骨外型牙源性钙化上皮瘤1例

牙源性钙化上皮瘤(calcifying epithelial odontogenic tumor,CEOT)亦称Pindborg瘤,是一种良性、生长缓慢、但有局部侵袭性的牙源性上皮肿瘤,发病率占所有牙源性肿瘤的0.4％～3％,据文献报道称,该瘤多发生于颌骨内磨牙区(94％),骨外型极少见(6％).现将我科收治的一例骨外...     

骨外型牙源性钙化上皮瘤

骨外型牙源性钙化上皮瘤极为罕见,通过复习1966～2011年英文MEDLINE与1994～2011年中文CHKD中收录的文献,仅有37例骨外型牙源性钙化上皮瘤的个案报告。根据上述资料分析,发现该瘤具有以下临床特点,就诊年龄3～71岁,平均35.8岁;男13例,女19例,男女比例为1∶1.46;肿块直径0.5～4 cm,平均1.76 cm;好发部位主要是牙龈,累及下颌与上颌牙龈的比例为1∶1;组织学特征表现与骨内型牙源性钙化上皮瘤基本相同;复发率为5.4%。因该瘤具有浅表骨侵蚀能力,应行完整的肿瘤切除结合骨面刮治术。

钙化上皮瘤及牙源性钙化上皮瘤的临床病理分析

目的：探讨钙化上皮瘤及牙源性钙化上皮瘤的临床表现、诊断及外科处理原则。方法：对13例钙化上皮瘤和4例牙源性钙化上皮瘤患者的临床资料进行回顾性分析。结果：所有患者均经手术治疗。钙化上皮瘤患者平均年龄11．2岁,小于10岁者占69．2％（10例）;位于头颈部8例（61．5％）,四肢4例（30．8％）,躯干1例（7．7％）。牙源性钙化上皮瘤患者平均年龄38．75岁,均位于颌骨。两种肿瘤无明显性别差异,均有复发、恶变的报道。结论：钙化上皮瘤和牙源性钙化上皮瘤在临床表现和病理诊断上具有明显差别,是两种不同的肿瘤;牙源性钙化上皮瘤具有局部浸润性生长,手术切除必须彻底。

Treatment of a calcifying epithelial odontogenic tumour with tube decompression: a case report

Conservative treatment of odontogenic tumours with decompression or marsupialisation is not common, but can be done successfully in those with a cystic pattern. We present a calcifying epithelial odontogenic tumour that was treated by tube decompression and subsequent enucleation.     

Central calcifying epithelial odontogenic tumour in the posterior maxilla: a case report

The calcifying epithelial odontogenic tumour (CEOT), or Pindborg tumour, is a rare, benign odontogenic tumour. CEOT is usually asymptomatic and an incidental radiological finding, often presenting as a mandibular radiolucency with flecks of calcific material. We report an unusual case of CEOT in the left posterior maxilla of a 46‐year‐old male that was associated with an unerupted tooth. The tumour in this case caused non‐specific sinus symptoms and appeared radiographically similar to an odontoma or ossifying fibroma due to its dense calcific contents. Diagnosis was confirmed histologically following surgical removal of the lesion, which showed classic CEOT histomorphology. We report this case to highlight the unusual clinico‐radiologic presentation and illustrate the diagnostic difficulties that can occur with radiolucent and/or radiopaque lesions in the jaws.     

Calcifying epithelial odontogenic tumour presenting at a surgical site: case report

We describe the management of a calcifying epithelial odontogenic tumour with an atypical clinical presentation at the site of a previously surgically exposed impacted maxillary canine in a 51-year-old woman.     

Calcifying epithelial odontogenic tumor of the maxilla with ulcerative stomatitis: a case report

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic tumor, known as Pindborg tumor. Although ulcer formation was reported in one previously involving the peripheral maxilla, such change of the overlying mucosa has been reported in intraosseous CEOT. We report maxillary CEOT in a patient who complained of spontaneous pain due to extensive ulcer formation of the oral mucosa.     

Cystic variant of calcifying epithelial odontogenic tumor

The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm of the jaw. Clinically, calcifying epithelial odontogenic tumor manifests as an intraosseous lesion (central type) in the majority of cases (95%). Extraosseous or peripheral lesions account for less than 5% of cases. Calcifying epithelial odontogenic tumor can be associated with an impacted tooth and give a radiographic simulation of dentigerous cyst. Most calcifying epithelial odontogenic tumors are solid in nature, histopathologically, and might have few cyst-like spaces within them. However, a true cystic calcifying epithelial odontogenic tumor is a rare possibility. We describe a case of a true cystic variant of calcifying epithelial odontogenic tumor in a 30-year-old male, which to our knowledge, is only the second reported case.     

Non-calcifying variant of calcifying epithelial odontogenic tumor with Langerhans cells

Calcifying epithelial odontogenic tumor (CEOT) is a rare type of odontogenic tumor. The most characteristic feature of the classical CEOT is the presence of amyloid globules and Liesegang ring calcification in the tumor tissue. Here, we present a non-calcifying variant of intraosseous CEOT with the presence of Langerhans cells within tumor epithelial nests in a 52-year-old Taiwanese woman. The patient was referred from a local dentist to our hospital for treatment of a unilocular radiolucent lesion at the right anterior region of the maxilla. The lesion was excised. Microscopically, the tumor was composed of small nests or strands of odontogenic epithelial cells and amorphous eosinophilic globules of amyloid-like materials in a loose fibrous connective tissue stroma. The tumor epithelial cells were positive for pan-cytokeratins (AE1 and AE3). Langerhans cells demonstrated by anti-CD1a staining were found in nests or strands of tumor epithelial cells. The eosinophilic globules were positive for Congo red and showed green birefringence when subjected to polarized light. Review of the English literature revealed two cases of non-calcifying variant of intraosseous CEOT with Langerhans cells in the anterior and premolar regions of the maxilla. Taken together, we suggest that the non-calcifying, Langerhan cell-rich variant of CEOT may have a distinct predilection for occurrence in the anterior and premolar region of the maxilla in contrast to the classical CEOTs that usually occur in the molar and ascending ramus area of the mandible.
