NECROTIZING PNEUMONIA AND BROWN PARAPNEUMONIC EFFUSION MIMICKING LUNG NEOPLASM

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm characterized by expression of both mela-nocytic and smooth muscle markers. Only 10 primary malignant lung PEComas have been reported up to date. We report a 59-year-old male who presented with a lung neoplasm, found during the routine X-ray examination. Preoperative CT-scan revealed the 3,5-cm-sized mass, located at the border of the upper, middle and lower lobes of the right lung. Patient underwent a thoracotomy, resection of the upper, middle and lower lobes of the right lung accompanied with mediastinal lymphadenectomy. After surgery, chylothorax was revealed. Conservative treatment was unsuccessful, so we performed laparoscopic clipping of the thoracic lymph duct. Patient was dismissed from hospital on the 10-th day after the second operation in good condition. In this report, we intend to increase the limited knowledge relating to natural history and optimal treatment of such a rare condition as a primary malignant lung PEComa.

Source Of Infection

We observed a number of cases of sepsis from bacteremia in children from community-associated methicillin-resistant Staphylococcus aureus (MRSA), which led us to study its patterns of infection and outcome. A retrospective review identifying children admitted to our institution with blood culture-proven community-associated MRSA sepsis over a 2-year period was performed. The inclusion criteria were younger than 19 years old, two or more blood cultures for MRSA within 48 hours of admission, evidence of systemic inflammatory response syndrome, and no prior hospital admissions within 6 months. Eight patients were included; seven required mechanical ventilation. Vasopressors were required in seven patients. Four patients required extra-corporeal membrane oxygenation. Four patients had culture-proven septic arthritis or thrombophlebitis and three of these patients developed bilateral necrotizing pneumonia. Bilateral necrotizing pneumonia was identified in the other four patients, but the primary source of infection was never identified. The overall intact neurologic survival was 50 per cent. Children with severe community-associated MRSA sepsis can rapidly progress to cardiorespiratory failure. Mortality appears to be high, and children may benefit from a search of their soft tissues and joints to identify the source of infection to prevent embolic dissemination.

Present Systematic Review

Abstract Purpose The present systematic review aimed to examine the relationship between lung neoplasm and human chorionic gonadotropin (HCG). Especially, women with lung neoplasm mimicking as ectopic pregnancy were explored. Methods A rare case of lung neoplasm with high serum β-HCG, which was initially thought to be ectopic pregnancy, was reported. A literature search was performed of the US National Library of Medicine (MEDLINE), EMBASE, PubMed, and the Cochrane Database of Systematic Reviews using appropriate keywords and subject headings to February 2020. Results Studies assessed lung neoplasm patients with positive HCG were included. Twenty studies, including 24 patients, were included. These cases illustrate the importance of considering the possibility of paraneoplastic secretion of β-HCG in patients who have a positive pregnancy test. This may prevent a delay in the diagnosis and treatment of malignancy in young women. Of the 24 cases, only 7 (29.17%) were managed surgically; others were managed conservatively or with chemotherapy or radiation. Conclusion The present systematic review shows the need to re-awaken awareness and high index of suspicion to lung neoplasm diagnosis in patients with positive pregnancy test.
