Abstract:HighlightsExtracutaneous glomus tumors occurring in the bronchus is very rare.Two term resections enabled us to make an accurate diagnosis and evaluation.After bronchoscopic treatment, curative pulmonary resection was performed and preservation of lung function was successful.
“…5 ] [ 2 , 12 ]. The pathologic proliferation of the glomus cells either due to an underlying hamartoma or as a reaction to previous trauma may lead to GT formation [ 13 ]. Fig.…”
Background
Glomus tumor is an uncommon soft tissue tumor. However, as the tumor causes significant disability, its early diagnosis is essential. It involves subungual areas of fingers and toes in most cases, and its extra-digital involvement is rarely seen. To the best of the authors' knowledge, only a few chest wall involvement cases have been reported in the literature.
Case presentation
In this paper, we describe a 63-year-old patient with a chest wall glomus tumor presenting with axillary paroxysmal pain and limitation in his shoulder range of motion that had been missed for nearly 15 years. His symptoms were relieved immediately following surgical excision.
Conclusion
Glomus tumors may involve any part of the human body. It is curable with surgical excision in most cases. Therefore, a correct early diagnosis has paramount importance. A high index of suspicion is needed for early diagnosis, especially when the tumor involves uncommon anatomic areas.

“…The ideal management of tracheobronchial GT remains unclear[ 3 ]. In general, surgery may be the first choice for treating GTs that cause life-threatening airway obstruction and bleeding[ 15 ]. When the tumor arises from a lobar bronchus involving the origin or the main bronchus intraoperatively, a bronchoplastic procedure is needed[ 16 ].…”
BACKGROUND
Glomus tumors (GTs), defined by modified smooth cells and normal glomus body cells, usually present with a small mass occurring in the soft tissue or dermis of an extremity, especially in the subungual region. However, other unusual sites, such as the respiratory tract, have also been reported. They are usually sporadic. Their imaging findings are usually nonspecific and likely to appear as a well-delineated round mass that usually lacks calcification. To our knowledge, we report the first case of bronchial GTs with calcification, reminding clinicians and radiologists that GT is one of the differential diagnoses when a calcified nodular mass is found.
CASE SUMMARY
We report a case of a 33-yr-old Chinese man with cough and sputum for 11 d and hemoptysis for 5 d. Chest computed tomography revealed a calcified nodular lesion on the compressed posterior wall of the lower left main bronchus and bronchiectasis in the lower lobe of the left lung. To confirm the characteristics of calcified nodules, we performed fiberoptic bronchoscopy. The tumor tissue from the biopsy of bronchial mucosal lesions established the diagnosis of GT. Because the patient had no life-threatening symptoms, he was not treated with surgery. Clinical follow-up for 25 mo showed that the patient survived well without any discomfort.
CONCLUSION
Bronchial GTs are usually not accompanied by calcification on computed tomography scans. To our knowledge, we report the first calcified bronchial GT. We recommend that clinicians consider GT as a possible differential diagnosis when a calcified mass of the bronchi is found.
