We report a rare case of squamous cell carcinoma of the chest wall in a patient with chronic empyema. The patient was a 74-year-old male who had been treated by closed chest drainage for empyema for 20 years until the development of carcinoma. He received chest wall resection followed by radiation therapy because of disseminated lesions comfirmed at surgery. However, his condition worsened gradually, and he died 2 months postoperatively. In the treatment of chronic empyema, we must pay attention to the possible association of malignant tumor for treating as early as possible, because the associated malignant tumor usually has a poor prognosis.

Fungi and/or Staphylococcus aureus enterotoxins (SEs) may participate in the pathogenesis of eosinophilic inflammation in cases of chronic rhinosinusitis with nasal polyps (CRSwNP). Objective We sought to determine the effects of fungal antigens on eosinophilia-associated cellular responses in nasal polyps.Dispersed nasal polyp cells (DNPCs) were prepared from 13 patients with CRSwNP. DNPCs were cultured with fungal extracts (Aspergillus, Alternaria and Candida) or SEB for 72 h, after which the levels of IL-5, IL-13 and RANTES were measured within the supernatant. Responses to β-d-glucan, mannan and chitin were also examined.38.5%, 69.2% and 30.8% of DNPCs produced IL-5, IL-13 and RANTES, respectively, in response to 200 μg/mL of Aspergillus. 53.8%, 53.8% and 7.7% of DNPCs produced IL-5, IL-13 and RANTES, respectively, in response to 200 μg/mL of Alternaria. 53.8%, 38.5% and 15.4% of DNPCs produced IL-5, IL-13 and RANTES, respectively, in response to 200 μg/mL of Candida. All DNPCs produced these cytokines in response to 0.1 μg/mL of SEB. SEB induced significantly greater cytokine levels than the fungal extracts. No correlation between cytokine production following exposure to each of the fungal extracts or SEB and various clinical features, including nasal polyp eosinophilia and radiological severity of sinusitis was observed. Neither sensitization to fungus nor comorbidity with bronchial asthma was correlated with the fungal extract-induced cytokine production by DNPCs. β-d-glucan, mannan and chitin did not induce significant cytokine production.These results suggest that, although DNPCs produce IL-5, IL-13 and RANTES in response to fungal extracts, fungal antigens including major carbohydrates are less capable of inducing eosinophilia-associated cellular responses in nasal polyps than SEB.

A case of recurrent tuberculous abscess in the chest wall which was successfully treated by resection of the rib and transposition with a latissimus dorsi muscle flap is reported. A 70-year-old man was admitted to the hospital for the purpose of receiving tuberculostatic treatment after an operation for tuberculous abscess in the chest wall at another hospital. When he first visited the another hospital, he had complained of a left chest wall tumor and Mycobacterium tuberculosis was isolated from the pus. After admission to the hospital, tuberculous abscess recurrenced in the left chest wall 2 months after the operation. We performed resection of the abscess, 5th and 6th ribs, as well as transposition of the latissimus dorsi muscle flap. There have been no signs of recurrence and is followed in the clinic, as of 4 months after the operation. We think that resection of the abscess, ribs, and, transposition of the muscle flap are useful methods for tuberculous abscess in the chest wall.

A 66-year-old man who underwent an extirpation of thymoma in stage I on September 16 1997 was followed in the outpatient clinic. In October 1998, a chest CT scan revealed a 2.0 x 1.0 cm faint frosted glass like shadow in the right S9. On September 13 1999, the patient was admitted to the hospital for close examination. Two times of transbronchial lung biopsy could not offer any clear diagnosis because the lesion was present so as to encircle the central segment of the B9 gronchus. A segmental resection (S9 + 10) under thoracotomy was performed. Intraoperative frozen section diagnosis was bronchioloalveolar carcinoma (type A according to Noguchi's classification), and a resection of the remnant lower lobe and mediastinal lymph nodes dissection (ND 2 a) were added. With expected increase in frequency of detecting early pulmonary cancer's through CT, clinical cases for which we are obliged to diagnosed the disease by segmental resection may increase, if the lesion develops in the vicinity of the hilum of lung like this case.

We report a successful case of thoracoscopic therapy using a new biological adhesive agent, Gelatin-Resorcinol Formaldehyde glue (GRFG glue) for refractory pulmonary fistula. A 69-year-old male underwent right upper lobectomy for lung aspergilloma. Air leakage began 11 days after lobectomy. Closing alveolar fistula was performed 28 days after first operation. Relapsing air leakage began 2 days after second operation. The insertion of fibrin glue through thoracoscope at two times was not effective for refractory pulmonary fistula. But the insertion of GRFG glue was effective to close the fistula completely.

A 68-year-old male had received a left nephrectomy for renal cell carcinoma of the clear cell type in October, 1987. He had been given Interferon alpha (IFN alpha) for one year since then. He was referred to our hospital for bilateral abnormal shadows on the chest roentgenogram in December, 1997. He underwent a video-assisted thoracoscopic biopsy of bilateral lung in January, 1998, 11 years after his nephrectomy. The resected specimens contained a coin lesions measuring approximately 2 cm in diameter, and the lesions were microscopically diagnosed as a renal cell carcinoma of the clear cell type metastatic to the lung. The patient is doing well with no signs of re-recurrence five months after the resection of the metastatic lesion.

The endogenous flora of the skin and some mucous membranes are well known, however, we were unable to find descriptions about normal esophageal flora in literature. We believe that knowledge about normal esophageal flora is important for therapeutic implications. We compiled data on 30 patients without infection of the oropharynx or esophagus who were admitted for an endoscopy of the upper digestive tract to determine normal esophageal flora. The samples were collected by injecting 10 ml of 0.9% physiological solution into the esophagus and oropharynx and removing it by suction. Esophageal samples from 30 patients and oropharingeal samples from 10 of these patients were collected. We identified mixed flora being Streptococcus viridans the most frequent microorganism found. Where samples from both the esophagus and oropharynx were collected, three occurrences of this same microorganism were found. We concluded that the isolation frequency of germs in the esophagus by the method used was high and the most frequently found germ was S. viridans. There is therefore a possible correlation between the flora from the oropharynx and the esophagus.

We present a case of lipoma arising from the chest wall spreading into the thoracic cavity. Although asymptomatic, a 65-year-old female was pointed out an abnormal shadow on the chest X-ray film taken at the mass survey. The tumor, measuring 3.4 x 3.0 x 2.0 cm in diameter, was surgically removed under thoracoscopic visualization through a small thoracotomy incision of lt. 1st intercostal space, and the diagnosis of lipoma was confirmed postoperatively by histopathologic examination.

A 67-year-old female was admitted to our hospital because of pneumonia-like shadow on chest roentgenogram with persistent cough and sputum of 4 months duration. Diagnosis as lung cancer was delayed more than 4 months. She showed fever and inflammatory reactions. Antibiotics were effective to inflammatory reactions, but not effective to pneumonia-like shadow. Transbronchial lung biopsy was useful for the diagnosis. Right lower lobectomy was performed. In this case, tumor extents were limited within one lobe. Tumor cells did not invade blood and lymphatic vessels, and extrathoracic metastases were not detected. The prognosis of bronchiolo-alveolar cell carcinoma was determined by intra-pulmonary tumor extent. Based on a comparison with the outcome of unresected cases, bronchiolo-alveolar cell carcinoma limited within one lobe should be surgically resected.
