The patient was a 5-year-old boy who was transported to our hospital for a paroxysmal cough, disturbance of consciousness, tonic-clonic convulsions and labored breathing. The patient's respiratory failure persisted after the convulsions remitted, and the presence of an endobronchial foreign body was suspected based on the findings of chest CT performed the following day. A peanut was subsequently removed from the right main bronchus using a bronchoscope with tracheal intubation and bag valve mask ventilation. Immediately after removal, the patient rapidly developed exacerbated hypoxemia, and a reduction in right lung lucency was noted on chest radiography. He was therefore diagnosed with type II postobstructive pulmonary edema, and his condition improved within a short period of time.

Abstract. Palmar fasciitis and polyarthritis (PFPA) is an uncommon disorder clinically characterized by rapidly developing bilateral arthritis of the hands and fasciitis of the palms. This cancer-associated syndrome, primarily linked to ovarian cancer, has also been associated with multiple different malignancies. PFPA symptoms usually precede the detection of ovarian cancer. In all patients from case series and single case reports described, ovarian cancer is already present at an advanced stage. Therefore, the authors aimed to present a case and systematically review available evidence on the association between PFPA and ovarian cancer, as gynecological oncologists. Awareness and recognition of PFPA may allow for earlier diagnosis and treatment of an occult ovarian cancer. The commitment of the attending gynecologists to become familiar with and identify rare diseases may lead to the detection at an early and curative stage and potentially life-saving therapeutic interventions.

The aspiration of foreign bodies may induce various infectious diseases, including actinomycosis, and its association with foreign bodies has been reported. We encountered a patient who developed Actinomyces-induced lung abscess associated with aspiration of cedar leaves. The patient was a 56-year-old Japanese woman who aspirated decorative cedar leaves contained in a lunch box while eating a meal, and coughing and bloody phlegm occurred thereafter. A mass was noted in the right lower lobe of the lung on plain chest computed tomography on the first consultation, and granules of Actinomyces were noted on transbronchial lung biopsy. Long-term antibiotic administration was performed, but no improvement was obtained. Thus, right lower lobectomy was performed. On postoperative pathologic examination, cedar leaves were present in the bronchus, bacterial colonies adhered to these, and there was surrounding inflammatory cell infiltration, mainly involving histiocytes and lymphocytes. This is the first report of Actinomyces associated with aspiration of cedar leaves. When the foreign body cannot be removed, it may be difficult to improve the condition by antibiotic administration alone, and surgery may be necessary.

A 58-year-old man presented with right-sided chest pain. Radiography and computed tomography showed a pleural effusion in the right chest and a mass in the right hilum. Thoracentesis showed a hemothorax. The carbohydrate antigen (CA) 19-9 level in the pleural effusion was very high, requiring differentiation from malignancy. Positron emission tomography showed no significant fluorodeoxy glucose (FDG) accumulation. Magnetic resonance imaging revealed a cystic lesion. The tumor was resected for both a diagnosis and treatment. A pathological examination demonstrated a bronchogenic cyst. An immunohistochemical study suggested that the cyst was the source of the hemothorax and the high CA19-9 level.
