OBJECTIVETo investigate the clinicopathological characteristics of anthracosilicosis complicated with lung cancer.

METHODSTissue specimens from 16 autopsy cases of 0(+) anthracosilicosis complicated with lung cancer were retrospectively studied by hematoxylin-eosin, histochemical, and immunohistochemical staining.

RESULTSAll of 16 patients were male. The patient's age ranged from 46 to 57 years (average: 52.8 years). The dust-exposure time were over 25 years. The pneumoconiosis and dust fibrosis of different degrees in the lung were found. The positive detected rate of coal silicotic nodules was 93.75% (15/16). Among 16 cases of lung cancer, there were 5 cases of squamous cell carcinoma, and 5 cases of small cell undifferentiated carcinoma, 3 cases of bronchioloalveolar carcinoma, 2 cases of adenocarcinoma and 1 case of adenosquamous carcinoma. The typical pathological changes of anthracosilicosis complicated with lung cancer were: the cancer tissue was located at the side of coal dust fibrous focus and fibrosis lesion, or mixte with silicotic lesion. CK, EMA and CEA were positively expressed in most of the tumor cells, while vimentin was positive in the fibrocyte of dust fibrosis.

CONCLUSIONSThe occurrence of some lung cancer may be related with fibrosis. The dust-exposed workers can suffer from lung cancer which is histologically identical to the general lung tumor. PCNA and Ki67 may be a prognostic index for anthracosilicosis with lung cancer, while vimentin may be a marker for the examination of dust fibrosis in anthracosilicosis.

Pulmonary lymphangioleiomyomatosis has been observed almost exclusively in women, usually in their reproductive years. Exacerbations with pregnancy and after hormonal manipulation have been documented, and it has been suggested that its pathogenesis is due to the influence of hormonal(estrogenic) stimulus. The clinical, roentgenographic, and histopathologic features of this case of pulmonary lymphangioleiomyomatosis in a 22-year-old male are all characteristic of those described in prior reports, except for the patient's sex. With the following case of pulmonary lymphangioleiomyomatosis in a male, we suggest the possibility of the existence of an additional pathogenetic mechanism.

INTRODUCTIONPathological pulmonary hernia is a rare clinical entity which can be caused by malignancies.

CLINICAL PICTUREA 72-year-old female presented with a painful bulge in the left 4th intercostal space. Chest radiography and computed tomography demonstrated a left pulmonary hernia, pleural effusion and destruction of ribs.

TREATMENTThe hernia sac was excised and a part of the chest wall was resected with reconstruction of residual defect.

OUTCOMEThe patient died 2 years after the treatment.

CONCLUSIONSA multidisciplinary approach involving various medical specialists may offer patients with pathological pulmonary hernia remarkable palliation and better quality of life.

Spontaneous pneumothorax is a rare manifestation of metastatic lung cancers and described in advanced diseases or during cytotoxic chemotherapy which is manifested by sudden onset of dyspnea. The cause or mechanism of spontaneous pneumothorax has been unknown, as well as the association with site of metastases or type of cancers or side effect of chemotherapeutic drugs has been reported rarely. A 68-yr-old man underwent excision of angiosarcoma of the scalp. Chest radiography did not show any evidence of possible metastatic lung lesion at that time. Therefore, systemic doxorubicin and dacarbazine were given. After nineteen days of chemotherapy, he developed a bilateral spontaneous pneumothorax and palpable cervical lymph nodes. Both parietal and visceral pleura were intact and showed no evidence of metastatic and pathologic lesions on thoracoscopic evaluation. The patient managed with bilateral tube thoracostomy and both lungs were expanded. Lymph nodes became unpalpable during three cycles of the paclitaxel and doxorubicin, however, bilateral lung metastases were developed and progressed despite chemotherapy. The patient died due to respiratory failure after five months. This report underlines that spontaneous pneumothorax can occur as the first manifestation of metastatic angiosarcoma even if imaging studies do not show of a metastatic lesion.

Inflammatory myofibroblastic tumors (IMTs) are benign neoplasms that can occur at different anatomic sites with nonspecific clinical symptoms. A 48-yr-old woman presented with a 2-month history of a relapsed oral ulcer, progressive dyspnea, and a thoracic pain induced by breathing. A tumorous mass was noticed in the right costodiaphragmatic recess on chest computed tomography and magnetic resonance imaging, and the patient underwent a right costotransversectomy with excision of the tumor, which originated from the 12th intercostal nerve. Histology and immunohistochemistry showed that the tumor was an IMT of the intercostal nerve. The patient's postoperative course was not favorable; dyspnea persisted after surgery, and a progressive pulmonary compromise developed. The cause of the respiratory failure was found to be bronchiolitis obliterans, which in this case proved to be a fatal complication of paraneoplastic pemphigus associated with an IMT. This case of IMT of the spinal nerve in the paravertebral region is unique in terms of its location and presentation in combination with paraneoplastic pemphigus, which is rare. A brief review of the heterogeneous theories concerning the pathogenesis, clinicopathological features, and differential diagnosis of this disease entity is presented.

Pancreatic metastases are found in up to 40% of patients with small cell lung cancer, but metastasis-induced acute pancreatitis is rare. Treatment of metastasis-induced acute pancreatitis is initially supportive, but failure of conservative management are common. There are few reports on aggressive treatment with chemotherapy which lead to rapid clinical improvement and prolongation of survival in patients with metastasis-induced acute pancreatitis. We experienced a case of metastasis-induced acute pancreatitis in a patient with small cell lung cancer. Despite conservative treatment with dietary restriction and intravenous fluid supply, serum amylase levels increased persistently with severe abdominal pain. After chemotherapy with irinotecan and carboplatin, abdominal pain and serum amylase levels resolved dramatically.
