RESUMO
Nontuberculous mycobacterial infection is rarely accompanied by pleural involvement. We report a very rare case of Mycobacterium intracellulare pulmonary disease accompanied with pleural effusion. A 76-year-old man was admitted to our hospital because of dyspnea. A chest radiograph and CT showed bilateral bronchiectasis and bronchopneumonia accompanied with right pleural effusion. The fluid was lymphocyte-dominant exudative effusion, and microbiological examinations of the effusion, including staining and culturing, proved negative. However, one month after admission, subsequent cultures of bronchial washing fluid revealed the presence of M. intracellulare. The patient's effusion was gradually resolved with antibiotic treatment, including clarithromycin.

Squamous cell carcinoma of the duodenum is an extremely rare neoplasm worldwide. A 44-year-old female patient was admitted to our institution for abdominal pain, and she was diagnosed with primary squamous cell carcinoma of the duodenum. The duodenal cancer was inoperable due to vascular invasion and regional lymph node metastasis. The patient was treated with palliative chemotherapy, but her disease progressed, and she was eventually referred to a local hospital for supportive care. The prognosis of squamous cell carcinoma of the duodenum is poor compared with that of usual duodenal adenocarcinoma. We report the details of this case of squamous cell carcinoma of the duodenum along with a review of the literature.

A 46-year-old woman was found to have a huge liver mass that was detected by abdominal ultrasonography. Abdominal CT and MRI showed a 10 cm-sized, encapsulated mass occupying the anterior segment of the right hepatic lobe. Extended right hemihepatectomy was performed and pathological examination revealed fibroblast-like spindle cells within dense deposits of collagen. On immunohistochemical staining, these spindle tumor cells showed an intense CD34 immunoreactivity. The patient is alive without evidence of tumor recurrence 7 months after the resection. Solitary fibrous tumor is a very rare neoplasm found in the liver parenchyma, and it has been reported in less than 30 patients in the English literature. We present here the first such case in Korea.
