“…(2,4,7) In the previous reports, pulmonary resection was not necessary for the treatment of the endobronchial tumor. (1)(2)(3)(4)(5)(6)(7)(8) However, in the present case, the tumor had obstructed the right upper lobe bronchus for at least 9 months, leading to pulmonary infection and parenchymal destruction. These findings led us to proceed to a right upper lobectomy with wedge bronchoplasty in order to achieve tumorfree resection margins.…”

“…(2) They are presumed to originate from cells resembling the modified smooth muscle cells of the neuromyoarterial glomus or glomus body, which is a form of arteriovenous anastomosis thought to be associated with thermoregulation. (8) Although glomus tumors are most commonly located in the subungual region, other common sites include the palm, wrist, forearm and foot. However, in rare cases, these tumors are also found at sites where glomus bodies are sparse or even absent, such as the viscera.…”

“…(4) Several cases of glomus tumor arising from the trachea or the lung parenchyma have been reported. (5,(8)(9)(10) However, only nine cases of glomus tumor arising from the bronchus Radical mediastinal lymph node dissection was not performed. The patient had an uneventful recovery and was discharged on the fourth postoperative day.…”

physical examination revealed right-sided wheezing, and a chest X-ray showed right upper lobe atelectasis (Figure 1a). A chest CT scan revealed an endobronchial lesion occluding the right upper lobe bronchus (Figure 1b), with no mediastinal lymph node enlargement. Fiberoptic bronchoscopy revealed an endobronchial tumor located in the right upper lobe bronchus. The tumor had a smooth, reddish surface and had obstructed the right upper lobe bronchus, without protruding into the right main bronchus. A biopsy provided inconclusive results. The patient underwent right thoracotomy with a presumed diagnosis of carcinoid tumor. Since the right upper lobe was atelectatic and fibrotic, we proceeded to a right upper lobectomy. The intraoperative histological examination demonstrated exiguous bronchial margins, and a wedge bronchoplasty was therefore performed.

Intrathoracic glomus tumors and glomangiosarcomas: a clinicopathological and immunohistochemical study of 14 cases with emphasis on anatomic distribution

Fourteen cases of primary intrathoracic glomus tumor and glomangiosarcoma are presented. The patients were 9 men and 5 women aged 36 to 63 years (mean, 49.5 years). Clinically, 11 patients presented with nonspecific symptoms including cough, hemoptysis, chest pain, and back pain while 3 patients were asymptomatic. Anatomically, 9 tumors were in an intrapulmonary location, 3 in the mediastinum, and 2 in the trachea. Surgical resection was performed in all cases, and grossly the tumors varied in size from 1.5 to 4.5 cm in greatest diameter. Histologically, 12 cases corresponded to glomus tumor characterized by a homogenous proliferation of medium-sized cells with round nuclei and inconspicuous nucleoli and no evidence of mitotic activity or necrosis. In 2 cases, the presence of marked cellular pleomorphism, nuclear atypia, and mitotic activity was more in keeping with a diagnosis of glomangiosarcoma. The 2 glomangiosarcomas were located in the lung, one of which was associated with lymph node metastasis. Immunohistochemical stains for smooth muscle actin were positive in all cases while negative for epithelial, vascular, neuroendocrine, and neural markers. Clinical follow-up showed that all patients with a glomus tumor are alive and well after a period of 12 to 36 months after surgical resection. In contrast, the 2 patients with glomangiosarcoma died of tumor 24 and 36 months, respectively, after initial diagnosis. The current cases highlight the ubiquitous distribution of these tumors within the thoracic cavity and stress the importance of including these tumors in the differential diagnosis of thoracic neoplasms.
