1/23. Multifocal granular cell tumor of the esophagus and proximal stomach with infiltrative pattern: a case report and review of the literature.

    The granular cell tumor is a solitary painless nodule that arises most commonly on the skin or the tongue. The vast majority are benign. Approximately 5% to 9% of granular cell tumors have been reported in the gastrointestinal tract, most commonly in the esophagus. We report a case of a 45-year-old African American woman with multifocal granular cell tumors of the esophagus and proximal stomach. Two lesions within the distal esophagus and proximal stomach were characteristic nodular granular cell tumors. Within the mid esophagus there was poorly defined transmural involvement by benign-appearing granular cells. This pattern of infiltration by benign cells is uncharacteristic. A review of the literature with emphasis on the determination of malignancy is also presented.

2/23. Granular cell tumour of the oesophagus: a rare cause of dysphagia with differential diagnosis of oesophageal neoplastic lesions.

    Granular cell tumour is a relatively uncommon, typically benign neoplasm of soft tissue. The macroscopic appearance of oesophageal granular cell tumour is a polypoid lesion, which is often asymptomatic and can be found incidentally, but, in some cases, is symptomatic and requires a correct differential diagnosis with malignant neoplasms of the oesophagus. We describe the case of a 28-year-old female who came to our attention due to a six-month history of heartburn and dysphagia. Oesophagogastroduodenoscopy showed the presence of a polypoid lesion 2 cm above the gastro-oesophageal junction. The overlying mucosa was normal and the lesion seemed to be an isolated submucosal nodule with a "submucosal pill" appearance. It was excised completely using a standard diathermic snare, and diagnosis of oesophageal granular cell tumour was made by histological and immunohistochemical staining. The patient's symptoms disappeared immediately after removal of the nodule by endoscopic polypectomy, and no macroscopic or microscopic recurrence of granular cell tumour was noted during follow-up. Likewise, the patient was symptom-free during follow-up. This case shows that endoscopy is very effective, not only in the diagnosis, but also in the treatment of oesophageal lesions which require careful differential diagnosis.

3/23. association of multiple granular cell tumors and squamous carcinoma of the esophagus: case report and review of the literature.

    This report describes the case of a man who underwent subtotal esophagectomy for the concomitant presence of a multifocal esophageal squamous carcinoma and a granular cell tumor (GCT); he had been previously affected by another metachronous esophageal GCT excised endoscopically. This is the sixth case described in the literature detailing other cases of a combination of malignancies involving additional organs. We emphasize the need for a prolonged surveillance of patients with multiple GCTs in order to promptly recognize the possibility of associated neoplasms.

4/23. Endoscopic treatment of benign esophageal tumors: case report of three patients.

    Benign esophageal tumors are rare. Enucleation of the tumor is considered when the patient reports problems. The traditional approach is to use thoracotomy or laparotomy if the tumor is located in the distal esophagus. The use of minimally invasive techniques permits enucleation with all the concomitant advantages. Our experience with the minimally invasive management of three benign esophageal tumors is described. The methods and results of preoperative studies are reported. The surgical technique is described. Two patients could be managed using thoracoscopy, and one patient required conversion to laparoscopy. All the patients had complete and quick recoveries.

5/23. Multiple synchronous granular cell tumours of the esophagus: a case report.

    Granular cell tumours (GCTs) are relatively uncommon, usually benign and solitary neoplasms. Approximately 5-11% of all tumours occur in the gastrointestinal tract and about one third of them appear in the esophagus. Till now, only 30 cases of multiple esophageal GCTs have been reported in the literature. We present the case of a 44-year-old man with three synchronous GCTs in the distal esophagus. The lesions were detected incidentally during esophagoscopy. Histopathologic examination of tissue samples revealed the nests of polygonal cells with small hyperchromatic nuclei and abundant granular cytoplasm located in the lamina propria of the mucosa. The cytoplasmic granules were positively stained with PAS and were diastase resistant. The positive immunostaining for S-100 protein was also noted.

6/23. Coexistence of esophageal granular cell tumor and squamous cell carcinoma: a case report.

    Granular cell tumors (GCTs) are relatively uncommon, usually benign and solitary neoplasms. Until now, about 200 cases of esophageal GCTs have been reported in the literature. We present a rare case of synchronous occurrence of esophageal GCT and moderately differentiated squamous cell carcinoma in a 40-year-old white woman. The GCT was detected incidentally during esophagoscopy undertaken for evaluation of a 4-month history of progressive solid food dysphagia. The gross and microscopic appearance of the GCT was typical. It was localized in the mucosa of the middle esophagus dystally and separately to the cancer. It revealed strong positive immunostaining for vimentin, S-100 protein and neuron-specific enolase, as well as weakly positive focal staining for Ki67 and p53 protein. Although, the coexistence of esophageal GCTs and cancers seems to be coincidental, the necessity of a careful clinical evaluation and a close follow-up of patients with GCT is suggested.

7/23. Multiple granular cell tumors of the gastrointestinal tract with subsequent development of esophageal squamous carcinoma.

    A 52-year-old woman initially presented to our medical center with synchronous, submucosal tumors of the esophagus, stomach, and transverse colon. The gastric and colonic tumors were resected, and both displayed infiltrating sheets of polygonal cells with coarsely granular cytoplasm and small vesicular nuclei. The neoplastic cells of both tumors were immunoreactive for S-100 protein. Ultrastructural studies revealed the lysosomal nature of the cytoplasmic granules. Although the esophageal mass was not resected, it was felt that this represented another focus of granular cell tumor of the gastrointestinal tract. Two years later, she presented with disseminated squamous carcinoma of the esophagus. At autopsy, a submucosal granular cell tumor was found adjacent to the squamous carcinoma of the esophagus. To our knowledge, this is the first reported case of synchronous granular cell tumors that involved multiple segments of the gastrointestinal tract, one of which was later associated with a squamous carcinoma of the esophagus.

8/23. Multiple esophagogastric granular cell tumors.

    Multiple granular cell tumors of the esophagus and the stomach found in a 53-year-old man are reported. One lesion was detected within the lower thoracic esophagus and seven lesions were detected in the stomach. The esophageal tumor was resected endoscopically, and gastrectomy was performed for the multiple gastric lesions. Histologically, the tumors consisted of spindle or polyhedral cells and the cytoplasm contained punctated eosinophilic granules with positive immunohistochemical staining for S-100 protein. The tumors were mainly located in the submucosal layer. Some tumor cells were seen in the mucosae propria and the muscularis propria. The tumor cells were only slightly positive for p53- and Ki-67-immunohistochemical stainings. Based on these findings, we diagnosed the granular cell tumors as benign. granular cell tumor is comparatively rare in clinical practice, but a few such tumors have been seen in the digestive tract. A few cases of multiple esophagogastric granular cell tumors have also been reported in the literature.

9/23. Endoscopic finding of granular cell tumour associated with leiomyomas in the oesophagus.

    Following a single report in the literature of granular cell tumour associated with diffuse leiomyomatosis in the oesophagus, we describe the case of a 39-year-old man in whom a granular cell tumour and two leiomyomas were endoscopically removed from this site. This previously unreported association of granular cell tumour with isolated leiomyomas suggests the need to bear in mind the possibility of other mesenchymal lesions, including leiomyomas or leiomyomatosis, when a granular cell tumour is found in the oesophagus.

10/23. Treatment of granular cell tumor of the esophagus by endoscopic injection of dehydrated alcohol.

    granular cell tumor of the esophagus (GCTE) is a rare and mostly benign neoplasm. Its etiology is unknown and its histogenesis is uncertain. It is usually an incidental finding, detected during esophagogastroduodenoscopy. In symptomatic cases, or when the lesions are more than 1 cm in diameter, the treatment of choice has been local resection. Asymptomatic patients or tumors smaller than 1 cm are followed endoscopically. We describe a case of GCTE successfully treated by endoscopic injection of dehydrated ethyl alcohol. To our knowledge, it is the first time that such a tumor was treated by this accessible and low-cost technique.
