1/197. Intraoperative respiratory failure in a patient after treatment with bleomycin: previous and current intraoperative exposure to 50% oxygen.

    patients treated with bleomycin (BLM) are at risk of developing acute respiratory distress syndrome (ARDS) post-operatively, and this has been associated with high intraoperative concentrations of oxygen. We report progressive arterial desaturation noticeable 2 h after the start of a 4-h radical neck dissection for which the anaesthesia included 50% O2 in N2O. The patient had received two courses of bleomycin within the previous 2 months and had undergone an uneventful right hemiglossectomy under shorter but otherwise similar anaesthesia 4 weeks previously. His pulmonary function tests before the second procedure showed a slight depression of diffusing capacity (DLco) to 80% of predicted and minimal airway obstruction consistent with his history of smoking. The pulse oximetric reading during his second procedure reached 75%, but rose to 95% after treatment with methylprednisolone salbutamol and inspired O2 concentrations between 80% and 100%. By the end of the procedure, he satisfied the criteria for ARDS and was transferred to the ICU, where he developed bilateral pneumonia, deteriorated and died of multiple organ failure. This case suggests that the risk of hyperoxic pulmonary damage in patients exposed to bleomycin may increase not only with the degree and duration of hyperoxia in a given exposure, but also with the latent effects of recent previous exposure. Near normality of pulmonary function tests cannot be taken as reassurance, and small changes may have more adverse prognostic significance than in patients who have not been exposed to bleomycin.

2/197. Squamous cell metastasis from the tongue to the myocardium presenting as pericardial effusion.

    Cardiac metastasis from head and neck cancer is rarely encountered. We present a base-of-tongue squamous cell carcinoma with metastasis to the heart that was diagnosed antemortem. autopsy series indicate that tongue cancer may metastasize more frequently to the heart than from other head and neck sites. However, none of these studies was controlled. Most importantly, cardiac metastasis should be suspected in any patient with cancer in whom new cardiac symptoms develop. The diagnosis is best confirmed with two-dimensional echocardiography or cardiac MRI. A myocardial or endocardial biopsy specimen can be obtained with angiographic guidance. Despite the improvement in diagnostic capability, available treatments are only palliative. All patients eventually die of their metastatic disease.

3/197. The blastic variant of mantle cell lymphoma arising in Waldeyer's tonsillar ring.

    We present three cases of blastic mantle cell lymphoma with an unusual initial manifestation in Waldeyer's ring with methods for differentiating it from other blastic neoplasms of the head and neck. All cases presented with a feeling of fullness in the area of the mass. Morphologically, the tumours were blastic with a high mitotic rate (three to nine per high power field). All were B-cell phenotype with coexpression of CD43. In all cases cyclin d1 and bcl-2 were positive and CD23 negative. Blastic mantle cell lymphoma occurring in Waldeyer's tonsillar ring may be mistaken for other high grade haematopoietic neoplasms. immunohistochemistry and awareness of this type of lymphoma are helpful in differentiating it from other neoplasms.

4/197. Follicular carcinoma in ectopic thyroid gland. A case report.

    Ectopic thyroid rest can be seen anywhere along the path of descent of the gland. The most ectopic thyroid tissue is a thyroglossal duct cyst associated with normal thyroid gland. Sublingual location is less common than a lingual ectopia. True malignant transformation in ectopic thyroid tissue is extremely rare. Such a malignancy is virtually always diagnosed only after surgical excision of the lesion at pathological examination. This report discusses a case of ectopic thyroid follicular carcinoma in the right submandibular region in the absence of orthotopic thyroid, discovered by chance after the surgical excision performed for a preoperative ultrasonically and cytologically misdiagnosed submandibular gland adenocystic carcinoma. The possible aetiology of such an unusual anatomical relationship is discussed as well as the importance of thyroid scanning, ultrasound and/or CT in neck lumps.

5/197. Malignant ectopic thymoma in the neck: a case report.

    We report a case of malignant ectopic thymoma in the neck. Contrast-enhanced CT of the neck showed a well-defined inhomogeneously enhancing mass in the left jugulodigastric chain. One year after surgery, the mass had metastasized to the tongue base, and CT of the neck showed an ill-defined densely enhancing mass with lymphadenopathy.

6/197. Alveolar soft part sarcoma of the tongue: report of an unusual pattern in a child.

    A case of an unusual, primary alveolar soft part sarcoma of the tongue in a 3-year-old boy is presented. Alveolar soft part sarcoma is a rare malignant tumor that presents more frequently in the head and neck region of infants and children. To date, only six cases of lingual alveolar soft part sarcoma presenting in the first decade of life have been reported in the English literature. The patient has undergone surgical resection without adjuvant chemotherapy or radiation. Thus far, the patient does not manifest persistent or recurrent disease.

7/197. Alveolar soft part sarcoma of the tongue.

    We report a case of alveolar soft part sarcoma--a rare malignancy that presented as a swelling at the base of the tongue in a 5-year-old child. Only about one-quarter of the few reported cases arise within the head and neck, the tongue and orbit being the favoured sites.

8/197. Possibilities of preventing osteoradionecrosis during complex therapy of tumors of the oral cavity.

    In recent years, there has been a dramatic increase in the number of tumors of the head and neck. Their successful treatment is one of the greatest challenges for physicians dealing with oncotherapy. An organic part of the complex therapy is preoperative or postoperative irradiation. Application of this is accompanied by a lower risk of recurrences, and by a higher proportion of cured patients. Unfortunately, irradiation also has a disadvantage: the development of osteoradionecrosis, a special form of osteomyelitis, in some patients (mainly in those cases where irradiation occurs after bone resection or after partial removal of the periosteum). Once the clinical picture of this irradiation complication has developed, its treatment is very difficult. A significant result or complete freedom from complaints can be attained only rarely. attention must therefore be focussed primarily on prevention, and the oral surgeon, the oncoradiologist and the patient too can all do much to help prevent the occurrence of osteoradionecrosis. Through coupling of an up-to-date, functional surgical attitude with knowledge relating to modern radiology and radiation physics, the way may be opened to forestall this complication that is so difficult to cure.

9/197. Papillary carcinoma of the base of the tongue. Case clinic.

    Ectopic lingual thyroid tissue is an uncommon developmental anomaly. Tumours of identical pathological characteristics as those arising in the eutropic thyroid tissue, may be present in ectopic locations. There are very few cases of malignant tumours reported in the literature. Here we report a review of this pathology and we describe a case of a papillary carcinoma of the base of the tongue, located in ectopic lingual thyroid tissue, in a 66 year-old white man, complaining of dysphagia and oral bleeding. Surgical treatment was carried out, consisting of radical resection of the right hemineck, tumour resection, right hemiglossectomy and total thyroidectomy. Postoperative treatment with 131I and substitutive thyroid hormonal therapy was prescribed.

10/197. tongue cancer in younger patients.

    tongue cancer involving the anterior tongue often presents at an early stage. The aetiology is strongly associated with smoking and alcohol abuse similar to other squamous cell carcinomas (SCC) of the head and neck (HN). Surgery and radiotherapy, either alone or together, offer the prospect of cure in the majority of patients. However, there remains a group of younger patients less than 40 years old for whom outcome is often poor. Presented here is the case of a 24-year-old woman who developed SCC of the anterior tongue. Despite treatment, loco-regional relapse occurred resulting in death. The literature identifies a distinct subgroup of younger patients who develop HN SCC, particularly of the oral cavity. The aetiology remains unclear. Recent studies have looked at the prognostic significance of various new non-clinico-pathological markers in HN SCC (including p53 tumour suppressor gene, cyclin d1 protein, Ki 67 antigen and tumour angiogenesis). The majority of these studies, as expected, have involved the typical HN patient (male, aged > 60 years old). However, the relevance of these studies is of likely importance to all patients diagnosed with HN SCC. The recent use of these non-clinical-pathological markers in HN SCC, including reference to such studies in younger patients, is discussed. The English literature during the past 30 years is reviewed with reference to the diagnosis of tongue SCC in younger patients.
