RESUMO

La linfangiomatosis pulmonar difusa es una enfermedad rara caracterizada por una marcada proliferación y dilatación de los vasos linfáticos en los pulmones, la pleura y el mediastino. Se desconoce la prevalencia, y la etiología no se comprende completamente.Una niña de 22 meses ingresó por poliserositis, con derrame pericárdico y pleural. Requirió pericardiocentesis y avenamiento pleural, y presentó drenaje de quilo (1,5-4 litros/día) sin respuesta al tratamiento médico (ayuno, nutrición parenteral y octreotide). Se realizó biopsia pulmonar. La anatomía patológica mostró hallazgos compatibles con linfangiomatosis difusa pulmonar. Comenzó tratamiento con sirolimus y propanolol, que disminuyeron las pérdidas por el drenaje pleural a la semana. Presentó buena evolución; suspendió aporte de oxígeno y se retiró el drenaje pleural. Se externó al cuarto mes de internación. El diagnóstico temprano de la linfangiomatosis pulmonar difusa es difícil de lograr, pero permite aplicar terapéuticas que evitan la progresión de enfermedad y disminuir la morbimortalida


Diffuse pulmonary lymphangiomatosis is a rare disease characterized by marked proliferation and dilation of lymphatic vessels in the lungs, pleura, and mediastinum. The prevalence is unknown and the etiology is not fully understood.A 22-month-old girl was admitted for polyserositis, with pericardial and pleural effusion. She required pericardiocentesis and pleural drainage, presenting chyle drainage (1.5-4 liters/day) without response to medical treatment (fasting, parenteral nutrition and octreotide). A lung biopsy was performed. The pathological anatomy showed findings compatible with diffuse pulmonary lymphangiomatosis. Treatment with sirolimus and propanolol began, decreasing losses due to pleural drainage one week after treatment. She progressed well, discontinued oxygen supply and pleural drainage was removed, leaving the patient after the fourth month of hospitalization.Early diagnosis of diffuse pulmonary lymphangiomatosis is difficult to achieve, but it allows the application of therapies that prevent disease progression, reducing morbidity and mortality.

RESUMO

A rare benign polypoid tumor of the right palatine tonsil is described in a 23 year old male. It contained dilated lymphatic channels surrounded by fibrous tissue and foci of mature fat. The features of this lesion add support to the hypothesis that benign tumors of tonsil may be hamartomas of tonsil rather than true neoplasms. The differential diagnosis of polypoid lesions of the tonsil is discussed.
