Five patients with polypoid esophageal sarcoma are reported. All had dysphagia similar to that occurring in epithelial carcinoma of the esophagus. The clinical diagnosis of sarcoma was suspected when barium swallow showed a large polypoid lesion. Biopsy was often inconclusive concerning the nature of the lesion except to identify it as a neoplastic process. In spite of their large size, the tumors remained superficial within the esophageal wall. Nodal or distant organ metastasis was absent in 4 of the 5 patients. The histology of these tumors suggests that so-called carcinosarcoma is an epithelial carcinoma of the esophagus with varying amounts of spindle cell features and should be considered separately from sarcoma arising from mesenchymal tissue. Unlike carcinoma, esophageal sarcoma has a favorable prognosis following radical resection, and recent advances in esophageal surgery have decreased the mortality and morbidity of esophagectomy.

Primary noncarcinomatous malignant neoplasms of the esophagus are uncommon and data concerning treatment and results are sparse. To evaluate the results of therapy in this group, we reviewed the records of 32 patients with primary esophageal malignant tumors of unusual histologic type. Thirteen patients (41%) had sarcoma, eight (25%) melanoma, and 11 (34%) had oat cell carcinoma. Dysphagia was present in 78% (25/32) of the patients for a median of 13 weeks before diagnosis. Location of the esophageal primary tumor was upper third in four patients (12%), middle third in 12 (38%), and lower third in 16 (50%). Treatment consisted of esophagectomy in 10 of 13 patients with sarcoma (77%), seven of eight with melanoma (88%), and three of 11 with oat cell carcinoma (27%). Patients not undergoing resection received chemotherapy or radiation therapy, or both. The 3- and 5-year survival rates were 46% and 23% for sarcoma (median 20 months), 13% and 0% for melanoma (median 5 months), and 0% and 0% for oat cell carcinoma (median 5 months), respectively. Distant disease was the initial form of recurrence in 73% (11/15) of patients undergoing curative therapy. Surgical resection appears indicated for localized primary esophageal sarcoma. Optimum treatment of primary esophageal melanoma is less clear, but surgical resection may be of benefit in selected patients. Esophageal oat cell carcinoma is a systemic disease necessitating systemic therapy with local therapy reserved for palliation of dysphagia.

Leiomyosarcoma of the esophagus is a rare neoplasm. We reported a very rare case of esophageal leiomyosarcoma associated with pulmonary edema by the compression of the left atrium. A 67-year-old man was admitted with a 3-month history of chest pain, exertional dyspnea and dysphagia. Chest X-ray computed tomography showed posterior mediastinal tumor. Esophageogastroscopy and fiberoptic bronchofiberscopy showed no direct invasion of the tumor. By echocardiography, the left atrium was found to be compressed by the tumor and pulmonary hypertension (58/25 mmHg) and increased pulmonary wedge pressure (25 mmHg) was present. Open biopsy specimen demonstrated elongated cells suggestive of sarcoma. At autopsy, the tumor was confirmed to be leiomyosarcoma and to be originated from the lower esophagus.

The purpose of the study reported in this article was to tabulate the incidence and etiologic factors of importance in the development of strictures after radiotherapy for carcinoma of the esophagus and to analyze the outcome of patients who develop such strictures. Eighty patients were treated with radiotherapy, 50 having radical and 30 having palliative treatment. Sixty-nine patients had squamous cell carcinoma, four had adenocarcinoma, one had sarcoma, one had mucoepidermoid carcinoma, and five had undifferentiated tumors. Forty percent developed no stricture, 30% had benign fibrotic stricture, and 28% developed malignant stricture. The etiologic factors analysed included age, pretreatment swallowing score, histology and length (size) of tumor; stage of disease, dose of radiotherapy, and use of chemotherapy. None of these factors were shown to be of etiologic importance. The survival of patients who developed benign strictures was found to be significantly longer (1-year survival 88%) than those who developed no stricture (50%) or malignant stricture (19%). Using a "success score" for palliation of dysphagia, it was found that the majority of patients (71%) who developed a benign stricture had a moderately successful outcome--they were able to tolerate a full or soft diet and required dilatation with a median duration between dilatations of 5 months. Patients who developed a malignant stricture were palliated poorly by dilatation alone, and most required esophageal intubation.

A 67-year-old male consulted an otolaryngologist with a complaint of dysphagia due to a large polypoid mass in the hypopharynx. A biopsy of the mass revealed immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma of helper/inducer subset occurring in lymphoid tissues of the hypopharynx. Although general lymphadenopathy was not seen, further biopsy of an inguinal lymph node showed small foci of lymphoma cells, suggesting the generalized distribution of this malignancy. To our knowledge, this is the first report of this malignancy mimicking primary pharyngeal sarcoma.

Involvement of the larynx by hemopoietic tumors is generally considered a rare event and little is known about the associated clinicopathologic features. Laryngeal tissue removed at autopsy from 14 patients with known disseminated hematologic malignancies and at operation from one patient with multicentric malignant lymphoma of low-grade malignancy (MALToma) of the head and neck region was investigated. A systematic survey of the main clinicopathologic features of the published cases of hemopoietic tumors with laryngeal involvement was also performed. Primary involvement of the larynx by hemopoietic neoplasms must be clearly distinguished from secondary involvement by disseminated or leukemic tumors. Most of the primary tumors are localized lesions that may involve the regional lymph nodes (stages IE or IIE). Radiotherapy is the treatment of choice, and the prognosis is generally favorable. However, secondary involvement by disseminated or leukemic disease carries a very poor prognosis in most cases. Extramedullary plasmacytoma and non-Hodgkin's lymphoma (NHL), particularly B-cell lymphoma of high-grade malignancy, appear to be the most common hemopoietic tumors with primary laryngeal involvement, while primary tumors of myelogenous origin (granulocytic sarcoma and mast cell sarcoma) are extremely rare. Extramedullary plasmacytoma and NHL occur mainly in older persons and in men, are generally associated with a relatively short history of hoarseness and dysphagia, and exhibit preferential involvement of the supraglottic parts of the larynx, in particular the epiglottis and aryepiglottic folds. They are generally polypoid, non-ulcerated lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

A 54-year-old man with a complaint of dysphagia was found to have a prominent stricture in the proximal esophagus. A biopsy of the stenotic area indicated sarcoma, leading to subtotal esophagectomy. The surgically removed esophagus demonstrated a well-defined intramural mass, consisting of a mixture of fibroblastic cells with bland cytological appearances and inflammatory cells. Reflux esophagitis which was present distal to the stricture seemed to play a role in the development of this inflammatory pseudotumor.

Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma of late adult life, but is relatively uncommon in the head and neck region. That region has been reported to be the origin of malignant fibrous histiocytoma in 3-10% of cases. Only one case of the tumor occurring in the pharynx has been reported. Histologically it is sometimes hard to distinguish this tumor from some sarcomas and pleomorphic carcinomas. The treatment of choice is a large surgical resection, while radiotherapy and chemotherapy are reserved for recurrences. The authors present a case of oropharyngeal malignant fibrous histiocytoma. The patient complained dysphagia and dyslalia progressively worsening in six months. Pharyngo-laryngoscopy revealed a mass of the left lateral wall of oro and hypopharynx. CT scan examination showed a capsuled mass which displaced but not involved the neck neurovascular structures; there was no evidence of linphonodal involvement. Transoral surgical excision of the mass was performed with the preservation of speech and swallowing. For more than 1 year postoperatively, there has been no evidence of the disease or metastasis.

A seven-year-old flat-coated retriever presented with a history of lethargy, dyspnoea and inappetence of several days' duration. Clinical examination revealed pale mucous membranes and tachypnoea, and haematology demonstrated marked autoagglutination. Thoracic radiographs revealed an increased opacity in the perihilar region. The owners declined further evaluation and the dog was treated symptomatically with immunosuppressive doses of prednisolone and azathioprine. The dog's demeanour improved, although it was eventually euthanased seven weeks later because of dysphagia and worsening dyspnoea. Postmortem examination revealed a widespread, poorly differentiated sarcoma involving the lungs, pericardium, thoracic lymph nodes and spleen. Immune-mediated haemolytic anaemia is a well recognised condition in dogs and is occasionally associated with neoplastic conditions. This is the first case report to describe immune-mediated haemolytic anaemia associated with a diffuse, poorly differentiated sarcoma.

A 46 year old male presented with progressively increasing dysphagia and weight loss. Esophagoscopy showed a large polypoidal growth involving the middle segment of esophagus. Histologically bulk of the tumour had a sarcoma-like appearance composed of spindly pleomorphic cells along with extensive areas of bone formation. The epithelial element was represented by a small area of squamous cell carcinoma. One of the draining lymph nodes also showed small islands of squamous cell carcinoma. A diagnosis of sarcomatoid carcinoma was made. Sarcomatoid carcinoma of the esophagus, also termed carcinosarcoma, pseudosarcoma, and spindle cell carcinoma is an unusual malignant tumour of the esophagus. The proportion of carcinomatous and sarcomatous component may vary from case to case. Rarely, the sarcomatous component may exhibit osseous differentiation as in our case.
