ABSTRACT
We report a rare case of nonmucinous pulmonary micropapillary adenocarcinoma mimicking pulmonary tuberculosis. A 68-year-old woman was hospitalized with hemoptysis. Her computed tomography revealed cavities and tree-in-bud appearance similar to the extensive form of pulmonary tuberculosis. However, histopathological findings of transbronchial biopsies of all lesions revealed adenocarcinoma and no pulmonary tuberculosis. Tree-in-bud appearance may relate to the floating micropapillary tufts in alveolar spaces. If pulmonary carcinoma is complicated by pulmonary tuberculosis, patients must be isolated and disadvantaged in cancer treatments. Therefore, recognizing this case may be therapeutically useful for respiratory physicians treating both diseases.

We herein report a rare case of fast-growing benign metastasizing leiomyoma. A 52-year-old woman was admitted to our hospital with abnormal chest shadows. Chest computed tomography showed well-circumscribed cystic tumors. Because malignancy could not be completely distinguished in fast-growing tumors, video-assisted thoracic surgery was performed. The pathological findings revealed many cysts and the proliferation of smooth muscle cells. According to the Stanford criteria, the tumor was diagnosed as benign metastasizing leiomyoma. One possible reason for the fast growth of the tumor was enlargement of the cysts. Malignant diseases characterized by cystic tumors are rare but occasionally reported. Therefore, differentiation by a pathological examination is essential.

We herein report the first case of low-dose oxygen therapy for pneumatosis cystoides intestinalis (PCI) using PaO2 as a therapeutic index to prevent acute exacerbation of interstitial pneumonia. An 86-year-old man was admitted to our hospital with abdominal distension. PCI was diagnosed by abdominal computed tomography. Low-dose oxygen therapy was started to avoid acute exacerbation of interstitial pneumonia. The oxygen dose was adjusted so that the PaO2 value was approximately 100 mmHg. After seven days of treatment, the colon gas had disappeared, and no acute exacerbation of interstitial pneumonia was observed. A PaO2 value around 100 mmHg is effective for PCI without inducing acute exacerbation of interstitial pneumonia.

We experienced a case of the successful treatment of intractable pulmonary aspergillosis with inhaled liposomal amphotericin B (L-AMB) and oral voriconazole (VRCZ). A 52-year-old man was admitted to our hospital with a fever. Chest computed tomography (CT) revealed an infiltrative shadow. Two separate sputum cultures detected Aspergillus niger. Although we treated the patient with single and combined antifungal agents, the infiltrative shadow worsened. After obtaining sufficient informed consent from the patient, we switched him to an inhaled L-AMB. The infiltrative shadow subsequently improved. The patient has remained well for one year without exacerbation. We herein report the usefulness of inhaled L-AMB and oral VRCZ.
