Clinical and radiologic spectrum of glandular odontogenic cysts: A multicenter study of 92 cases. Oral Surg Oral Med Oral Pathol Oral Radiol 2022; 133:593-603. [PMID: 35065903 DOI: 10.1016/j.oooo.2021.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 11/15/2021] [Accepted: 11/20/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The purpose of this multicenter retrospective study was to report the clinical and radiologic features of 92 glandular odontogenic cysts (GOCs) diagnosed over a 20-year period. STUDY DESIGN Histologically confirmed cases of GOC were retrospectively reviewed from 4 oral pathology laboratories in South Africa and Brazil to categorize the clinical and radiologic spectrum of GOCs. RESULTS The mean age of patients was 46 years (range 17-87) with a male-to-female ratio of 1.2:1. GOCs had a mandibular predilection (68%), with 42% of all cases located anteriorly. Additionally, 42% of cases crossed the midline. Radiologically, most lesions were unilocular (53%) and uniformly radiolucent (97%), with well-demarcated borders (93%). Cortical expansion (62%), loss of cortical integrity (71%), and maxillary sinus (67%) and nasal cavity encroachment (72%) were common findings. Significant differences in lesions between the 2 countries were discovered in sex predilection, clinical signs and symptoms, and lesion locations within the mandible and maxilla. CONCLUSION GOCs present with a wide spectrum of clinical and radiologic features, ranging from cysts with typical GOC-like presentations to more aggressive lesions. The need for advanced imaging in the surgical planning of GOCs exhibiting radiologic signs of aggression is justified based on the high recurrence rate.

Arora G, Kumar J, Singh M, Kumar S. Glandular odontogenic cyst of anterior maxilla - A rare case report. Ann Maxillofac Surg 2021; 11:321-324. [PMID: 35265507 PMCID: PMC8848708 DOI: 10.4103/ams.ams_83_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 08/26/2021] [Accepted: 09/28/2021] [Indexed: 11/30/2022] Open
Abstract
Rationale: Glandular odontogenic cyst (GOC) is a rare type of cyst of the jaws, which shares histological features with that of lateral periodontal cyst, botryoid cyst, radicular cyst with mucous metaplasia, or low-grade mucoepidermoid carcinoma, making it difficult to come to a definitive diagnosis. Not many cases of GOC have been reported in the literature. Patient Concerns: A 40-year-old male patient presented with pain in the upper right front tooth region. Mild extraoral swelling, obliterating the right nasolabial fold, was present. Tenderness on percussion was present in involved teeth. Diagnosis: On histopathological examination, GOC was confirmed featuring pseudostratified columnar cells with cilia, goblet cells, and mucous cells. Treatment: Complete enucleation of the cyst was done. Outcomes: No recurrence was noted on 1-year follow-up. Take-away Lessons: Due to high recurrence rate and aggressive nature of the cyst, it is important to plan proper management and long-term follow-up.

[PMID: 31954088 DOI: 10.1111/odi.13281] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 12/16/2019] [Accepted: 01/08/2020] [Indexed: 01/24/2023]
Abstract
OBJECTIVES To investigate the clinicopathological features, BRAF V600E mutation, and MAML2 rearrangement of ameloblastoma with mucous cell differentiation. MATERIALS AND METHODS Five cases of ameloblastoma with mucous cell differentiation were retrospectively studied. Clinicopathological features, BRAF V600E mutation, and MAML2 rearrangement were analyzed. Follow-up information was available for all cases. RESULTS Of five cases, two cases were male and three were female, aged 18-55 years. Four cases were located in the mandible and one case in the maxilla. Histologically, four of the five cases (80%) presented with cystic features and three of the five cases (60%) with varying degrees of squamous metaplasia. The mucous cells were located in the epithelial islands or the luminal aspect of the cystic cavities. The BRAF V600E mutation was found in three of five cases (60%). All the cases showed no MAML2 rearrangement. Two cases were recurrent lesions, and one case had a local recurrence during the follow-up. CONCLUSIONS Ameloblastoma with mucous cell differentiation is closely related to the cystic features, squamous metaplasia, and shows a high prevalence of BRAF V600E mutation. The absence of MAML2 rearrangement reveals that ameloblastoma with mucous cell differentiation and central mucoepidermoid carcinoma (MEC) are two distinct tumor entities.
