Alveolar soft-part sarcoma of the cheek.

Alveolar soft-part sarcoma is a rare malignant tumour of uncertain histogenesis, the two main sites of which are the lower extremities in adults and the head and neck in children. We know of only three case reports of intraoral locations without tongue involvement. Here, we describe the first case of an alveolar soft-part sarcoma of the cheek which presented in a patient over 30 years old and had an extremely rapid and eventually fatal evolution. We have also reviewed hypotheses about its aetiology.

[Extracorporeal lithotripsy in the treatment of salivary lithiasis. A prospective study apropos of 27 cases].

In a prospective study, we evaluated the efficacy of extracorporeal lithotripsy (ECL) in the treatment of salivary stones. We define the indications for the treatment of submaxillary and parotid stones, depending on the diameter and the location of the stone. Twenty-seven patients were treated by ECL. All had a unique stone, in the salivary duct, with a diameter greater than 2 mm; the site was the parotid gland for ten cases, the submaxillary gland for seventeen cases. After six months, the results from a clinical and ultrasonography point of view, were the following: total efficacy or complete desintegration of the stone: 9 cases; partial efficacy or fragmentation of the calculi, with residual fragments with a diameter of less than 2 mm, which could be flushed out with possible spontaneous clearance: 10 cases; failure or the lack of the reduction in the size of the stone or partial fragmentation into concrements with a diameter of more than 2 mm: 8 cases. Based on our experience and the results reported in the medical literature, we propose an therapeutic approach to symptomatic salivary stones. ECL is the most preferable treatment for stones of the parotid duct or parotid gland. The treatment of stones of the submaxillary gland depends on the site and the size of the calculi; ECL should be proposed as first-line treatment when the stone diameter ranges from 2 to 10 mm and when it is situated in the pelvis of the duct or in the proximal duct; surgical resection of the submandibular gland is indicated when the stone is situated in the gland itself or when the diameter is more than 10 mm; when it is situated in the distal duct, a marsupialization should be performed.

[Laryngeal mask and reduction of nasal bone fractures].

A retrospective study was conducted in 116 patients who underwent anesthesia for reduction of nasal fracture under laryngeal mask for ventilation and protection of the airways. One patient had secondary intubation due to difficult insertion of the laryngeal mask. No episode of hypoxemia related to blood inhalation occurred. The laryngeal mask may be proposed to maintain the airway in this surgical procedure.

[Concomitant radiochemotherapy in locally advanced ORL cancers: a prospective study of 68 cases].

From January 1988 to July 1992, 68 patients presenting with a locally advanced and unresectable carcinoma of the head and neck region were given 3 to 5 courses of chemotherapy (5-FU 1 g/m2, day 1 to 3, cisplatin 4 mg/m2, day 1 and 2, 15 mg/m2 day 8) combined with simultaneous radiotherapy. Patients were enrolled in two protocols. In the initial one a 70 Gy total dose was delivered in 105 days, and in the latter the same dose was given in only 63 days. Toxicity was moderate and acceptable. In the 62 evaluable patients, a complete response was observed in 62%, and partial response in 24%. The complete response rate was higher (80%) in the population enrolled in the second protocol. Overall the median survival is 18 months. At 2 and 3 years, the overall survival is 48% and 30% respectively. These results suggest an influence of overall treatment duration on complete response rate and survival.

[Treatment of salivary gland calculi by extracorporeal lithotripsy].

This study was designed to evaluate the efficacy of extracorporeal lithotripsy (ECL) in the treatment of salivary stones. In a prospective study, 15 patients suffering from sialolithiasis were treated by applying extracorporeally generated shock waves. No patients needed general anaesthesia, sedatives, or analgesics. Treatment was effective in 80% of the 15 patients in this series (5 total efficacy, and 7 partial efficacy). Only minor complications were observed. Lithotripsy is a promising nonsurgical therapy for the treatment of sialolithiasis.

["Beret" flap and other flaps in the reconstruction of cancer related loss of substance of the ear].

Major tissue loss involving the ears and periauricular area due to carcinologic exeresis is an important problem in reconstructive surgery. We present the "béret" flap, a frontal flap with an occipital pedicle, emphasizing the simplicity of the procedure and its reliability. We present our personal experience and data in the literature and recall the main clinical and histological features of these tumors as well as the clinical course and treatment.

[Bucco-sinusal site of primary leiomyosarcoma].

The leiomyosarcoma, a malignant smooth muscle tumor, is common in uterus and gastro intestinal track. Only 27 cases of oral cavity localisation have been report in literature since 1908. We report a case of primary leiomyosarcoma of palate in 26 years old woman. The diagnosis is made by histopathological examination after biopsy. The extension is revealed by clinical symptoms and scan examination. The treatment is based on wide surgery Chemotherapy and radiotherapy could be proposed. The prognosis of the lesion depends of metastatic development, few cases have been present with metastases developed after one year, two years and five years. Generally their localisation are liver, lungs or lymph nodes. In our case after two years post operative a second lesion is revealed and the patient died quickly.

[2 cases of unilateral nasal obstruction related to rhinolithiasis].

Authors report two cases of 31 and 42 year old women who for many years had a unilateral nasal obstruction: first case due to a large polyp, second one due to a mucosal inflammation but both caused by a rhinolithiasis. The latter is formed over several years around a vegetable seed or a piece of material neglected since childhood. The rhinolithiasis is a calcareous concretion formed in layers visible by X-rays. This type of growth is usually enhanced by weak economic development of certain countries.

Middle ear adenoma. A tumor displaying mucinous and neuroendocrine differentiation.

Middle ear adenoma (MEA) is a distinctive, rare entity that appears to be derived from the lining epithelium of the middle ear mucosa. We report four cases of MEA displaying the typical histologic growth pattern. Two distinct tumor cell immunophenotypes were identified in all cases; the first type exhibited positivity with anti-epithelial membrane antigen and anti-keratin antibodies, and the second type showed immunoreactivity with anti-keratin, anti-vimentin, and anti-neuron-specific enolase antibodies. Ultrastructural studies revealed bidirectional mucinous and neuroendocrine differentiation, demonstrated by the presence of two distinct cell types containing apically located mucous granules and basally concentrated neuroendocrine granules, respectively. The presence of neuroendocrine differentiation was supported by the immunohistochemical detection of vasoactive intestinal polypeptide in the tumor cells in one case and neuron-specific enolase in three cases. These findings suggest that the potential for mixed mucinous/neuroendocrine differentiation described in other endodermally derived tumors also exists in middle ear mucosa. We also believe that the rare lesions diagnosed as primary carcinoid tumors of the middle ear might in fact be MEA with predominant or only neuroendocrine differentiation. The clinical course of our four cases and our review of the pertinent literature confirm the benign nature of MEA and indicate that these tumors should be treated by complete local excision without additional therapy.

[Cranial and cervical metastases of vascular nature in thyroid cancer. Apropos of 2 cases].

Vesicular and papillovesicular thyroid cancers provoke metastases in bone, but also of the pseudo-aneurysmal lymph node type. When the latter develop in the craniocervical region, they are often diagnosed as vascular tumors (arteriovenous malformation, glomus tumor). It is now possible, by embolization, to excise these lesions although this involves therapeutic audacity. Surgery is not always sufficient, and complementary 131-Iodine treatment should be used routinely, but it is justified for this type of metastasis as shown by survival rate in these patients.
