Odontogenic Cyst with Verrucous Proliferation Exhibiting Melanin Pigmentation
Hindawi Limited, 2017Co-Authors: Nidhi Manaktala, Karen Boaz, Krupa Mehta Soni, Srikant Natarajan, Junaid Ahmed, Keshava Bhat, Nandita Kottieth Pallam, Amitha Juanita LewisAbstract:Verrucous proliferation arising from Odontogenic Cysts is a rare entity. We report an unusual case of an infected Odontogenic Cyst with verrucous proliferation and melanin pigmentation in a 13-year-old male patient who presented with an intraoral swelling in relation to impacted teeth 26 and 27. The enucleated lesion was diagnosed as an Odontogenic keratoCyst and the patient died within two years of presentation due to multiple recurrences. The clinical, radiological, and microscopic features of the lesion are presented with an attempt to discuss the etiopathogenesis. The case hereby reported is uncommon with only eight cases reported in the literature

ameloblastomatous calcifying Odontogenic Cyst a rare histologic variant
Journal of Oral Pathology & Medicine, 2003Co-Authors: D Aithal, B S Reddy, Sumita Mahajan, Karen Boaz, Mala KambojAbstract:Calcifying Odontogenic Cyst (COC) is an uncommon developmental Odontogenic Cyst first described by Gorlin in 1962. It is considered as extremely rare and accounts for only 1% of jaw Cysts reported. Because of its diverse histopathology, there has always been confusion about its nature as a Cyst, neoplasm or hamartoma. Several subclassifications have been proposed. Here, we present a case of calcifying Odontogenic Cyst with ameloblastic proliferation - an extremely rare histologic variant. The classical histologic features of the lining epithelium in the form of cords and presence of characteristic ghost cells were seen along with ameloblastomatous proliferations. Ameloblastomatous COC microscopically resembles uniCystic ameloblastoma except for the ghost cells and calcifications within the proliferative epithelium. The nature of the COC is controversial. The case is presented here for its rarity, and difference between ameloblastomatous COC and ameloblastoma ex COC has been emphasized.

Recurrent calcifying Odontogenic Cyst involving the maxillary sinus.
Oral surgery oral medicine oral pathology oral radiology and endodontics, 2004Co-Authors: John Spencer M. DanielsAbstract:The calcifying Odontogenic Cyst is an uncommon lesion that occurs in both jaws, however involvement of the maxillary sinus is rare. The accepted mode of treatment is enucleation with curettage since it is generally believed that recurrence following such treatment is extremely rare. Of the reported cases of recurrent calcifying Odontogenic Cysts, none have involved the maxillary sinus. This report is of a large recurrent calcifying Odontogenic Cyst involving the maxillary sinus, eroding the orbital floor as well as anterior and medial walls of the maxillary sinus and displacing an impacted upper canine into the nasal cavity, in a 45-year-old male patient, 8 years after the initial enucleation.

synchronous ameloblastoma and orthokeratinized Odontogenic Cyst of the mandible
Journal of Oral Pathology & Medicine, 2006Co-Authors: Eduardo Rodrigues Fregnani, Danyel Elias Da Cruz Perez, Fernando Augusto Soares, Fabio De Abreu AlvesAbstract:The simultaneous occurrence of ameloblastomas with Odontogenic Cysts or other non-Odontogenic lesions have already been described as combined lesions. However, we are unaware of any report in the English literature of simultaneous occurrence of ameloblastoma and orthokeratinized Odontogenic Cyst (OOC) occurring as completely distinct lesions. This report shows a case of synchronous ameloblastoma and OOC, located on posterior regions of the mandible, but in distinct sides.

orthokeratinized Odontogenic Cyst ooc clinicopathological and radiological features of a series of 10 cases
Diagnostic Pathology, 2019Co-Authors: Nasir Uddin, Maha Zubair, Jamshid Abdulghafar, Zia Ullah Khan, Zubair AhmadAbstract:Background Orthokeratinized Odontogenic Cyst (OOC) is a rare, developmental Odontogenic Cyst which was considered in the past to be a variant of Odontogenic keratoCyst (OKC) later renamed as keratoCystic Odontogenic tumor (KCOT). The treatment of OOC is by enucleation and the prognosis, following enucleation is excellent with a recurrence rate of less than 2%. On the other hand, OKC has a recurrence rate between 8 and 25% after enucleation. Thus it is important to differentiate between the two entities.

Calcifying Odontogenic Cyst Associated with an Orthokeratinized Odontogenic Cyst
Head and Neck Pathology, 2008Co-Authors: Vanessa Fátima Bernardes, Júlio César Tanos Lacerda, Maria Cássia Ferreira Aguiar, Ricardo Santiago GomezAbstract:Odontogenic tumors composed of two or more distinct types of lesions are unusual. In this paper, a case of an Odontogenic lesion characterized by simultaneous occurrence of areas of calcifying Odontogenic Cyst (COC) and orthokeratinized Odontogenic Cyst (OOC) is described. The lesion was asymptomatic and presented at the radiographic examination as a unilocular well-delimited radiolucency extending from left incisor to right premolar area in the mandible. To date, this is the first report of COC associated with an OOC.
