Odontogenic keratocysts are benign intraosseous tumors of odontogenic origin that occur most commonly in the jaw. In particular, they have a predilection for the angle and ascending ramus of the mandible. In contrast, odontogenic keratocysts arising in the maxillary sinus are relatively rare. Two such cases are reported herein. In addition, the English literature that concerns odontogenic keratocysts of the maxillary sinus is reviewed.

In this report, we share our experience of a case of maxillo-facial extraskeletal myxoid chondrosarcoma, a very rare location for this neoplasm. In addition, a literature review is provided. The patient, a 61-year-old male, had a maxillary mass encroaching on the nasal cavity. After debulking, the tumor recurred, attaining its pre-surgical proportion in two months. The patient improved clinically with radiation and remained stable for about one year.
However, he ultimately developed metastases in his lung which were treated with palliative chemotherapy with a good outcome lasting three months. We could find only eight reported cases of this tumor in the head region of which two are in the maxilla; hence, ruling out other primary sites is mandatory for a patient presenting with a primary head and neck mass. Surgical removal may be complicated because of the location. A combination of surgery and radiation is the management of choice, with palliative chemotherapy in metastasis.

Inflammatory myofibroblastic tumor (IMT) is a space occupying lesion which is composed of myofibroblasts, plasma cells, and lymphocytes.
IMT of the maxillary sinus is rare and its etiology is unknown. We present a case of inflammatory myofibroblastic tumor occurring in the right maxillary sinus of a 57-year-old woman. Radiologically, this tumor was interpreted as malignant neoplasm. On histologic examination, bundles of spindle cells were admixed with inflammatory cells including mature plasma cells and lymphocytes. On the basis of the immunohistochemical findings and ultrastructural features, we recognized that the intervening spindle cells were myofibroblasts. We discussed etiology and prognostic factors of this tumor.
Utilization of fine needle aspiration cytology(FNAC) in the diagnosis of odontogenic tumors seems to have little attention. Ameloblastoma is the most common epithelial odontogenic tumor. However, the cytologic findings of ameloblastoma are described recently. We report a case of ameloblastoma diagnosed by FNAC. The aspirated blood-tinged mucoid fluid from maxillary mass showed a few clusters of tumor cells with distinct two-cell population: basaloid cells with palisading arrangement and squamous cells with more abundant and eosinophilic cytoplasm. Nuclear atypism, pleomorphism or mitosis were absent. A few keratinized bodies in the tumor cell clusters and the third component, stellate cells were also characteristic.
Dentinogenic ghost cell tumor (DGCT) is an uncommon odontogenic tumor. It is characterized by islands of odontogenic epithelial cells that contain numerous ghost cells and dysplastic dentin. Occasionally, DGCT combines with other odontogenic tumors, such as ameloblastoma. We report here on a 21-year-old female who complained of a tender solid mass in the left maxilla for the 7 month previous to her admission. MRI revealed a relatively well demarcated mass in the left maxilla with heterogenous signal intensity, measuring 3.2 x 2.8 cm, and this mass had invaded the left palate. Microscopically, the tumor was composed of nests of odontogenic epithelium that contained ghost cells and calcification with dysplastic dentin, which is all consistent with DGCT. Localized area showed odontogenic epithelial follicles that had peripheral palisading and satellite reticulum without ghost cells and dentin, and this is consistent with ame- loblastoma. The immunohistochemistry revealed cytokeratins, EMA, S100 and Bcl-2 positivity in areas of the DGCT and ameloblastoma. In the ameloblastoma, Bcl-2 positivity was noted in the palisading basal cells. We concluded that the tumor was an ameloblastoma associated with DGCT.
Metastases to the sinonasal tract are infrequent occurrences from primaries below the clavicles. The total number of reported cases to date is less than 100. There is, however, complete unanimity concerning the histologic type of metastatic neoplasm most often encountered. An interesting phenomenon, generally attributable only to breast and renal cell carcinoma, is the late recurrence of the malignant tumor, even 10 or more years after operation. A 61 year-old-male was admitted to ENT due to frequent epistaxis and right facial swelling. CT scan revealed a huge soft tissue density mass I right maxillary sinus with extension into nasopharynx and deviation of nasal septum. The histologic diagnosis was metastatic renal cell carcinoma. He had left nephrectomy because of renal cell carcinoma, 14 years ago. We report a case of metastatic renal cell carcinoma of maxillary sinus in view of rarity, and a brief review of the literature related to this type of tumor is presented.
