We report a rare case of extrapulmonary small cell carcinoma arising in the palatine tonsil treated by combined chemotherapy with irinotecan/cisplatin following irradiation therapy. This chemotherapy regimen was recently found to be effective for small cell lung carcinoma. Our case is the first report of combined irinotecan/cisplatin chemotherapy to treat extrapulmonary small cell carcinoma of the oropharynx.

Intra-arterial (IA) chemotherapy for head and neck cancer is effective and multiple IA concurrent chemoradiation (CCRT) protocols have been reported. However, the role of IA CCRT in the multimodality treatment of head and neck cancer is still controversial. We have treated 5 cases of unresectable T4 maxillary sinus squamous cell carcinoma with IA cisplatin (CDDP) and docetaxel (DOC) and CCRT with oral S-1. We report our experience and the effectiveness and feasibility of this combination as an alternative choice of treatment for inoperable head and neck cancer. The patients received an IA infusion of CDDP (50-70 mg/m(2)) and DOC (50-60 mg/m(2)) through the femoral artery, followed by CCRT with oral S-1. The IA infusion was repeated up to 3 times and the radiation was dosed at up to 60-70 Gy. Complete response was achieved in 4 patients and partial response in one, giving an overall response rate of 100%. The most common grade 3 or 4 toxicities were anorexia (80%), mucositis (80%) and leukopenia (80%), all of which were manageable. CCRT with IA CDDP/DOC and oral S-1 was effective and tolerated. Although preliminary, the response rate encourages further pursuit and definitive evaluation of this combination for the treatment of inoperable advanced head and neck cancer.

This study investigated hearing levels in cases of intractable otitis media with eosinophils and validated the treatment strategy. Medical charts were reviewed retrospectively. The diagnosis was made when the proportion of eosinophils in middle ear secretions exceeded 10%. Twelve patients were identified and treated with an antihistaminergic agent, leukotriene receptor antagonist and topical steroid. The air-bone conductance gap decreased significantly with the relief of subjective symptoms. Bone conduction hearing levels at 4 and 8 kHz were higher than at lower frequencies. There was a significant correlation between subjective symptom duration and bone conduction hearing level at 8 kHz, which diminished with treatment. Compared with suppurative otitis, active otitis with eosinophilia damages high-tone sensory hearing in a time-dependent manner, and antiallergic treatment prevents progression of the high-tone sensory hearing loss. We emphasize the importance of diagnosis and the validity of treatment for intractable otitis media with eosinophils.

BACKGROUND: Synovial sarcoma, generally known as a soft tissue tumor, can also occur in the head and neck region, including the thyroid gland. Cytologic findings are important to differentiate the tumor from other types of neoplasms arising in the thyroid gland. CASE: A 60-year-old man complained of hoarseness. A palpable neck tumor was detected, and a computed tomography scan showed a thyroid tumor accompanied by destruction of the thyroid and cricoid cartilage. The results of a preoperative fine needle aspiration biopsy showed numerous spindle cells with pale cytoplasm and oval nuclei with fine, granular chromatin, all of which suggested a medullary carcinoma. The extirpated thyroid tissue weighed approximate' ly 120 g, and a grayish white, elastic, solid tumor (6.8 × 6.5 cm) was present in the left lobe. Histologically, fasciculation of spindle cells that had proliferated solidly and densely was observed. Also, the expression of a chimera gene, SYT-SSX, was detected in the tumor tissue. CONCLUSION: Synovial sarcoma of the thyroid is extremely rare, and its diagnosis by fine needle aspiration biopsy is generally considered very difficult. The detailed cytologic findings observed here might be helpful with the differential diagnosis of thyroid neoplasms.
