Epidermoid Cyst : A Clinicopathological Study In A Real World Clinical Setting

Background : Epidermoid cysts, sometimes called epidermal inclusion cysts or epidermal cysts, are a kind of benign intradermal or subcutaneous tumour that are commonly found on the head, face, neck, trunk, and limbs. They are quite common. A typical kind of cutaneous cyst with an epidermis-like epithelial lining (wall) is called an epidermoid cyst. An outcome of proliferation of surface epidermoid cells within the dermis. Methodology : This is a retrospective cross-sectional observational study carried out over a period of 3 years conducted at Chettinad Hospital and Research Institute. The total samples obtained were 926 and the specimens were chosen randomly until the gathered samples were adequate as per sample size and from those patients who are willing to consent for taking part in the study. Histological examination and clinical data were collected Results : A total of hundred cases were examined and the common diagnosis was found to be epidermal cyst in 78.9% of instances, with trichilemmal cysts following in 8.9% of cases. Steatocystoma and vellus hair cysts were uncommon varieties. One instance had proliferating trichilemmal cysts, whereas two cases had proliferating epidermal cysts. There were no incidence of any malignancy among the selected samples. Conclusion: Epidermal cysts were found to be most common among the soft tissue swellings that were isolated in the institute and was followed by trichilemmal cysts. Since no malignant change was noted in the samples we can conclude there are very less chances of any malignant transformation to occur in epidermoid cysts.
