Pneumocystis jirovecii Pneumonia in a Patient with Breast Cancer Receiving Neoadjuvant Dose-dense Chemotherapy.

We herein report a 38-year-old woman with breast cancer who developed Pneumocystis jirovecii pneumonia (PCP) during neoadjuvant dose-dense chemotherapy combined with dexamethasone as antiemetic therapy. Chest computed tomography showed bilateral ground-glass opacities and consolidation. The serum β-D-glucan levels were elevated, and P.

Endobronchial Small-cell Lung Cancer with Intraluminal Growth Pattern Showing "Finger-in-glove" Appearance.

Invasion of the endobronchial mucosa by cancer cells is frequently seen in small cell lung cancer (SCLC), but an intraluminal polypoid growth pattern is extremely rare. We herein describe the case of a 69-year-old woman with limited-stage SCLC who had a pedunculated mass in the orifice of the right upper bronchus. Thin-section CT of the lung showed an endobronchial protruding mass accompanied by tubular and branching opacities (the so-called finger-in-glove sign) in the right upper lobe bronchus, which were enhanced by contrast media.

Non-specific interstitial pneumonia associated with clinically amyopathic dermatomyositis showing "crazy paving" appearance on thin-section lung CT.

The "crazy paving" appearance consists of ground-glass opacity superimposed on a network of linear opacities on thin-section computed tomography (CT) images of the lung. This finding has been described in a variety of diseases but is extremely rare in patients with non-specific interstitial pneumonia (NSIP). We describe a 45-year-old woman with biopsy-proven NSIP associated with clinically amyopathic dermatomyositis that showed a "crazy paving" appearance on thin-section CT of the lung.

Clinical characteristics and prognosis of chronic pulmonary aspergillosis.

Background: The details of the clinical characteristics of patients with chronic pulmonary aspergillosis (CPA) have not been fully understood.

Method: One hundred twenty-nine consecutive patients with isolation of Aspergillus species by culture from respiratory specimens who attended our hospital between October 2001 and September 2009 were enrolled. Patients diagnosed with chronic pulmonary aspergillosis (CPA) were retrospectively reviewed for clinical characteristics and prognosis, compared with patients with Aspergillus species colonization.
