The cystic Figure1. Bucco-lingual width of the lesion lining is composed of one to five cell layers of squamous or cuboidal epithelium with a fibrous connective tissue according to inflammation.3,4 The epithelium shows areas of focal thickening with glycogen containing clear cells observed around the cyst lining.5-8 The BOC and LPC often have a subepithelial zone of hyalinization.6,9 The odontogenic epithelium responsible for the cystic lining in the BOC and LPC is hypothesized to arise from three possible sources: (1) a reduced enamel epithelium (REE), (2) epithelial cell rests of Malassez (ERMs), or (3) residuals of dental lamina.4 Figure 2. CT shows unilocular cystic lesion about 15 mm in diameter in the right mandibular region. CASE REPORT A 57 year-old male patient referred to our clinic, Ankara University Faculty of Dentistry Department of Oral and Maxillofacial Surgery for evaluation of a swelling seen in the right anterior mandible. His systemic diseases include: diabetes mellitus type 2 and hypertension. He had been aware of the asymptomatic swelling during the past 8 months. At the time of dental examination, an expansion behind the right mandibular canine was observed, panoramic radiography and CT revealed a well-defined unilocular radiolucent lesion distal to the right mandibular canine in the edentulous region (Figures 1, 2 and 3). The canine tooth was devital. There was no paresthesia, tenderness or other changes in sensation. An excisional biopsy was performed Figure 3. Operative view of the intra-oral approach. that included the canine tooth under local anesthesia (Figures 4, 5 and 6). The pathology report was indicated as a diagnosis of BOC. Multiple cystic spaces lined by nonkeratinized stratified squamous epithelium were seen histopathologically (Figure 7). The cyst lining was thickest layer of the three cell layers with areas of plaque-like thickening in the epithelium. 44 The cyst wall was composed of fibrous tissue exhibiting extravasated blood cells without inflammation. At the 9-month follow-up, the clinical appearance of the surgical site was normal (Figures 8, 9 and 10). The patient is using total prosthesis and there is no complaining about the RADIOLUCENCY IN MANDIBULA Figure 4. Enucleation and tooth extraction Figure 6. Post-operative intra-oral photograph.

DISCUSSION BOC usually involves the mandibular premolar-canine area, followed by the anterior region of the maxilla.10 The most affected group is adults older than 50 years.11 Although some of the reported cases of BOC have shown a multilocular radiolucency, this image is not characteristic for BOC. There are similarities between BOC and some odontogenic tumors such as ameloblastoma, odontogenic myxoma in terms of appearance. Preoperative differential diagnosis can be carried out by means of incisional biopsy. Some authors demonstrated that this lesion frequently presents as a unilocular radiographic image, thus resembling a variety of other odontogenic cysts or neoplastic conditions.12 Figure 7. In the right side of the picture stratified squamoid plaques were shown. The enucleation of a BOC or LPC results in an osseous cavity or defect. Lehrhaupt et al.4 treated a residual LPC defect that perforated the facial and lingual mandibular cortex in a similar characterization. A demineralized freeze-dried bone allograft had been used and a membrane had not been placed over the bone graft material. Nart et al.5 reported 45 CLINICAL DENTISTRY AND RESEARCH Figure 8. Post-operative 1-month panoramic radiography Figure 9. Post-operative 9-month panoramic radiography Figure 10.Post-operative 9-month intra-oral photograph There is no comment about the state of vital and nonvital adjacent teeth to the lesion in the literature. When a radiolucent lesion is seen related with teeth that is identified on a radiographic examination , histologic examination must be performed if it has a diagnosis about normal, vital pulps. BOC is known as a recurrent odontogenic cyst. The recurrence rate may range between 15% and 20%.13 The histopathological appearance of BOC is quite typical in the presence of epithelial proliferations (plaques). The proliferation rate of the epithelial lining can be determined to estimate the possibility of recurrence. The recurrence risk of BOC is similar to odontogenic keratocyst. The characteristic that distinguishes BOC from LPC is the larger size of the BOC because LPC has a limited growth potential.14 The importance of the differentiation between LPC and BOC is due to the histologic multilocular aspect of the BOC that induces this lesion more expansive. Thereby, increasing the possibility of recurrence because its complete surgical removal is more difficult.9,14 BOC shows some histopathological similarities to the glandular odontogenic cyst (GOC) or sialo-odontogenic cyst (SOC) depending on the presence of mucous cells and surface columnar cells.10,15,16 However, the best classification for these lesions is BOC. These lesions can be seen at opposite ends of a spectrum. The presence of mucous cells does not suspend the BOC from an odontogenic origin, this characteristic of BOC has been reported in a variety of odontogenic cysts such as the dentigerous cyst with a metaplastic phenomenon.17 Furthermore, immunohistochemical studies18,19 have suggested that the GOC is a histological variant of BOC. According to a prevalent opinion, main reason for recurrence can be a failure during the complete removal of the multilocular lesion during surgery. A long term post-surgical follow-up is necessary for a patient whit a diagnosis of BOC.3,13 Alternative treatment techniques for BOC can be considered such as odontogenic keratocyst.11 REFERENCES a similar treatment of a residual LPC osseous defect using guided tissue regeneration with a demineralized freezedried bone allograft and resorbable collagen membrane. At the 7-month follow-up, they found significant radiographic bone fill, which was also seen on surgical reentry. Because of the recurrence risk of BOC, wide excision is required for treatment. In the current case, we treated the patient by enucleation. 46 1. Wheathers DR, Waldron CA. Unusual multilocular cysts of the jaws (botryoid odontogenic cysts). Oral Surg 1973; 36: 235-241. 2.
