[Segmentectomy for Congenital Left Upper Lobar Bronchial Atresia].

A 22-year-old woman visited a hospital to treat her dyspnea which had lasted for some months. Chest X-ray showed hyperlucency in her left upper lung field and chest computed tomography suggested left upper bronchial obstruction with mucoid impaction. She was referred to our hospital for further examination and treatment.

[Ectopic Hilar Thymoma Associated with Morvan Syndrome after Extended Thymectomy for Myasthenia Gravis].

Morvan syndrome is a rare autoimmune neurological disease characterized by peripheral nerve hyperexcitability, autonomic dysfunction and encephalopathy.

A 61-year-old man had been diagnosed as lung cancer (cT4N2M0, stage IIIB) and radiochemotherapy was performed. After the treatment, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was done to identify the histrogical type and to detect the oncogenic driver mutation. After EBUS-TBNA, he developed a high grade fever and the findings of the chest computed tomography (CT) suggested the infection of puncture site in mediastinum.

[Subpectoral lipoma developing to cervix; report of a case].

A 54-year-old Japanese female, who presented slight swelling of the supraclavicular region due to soft indolent mass without neurological impairment, was admitted to our hospital to receive surgical treatment. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed subpectoral mass surrounded by the minor pectoral muscle, the subscaplar muscle, and the bony thorax, and spread to cervix passing through between the right clavicle and the bony thorax, indicating similarity of the intensity and the density to subcutaneous fatty tissue, and then the mass was guessed to be extremely rare subpectoral lipoma. The lipoma was dissected successfully from adjacent subclavian artery and vein, brachial nerve, and surrounding muscles through sub-and supra-clavicular small skin incision without cut of the clavicle.
