguishing these lesions into different entities as the treatment and prognosis varies widely and is disease-specific.
