Synchronous multiple glomus tumors of the esophagus and lung.
ABSTRACT A case of synchronous esophageal and multiple pulmonary tumors presenting complex diagnostic problems is described. In the course of routine pulmonary screening a pulmonary coin lesion of the right lung and three very small foci on the left side, under the pleura falling just within the range of diagnostic parameters was identified in a symptom-free patient. In addition to the multiple lung lesions a single sub-mucosal esophageal tumor was detected. Following minimally invasive surgical excision of the tumors the precise nature of the neoplasms was determined by means of comparative histological, light-and electro-microscopic as well as immunohistochemical studies. The earlier diagnosis of carcinoid was reviewed, rejected and glomus tumor was confirmed. Multiple glomus tumors of the above localizations have not been previously described in the literature.

ABSTRACT: Here we report a case of primary glomus tumor of the esophagus, which is extremely rare, and review the corresponding literature. A 69-year-old man underwent screening endoscopy during a medical checkup and a submucosal tumor was incidentally found in the midthoracic esophagus. Endoscopic ultrasonography revealed that the tumor originated from the muscle layer of the esophagus. Computed tomography and 18F-fluorodeoxyglucose positron emission tomography revealed neither lymphadenopathy nor distant metastasis. Endoscopic ultrasonography-guided fine needle aspiration biopsy indicated epithelioid mesenchymal tumor. Immunohistochemically, the tumor cells were positive for alpha smooth muscle actin, and focally positive for Discovered on GIST1 but negative for c-kit and protein kinase C theta, suggesting that the lesion was a KIT-negative epithelioid gastrointestinal stromal tumor or glomus tumor. The tumor was successfully enucleated through right thoracotomy. Pathological examination confirmed that the tumor was a glomus tumor of the esophagus. The patient remains healthy without any recurrence to date one year after surgery.Esophagus 03/2012; 10(1). DOI:10.1007/s10388-012-0345-5 · 0.74 Impact Factor
