1/31. Surgical approach to a giant fibrolipoma of the supraglottic larynx.

    This paper describes the surgical procedures for a fibrolipoma that first appeared as a giant tumour in the hypopharynx and extended to the cardiac antrum of the oesophagus. At the initial surgery, a pedunculated tumour originating from the left arytenoid of the larynx was found to occupy the cervical as well as thoracic oesophagus and was thus removed through a lateral pharyngectomy. A histological examination revealed fibrolipoma. However there was a recurrence of the tumour in the arytenoid and the patient suffered from dysponea. In addition, a submucosal tumour was also found in the left false vocal fold. At the second surgery, the masses in the arytenoid and false vocal fold were subtotally removed without damaging the mucosa. The mucosa of the arytenoid was sutured to the thyropharyngeal muscle on the same side and the arytenoid swelling disappeared almost completely. The post-operative course has been uneventful for more than two years.

2/31. Recurrent respiratory papillomatosis with esophageal involvement.

    OBJECTIVE: To report a case of recurrent respiratory papillomatosis with diffuse involvement of the esophagus in a child. DESIGN: Retrospective case report and literature review. SETTING: Tertiary Children's Hospital. CONCLUSION: endoscopy is recommended for detection of esophageal papillomas, especially in patients with significant laryngeal lesions or post-cricoid involvement.

3/31. Preexisting gastric carcinoid in a gastro-omental free flap.

    The authors present a 72-year-old man with an extensive medical history including stage III squamous cell carcinoma of the right pyriform sinus diagnosed approximately 10 years before this report. They were asked to evaluate the patient for esophageal reconstruction after local radiation had led to benign stricture of his esophagus and subsequent development of a large, draining esophagocutaneous fistula. A gastro-omental free flap reconstruction of the esophagus and overlying skin defect was complicated by the intraoperative diagnosis of gastric carcinoid obtained from several polyps noticed on the gastric mucosa on routine inspection. This case report signifies the importance of close inspection of all free tissue transfers before interposition. Failure to do so could result in disastrous outcomes.

4/31. Pharyngoesophageal pressure in patients with swallowing disorders.

    We developed and tested a pressure transducer to correctly determine swallowing pressure at different sites in the pharynx. In normal individuals three pressure peaks were obtained in the mesopharynx, hypopharynx and cervical esophagus, respectively. A patient with central dysphagia demonstrated markedly low mesopharyngeal and hypopharyngeal swallowing pressure. One tongue cancer patient who had undergone right hemiglossectomy, including partial resection of the root of the tongue and bilateral superior neck dissection, had markedly low swallowing pressure in the mesopharynx and vallecula area. Another supraglottic cancer patient treated by supraglottic horizontal partial laryngectomy showed extremely low swallowing pressure in the supraglottic area. Based on our findings, we suggest that measurements using a pressure transducer such as the one described here should be used in combination with radiographic study to diagnose swallowing anomalies correctly. Data obtained with the pressure transducer will allow the clinician to identify the site responsible for postoperative dysphagia as well as its severity, and facilitate planning of reconstructive surgery when required.

5/31. An unusual case of dysphagia: retained Groningen valve.

    A Groningen speaking valve was lodged in the oesophagus in a post-laryngectomy patient and was neglected for nine years. The patient presented with dysphagia. It was diagnosed and removed on rigid endoscopy. The procedure was complicated by a primary tear of the oesophagus, that was managed conservatively. The case has many interesting features, that are discussed below.

7/31. Complication of esophageal self-dilation for radiation-induced hypopharyngeal stenosis.

    We present an unusual case of hypopharyngeal stenosis, secondary to radiation therapy for laryngeal squamous cell carcinoma, complicated by repeated inadvertent passage of a Maloney dilator through the larynx into the right mainstem bronchus during self-dilation. A brief review of esophageal/hypopharyngeal stenosis and management alternatives is presented. Self-dilation is presented as a therapeutic method for recurrent stenosis of the hypopharynx and esophagus. Recognition and avoidance of this complication is discussed.

8/31. myofibromatosis-like hemangiopericytoma metastasizing as differentiated vascular smooth-muscle and myosarcoma. Myopericytes as a subset of "myofibroblasts".

    A thyroid hemangiopericytoma that was resected in a 5-year-old boy recurred insidiously in the larynx 8 years later. Marked cicatricial mucosal inflammation prevented a definitive pathologic diagnosis of recurrence until a nodule grew to obstruct the airway 15 years after initial surgery. After excision of the nodule, a larger sarcomatous metastasis was discovered in the upper esophagus and resected, but the patient eventually succumbed to widespread disease at the age of 20 years. The original tumor contained atypical pericytes and bundles of hyalinizing smooth muscle abutting on "staghorn vessels," a pattern similar to infantile myofibromatosis. desmin immunostaining was negative in the pericytes but positive in smooth-muscle cells dispersed singly as well as in bundles. Both elements reacted strongly for vimentin and the alpha-isoform of actin (alpha-SMA) found in normal smooth muscle and pericytes. A third cell type showing dendritic processes and immunoreactivity for all three antigens was interpreted as a myopericyte. Spindled cells in multiple subsequent mucosal biopsy specimens stained retrospectively also positive for these antigens. Large bundles of vascular smooth muscle surrounded by radiating myocytes characterized the occluding laryngeal nodule. In the esophageal metastasis, which showed no histologic features typical of hemangiopericytoma, numerous mitotically active, small, vimentin , desmin , alpha-SMA cells often maintained shortened processes and tended to form nodular aggregates about capillaries. Single rows of pericytes accreted to endothelial tubes. Ultrastructurally, some cells contained myofilaments and irregular dense material or showed rare cell junctions and variable investment by a basal lamina.(ABSTRACT TRUNCATED AT 250 WORDS)

9/31. Lump sensation in the throat caused by tumors in the preepiglottic space.

    Lump sensation in the throat is a common symptom, which accounts for 4% of first patient visits to Otorhinolaryngologic clinics. The etiology includes abnormalities of the thyroid gland, cysts, tumors and chronic infections of the pharynx, larynx, esophagus and tongue base, gastroesophageal reflux and anxiety disorders. In this article we describe two rare cases of lump sensation caused by masses in the preepiglottic space and we stress the importance of thorough investigation to exclude any possible non functional causes.

10/31. Panendoscopy and synchronous second primary tumors in head and neck cancer patients.

    endoscopy techniques are used to diagnose and to determine the extent and exact location of malignancies in the head and neck region, bronchial tree and esophagus. Panendoscopy is used to find the primary tumor in the case of metastatic disease from unknown primaries or to detect a simultaneous second primary tumor at the time of diagnosis of a malignancy in the upper aerodigestive tract (UADT). The value of panendoscopy has been debated lately because of the relatively small proportion of malignant findings and because of the lack of convincing data concerning its effect on survival rates. However, despite the relatively low proportion of positive findings, their significance is often crucial for the individual patient. The significant number of late metachronous, second primaries, especially in the lungs, also emphasizes the importance of follow-up endoscopies. This study consists of 203 consecutive patients with squamous cell cancer (SCC) of the upper aerodigestive tract who underwent panendoscopy in Turku University Central Hospital as part of the initial diagnostic workup from 1992-1999. Eight patients with synchronous second primaries were found to represent a prevalence of 3.9%, and in addition, 19 patients with metachronous tumors were diagnosed. In the case reports we illustrate the importance of some of these findings.
