Histomorphological Study of Skin Lesions in a Specialized Tertiary Care Hospital: A Descriptive Study

Abstract

Introduction: The skin is the largest organ of the integumentary system in human. Dermatological lesions are commonly encountered in all countries and it encompasses a wide spectrum, varies from country to country and various regions within a country. Skin diseases are much common in developing countries. The spectrum varies according to geographic distribution, gender, age, and coexisting disorder. We conducted this study to find out the prevalence of different skin lesions and to evaluate their frequency and site of distribution. Aim of the Study: The aim of this study was to find out the prevalence of different skin lesions and to evaluate their frequency and site of distribution. Methods: This was a descriptive study and was conducted in the Department of Histopathology of Bangladesh Specialized Hospital, Dhaka, Bangladesh during the period from January 2019 to December 2021.We included 133 skin biopsies in our study. Result: Among 133 skin biopsies examined, non-infectious vesicobullous and vesicopustular disease were found in 53 (48.18%) cases followed by microbial disease in 20 (18.18%) and non-infectious erythematous papular and squamous disease in 28 (21.05%) cases. Lichen simplex chronicus was the most common vesicobullous disease seen in 08 (15.09%) cases. Dermatophytes were the commonest microbial disease found in 10 (50%) cases. The commonest non- infectious erythematous papular and squamous disease was lichen planus and psoriasis 08 (15.09%) cases. The commonest neoplastic lesion was keratinocytic tumor seen in 13 (56.53%) cases. The commonest tumor of the skin was seborrheic keratosis and squamous cell carcinoma in 13 (56.53 %) cases. Upper extremities were the most frequently involved site by skin lesions. Conclusion: In our study prevalence of lichen simplex chronicus was higher. We observed a wide spectrum of skin lesions ranging from dermatitis to malignant neoplasm. The importance of specific histomorphological features lies in distinguishing various skin lesions and play a major role in making the final diagnosis of these diverse skin lesions. This highlights the role of histopathological examination for the proper management of patient.
