Locally advanced oncocytic carcinoma of the nasal cavity treated with surgery and intensity-modulated radiotherapy.

Oncocytic carcinomas of the nasal cavity are extremely rare. We report 1 patient whose primary tumor and neck lymphadenopathies were under control nearly 2 years after combined surgery and radiotherapy. An 80-year-old man with a history of nasal oncocytoma had received excision twice previously.

Cross-cultural application of the "Sniffin' Sticks" odor identification test.

Background: Odor identification tasks are an important tool for the clinical assessment of olfactory function. However, cultural differences prevent odor identification tests from being used in different countries, because odor identification is strongly dependent on familiarity with these odors. The "Sniffin' Sticks" olfactory test has been developed in Europe and is used for assessment of olfactory function in many European countries.

Toward a better understanding of sinonasal mucosal melanoma: clinical review of 23 cases.

Background: Primary sinonasal mucosal melanoma is a rare disease, occurring far less often than cutaneous lesions. The objective of this study was to review the records of patients diagnosed with primary sinonasal mucosal melanoma.

Methods: We performed a retrospective review of the medical records of 23 patients with sinonasal mucosal melanoma who were treated at Taipei Veterans General Hospital between 1982 and 2002.

The role of ostiomeatal complex obstruction in maxillary fungus ball.

Objective: The aim of this study was to clarify the role of ostiomeatal complex obstruction in maxillary fungus ball.

Study Design And Setting: Comparative study in a hospital setting of the mean Lund-Mackay scores for the anterior ethmoid and frontal sinuses of 54 versus 48 patients with maxillary fungus ball versus chronic unilateral rhinosinusitis, respectively.

Results: In cases with partial opacification in the maxillary sinus, the anterior ethmoid and frontal sinuses were diseased in the chronic unilateral rhinosinusitis group but not in the maxillary fungus ball group.

Localized amyloid deposition in the nasopharynx and neck, mimicking nasopharyngeal carcinoma with neck metastasis.

Amyloidosis results from the deposition of amyloid proteins in organs and tissues. Clinically, it can be classified into systemic and localized forms. Here, we report a case of localized amyloidosis of the nasopharynx and neck.

Madelung's disease.

Madelung's disease is a rare disease of undetermined cause characterized by symmetric deposits of painless, diffuse, subcutaneous adipose tissue on the suboccipital area, the cheeks, the neck, the shoulders and the upper trunk. It is commonest in countries bordering the Mediterranean. The patients are usually middle-aged male alcoholics.

Tuberculosis of the parotid gland: sonographic manifestations and sonographically guided aspiration.

Objective: Involvement of the parotid gland by tuberculosis (TB) is rare. If treated properly, the prognosis of TB of the parotid gland is good. In this retrospective study, we report our experience with sonography and sonographically guided aspiration in the diagnosis of parotid TB.

Parosteal osteosarcoma of the mastoid bone following radiotherapy for nasopharyngeal carcinoma.

Radiation-induced tumors subsequent to nasopharyngeal carcinoma are very rare. To date, no post-irradiation parosteal osteosarcoma of the craniofacial bone has been reported in the English literature. In October 2000, a 57-year-old Chinese woman presented 5 years after radiotherapy for nasopharyngeal carcinoma with a 6-month history of a gradually enlarging left postauricular mass.

Oncocytic Schneiderian papilloma.

Oncocytic Schneiderian papilloma, fungiform papilloma, and inverted papilloma are 3 morphologically separate tumors arising from the Schneiderian membrane. Oncocytic Schneiderian papillomas comprise about 3 approximately 5% of this entity. Old-aged group predominates.

Malignant fibrous histiocytoma of the maxillary sinus presenting as toothache.

Malignant fibrous histiocytoma (MFH) is a high-grade and aggressive sarcoma. It is relatively rare in the head and neck region. Its diagnosis is based on immunohistochemical stains.

Pilomatricoma of the head and neck: a retrospective review of 179 cases.

Objective: To describe the clinical presentations and management of pilomatricoma, formerly known as pilomatrixoma, of the head and neck.

Design: Retrospective study.

Setting: Tertiary care center.

A huge osteoma of paranasal sinuses with intraorbital extension presenting as diplopia.

Osteoma of the paranasal sinuses is a benign, well-defined and slow-growing tumor arising most commonly from the frontal sinus. The ethmoid and maxillary sinuses are less frequently involved. Very seldom, it may involve the orbit, usually by direct extension from the adjacent paranasal sinuses.

Nasopharyngeal lymphoid hyperplasia of an HIV carrier, mimicking nasopharyngeal cancer.

Lymphoid hyperplasia of cervical lymph nodes is a common head and neck presentation of human immunodeficiency virus (HIV) infection. Lymphoid hyperplasia of HIV carrier presenting as nasopharyngeal tumor and neck mass is rarely discussed. We reported a 30-year-old male patient who had left side neck mass for 3 months.

Fibrous dysplasia of the ethmoid sinus.

Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female.

Choanal atresia: an unusual serious complication of complementary and alternative medical treatment.

The use of complementary and alternative medicine (CAM) is common among patients with chronic, long-standing nasal disease. Complications resulting from inappropriate CAM practices are sometimes reported, but serious complications such as choanal atresia and stenosis are rare. We report a case of choanal atresia and stenosis due to herbal drug (ie, chemical) cauterization of the nasal cavity in a 39-year-old man.

Juvenile xanthogranuloma of the nasal cavity.

Juvenile xanthogranuloma (JXG) is the most common non-Langerhans histiocytosis, but it rarely occurs extracutaneously. It sometimes presents with associated neurofibromatosis and Juvenile chronic myalogenous leukemia. We present a case of nasal JXG and discuss the histological characteristics, the classification, and the management.
