RESUMO
Tuberculous chylothorax is a rare infectious disease that occurs when the thoracic duct is obstructed. Treatment is directed to the tuberculosis infection. A 55-year-old male, driver, born in Trujillo (Peru) is admitted to the emergency department with increasing dyspnea and a 5-day dry cough. The physical examination revealed vocal fremitus, dullness to percussion, and a vesicular murmur that was decreased on the lower 2/3 of the left hemithorax. The X-ray and the thoracic ultrasound revealed significant left pleural effusion. The thoracocentesis drained fluid identified as chylothorax. Subsequently, a thoracic tube was placed, with a decrease in pleural fluid volume and later normalization of the cytochemical changes. Diagnostic video bronchoscopy was performed with a bronchoalveolar aspirate, revealing acid-fast bacilli. The patient received antituberculosis treatment with a favorable outcome. Tuberculous chylothorax is an important cause of chylothorax to be considered in endemic areas of tuberculosis. Proper treatment of the infection leads to resolution of the disease.
El quilotórax tuberculoso es una patología infecciosa infrecuente, que se produce como consecuencia del bloqueo del conducto torácico. Su tratamiento está dirigido a combatir la infección tuberculosa. Se presenta el caso de un varón de 55 años de edad, chofer, natural de Trujillo-Perú, que acudió a emergencia por disnea progresiva y tos seca de cinco días de evolución. El examen físico reveló frémito vocal, matidez y murmullo vesicular disminuido en 2/3 inferiores del hemitórax izquierdo. La radiografía y ecografía torácica evidenciaron derrame pleural significativo, y la toracocentesis reveló quilotórax. Posteriormente, se colocó un tubo de drenaje torácico, con disminución progresiva del volumen del líquido pleural y cambios citoquímicos. Se realizó videobroncoscopía diagnóstica con aspirado broncoalveolar, revelando bacilos ácido-alcohol resistentes. El paciente recibió tratamiento antituberculoso, con evolución favorable. El quilotórax tuberculoso constituye una causa importante de quilotórax a considerar en zonas endémicas de tuberculosis. El tratamiento adecuado de la infección, conlleva a resolución de la enfermedad.

A previously healthy, 52-year-old woman presented with a nine months history of low fever and weight loss (> 30 kg). Physical examination disclosed generalized lymphadenopathy, skin lesions, abdominal distension, mild tachypnea and a left breast mass. Laboratory tests showed anemia; (prerenal) kidney injury, low serum albumin level; and negative serology for HIV and viral hepatitis. Computed tomography (neck/chest/abdomen) showed generalized lymph node enlargement, splenomegaly, pleural effusion and ascites. We performed thoracocentesis and paracentesis, and the findings were consistent with chylothorax and chylous ascites (with no neoplastic cells). Biopsies of the breast mass, skin and lymph nodes were performed and all of them showed large round yeast cells with multiple narrow-based budding daughter cells, characteristic of Paracoccidioides brasiliensis. Consequently, paracoccidioidomycosis was diagnosed, and liposomal amphotericin B was prescribed, as well as a high protein and low fat diet (supplemented with medium chain triglycerides). Even so, her clinical status worsened, requiring renal replacement therapy. She evolved with pneumonia, septic shock and respiratory failure and subsequently died. To our knowledge, this is the first description of a case with chylothorax and breast mass due to paracoccidioidomycosis. Additionally, we discuss: 1- the importance of the inclusion of this mycosis in the differential diagnosis of chylothorax and breast mass (breast cancer), especially in endemic areas; and 2- the possible mechanism involved in the development of chylous effusions.
