ABSTRACT:The term sebaceous cyst is a term which denotes the subcutaneous cyst occurring due to obstruction of pilosebaceous ductal opening. The swelling is asymptomatic soft and cystic and fluctuant when not infected. The cyst is usually lined by an epithelium and filled with keratin, may also contain dermal appendages from the cystic wall. Histologically this cyst is considered to be an Epithelial cyst. The types of Epithelial cyst are Epidermoid cysts, pillar cysts, Dermoid cyst and steatocystoma. When the cystic lining contain only epidermis cyst is called as epidermoid cyst and when the cyst contain multiple dermal adnexea from the cystic wall, the cyst is called Dermoid cyst. The pillar cyst consist of epithelial lining without granular cell layer resembling the follicular epithelium containing mixture of keratin and lipids. The Steatocystoma are the true sebaceous cysts which consist of walls resemble the duct of sebaceous gland. The treatment modalities of these epidermal inclusion cysts are conventional elliptical excision, minimal excision, punch incision, application of solcoderm. Here we report a case of infected sebaceous cyst which was managed by conventional elliptical excision which resulted in hardly noticeable scar.
