1/798. Verruciform xanthoma associated with squamous cell carcinoma.

    Verruciform xanthoma (VX) is a rare lesion of unknown etiology that is typically solitary and predominantly located within the oral cavity. Less commonly, they arise on the skin, with the majority of cases occurring in anogenital sites. They can be confused clinically with verruca vulgaris, condyloma, leukoplakia, verrucous carcinoma, and squamous cell carcinoma. Histologic features include acanthosis with uniform elongation of the rete ridges and xanthomatous cells that lie in and are typically confined to the papillary dermis. Although epidermal atypia is not a characteristic finding, we describe an unusual case of VX that has features of both VX and squamous cell carcinoma. In addition, there was a VX with typical histologic characteristics located at a separate site in the same patient. This case is also the first to our knowledge to be reported on the neck and axilla and is the third case associated with cutaneous graft versus host disease secondary to bone marrow transplant for acute lymphoblastic leukemia.

2/798. 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.

3/798. Axillary nodal metastases in head and neck cancer.

    BACKGROUND: Axillary node metastasis is an uncommon occurrence in squamous carcinoma of the upper aerodigestive tract. methods: The tumor registry of The Johns Hopkins University Department of otolaryngology-head and neck Surgery contained four cases of metastasis to the axilla from head and neck primary sites. A retrospective review of these cases was performed. RESULTS: Each patient had been initially treated for cancer years earlier including surgery and radiation to the neck. A recurrent cancer or a new primary then developed in the upper aerodigestive tract prior to the development of the axillary metastases. CONCLUSIONS: The common course of disease in these patients suggests that alteration of the lymphatic anatomy by previous treatment may have caused a new pattern of metastatic spread upon reseeding from the mucosa, resulting in the axillary metastases. Routine surveillance of the axillae by physical examination and/or computerized imaging in at risk patients may permit the early diagnosis of axillary metastases.

4/798. head and neck reconstruction using lateral thigh free flap: flap design.

    Eleven lateral thigh free flaps were used in head and neck reconstruction, transferred on the basis of the second perforator as well as the third perforator of the profunda femoris artery. The lateral thigh free flap was useful and reliable in head and neck reconstruction and was versatile in flap design. Due to the wide cutaneous territory of the lateral thigh flap, the skin island could be designed freely in the lateral thigh region. Careful patient selection is mandatory for good results. The pinch test and an understanding of the variety of subcutaneous thicknesses in the lateral thigh region are helpful in designing a skin island of adequate thickness. Other considerations in flap design are discussed.

5/798. carcinoma of the uterine cervix metastatic to behind the zygomatic arch: a case report.

    PURPOSE: We propose to present a novel case of a genital malignancy metastatic to the head and neck. carcinoma of the uterine cervix is the third most frequent malignancy of the female genital tract. Early detection and improved radiation and surgical techniques have resulted in better control of the pelvic tumor and a greater incidence of distant metastasis. Metastases to the soft tissue of the head and neck region have not been reported. methods: We present the first known case of a 35-year-old woman with cancer of the uterine cervix who presented with metastasis to the soft tissue behind the zygomatic arch. RESULTS: The patient received radiation therapy to the zygomatic region and cisplatin therapy with a near-complete remission. CONCLUSION: This case shows that not all squamous cell cancers detected above the clavicles are from a thoracic or a head and neck primary tumor. The atypical location should alert the physician to suspect distant metastasis, rather than locoregional disease.

6/798. Stomal recurrence invading the cervicothoracic esophagus and upper mediastinum: resectability and the creation of a safe anterior mediastinal tracheostoma.

    Surgical salvage for stomal recurrence is a for midable problem for head and neck surgeons. The two factors of considerable significance are resectability and establishment of a safe anterior mediastinal tracheostoma. A case of stomal recurrence invading the cervicothoracic esophagus and upper mediastinum is presented. Total esophagectomy and upper mediastinal dissection was performed. The esophagus was reconstructed immediately with a pedicled gastric flap. The omentum on the gastric pedicle was wrapped around the trachea to reduce the likelihood of erosion into the great vessels and to supplement the lateral blood supply to the trachea. No serious postoperative complications were observed. We believe that the total esophagectomy improved the resectability, and that the bulk of the gastric pedicle and the use of the omentum prevented significant postoperative complications associated with an anterior mediastinal tracheostoma.

7/798. Palatal lymphoepitheliomas and a review of head and neck lymphoepitheliomas.

    AIM: Lymphoepithelioma is principally a tumour of the nasopharynx with only sporadic cases arising elsewhere in the head and neck. We describe the clinical and imaging features of a group of rare lymphoepitheliomas related to the palate. patients AND methods: Four patients with lymphoepithelioma of the palate are described. In each case we retrospectively reviewed the clinical records, laboratory results, and imaging which consisted of computed tomography (CT) and ultrasound in all four cases and magnetic resonance imaging (MRI) in two patients. RESULTS: All four patients were ethnic Chinese (non-smokers, non-drinkers). All cases were Epstein-Barr virus (EBV) related. Tumour was related to the palate in two cases and extended into the nasal cavity in one patient. The fourth patient had a tumour in the floor of the nasal cavity with invasion of the palate on biopsy but not imaging. Cervical lymphadenopathy was seen in two cases, and the nasopharynx was normal in all the four patients. CONCLUSION: Lymphoepitheliomas occur in the region of the palate, where they are also EBV related in southern Chinese. Compared with the keratinizing squamous cell carcinomas, patients with lymphoepitheliomas have a better prognosis and these tumours are not tobacco or alcohol related. They should not be misdiagnosed as metastatic nasopharyngeal carcinoma (NPC), particularly since the nasopharynx is invariably normal on imaging and adequate nasopharyngeal biopsy is negative for malignancy.

8/798. head and neck cancers associated with Madelung's disease.

    BACKGROUND: Madelung's disease is a rare lipodystrophy that presents with multiple fatty masses in the neck, trunk, and upper extremities. The fatty accumulation is considered a benign disease, but compression of the aerodigestive tract may occur in long-standing disease. methods: Eight Chinese patients with Madelung's disease were reviewed. All were male, aged 48 to 67 years, with a history of disease ranging from 4 to 20 years. Two of the eight patients developed aerodigestive symptoms and were subsequently found to have head and neck cancers. These two patients are described. RESULTS: The possible mechanism that may account for an increase in malignant tumors of the airway in this group of patients is the synergistic effect of smoking and alcohol abuse as risk factors for both Madelung's disease and malignant tumors of the airway. Currently it is recommended that these patients should have their fatty lesions removed surgically. The removal of fat facilitates examination of the neck for signs of cervical lymphadenopathy in malignant disease. CONCLUSIONS: patients with Madelung's disease should be followed regularly. The development of aerodigestive symptoms should be fully investigated with endoscopy and imaging. The cause of symptoms should not be attributed to fatty compression until a carcinoma of the upper airway has been excluded.

9/798. Anaplastic squamous cell carcinoma (SCC) in a patient with chronic cutaneous graft-versus-host disease (GVHD).

    We describe an allogeneic bone marrow (BM) recipient who developed aggressive, metastasizing squamous cell cancer (SCC) of the skin, and discuss possible risk factors in the development of this secondary solid tumor. The patient had been treated with cyclosporine (CsA), methyl-prednisolone and thalidomide for 3 years because of extensive de novo chronic cutaneous GVHD occurring 1 year after BMT. Ten years after BMT a locally invasive and metastasizing SCC occurred on the patient's neck, and diagnosis was confirmed by H&E histopathology and cytokeratin-immunohistochemistry. Analysis of genomic dna did not reveal p53 mutations nor were HPV sequences detectable. risk factors included conditioning for BMT with total body irradiation (TBI) and cyclophosphamide (Cy), immunosuppressive treatment for GVHD, and extensive exposure to UV radiation before and after BMT. Despite surgery and adjuvant chemotherapy with 5-fluorouracil (5-FU) the patient died 1 year after the diagnosis of SCC.

10/798. Clinical delivery of intensity modulated conformal radiotherapy for relapsed or second-primary head and neck cancer using a multileaf collimator with dynamic control.

    BACKGROUND AND PURPOSE: Concave dose distributions generated by intensity modulated radiotherapy (IMRT) were applied to re-irradiate three patients with pharyngeal cancer. patients, MATERIALS AND methods: Conventional radiotherapy for oropharyngeal (patients 1 and 3) or nasopharyngeal (patient 2) cancers was followed by relapsing or new tumors in the nasopharynx (patients 1 and 2) and hypopharynx (patient 3). Six non-opposed coplanar intensity modulated beams were generated by combining non-modulated beamparts with intensities (weights) obtained by minimizing a biophysical objective function. Beamparts were delivered by a dynamic MLC (Elekta Oncology Systems, Crawley, UK) forced in step and shoot mode. RESULTS AND CONCLUSIONS: Median PTV-doses (and ranges) for the three patients were 73 (65-78), 67 (59-72) and 63 (48-68) Gy. Maximum point doses to brain stem and spinal cord were, respectively, 67 Gy (60% of volume below 30 Gy) and 32 Gy (97% below 10 Gy) for patient 1; 60 Gy (69% below 30 Gy) and 34 Gy (92% below 10 Gy) for patient 2 and 21 Gy (96% below 10 Gy) at spinal cord for patient 3. Maximum point doses to the mandible were 69 Gy for patient 1 and 64 Gy for patient 2 with, respectively, 66 and 92% of the volume below 20 Gy. A treatment session, using the dynamic MLC, was finished within a 15-min time slot.
