RESUMO

Alveolar soft part sarcoma (ASPS) is a rare malignant soft-tissue neoplasm of unknown histogenesis. The two main sites of occurrence are the lower extremities in adults and the head and neck in children. We report the first case of pleural ASPS occurring in a 58-yr-old man who presented with progressive dyspnea. A computed tomographic scan of the thorax revealed a large enhancing pleural mass with pleural effusion in the left hemithorax. Wide excision of the pleural mass was performed. Histologically, the tumor consisted of organoid nests of large polygonal cells, the cytoplasm of which had eosinophilic and D-PAS positive granules. Immunohistochemical staining showed that the tumor cell nuclei were positive for transcription factor 3 (TFE3). The pleural ASPS with multiple bone metastases recurred 1 yr after surgery and the patient died of acute pulmonary embolism 1.5 yr after diagnosis.

RESUMO

BACKGROUND: The aim of this study was to study bacteriology and antibiotic susceptibility in patients with community-acquired perforated appendicitis over a five-year-period. MATERIALS AND METHODS: We conducted a retrospective review of the records of adult patients (age > or =18 years) who were diagnosed as having perforated appendicitis at Ulsan University Hospital between January 2007 and December 2011. Patients who had healthcare-associated or hospital-acquired appendicitis were excluded. Intraoperative specimens submitted to the microbiology laboratory were obtained either by aspiration of pus into a syringe or by use of a swab. Anaerobic bacterial cultures were not performed. RESULTS: Among 216 adult patients with perforated appendicitis, we analyzed 163 culture-positive cases. The overall mortality rate of patients was 0.6% (1/163). Escherichia coli was the most common pathogen (93/163, 57.0%), followed by Streptococcus spp. (45/163, 27.6%), Pseudomonas aeroginosa (13/163, 7.9%), and Enterococcus spp. (17/163, 10.4%). The susceptibility of E. coli to quinolones (ciprofloxacin or levofloxacin) was 74.1%. The susceptibility of E. coli to amoxicillin/clavulanate, cefoxitin, ceftriaxone, piperacillin/tazobactam, and carbapenem reached 75%, 86%, 90%, 98%, and 100%, respectively. Isolated E. coli, including ESBL producing organism and P. aeroginosa, were highly susceptible to piperacillin/tazobactam. Empirical antibiotics used most commonly were a combination of third generation cephalosporin and metronidazole. CONCLUSION: E. coli was the most common pathogen of community-acquired perforated appendicitis, and resistance to quinolone was greater than 25%. We cannot recommend quinolones for use as empirical therapy for treatment of perforated appendicitis.

RESUMO

Cystic lesions or progressive cystic changes in adenocarcinoma of the lung have rarely been reported. We report a case of lung adenocarcinoma that progressed from ground-glass opacities (GGOs) and consolidations or nodules to extensive cystic lesions during 12 months in a young adult patient. A 29-year-old male was initially diagnosed with primary lung adenocarcinoma by transbronchial lung biopsy of the right lower lobe and lung to lung metastasis in both lungs according to imaging findings. The initial chest computed tomography (CT) scans showed multifocal GGOs, consolidations, and nodules in both lungs. Despite treatment with palliative chemotherapy, the patient's follow-up CT scans showed multiple, cystic changes in both lungs and that the lesions had progressed more extensively. He died of hypoxic respiratory failure one year after his diagnosis.
