1/186. Hurthle cell carcinoma of the thyroid gland with extensive tumor necrosis: a case report.

    Hurthle cell neoplasm of the thyroid gland is rarely associated with tumor necrosis. We report a case of Hurthle cell carcinoma of the thyroid gland with extensive necrosis. An 82-year-old man had had a right neck mass for more than 10 years. Approximately two to three weeks before he was hospitalized, this neck mass became progressively enlarged. An 131I scan could not demonstrate the right lobe of the thyroid gland, while the contralateral lobe was unremarkable. A 99mTc-sestamibi scan showed increased uptake on the lesion side. Fine needle aspiration cytology showed necrosis with macrophages in the initial aspirate, and the secondary aspirate appeared suspicious for a Hurthle cell tumor. The patient had a total thyroidectomy, and the pathology proved to be Hurthle cell carcinoma with tumor necrosis.

2/186. The adenocarcinoma of the larynx: in aim of a clinic case. Histologic, immuno-histochemistry and electron microscope studies.

    adenocarcinoma "not otherwise specified" of the larynx appears to be extremely rare. We report a case of adenocarcinoma "NOS" arising in the larynx of a 72 year-old white man. The neoplasia was ALCIAN and PAS negative. Immuno-histochemical studies revealed negative immunoreactivity from NSE, chromogranins and S100; cytokeratin was positive. Electron microscopy revealed electrodense granules of varying sizes, but with no obvious central core surrounded by a limiting membrane. The patient underwent a total laryngectomy and functional neck dissection, with mandibular extension. And he is free of tumor after 4 years postoperatively.

3/186. Gastric adenocarcinoma with tonsil and submaxillary gland metastases: case report.

    Local invasion, hematogenous and lymphatic metastases are the major modes of spreading gastric cancer. The most common sites of metastases in patients with gastric cancer are liver, peritoneum, omentum, lungs and mesentery. Of the two pathological types of gastric cancer, intestinal-type gastric cancer showed preferential metastasis to the liver, whereas the diffuse-type showed a preference for peritoneal involvement and lymph node metastasis. However, metastases of gastric cancer to the head and neck regions are not common. The hematogenous route appears to account for a great majority of metastases to the head and neck regions. Malignant neoplasm metastases to major salivary glands or tonsils are not common. Several patients with cancers from the infraclavicular area have been reported with parotid gland or tonsil metastases. However, metastasis of gastric adenocarcinoma to the tonsils or submandibular glands is rare. We present a patient with recurrent gastric adenocarcinoma with both tonsil and submandibular gland metastases which is even rarer.

4/186. Postoperative radiotherapy of paranasal sinus tumours: a challenge for intensity modulated radiotherapy.

    BACKGROUND AND PURPOSE: Intensity modulated radiotherapy (IMRT) is used in our department for treatment of paranasal sinuses. We describe the methodology that was developed together with the clinical implementation, illustrated by a case report. MATERIAL AND methods: Patient history, treatment and short follow-up are described. An IMRT, obtained by superposition of static beam segments was implemented. Electronic portal images, compared to digitally reconstructed radiographs (DRR) were used to evaluate and adjust patient positioning. RESULTS, DISCUSSION AND CONCLUSION: IMRT is an appropriate and feasible treatment technique for head and neck cancer in anatomical regions that are difficult to treat. A high tumour dose can be combined with a good sparing of the surrounding organs at risk (OAR's).

5/186. Leptomeningeal metastases from ethmoid sinus adenocarcinoma: clinico-radiological correlation.

    A patient with sinonasal adenocarcinoma is presented with leptomeningeal metastases affecting multiple cranial nerves and spinal nerve roots. head and neck cancer is known to be an extremely rare source for leptomeningeal metastatic spread. The cranial nerves, the spinal cord and roots and the cerebral hemispheres can be affected in case of leptomeningeal metastatic spread. Examination of the CSF is the hallmark of the diagnosis if leptomeningeal metastatic spread is suspected, but this case illustrates that the combination of specific clinical features on one hand and specific lesions on the Gd-enhanced T1-weighted MRI study on the other hand is reliable enough to make a presumed diagnosis if the CSF analysis remains negative. We suggest that in our patient direct leptomeningeal spread occurred through the cribriform plate to the CSF, followed by further spread in a gravity dependent way.

6/186. Parotid lymph node metastasis from adenocarcinoma of the urachus.

    The parotid gland and its lymph nodes are frequent sites of metastases from head and neck cancers. However, metastasis from a distant primary below the clavicle is unusual. These originate from a variety of sites, most commonly the lung, kidney and breast. A case of a 59-year-old woman with parotid lymph node metastasis from an adenocarcinoma of the urachus, diagnosed on the basis of two discrete periparotid masses on CT and the patient's history, is presented.

7/186. Six-year disease-free survival of a patient with metastatic eyelid squamous cell carcinoma and colon adenocarcinoma after repeated postoperative adoptive immunotherapy.

    A 74-year-old male was affected concurrently with squamous cell carcinoma of the left eyelid and adenocarcinoma of the colon, both with lymph node metastasis. He underwent exenteration of the left orbit with left modified radical neck dissection and subsequently resection of the transverse colon with regional lymph node dissection. The patient has been treated by an adoptive immunotherapy as a sole postoperative modality without receiving any chemotherapeutic agents causing immunosuppression. For the adoptive immunotherapy, autologous peripheral blood lymphocytes were activated with an immobilized anti-CD3 antibody and IL-2 for 14 days (the CD3-AT cells). The infusion with 1.38 x 10(10) CD3-AT cells has been repeated 150 times in total at the time of writing. Neither recurrence nor additional metastasis has been detected for 6 years after surgery.

8/186. Adeno-endocrine cell carcinoma of the gallbladder.

    We encountered a rare case of adeno-endocrine cell carcinoma of the gallbladder in an 81-year-old woman. Imaging study revealed a common bile duct stone. Endoscopic sphincterotomy was performed, and the stone was extracted successfully. Thereafter, cholecystectomy was performed. A papillary tumor was found in the neck of the gallbladder. Histologically, the tumor consisted of two components, well differentiated adenocarcinoma and endocrine cell carcinoma. However, no clinical signs of tumor hormonal activity were observed. The tumor cells in the area of the endocrine cell carcinoma were small and round. Histochemical studies of these tumor cells were positive for chromogranin a and Grimelius silver impregnation. The tumor cells in the area of the adenocarcinoma were well differentiated adenocarcinoma and included goblet-type cells with a tubular structure or solid growth pattern. These adenocarcinoma cells stained positively for alcian blue and periodic acid-Schiff, and both types of tumor cells stained positively for carbohydrate antigen and carcinoembryonic antigen. It was suggested that the histogenesis of the endocrine cell carcinoma of the gallbladder was closely related to that of the adenocarcinoma.

9/186. Cutaneous metastasis to the head and neck from colonic carcinoma.

    A case of metastatic facial skin involvement from colonic carcinoma is reported where, despite radiotherapy given preoperatively, the tumour continued to grow. The patient remained disease free for 8 months after excision and reconstruction, but died of pulmonary metastases.

10/186. A long-term course of a primary urethral/paraurethral adenocarcinoma.

    The authors report a rare case of primary urethral/paraurethral adenocarcinoma in a female patient. The tumor was first detected at the external and internal urethral orifices, with later recurrences in the region of the urinary bladder neck. histology did not reveal the exact origin of the malignancy. The patient was treated by transurethral resection, regularly repeated during the 3-6-monthly checks. Five years after diagnosis she remains symptom free and has a high quality of life.
