Primary intra-abdominal synovial sarcoma.

We report a case of primary intra-abdominal synovial sarcoma of the omentum in a 66-year-old man hospitalized for intermittent abdominal fullness for 1-2 months and tenesmus for 2 weeks. The patient had a palpable mass that was solid, hard and with well-defined thickness within his abdomen. A huge heterogeneous mass lesion over the middle abdomen that started from S2, S3 of the liver to the transverse colon was shown on abdominal computed tomography. The major cell types of the tissue mass were confirmed to be spindle and epithelial cells, which was consistent with biphasic synovial sarcoma according to pathologic and immunohistochemical findings.

Spontaneous pneumothorax after steroid treatment in a patient with bronchiolitis obliterans organizing pneumonia.

Bronchiolitis obliterans organizing pneumonia (BOOP) is an uncommon pulmonary disorder which is a clinicopathologic syndrome. The typical symptoms include cough, fever and dyspnea. Corticosteroid therapy is effective. Death from progressive disease is infrequent. We report a case of BOOP in a 41-year-old male non-smoker, proved by pathologic findings. After steroid therapy (prednisolone 30 mg daily) for 10 days, he developed spontaneous pneumothorax of bilateral lung fields. Responses to steroid and chest tube thoracostomy were excellent. BOOP may be complicated with spontaneous pneumothorax which may adversely affect prognosis. BOOP should be included in the differential diagnosis of patients presenting with secondary spontaneous pneumothorax.

Glomus tumor of the trachea.

Glomus tumor of the trachea is extremely rare. There were approximately 15 reported cases before. Herein, we report another case of glomus tumor of the trachea in a 50-year-old woman presenting with cough and dyspnea for 8 years. She suffered from hemoptysis for 1 day before this admission. Bronchoscopy and CT scan showed a polypoid tumor protruding into the tracheal lumen and with extraluminal extension. The tumor was located at 9 cm below the vocal cord and 1.5 cm above the carina. It measured 2.5 x 2.5 x 2.0 cm and arose from the posterior wall of the trachea. Microscopically, the tumor consisted of a sheet of uniform cells surrounding the vascular spaces. Only few scattered tumor cells showed weak positive staining for muscle actin (HHF-35) by immunohistochemical stain. Ultrastructural study confirmed the presence of small amount of myofibrillar bundles with focal densities in some of the tumor cells. Other cells exhibited only rare or very sparse myofilaments. Characteristic feature of fine pinocytotic vesicles along the plasma membrance of the tumor cells was also noted.
