    Chronic eosinophilic pneumonia. Report of one case
    (SOC MEDICA SANTIAGO, 2016) Fernandez Bussy, Sebastian; Campos, Felipe; Ogueta, Isabel; Labarca, Gonzalo; Cabello, Hernan
    Chronic eosinophilic pneumonia (CEP) is uncommon and predominantly seen in women. More than 6% of eosinophils in peripheral blood and more than 25% in bronchoalveolar lavage are diagnostic criteria. Secondary causes of hypereosinophilic pneumonia must be ruled out. We report a 72-year-old non-smoker man presenting in the emergency room with a history of cough, fever, and moderate dyspnea. He was not taking any medication. A chest-X ray showed a left lower lobe (LLL) consolidation, and was started on broad-spectrum antibiotics with a presumptive diagnosis of pneumonia. There was no improvement after therapy. A chest CT scan showed increased LLL consolidation and new left upper lobe ground glass opacities as well as a moderate left pleural effusion. Flexible bronchoscopy was performed and bronchoalveolar lavage showed 95% eosinophils, and had negative cultures. No parasites were identified. Transbronchial biopsies demonstrated eosinophil accumulation in alveoli and interstitium and pleural fluid was composed by 85% eosinophils. With the diagnosis of CEP, systemic corticosteroids were used with favorable clinical and radiological response.

    Very High- and High-Frequency Ultrasound Features of Cutaneous Larva Migrans
    (2019) Ogueta, Isabel; Navajas-Galimany, Lucas; Concha-Rogazy, Marcela; Alvarez-Veliz, Sergio; Vera-Kellet, Cristian; Gonzalez-Bombardiere, Sergio; Wortsman, Ximena
    Cutaneous larva migrans is a common infestation among travelers. Although the diagnosis may be suspected clinically, cases can show atypical presentations. We present the ultrasound features of 4 cases at 18 and 70 MHz. Small linear hyperechoic and hyper-refringent subepidermal and intrafollicular structures suggestive of fragments of larvae, hypoechoic dermal and hypodermal tunnels that match with dilatation of lymphatic ducts, and inflammatory dermal and hypodermal ultrasound signs can support the diagnosis. This work suggests that larvae can penetrate the cutaneous basement membrane through the ostia of the hair follicles and potentially disseminate through the dermal and hypodermal lymphatic network.
