[Arterial chemoembolization in the combined treatment of malignant tumors of the tongue and maxilla: preliminary results]

The authors made a clinical evaluation of the efficiency of regional bolus chemotherapy and embolization as a stage of combined therapy in patients with inoperable cancer of the tongue and maxilla complicated by bleeding episodes. Carotid angiography by attempting to make chemoembolization was performed in 15 patients. The procedure could not be done in full in 2 (13%) patients due to transient vascular and neurological disorders. The remaining 13 (87%) patients had successful chemoembolization of tumor-supplying arteries with 5-fluorouracil (700 mg/m2) and methotrexate (40 mg/m2) in combination with finely cut hemostatic sponge and fragments of metallic spirals (n = 12) or regional bolus injection of a cytostatic (n = 1) without arterial occlusion. After embolization, bleeding episodes ceased in all the patients. Full (n = 1) and partial (n = 6) responses to treatment or stabilization of the process (n = 5) were noted in 12 (92%) cases, progression was only in 1 (8%) case. The study suggests that chemoembolization of the branches of the external carotid artery in patients with cancer of the tongue and maxilla contributes to the arrest of chronic tumorous bleeding and to the reduction in the risk for acute A combination of systemic multidrug therapy, radiation therapy, and chemoembolization stabilizes a tumorous process in most patients.

Target-specific multimodality endovascular management of carotid artery blow-out syndrome

We describe a novel multimodality endovascular approach to safely control hemorrhage from a carotid artery pseudoaneurysm and tumor vasculature associated with a squamous cell carcinoma. This approach was used in the case of a 68-year-old man who had previously undergone a laryngectomy, chemotherapy, and brachytherapy and who subsequently experienced acute oropharyngeal bleeding. Angiography detected a carotid artery pseudoaneurysm and significant tumor vascularity. A target-specific multimodality approach was taken to embolize the potential etiologies for both the current and any future hemorrhages. Stent-assisted coiling of the pseudoaneurysm was successful. The tumor blush was treated with polyvinyl alcohol particles and both retrievable and nonretrievable coils. Endovascular surgeons have become increasingly involved in the management of patients with carotid injuries and with neoplasms in and around the skull base. Current endovascular technology provides a rapid target-specific approach to the treatment of carotid artery blow-out syndrome and has a greater potential to lower morbidity than does carotid sacrifice.

A case of multiple endocrine neoplasia type 2B undiagnosed for many years despite its typical phenotype

We report the case of a 24-yr-old man with a typical phenotype of multiple endocrine neoplasia type 2B (MEN 2B). The patient had previously undergone minor surgery to remove multiple tumors on the lip, but he had no further examinations. MEN 2B was suspected owing to characteristic multiple ganglioneuromatosis when the patient presented with a goiter associated with high levels of plasma calcitonin and CEA. Aspiration biopsy cytology revealed medullary thyroid carcinoma (MTC), and abdominal computed tomography and nuclear scanning with metaiodobenzylguanidine revealed bilateral adrenomedullary tumors. Adrenomedullary function tests showed high levels of serum and urinary fractionated catecholamines, and genetic analysis showed a point mutation in the codon 918 (M918T) of the RET gene. The patient was diagnosed with MEN 2B and underwent right adrenalectomy and total thyroidectomy. No distant metastasis of the MTC was noted although MEN 2B had remained undiagnosed since the ganglioneuromatosis was first noticed. MEN 2B is a rare hereditary disorder, but the occurrence of characteristic ganglioneuromatosis was quite helpful in making the diagnosis.

MR imaging of airway obstruction in infants and children

Accurate diagnosis is important in the evaluation of airway disorders of infants and children. Today, multiple imaging techniques are available to evaluate the pediatric airway. In general, it is best to start with simple and readily available examinations, which may provide a diagnosis in most cases, and progress to more sophisticated studies such as MR imaging. We performed magnetic resonance (MR) imaging of 45 infants and children with symptoms of airway obstruction, 14 of 45 patient symptoms were related to masses of the airway and 31 of 45 patient symptoms were related to vascular compression.

Tongue lesions in the pediatric population

OBJECTIVE

To describe the spectrum of pediatric tongue lesions treated surgically at Columbia-Presbyterian Medical Center from January 1990 to December 1999.

STUDY DESIGN AND SETTING

Retrospective case-series at the pediatric hospital of a tertiary care, academic medical center.

RESULTS

Seventeen patients were identified. Their ages ranged from 1 to 132 months (median, 7 months). Eight lesions were located anteriorly: mucous cyst (1), polyp (1), chronic inflammatory mass (1), hamartoma (1), squamous papilloma (2), cavernous hemangioma (1), and vascular malformation (1). Four lesions were located posteriorly: teratoma (1), glial choristoma (1), osseous choristoma (1), and benign epithelial cyst (1). Finally, there were 5 diffuse lesions including macroglossia (4) and massively infiltrating congenital lymphatic malformation (1). Symptoms included respiratory distress (3) and dysarthria (3); all other children were asymptomatic.

CONCLUSIONS

This series revealed an interesting spectrum of rare solid tumors; compared with other large series, fewer lymphatic and vascular malformations were seen. Presenting symptoms, differential diagnosis, and surgical approach were differentiated according to lesion location.

[Neck abscess as primary manifestation of head and neck carcinoma: implications for diagnostic management]

BACKGROUND

Neck abscesses and deep neck infections are common diseases in the field of otorhinolaryngology. However, malignant lymph node metastases presenting as abscesses are uncommon and have rarely been described up to now.

PATIENTS

A retrospective review between March 1997 and August 1999 was conducted of 40 patients with deep neck abscesses.

RESULTS

In five patients (12.5%) the histological diagnostics revealed a malignancy. From these, in 3 cases the cervical abscess was the primary clinical symptom of an oropharyngeal as well as a hypopharyngeal carcinoma. With further 2 patients, the neck-abscess was located as first clinical sign of a metachronous lymph node metastases after oropharyngeal carcinoma. Aerobic bacteria were recovered in 18 patients, anaerobes alone in 3 and mixed aerobic and anaerobic bacteria in 6 patients. Bartonella henselae was recovered in 7, Mycobacterium tuberculosis in 3 and Actinomyces israelii in 1 patient.

CONCLUSIONS

A biopsy of the abscess wall is recommended in establishing the diagnosis. The indication for a simultaneous panendoscopy--especially in patients with typical risk for malignancies--to exclude a primary tumor in the aerodigestive tract should be regarded generously. Neck abscesses should be considered in the differential diagnosis of head and neck carcinoma.

Pleomorphic adenoma of tongue base causing dysphagia and dysphasia

A case of an 87-year-old female with pleomorphic adenoma of the tongue base is reported, with a review of the literature. The tumour had enlarged gradually over a period of three years, causing dysphagia and dysphasia. Computed tomography and magnetic resonance imaging showed that the tumour was exophytic and occupy the oropharynx with little extension into the muscle tissue. The tumour was resected by CO2 laser. Histological examination revealed a benign pleomorphic adenoma that originated from the minor salivary gland of the tongue base.

Impact of comorbidity, symptoms, and patients' characteristics on the prognosis of oral carcinomas

OBJECTIVES

To evaluate the impact of comorbidities, symptoms, and patients' characteristics on the 5-year overall survival of patients who underwent surgery for cancer of the oral tongue or floor of the mouth and to improve the survival estimates by the creation of a new staging system.

PATIENTS AND METHODS

A cohort of 110 patients with squamous cell carcinoma of the oral tongue or floor of the mouth, who were admitted to a tertiary cancer hospital from January 1, 1990, to December 31, 1994, and who underwent surgery was studied. Multivariate analysis distinguished that patients' characteristics, symptoms, and comorbidities have a significant impact on 5-year overall survival. This functional severity index combined with the TNM stage created the extended clinical severity staging system.

RESULTS

The 5-year overall survival was 33.4%. Survival by TNM cancer stage was 64.6% (stage I), 67.5% (stage II), 28.9% (stage III), and 13.1% (stage IV) (chi(2) = 22.88, P<.001). When patients were categorized according to the extended clinical severity staging system, survival was as follows: 74.0% (stage 1), 47.1% (stage 2), 28.6% (stage 3), and 8.4% (stage 4) (chi(2) = 38.67, P<.001).

CONCLUSION

Clinical variables have a prognostic impact on oral cancer that is surgically treated, and the consistency of results confirms that survival estimates can be improved by the addition of these elements to the TNM classification, creating a more powerful and precise system in the determination of a prognosis.

New multilobe "accordion" flaps for three-dimensional reconstruction of wide, full-thickness defects in the oral floor

When reconstructing a wide, full-thickness intraoral defect, the following principles are necessary for active food transport and improved swallowing and speech. First, the flap should touch the palate and obliterate the oral cavity. Second, jaw or flap excursion should not be hindered by tethering of the flap in the neck. And third, all surfaces of the tongue and oral floor, and the dead space of the floor should be reconstructed. To accomplish these goals, two new designs, similar to an accordion, using an anterolateral thigh flap and a deep inferior epigastric perforator flap have been developed. The outlines of multilobe flaps create an accordion-type structure of the tongue and oral floor complex. The advantages of the new designs using anterior thigh or deep inferior epigastric perforator flaps are follows: First, three-dimensional intraoral reconstitution allows maximal movement postoperatively of the reconstructed tongue. Second, the donor sites are so far from the tongue that simultaneous flap elevation is possible for tumor resectioning. Third, even in obese patients, totally or partially thin flaps are available. And fourth, in most patients the donor defects can be closed directly.

Pemphigus with pemphigoid-like presentation, associated with squamous cell carcinoma of the tongue

A 53-year-old woman presented with an inoperable squamous cell carcinoma of the tongue associated with tense large bullae consistent with bullous pemphigoid, preceded by a prodrome of urticarial plaques. The histological findings showed a regenerating subepidermal blister with eosinophils and no acantholysis. Direct immunofluorescence study, however, showed positive staining for IgG and C3 throughout the epidermis consistent with pemphigus. The blistering eruption had no mucosal involvement and responded to low dose corticosteroids. Our patient may represent another presentation of a 'paraneoplastic pemphigus spectrum'.

Prenatal diagnosis of airway compromise: EXIT (ex utero intra-partum treatment) and foetal airway surgery

Four cases of potential airway obstruction diagnosed in the early antenatal period are presented. Their management is outlined, and the need for a multidisciplinary team approach to these problems is highlighted. The experience of the ex-utero intrapartum treatment (EXIT) procedure is presented, and the first attempt at intra-uterine tracheal surgery is introduced.

Oral carcinoma in a young man: a case of dyskeratosis congenita

We report a 28-year-old male with a voluminous growth of the tongue, present for 6 months. The histological examination revealed a squamous cell carcinoma. The patient was also affected by oral leukoplakia, nail dystrophy, reticulated poikiloderma of the neck and hyperkeratosis of palms and soles. On the basis of clinical features and histological findings, as well as findings from the family, the diagnosis of dyskeratosis congenita (DKC) was made.

Lymphangioma of the tongue presenting as Ludwig's angina

In this paper we present a case of a 6-year-old child who presented with Ludwig's angina caused by an infected tongue base lymphangioma. We provide a literature review of tongue lymphangioma and Ludwig's angina in the paediatric population. Both Ludwig's angina and tongue base lymphangioma are rare conditions in their own right and a combination of the two has not previously been described in the literature.

Oral glycopyrrolate alleviates drooling in a patient with tongue cancer

Although sialorrhea and drooling are uncommon symptoms in cancer patients, they can cause considerable discomfort, inconvenience and social embarrassment. In this article we describe a patient with tongue cancer who was successfully treated with oral glycopyrrolate 0.4 mg 3 times daily. Glycopyrrolate is a quaternary ammonium compound. In contrast to the recommended treatment with scopolamine, glycopyrrolate is virtually without side effects to the central nervous system because it penetrates the blood-brain barrier poorly. Glycopyrrolate has a slow and erratic absorption from the gastrointestinal system, but even low plasma levels are associated with a distinct and long-lasting antisialogic effect.
