“…At the present time however, there is no convincing evidence to link multiple OOCs to NBCCS or Gardner Syndrome. Table 1 summarises four previous reports of bilateral or multiple OOCs reported in the literature [14,[16][17][18]. Similar to the cases reported here, the patients were of a relatively young age, with three of the four reports involving an individual in their third decade.…”

Orthokeratinized odontogenic cysts (OOC) are developmental odontogenic cysts characterised by an orthokeratinized stratified squamous epithelial lining. They were originally believed to be part of the spectrum of Odontogenic Keratocyst, but are now considered to be a distinct entity. They are rare, making up approximately 1% of all odontogenic cysts and they usually occur singly. In this paper we present two new cases of multiple OOCs, and compare them to previous case reports of multiple lesions. The clinical and pathological features are discussed, along with possible diagnostic pitfalls.

“…It presents as solitary, unilocular radiolucency in the posterior mandible with cortical expansion. [ 2 3 4 ] In contrast, the present case is unique as it occurred in an 18-year-old female patient and showed calcification. Only one case has been reported till date with calcification.…”

Orthokeratinized odontogenic cyst (OOC) is a relatively rare odontogenic cyst, distinct from odontogenic keratocyst (OKC). In the 4th edition of WHO Classification of Head and Neck Tumors (2017), OOC has been included as a separate entity in the category of developmental odontogenic cysts. It presents as a unilocular radiolucent lesion in the posterior mandible and is frequently related to impacted teeth, thus mimicking dentigerous cyst. Due to low local aggressiveness and no association with nevoid basal cell carcinoma syndrome, it does not show tendency to recur. When compared to OKC, OOC exhibits substantial number of differences with respect to clinical, pathological and behavioral features and treatment modalities. Hence, recognizing OOC as unique lesion is mandatory to avoid unnecessary overtreatment. This paper aims to report a rare case of OOC associated with impacted tooth, showing calcifications and emphasizes its differences from OKC. Furthermore, the recent concepts about OKC and OOC are discussed.

“…[8][9][10][11][12][13]15,25 Some authors argue that the OKC is an intraosseous counterpart of epidermoid cysts located in the jaw. 27,28 Some developmental odontogenic cysts, including botryoid odontogenic cysts, OKC and GOC have aggressive growth potential and high recurrence rates. The recurrence rates of these cyts have been reported approximately 30% in various studies (range 5%-62%).…”

Aim: Sebaceous glands are rarely observed in odontogenic cysts whereas these structures are the histopathologic features of dermoid cysts. Dermoid cyst growth is slow and its biologic behaviour is silent; after the cyst is removed, recurrence is not observed. However, there are some developmental odontogenic cysts that have a local aggressive course and high levels of recurrence and sebaceous glands may present in these types of cyst. The aim of the study is to evaluate the histopathologic and clinical features of odontogenic cyst with sebaceous gland. Materials and Method: 14 odontogenic cysts with sebaceous glands were reported in the present study. Histopathological features, locations and numbers of sebaceous glands were evaluated. Histochemical (PAS) and immunohistochemical (S100 protein, Pan Cytokeratin, Cytokeratin 19 and EMA ) examinations were also performed. Results: In the present study, 14 patients, 9 (64%) male and 5 (36%) female with a mean age of 42 years were included. The cysts were located in the mandible of 10; while four of them were in the maxilla. All lesions were developmental odontogenic cysts. Microscopic evaluation revealed that sebaceous glands were only in the fibrotic cyst wall in 11 cases, in the intraepithelial location in 1 case and 2 cases showed three different sites as intraepithelial, subepithelial and wall. Conclusions: When the sebaceous glands are observed histopathologically, there is a tendency to diagnoisis as a dermoid cyst. Therefore, the differential diagnosis between odontogenic cyst with sebaceous glands and intraosseous dermoid cysts has great importance for management or different follow-up options.
