Multiple Epidermoid Cysts of Face: A Case Report

Introduction: Epidermoid cysts are cystic malformations filled with keratin and lipid rich debris. They generally present as benign, soft, and freely movable, slowly enlarging, and non-tender masses, commonly located on the face, neck and trunk of the body. They are more commonly seen in ovaries and gonads, and less often in head and neck region. Approximately 7% of epidermoid cysts are present in the head and neck region and about 1.6% are found in the oral cavity. They can be either congenital or acquired in origin. Congenital epidermoid cyst occurs at third and fourth intra-uterine life due to entrapment of ectodermal elements entrapped during midline fusion of first and second branchial arches. However, acquired epidermal cysts occur due to implantation of epidermal elements following cystic transformation. Case presentation: In this article, we discuss a case of epidermoid cysts presenting in multiple areas of the face which clinically appeared to as acquired nevi (mole). Management/Prognosis: Based on clinical appearance and provisional diagnosis, treatment of mole was made. The lesions were excised by electrocautery and sent for histopathological evaluation. Conclusion: There was a drastic difference between the clinical appearance and histopathological picture seen. A thorough knowledge about etiology, clinical history and histopathology is needed to reach an accurate diagnosis

Keratocystic odontogenic tumor with ossification and calcification: A case report with unusual histological findings.

The keratocystic odontogenic tumor (KCOT), formerly known as odontogenic keratocyst, is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features. Hard tissue deposits, which usually take the form of dystrophic calcifications, cartilaginous tissue, or dentinoid, are uncommon findings in the connective tissue capsule of the KCOT. We report a case of a 33‑year‑old female with KCOT showing osseous tissue and calcified deposits close to its epithelial lining, which is an extremely rare occurrence. A brief review on the reported prevalence of hard tissue deposits in KCOTs and possible mechanisms that has been implicated in mineralization and bone formation has been discussed.
