P3.01-007 - A Pulmonary Glomus Timor (ID 4474)
14:30 - 14:30 | Author(s): T. Maekawa
- Abstract
Background:
Glomus Tumor is almost a benign tumor that often develops in the nail bed of the extremities, and accounts for 1.6% of all soft tissue tumors. However, they developed in the other organs, such as gastrointestinal, bone, adrenal gland, central nerve system, uterus and vagina. We here reported a rare case of a pulmonary glomus tumor with some literature.
Methods:
Case A 36–year–old female was admitted to our hospital with an abnormal shadow in the left lung field. She has no major disease, and nonsmoker. The laboratory data and physical examination are normal. A chest computed tomography scan showed a nodal lesion of 1.0 cm in diameter in the left lower lobe. Thoracoscopic partial resection was performed.
Results:
The tumor was well-circumscribed lesion consists of solid sheets of tumor cells interrupted by capillaries and vessels of varying sizes in the pulmonary tissue. In the pathological findings, the tumor cells have relatively uniform, rounded to oval nuclei, indistinct nucleoli, and ill-defined cytoplasmic borders. In the immunohistochemical examination, the tumor cells were positive for αSMA, HHF-35, desmin and vimentin, but negative for EMA, cytokeratinAE1/AE3, TTF-1, surfactant apoproteinA, CD34 and Factor VIII. Some tumor cells were positive for Ki-67. Those features were consistent with pulmonary glomus tumor.
Conclusion:
Glomus tumor of the lung is rare tumor and only a few cases have been reported in the literature. The behavior of this neoplasm is uncertain, so the methods of diagnosis and treatment, includes of surgical approach will demand to do careful observation and further examination.

P3.04-028 - The Left Upper Division Sacrifice for Bronchoplasty for an Adenoid Cystic Carcinoma of the Left Main Bronchus (ID 4306)
14:30 - 14:30 | Author(s): T. Maekawa
- Abstract
Background:
The adenoid cystic carcinoma is sometimes growth in the upper airway. Main treatment for the disease is included operative resection and radiotherapy. The operative resection often needs air way reconstruction. We performed bronchoplasty and additional left upper division lung segmentectomy for the anastomotic tension reduce for an adenoid cystic carcinoma patient of the left main bronchus.
Methods:63 year-old male with severe Diabetes mellitus (HgbA1c level=10.4) was admitted to our hospital because of cough and sputum. Bronchoscopic examination showed a tumor of the left main bronchus, and pathologic examination of transbronchial biopsy revealed adenoid cystic carcinoma. We performed 6 rings of the left main bronchial cartilage resection and bronchoplasty, and additionally, the left upper division segmentectomy were performed for reduction of the bronchial anastomotic tension. The bronchoplastic site was covered with the left thymic lobe between the left main pulmonary artery.
Results:
There was no severe complication after the operation. The pathological examination showed the no regional lymph node metastasis, however, the microscopic tumor positive of the both side bronchial stump. On the 48th day after the operation, he was applied of 60 Gy radioactive rays for the left main bronchus. On the 28 months after the operation, he is well without any tumor recurrence.
Conclusion:
We successfully performed the left main bronchoplasty for adenoid cystic carcinoma patient with severe Diabetes mellitus. The left upper division segmentectomy was useful for tension reduce of the bronchoplastic anastomosis.
