Singh HP, Chahal GK, Sharma G, Gandhi P. A systematic review on odontogenic cysts and tumours. J Oral Maxillofac Pathol 2024; 28:268-274. [PMID: 39157825 PMCID: PMC11329078 DOI: 10.4103/jomfp.jomfp_460_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/07/2023] [Accepted: 11/09/2023] [Indexed: 08/20/2024] Open
Abstract
Background There are still certain gaps in the research that need to be filled despite the fact that numerous studies have looked into the transformation of odontogenic cysts into neoplastic lesions. To identify pertinent research that had been published and to synthesise the available data and provide an overview of the current body of knowledge, this review also sought to do so. Materials and Methods Adopting the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a search strategy was implemented across several online databases to search for relevant articles as per the defined selection criterion. Results After the search strategy was complete, 31 studies were chosen. Men tended to have more cancer than women. Swelling and discomfort were the primary pathology-related complaints. Although two cases were not detailed, radiologically, well-defined and poorly defined borders were reported in 18 and 11 participants, respectively. Squamous cell carcinoma with good differentiation (n = 12) was the most common cancer kind. More than 74% of patients were still living 6 months to 10 years following follow-up, four (12.90%) experienced recurrences and/or metastases and two (6.45%) experienced a disease-related mortality between 2 months and a year. Conclusion Prompt surgical follow-ups and cautious excision of odontogenic cysts are essential to avoiding neoplastic change and recurrence. Future research is required to look at possible reasons why odontogenic cysts can convert neoplastically.

Abstract
PURPOSE To assess the prognostic findings of the carcinomatous transformation of odontogenic keratocyst (OKC). METHODS A systematic review of all cases of carcinomatous transformation of OKC was completed, and a case report was included. RESULTS A total of 679 publications were screened, and 37 cases met inclusion criteria. The mean age for patients with malignant transformation of OKC was 45.1 years. Pain (67.5%) and swelling (78.3%) were the most common symptoms. The malignant transformation occurred with increased frequency in the posterior mandible and larger lesions that span greater than 2 subunits of the involved jaw. Resection was the definitive treatment in all cases and 14 cases (46%) utilized adjuvant treatment. CONCLUSIONS Patient outcomes and follow-up was variable in our study such that overall survival was difficult to determine. However, overall survival in malignant transformation of odontogenic cysts of all kinds ranges from 62 to 85% and 30 to 8% for 2 and 5 years, respectively.

Abstract
The aim of this case report was to evaluate the use of Partsch I cystotomy in order to preserve a dental implant located in an odontogenic cyst extended from 3.2 to 4.4. A 50 year-old woman showed a circular, well-defined unilocular radiolucent area, Ø2.5 cm, in the right mandibular region with an oral implant intruding inside it. The overdenture in the mandibular right site showed no clinical mobility. The authors decided to perform a surgical treatment aimed to preserve the implant. The patient underwent Partsch I surgery followed by iodoform gauze insertion replaced weekly for one month, revision of the previous orthograde endodontic treatments, and an acrylic resin obturator prosthesis application for the following two months. The twelve month follow-up showed no clinical mobility of the right lateral mandibular implant prostheses. Radiographical analysis revealed cystic lesion healing and perimplant bone regeneration. This report highlights the opportunity to apply cystotomy when the cyst involves a dental implant and undermines its stability. This possibility is offered by the peculiar clinical scenario where the implant was stabilized by the presence of a previous prosthetic fixation. Our study led to the application of an operative protocol that allowed for the preservation of the implant.

Abstract
Background Recent studies have shown a strong relationship between the expression of osteopontin and oral carcinogenesis. Osteopontin (OPN) has been shown to play a major role in regulating the aggressiveness of cancer cells and promote tumor growth. Odontogenic cysts are an essential aspect of oral and maxillofacial pathology. They are relatively frequent lesions with different clinical behavior. Some of them may have a proliferative pattern of growth and neoplastic nature. Evaluation of osteopontin expression with Ki-67 index may help examine clinical behavior and recurrence of oral squamous cell cancer and radicular cyst patients. Methods A total of 44 oral cavity cancer cases and 21 cysts samples were analyzed by immunohistochemical staining. Data used for analysis were derived from medical records. The following information was obtained from all patients’ medical records: survival, age, sex, lymph node status, tumor size, and location, as well as grade and histologic type of tumor. Expression status of OPN and Ki-67 was statistically assessed. Results Our data demonstrated that for summary immunoreactive scores of OPN and Ki-67 expressions in OSCC vs. RC patients statistical significance was found for both markers’ between OSCC and RC groups. Moreover, osteopontin is significantly higher expressed in larger OSCC tumors. Conclusions In conclusion, the role of OPN expression both in oral squamous cancer cells and radicular cyst and possible correlation with demographic and clinicopathological features remain undetermined in some aspects, further high-powered studies to develop a more standardized assessment of Ki-67 and osteopontin expression in OSCC and are needed.

Initial-Stage Primary Intraosseous Squamous Cell Carcinoma Derived from Odontogenic Keratocyst with Unusual Keratoameloblastomatous Change of the Maxilla: A Case Report and Literature Discussion. Case Rep Otolaryngol 2018; 2018:7959230. [PMID: 29850338 PMCID: PMC5933066 DOI: 10.1155/2018/7959230] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 04/08/2018] [Indexed: 02/07/2023] Open
Abstract
Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant neoplasm derived from odontogenic epithelial remnants in the central jaw bone. Most PIOSCCs originate from odontogenic cysts with a nonkeratinized epithelial lining, especially from radicular/residual and dentigerous cysts. There have been few reports of PIOSCCs derived from the odontogenic keratocyst (OKC), particularly those describing pathological features at the initial stage. The diagnosis of PIOSCC is difficult and based on exclusion of other carcinomas, including metastatic tumors from other primary sites. Here, we report an extremely rare case of initial-stage PIOSCC derived from the OKC with unusual keratoameloblastomatous change of the maxilla.

Abstract
Background The term “primary intraosseous squamous cell carcinoma” was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic odontogenic tumor is considered extremely rare. Case presentation In this case report we report a case of a 50-year-old Sri Lankan woman who complained of pain and increase in the size of a swelling at the anterior mandible, which had been present for over 1 year. The increase was significant for 1 month with accompanying numbness of the left half of her lip. Cone beam computed tomography results revealed an irregular radiolucent lesion involving most of her mandible and, except in the anterior part, very little buccolingual expansion was seen that suggested a keratocystic odontogenic tumor. An excision biopsy of the cyst lining confirmed a squamous cell carcinoma arising from a preexisting keratocystic odontogenic tumor. Conclusions Even though primary intraosseous squamous cell carcinoma arising from a keratocystic odontogenic tumor is considered to be very rare, the present case is comparable to most of the aspects cited in the literature. The current case emphasizes the importance of careful investigation of swellings present in the mandible. Clinicians as well as patients should be aware and detect these changes to avoid being clinically negligent.

Abstract
The aim of this study was to systematically review scientific literature in orderto describe the characteristics and prognosis of malignant entities developing from odontogenic cysts. A search in Pubmed (MEDLINE) and Cochrane databases was conducted. The inclusion criteria were articles published in English related to the malignisation of odontogenic cysts in humans. The exclusion criteria were articles that do not specify the type of odontogenic cyst, malignisation of parakeratinised keratocysts, the presence of an ameloblastic carcinoma and metastasis from distant primary tumours. The selected articles were classified according to Strength of Recommendation Taxonomy criteria. Statistical analysis of the data was carried out using statistical package software SPSS version 22.0. From the 1,237 articles initially obtained, the authors included 3 case series and 45 case reports in the end. Descriptive analysis showed that men have a disposition for malignisation from odontogenic cysts and they frequently appear at the posterior mandible, with pain and swelling being the most frequent signs and symptoms. Follicular cysts were the entities that underwent the most malignant changes with well differentiated squamous cell carcinomas being the most prevalent type of malignancy. The real prognosis of this malignancy is not known because of the heterogeneity of available studies.
Key words:Odontogenic cysts, squamous cell carcinoma, neoplastic cell transformation, oral cancer.

Abstract
Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

Abstract
Primary intraosseous squamous cell carcinoma (PIOSCC) derived from an odontogenic keratocyst (OKC) is a rare malignant neoplasm of the jaws, which is locally aggressive with quite poor prognosis. The incidence of carcinomas arising in odontogenic cysts was reported to be approximately 1-2/1000. The number of well-documented cases of PIOSCC ex OKC is extremely small; hence, no sufficient incidence data are available in the literature. Overall, the survival rate of an individual, which is a period of two years, is very poor, and this can be attributed to the delayed diagnosis. But knowledge of the histopathological and immunohistological features of PIOSCC allows accurate and early diagnosis of the lesion so that an early and appropriate treatment can be instituted for better prognosis. The following report describes an extremely rare case of PIOSCC of the mandible derived from an OKC in a 20-year-old female patient.

Abstract
OBJECTIVE The aim of this study was to evaluate the expression and localization of tight junction proteins (TJPs) or claudins in the keratocystic odontogenic tumor (KCOT) and to correlate with its biological behavior. STUDY DESIGN Five claudins (-1, -3, -4, -5, and 7) were examined immunohistochemically in 25 KCOTs and compared with 10 dentigerous cysts (DCs) and 10 radicular cysts (RCs). RESULTS Marked claudin-3 loss of expression in KCOT basal layer (n=24/25; 96%) compared with DCs (n=1/10; 10%) and RCs (n=5/10; 50%) (P<.05) suggests that claudin-3 downregulation may indicate altered or loss of basal cell polarity and impaired barrier function of KCOT lining epithelium and this might contribute indirectly to its biological behavior. In contrast, claudins-1, -4, -5, and -7 distribution patterns were less distinctive in all three entities, suggesting that these TJP molecules probably play limited roles in influencing their different growth potentials. CONCLUSION Present findings suggest that differential claudin expressions in the lining epithelium of KCOTs, DCs, and RCs probably reflect their neoplastic or nonneoplastic nature.

Abstract
Odontogenic cysts in the maxilla are common but a malignant change in an odontogenic cyst is a comparatively a rare occurrence; however, these entities present with clinical and radiographic features similar to benign, expansible, central, odontogenic tumor, or cyst of the jaws. A patient reporting with squamous cell carcinoma arising from an odontogenic keratocyst of right maxilla has been worked up clinically, radiographically, and pathologically. The case was surgically managed and followed up. A 54-year-old male patient with a compressible, rapidly growing swelling of right maxilla was clinically diagnosed to be a case of odontogenic cyst. On radiologic examination it appeared similar to a cystic lesion. An incisional biopsy obtained from the cyst wall showed it to be odontogenic keratocyst with histologic evidence of malignant transformation. The pathogenesis of the tumor, the biologic progression, and prognosis and overall clinical and histopathogical features of this rare malignancy is reported and discussed.

Abstract
PURPOSE To review the literature on primary intraosseous squamous cell carcinoma (PIOSCC) associated with odontogenic cyst. METHODS All well-documented cases of PIOSCC published between 1938 and 2010 were collected. Only cases of PIOSCC arising from the lining of an odontogenic cyst, including the keratocystic odontogenic tumor, were selected. Age, sex, signs and symptoms, affected jaw, cyst type, treatment, histopathology, and outcome were recorded. RESULTS The mean age was 60.2 years (range 1.3-90). There were 80 (69%) men and 36 (31%) women. Mass and pain were the most common presenting symptoms. The mandible was affected in 92 (79%) patients and the maxilla in 24 (21%). It was a residual/radicular cyst in 70 (60%) patients and a dentigerous cyst or a keratocystic odontogenic tumor in the remaining 40%. The histopathology was well-differentiated SCC in 53 (46%) patients and moderately differentiated SCC in 47 (40%) patients. Fifty-three (46%) patients were treated with surgery alone and 44 (38%) with surgery and radiotherapy. Fifty-eight (62%) patients survived 2 years and 36 (38%) survived 5 years. CONCLUSION PIOSCC has a predilection for men (M/F ratio of 2.22:1), affects mainly adults in their 6-8th decades, occurs most frequently (79%) in the mandible, and is associated mainly with a residual/radicular cyst. Histologically, the well-to-moderately differentiated SCC was the most common. Surgery alone or combined therapy of surgery and radiation was the most common approach. The prognosis is 62% surviving 2 years and 38% 5 years.
