VATS has been extensively considered as a standard method of pulmonary diagnosis and treatment of benign lung diseases. This study aimed to investigate the safety, efficacy, and feasibility of video-assisted thoracoscopic surgery (VATS) lobectomy compared with conventional lobectomy via open thoracotomy in patients with clinical early stage lung cancer. ⋯ Anatomical lobectomy was successfully completed by VATS lobectomy for lung cancer; the standard lymph node dissection was also achieved. This procedure also showed advantages in terms of surgical bleeding, duration, postoperative complications, indwelling time of chest tube, and short-term recurrence rate without significant differences from conventional lobectomy.

This study aimed at identifying risk factors of recurrence for completely resected pathologic T1aN0M0 lung adenocarcinomas. ⋯ Our results showed that the solid- and micropapillary predominant subtype of IASLC/ATS/ERS classification remains the only risk factor for post-operative recurrence of T1aN0M0 adenocarcinomas, suggesting that they can be indicators of aggressive tumor behaviors.

A new lung adenocarcinoma classification proposed by the International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) has recently been published. This study aimed to investigate the utility of the new histological classification for identifying the prognostic subtypes of adenocarcinomas in stage IB patients.Correlations between the classification and the presence of epidermal growth factor receptor (EGFR) mutation status was also studied. ⋯ The predominant subtype in the primary tumor was associated with prognosis in resected stage IB lung adenocarcinoma. The EGFR mutation frequency of micropapillary-predominant subtype is higher than other subtypes.

The authors report the case of 46-year-old man with recurrent hemoptysis. Bronchoscopy revealed a submucosal tumor protruding into the tracheal lumen. Transbronchial biopsy failed to obtain a conclusive diagnosis; only surgery allowed complete resection of the tumor and confirmed the diagnosis of tracheal mucoepidermoid carcinoma. We discuss the unusual submucosal presentation of this tumor, and the contribution of surgery for diagnosis and therapy.

Intracranial osteomas are uncommon lesions that usually arise from the inner table of the cranium. There are few reports in the literature of intracranial osteomas with meninges attachment and without direct relation with the skull bone; these osteomas were mostly attached with dura. We report a rare osteoma with falx attachment. ⋯ This is the first case report in the English literature of an intracranial osteoma arising from the falx. Because of their slow growth and their locations in silent brain areas, intracranial osteomas are usually diagnosed incidentally. Surgical resection is the primary treatment choice.
