Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms. However, there are some debates on whether the symptoms are directly related with retention cyst. These cysts typically do not require treatment. However, when accompanied by symptoms, treatment can be administered for diagnostic and therapeutic purposes. We report a case in which facial pain is caused by a maxillary retention cyst suspended from an infraorbital nerve.

Malignant lymphoma of the maxillary sinus is very rare. A case of diffuse large B-cell lymphoma (DLBCL) of the left maxillary sinus is presented here. A 59-year-old man came to our hospital complaining of swelling under the left lower eyelid without any other symptoms. Imaging examination including CT and MRI detected a tumor in the left maxillary sinus. The tumor was invasive into left orbit. The biopsy revealed a diffuse large B-cell lymphoma. The tumor cells were positive to CD20, CD79a, CD45. In conclusion, a very rare case of DLBCL of the maxillary sinus was reported.

Glomangiopericytoma is a rare neoplasm of the nasal and paranasal sinuses comprising less than 1% of all tumors of the said region. We report of a 59-year-old hypertensive male who presented with epistaxis. CT scan findings showed a mass in the right nasal cavity with extension into the ethmoid and sphenoid sinuses. Histopathologic diagnosis was glomangiopericytoma confirmed with immunohistochemistry studies. Prognosis is favorable with complete resection of tumor and long-term monitoring.

BACKGROUND AND OBJECTIVES: There are various subtypes in lymphoma of the nasal cavity and paranasal sinuses. This study aimed to compare the clinical differences between NK/T cell lymphoma and B cell lymphoma in the nose and paranasal sinuses. MATERIALS AND METHODS: From 1991 through 2003, 18 patients were diagnosed with lymphoma by histopathologic biopsy (NK/T cell 13 : B cell 5). We reviewed the medical records retrospectively regarding subjective symptoms, physical findings, and PNS CT findings. RESULTS: The most common symptom of NK/T cell lymphoma was nasal obstruction (8/13), and the main endoscopic finding was ulcerative small lesion. The PNS CT finding of NK/T cell lymphoma was homogenous, poorly enhanced, small mass. In contrast, the most common symptom of B cell lymphoma was periorbital swelling (2/5), and the main endoscopic finding was fungating mass. The PNS CT finding of B cell lymphoma was heterogenous, well-enhanced, large mass with bone destruction. The location of NK/T cell lymphoma was the inferior or middle turbinate in the nasal cavity, whereas the location of B cell lymphoma was the ethmoid or maxillary sinus. CONCLUSION: It is suggested that there may be significant clinical differences between NK/T cell lymphoma and B cell lymphoma in the sinonasal cavity.

OBJECTIVE: The study is to evaluate our results of patients with sinonasal inverted papilloma (SIP) undergoing endoscopic sinus surgery and to investigate the recurrence relative factors of SIP. METHOD: A retrospec- tive analysis was performed of medical records for 54 cases SIP treated with endoscopic resection. Compared to pre operation imaging evaluation and intraoperative observation, efficacy assessments included endoscopy during follow-up after operation and combined with CT examination results. RESULT: The incidence of 54 cases with ethmoid sinus, part of the lateral wall of the nasal cavity was higher. The recurrence rate was higher in the cases invaded front and/or inferior wall of maxillary sinus, frontal recess. There was no case with middle turbinate. Canceration with the same time accounted for 1.85%. CONCLUSION Misdiagnosis as polyps, the lesion sites of tumour, involving the frontal recess, front and inferior wall of maxillary sinus are the risk factors of recurrence. The preoperative accurate judgment of the primary tumor site and surgical resection completly are the most effective means of preventing recurrence. Postoperative endoscopy examination combined with CT examination is an effective means for the evaluation of recurrence.

Lung cancer is known to metastasize to a wide range of organs. The main sites for the metastatic foci are the mediastinal lymph nodes, brain, bones, adrenal glands, and the liver. Metastases to the paranasal sinuses are rare. However, a metastatic maxillary tumor may be the initial presentation of an unknown primary malignancy. Here, we report a case of a lung cancer that metastased to the maxillary sinus because of its rarity and its effect on the treatment of the disease.
