Benign tumors of the esophagus are rare and require an alert suspicion for early diagnosis. These tumors may not cause symtoms before attaining large size, yet they may prove fatal when small. Because of the possibility of malignancy and their tendency to obstruct, benign tumors of the esophagus should be resected when diagnosed. This report details our experience in 20 patients with benign esophageal tumors seen at Emory University Hospital between 1955 and 1975. There were 15 men and five women in the group, ranging in age from 17 to 75 years. The tumor series included 13 leiomyomas, four cysts, two cases of multiple polyps, and one case of granular cell myoblastoma. Six of the tumors were asymptomatic; the remaining 14 had symptoms of dysphagia, pain, and hematemesis. In one instance, episodic hematemesis and melena were so severe that they produced hemorrhagic shock. Characteristic radiologic features helped in making the preoperative diagnosis in 18 of the 20 cases. Two patients had coexisting disease masking the presence of the esophageal tumor. Seventeen patients had surgical resection. There were no operative deaths and follow-up results have been satisfactory.

Granular cell myoblastomas are uncommon, typically benign tumors. Involvement of the esophagus is rare, and frequently they are asymptomatic. We report a granular cell myoblastoma involving the cervical esophagus in a patient who had paralysis of the true vocal cord and progressive dysphagia. At MR imaging, the circumscribed mass was hypointense on T1-weighted images and mildly hyperintense on T2-weighted images, with homogeneous contrast enhancement.

Granular cell tumour (GCT) is a benign tumour with abundant eosinophilic cytoplasm filled with granules of varying sizes. These granules are the defining characteristic of the GCT and are believed to represent lysosomes in varying stages of fragmentation. The commonly used term granular cell myoblastoma, found in the older literature, is a misnomer because the tumour is clearly not of muscle origin. Among the major theories of origin, some support the tumour's derivation from neuronal tissue, histiocytes, fibroblast or Schwann cells. In the larynx, pseudoepitheliomatous hyperplasia may predispose to confuse the GCT with squamous cell carcinoma. The most common region of GCT is in the head and neck, accounting for approximately 30 to 50 per cent of all lesions. The larynx is relatively an uncommon location for these tumours, accounting for approximately three to 10 per cent of the reported cases. Affected patients typically present with persistent hoarseness, stridor, haemoptysis, dysphagia, and otalgia, but the tumour may be asymptomatic and be discovered only incidentally during a routine examination. Complete excision with an attempt to maintain normal structures generally results in cure. We present the case of a patient with typical features of a GCT of the larynx. The gross appearance, histopathology and brief discussion of the current literature are also presented.

A granular cell tumor (GCT; myoblastoma) was diagnosed on the tongue of a 12-year-old English Pointer with clinical signs of mild oral dysphagia. The diagnosis was confirmed by histopathologic examination and immunohistochemistry. The tumor was positive for S-100 protein, but also was positive for desmin, and was only weakly positive for PAS, which is unusual for GCTs. An epithelioid type of leiomyoma (leiomyoblastoma) was considered less likely on the basis of negative staining for smooth muscle actin. Treatment consisted of surgical resection of the tumor. The animal was in excellent clinical condition 1 year after surgery. Although GCT of the tongue has been reported previously in the dog, determining the cell of origin is still problematic. Immunohistochemistry is helpful for histogenetic classification and necessary for differentiation from leiomyoblastoma.
