Esophageal carcinosarcoma is a rare malignant tumor. The tumor is composed of both carcinomatous and sarcomatous elements. The multiple designations of names such as pseudosarcoma, pseudosarcomatous carcinoma, polypoid carcinoma etc. reflect the controversy on the nature of sarcomatous component of this lesion. We report a case of carcinosarcoma of esophagus occurred in a 67 year old male with progressive dysphagia. Esophageal polypoid tumor was found by endoscopy and was resected by esophagectomy. Carcinosarcoma was proved by demonstrating both carcinomatous and sarcomatous components in the tumor. Immunohistochemical studies revealed positive keratin stain in the sarcomatous area and positive vimentin stain in the sarcomatous area. The tumor was reported to have a better prognosis than that of the squamous cell carcinoma of esophagus in the literatures, especially in the survival rate.

To overcome the drawbacks of the modified Gianturco stent tube with barbs, a new barbless stent tube was constructed. Twenty-two barbless stent tubes 4.5-14.0 cm long were placed with a new introducing tube in 21 patients: 10 stent tubes in 10 patients with recurrent dysphagia after radiation therapy or chemotherapy, 10 in 10 patients with esophageal cancer in whom surgical management was contraindicated, and two in one patient with postoperative benign stricture. No technical failure or procedural complications occurred. After the procedure, all but two patients could ingest most or all foods. In two patients with an esophagorespiratory fistula and one patient with esophageal rupture, the barbless stent tube successfully occluded the fistula and rupture site. The stent tube migrated in one patient. Fifteen patients are surviving, with the stent tubes patent for 3-35 weeks (mean patency, 13 weeks); the six other patients died 7-24 weeks (mean, 16 weeks) after stent placement. It is concluded that barbless stent tubes show promise in the management of dysphagia caused by esophageal strictures.

We describe the unique clinical and histopathologic features of a child with biochemical and immunocytochemical features of Niemann-Pick disease type C (NPC). Clinically, she was found to have multiple xanthomas of the upper aerodigestive tract with dysphagia and expressive language delay, splenomegaly, bony infarcts, and type IIb hyperlipidemia. Neurologic examination was otherwise normal. Microscopy revealed foam cells in her bone marrow, liver, tongue, tonsils, glottis, and in normal-appearing peritonsillar mucosa. Lipid analysis of a liver biopsy specimen showed a small increase in phospholipids, a twofold increase in sphingomyelin, a fivefold increase in cholesterol, and a marked (25-fold) increase in bis(monoacylglycerol) phosphate. Lysosomal acid hydrolase activities in cultured skin fibroblasts were nondiagnostic. Biochemical and immunocytochemical studies of cultured fibroblasts demonstrated lysosomal accumulation of unesterified LDL-derived cholesterol as well as delayed induction of homeostatic responses to endogenous cholesterol consistent with a diagnosis of NPC. Based upon these observations, we speculate that this patient could have a new phenotypic expression of NPC or represents a new cholesterol lipidosis biochemically resembling NPC. The chance occurrence of two separate lipid disorders seems less likely.

Croup is a common childhood disease that has no specific diagnostic test. It must be differentiated from life-threatening diseases, such as epiglottitis, that demand specific interventions. A high degree of toxicity, the presence of dysphagia and the absence of cough help distinguish epiglottitis from croup. The usefulness and safety of visualization of the epiglottis in patients with croup are controversial. Clinical recognition of respiratory distress and failure is vital. Hypoxia is common. Pulse oximetry is helpful in the assessment of hypoxia, but readings do not correlate with clinical status or respiratory failure. Although studies have not proved that mist therapy is beneficial, the efficacy of racemic epinephrine is well documented. High dose corticosteroids have proved effective in the treatment of croup. Outpatient use of racemic epinephrine and steroids remains controversial.

Although a rare entity, laryngeal tuberculosis must be a diagnostic consideration--along with laryngeal carcinoma--whenever patients present with prolonged hoarseness or painful dysphagia. This form of tuberculosis was once thought to be especially virulent and more infectious than other forms; however, severity was probably the result of the frequent association with advanced cavitary disease. Laryngeal tuberculosis usually responds well to multiple-drug antituberculous therapy.

One hundred eleven patients who underwent esophagectomy for squamous carcinoma of the esophagus were followed up during a 42-month period. Forty-three patients who had normal swallowing in the postoperative period had recurrent dysphagia on follow-up. The causes were benign anastomotic stricture (n = 15), malignant anastomotic recurrence (n = 2), recurrent laryngeal nerve palsy (n = 22), and no known cause (n = 4). Twenty-six patients were assessed by laryngoscopy and 15 were deemed suitable for Teflon injection of the vocal cord. All but one patient had improved swallowing and phonation after the procedure. Mean survival time after Teflon injection was 5 1/2 months. A significant proportion of swallowing problems after esophagectomy are not caused by mechanical obstruction. Teflon injection of a unilateral paralyzed vocal cord provides good palliation in these patients.

Esophageal perforation is the most serious perforation of the gastrointestinal tract, and despite early diagnosis and treatment, mortality remains high. Twenty-four cases of esophageal perforation seen at a large multispecialty clinic between 1983 and 1991 were retrospectively reviewed. Thirteen patients presented with acute perforation, five with subacute, and six with chronic perforation. Eighteen (75%) of 24 perforations resulted from iatrogenic causes, and the rest were spontaneous. Of the iatrogenic perforations, therapeutic endoscopy and paraesophageal surgical complications were responsible for 55% and 33%, respectively. Chest pain, fever, and dyspnea were common presenting signs and symptoms of acute perforation, whereas dysphagia and supraventricular arrhythmia were more prominent features of chronic perforation. All but seven patients had surgical intervention. An overall mortality rate of 46% was noted, and despite early diagnosis and treatment, this mortality was associated with the severity of underlying disease.

We have reviewed 28 esophageal biopsies from 28 patients with the acquired immune deficiency syndrome (AIDS), over a 1-yr period. Indications for esophageal biopsy were dysphagia persisting after antifungal therapy and/or radiologic evidence of esophageal ulcer. We compared the frequency of detecting cytomegalovirus (CMV) infection on hematoxylin and eosin (H&E) stain with immunoperoxidase staining for CMV antigens. Five biopsies were positive for CMV by H&E stain and immunoperoxidase. Infected cells could often be identified in the granulation tissue and, in one severe case, in stromal papillae of the intact mucosa. Squamous cells were never positive. Thirteen biopsies consisted only of squamous epithelium, and all of these were negative by both techniques. Among the remaining 10 cases, no CMV inclusions were identified by H&E. Three of these biopsies displayed staining for viral antigens. In all cases positive by immunoperoxidase, numerous cells positive for viral antigens did not display any of the CMV-specific morphologic diagnostic criteria. Other coexisting diagnoses included candidiasis, Kaposi's sarcoma, and malignant lymphoma. We conclude 1) CMV infection of the esophagus is common in AIDS patients with esophageal ulcer or esophagitis resistant to antifungal therapy; 2) multiple infections or neoplasms may coexist; 3) since CMV apparently does not infect squamous epithelium and only rarely endothelium in stromal papillae, deep biopsies are necessary for diagnosis; and 4) immunoperoxidase staining is required for maximum diagnostic yield.

Twenty-five patients with oropharyngeal dysphagia due to a variety of disorders (4 with muscular dystrophy, 4 with myasthenia gravis and 13 with inflammatory myopathies) were studied clinically by esophageal manometry and isotopic clearance. Clinically patients had moderate dysphagia and 45% other symptoms such as nasal regurgitation, bronchial aspiration, etc. The most important manometric abnormality was the feeble contractions of the pharyngeal musculature, more pronounced in patients with severe dysphagia (grade II). Isotopic clearance of the oropharynx showed slowing of the pharyngeal emptying curve and an increased residual activity in this area. Isotopic oropharyngeal clearance is a useful, comfortable and noninvasive test for determining the clinical improvement which accompanies the manometric recovery of the pharyngeal muscular contraction.

The clinical manifestations, pathology and surgical treatment of 10 cases of primary esophageal small cell carcinoma were presented with a detailed review of literature. The 10 cases accounted for 0.7% of all esophageal carcinomas treated surgically in the same period. The major symptom was dysphagia. 50% were of exophytic type grossly (fungating or intraluminal). The microscopic findings were not different from those of small cell lung cancer. All of these 10 cases had their cancer radically resected. The one and two year survival rates were 50% and 25%, respectively. The median survival time was 15.2 months. Case 2 has been living tumor-free for 48 months. The results of surgical treatment of this rare type esophageal carcinoma was poor as compared to that of squamous cell carcinoma of the esophagus.
