Abstract
Dermoid cysts (DCs) and epidermoid cysts (ECs) are uncommon developmental cysts affecting the oral cavity. This study aims to evaluate patients with oral DCs and ECs and their demographic and clinicopathologic features. A retrospective descriptive cross-sectional study was performed. A total of 105,077 biopsy records of oral and maxillofacial lesions from seven Brazilian oral pathology centers were analyzed. All cases diagnosed as oral DCs and ECs were reviewed, and clinical, demographic, and histopathological data were collected. The series comprised 32 DCs (31.4%) and 70 ECs (68.6%). Most of the DCs occurred on the floor of the mouth (n = 14; 45.2%) of women (n = 17; 53.1%) with a mean age of 34.6 ± 21.6 years. All DCs were lined partially or entirely by stratified squamous epithelium (100%). Chronic inflammatory cells, melanin pigmentation, multinucleated giant cell reaction, and cholesterol clefts were observed in the fibrous capsule . Most of the ECs affected the labial mucosa (n = 20; 31.7%) of men (n = 39; 56.5%) with a mean age of 48.0±19.8 years. Microscopically, most ECs (n = 68; 97.1%) were lined entirely by stratified squamous epithelium. Two cysts (2.9%) showed areas of respiratory metaplasia. Chronic inflammatory cells, melanin pigmentation, multinucleated giant cell reaction, and cholesterol clefts were also observed in the fibrous capsule. Conservative surgical excision was the treatment of choice in all cases. Oral DCs and ECs are uncommon and often clinically misdiagnosed lesions. Clinicians should consider DCs and ECs in the differential diagnosis of soft tissue lesions in the oral cavity, mainly located on the floor of the mouth and labial mucosa.

Comparison of cytokeratin expressions among orthokeratinized odontogenic cysts, epidermoid cysts and odontogenic keratocysts: An immunohistochemical study. J Oral Maxillofac Pathol 2021; 24:472-478. [PMID: 33967483 PMCID: PMC8083416 DOI: 10.4103/jomfp.jomfp_243_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 07/08/2020] [Accepted: 09/25/2020] [Indexed: 11/23/2022] Open
Abstract
Background: Orthokeratinized odontogenic cysts are keratinizing jaw cysts and due their association with impacted teeth and keratinaceous content, they resemble odontogenic keratocysts but differ in regards to biological behaviour, being less aggressive. To unravel the nature of OOCs, as they resemble epidermoid cysts histologically and due to their developmental resemblances to OKCs, this study was conducted. Aim and Objective: To compare the cytokeratin expressions of CK 10 and CK 19 among orthokeratinized odontogenic keratocysts, epidermoid cysts and odontogenic keratocysts by immunohistochemical study. Materials and Methods: 30 cases of all three cysts were collected, 10 cases in each of these cysts (OOCs, EDCs and OKCs) were incubated with CK 10 and CK 19 markers respectively. IHC staining was performed and assessed all layers of epithelium. All the data were analyzed using SPSS software, P values were obtained by the Chi-square test and Fisher's test. Results: The expression pattern of CK10 showed 100% positive in both OOCs and EDCs with significant difference in OKCs. CK19 expression, between EDCs and OKCs was significant but between OOCs & EDCs and OOCs & OKCs was found to be statistically insignificant. Conclusion: CK 10 expressions in both OOCs and EDCs were near identical both in terms of expression and patterns of expression in surface and spinous layers. OOCs may not be distinguished from EDCs both histologically and with CK 10 expression. CK19 expression between OOCs & EDCs and OOCs & OKCs was statistically insignificant. Thus, based upon CK 19 expression, no significant differences were found between OOCs & EDCs and OOCs & OKCs, implying that OOCs resemble both EDCs and OKCs.

Abstract
Examination of the oral cavity should be an essential part of the newborn assessment. Early detection of congenital disorders is essential to begin appropriate medical or surgical therapy and to prevent complications that could profoundly affect a child's life. The present review aims to describe the main anomalies of the oral cavity in infants and provide images in order to help the physician in current clinical practice.
