Item Airway fibroepithelial polyposis(2017) Labarca, Gonzalo; Caviedes, Iván; Vial, Macarena R; Pires, Yumay; Folch, Erik; Majid, Adnan; Fernández-Bussy, SebastiánFibroepithelial polyps are benign lesions, frequently found in the skin and genitourinary tract. Airway involvement is rare, and few case reports have been published. Our patient was a 79 y.o. male smoker, who was referred to us with a 3-month history of dry cough. At physical examination, the patient looked well, but a chest CT showed a 6-mm polyp lesion in his trachea. A flexible bronchoscopy confirmed this lesion, and forceps biopsies were performed. Argon plasma coagulation was used to completely resect and treat the lesion. Pathological analysis revealed a fibroepithelial polyp (FP). The aim of this manuscript is to report a case of FP with bronchoscopic management and to review the current literature about this condition.Item Dendriform Pulmonary Ossification(American Association of Respiratory Care, 2015) Fernández-Bussy, Sebastián; Labarca, Gonzalo; Pires, Yumay; Díaz, Juan Carlos; Caviedes, IvánDendriform pulmonary ossification is a rare condition often diagnosed by either surgery or postmortem examination. We report a 43-y-old man with a history of nonproductive cough for 1 y. His physical examination was unremarkable. Chest computed tomography showed multiple bilateral micronodules in both lower lobes; however, the patient's pulmonary function was normal. Flexible bronchoscopy with transbronchial biopsies revealed branching ossification. Pulmonary ossification is a chronic process characterized by progressive metaplastic ossification. We reviewed a total of 42 cases of dendriform pulmonary ossification reported in the medical literature: most of these cases were diagnosed by autopsy. Despite its rarity, dendriform pulmonary ossification should be considered in the differential diagnosis of diffuse lung disease. Bronchoscopy with transbronchial biopsies must be considered as a potential diagnostic procedure.Item Endobronchial Involvement in Idiopathic Hypereosinophilic Syndrome(2015) Fernández-Bussy, Sebastián; Antunez, Miguel; Pires, Yumay; Labarca, GonzaloParenchymal lung involvement in eosinophilic syndromes (ES) is frequent; however, it is rarely accompanied by tracheobronchial lesions. The etiologies of ES are infectious [parasites and aspergillus (allergic bronchopulmonary aspergillosis)], rheumatologic disease (antineutrophil cytoplasmic antibody–related vasculitis), drug-associated reaction, acute eosinophilic pneumonia, chronic eosinophilic pneumonia (CEP), and hypereosinophilic syndrome (HES).Item Enfermedad quística adventicial de la arteria poplítea. Presentación imagenológica de una causa rara de claudicación intermitente(2019) Cacho, Javier; Olivares, Juan; Díaz, Jorge; Faure, María; Pires, YumayAdventitial cystic disease of the popliteal artery is a rare condition of uncertain etiology, which presents as intermittent claudication of the lower extremity in middle-age patients. We report a 44-year-old man presenting with intermittent claudication of his left leg. MR angiography showed cystic parietal lesions that caused compression with partial occlusion of the left popliteal artery. Surgical resection of the affected segment was performed, with venous graft interposition. The histopathological analysis of the surgical specimen was consistent with cystic adventitial disease.Item Falla de tratamiento en neumonía adquirida en la comunidad: coccidioidomicosis en un viajero(Sociedad Chilena de Infectología, 2013) Cabello, Hernán; Labarca, Gonzalo; Fernández-Bussy, Sebastián; Cabello, Francisca; Pires, Yumay; Soto, Rodrigo; Thompson, LuisLa neumonía de evolución tórpida son aquellas en que no se logra una respuesta clínica adecuada con el uso de terapia antimicrobiana. Existen múltiples causas a esta falta de respuesta: resistencia antimicrobiana, microorganismos no cubiertos o infecciones por microorganismos atípicos. Coccidioides immitis es un hongo causante de neumonía en el hemisferio norte, especialmente en E.U.A y norte de México. No existen reportes de casos pulmonares importados en Chile. Presentamos el caso de una mujer adulta con una neumonía que no respondió al tratamiento antimicrobiano habitual. Una vez realizado un estudio exhaustivo, se logró establecer mediante el estudio histopatológico la existencia de una coccidiodomicosis como entidad causal, logrando una respuesta clínica y radiológica favorable al tratamiento antifúngico.Item Finger chondroid syringoma as a hypoechoic subcutaneous nodule in ultrasound(Lippincott Williams & Wilkins, 2013) Whittle, Carolina; Mackinnon, John; Cabrera, Roberto; Silva, Claudio; Pires, Yumay; González, RobinsonChondroid syringoma (CS) is an uncommon, benign epithelial skin mixed tumor. It is often located in the head and neck and is unusual in other parts of the body. It may be seen as a skin or soft tissue tumor. We present findings on high-resolution ultrasound and histology in a case of benign CS located on the right index finger. High-resolution ultrasound showed a solid hypoechoic, well-defined subcutaneous mass, adjacent to the tendon. Complete surgical excision was performed, and histopathology demonstrated an apocrine mixed tumor (CS). Although CS histological findings are well described, radiological features have been reported only in few cases and mainly in magnetic resonance. Chondroid syringoma should be suspected by high-resolution ultrasound as a differential diagnosis for a solid slow-growing soft tissue nodule in a finger, especially if the lesion has no contact with the underlying tendon.Item Signo del halo invertido como manifestación inhabitual de neumonía organizada criptogénica. Reporte de un caso(2019) Schiappacasse, Giancarlo; Acevedo, Arturo; Martínez, René; Escobar, Jorge; Hernández, Antonio; Pires, YumayWe report a 64 years old female admitted with fever, cough, dyspnea and lung opacities in the chest X ray. A chest tomography scan (CTS) showed multiple-bilateral ring-shaped opacities and the reversed halo sign (RHS). The patient did not improve with antimicrobial therapy (AT). Infection and rheumatologic causes were excluded, therefore Cryptogenic organizing pneumonia (COP) was suspected with compatible percutaneous biopsy. Systemic steroids were started with a good clinical response. The patient was discharged four weeks after admission in good general conditions and practically no lungs opacities.
