AbstractBackground: The papulosquamous disorders are complex to diagnose, because of the difficulty in identification and may resemble a similar disorder of the group. Lichen planus is an inflammatory dermal condition of the muco-cutaneous surfaces which present with a varied clinical manifestations. High prevalence of disease noted on the Indian subcontinent. Aim: To study the clinical & histopathological presentation of papulosquamous disorders with special emphasis on Lichen Planus. Material and Methods: Descriptive histopathological study of papulosquamous disorders of skin was conducted at Department of Pathology with 61 cases of clinically diagnosed papulosquamous eruptions. Results: Lichen planus was the commonest (57.37%) followed by Psoriasis and Prurigo nodularis. High predominance was observed in males for all diseases. Lichen planus occurred in all age groups but was commonly seen in young and middle age groups. Flat topped papules and plaques were the commonest type of clinical patterns seen in Lichen planus. Out of 35 cases of Lichen planus, 29 were clinically diagnosed and confirmed by histopathology. Conclusion: Clinical diagnosis was difficult due to overlapping of both clinical pattern and distribution of papulosquamous skin disorders. Combination of proper clinical observation, histo-pathological & morphological study for conclusive diagnosis.
