Abstract

Solitary fibrous tumor of the pleura (SFTP) is an uncommon entity, generally with an indolent behavior. Nevertheless, some malignant forms have been rarely reported. These, often have an aggressive biological behavior with pathological findings of invasiveness. The preoperative diagnosis and evaluation of the grade of malignancy are extremely challenging. Herein we report a case of a 64-year-old man who presented with a left giant intra-thoracic mass imaged with fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG/PET-CT) and sampled via fine-needle aspiration biopsy (FNAB). Imaging and FNAB findings showed suspicion of a benign form of SFTP. Surgical radical resection of the giant mass was performed. The definitive histological diagnosis showed a malignant SFTP. Based on this report, we take the opportunity to briefly discuss the insidious pitfalls concerning the radiological and 18F-FDG/PET-CT features as well as cyto/histological findings in the pre-operative diagnostic work-up examination of this rare entity.

Resumen

El tumor fibroso solitario de la pleura (TFSP) es una entidad poco frecuente, en general con un comportamiento indolente. Sin embargo, algunas formas malignas rara vez han sido publicadas, presentando a menudo un comportamiento biológico agresivo con hallazgos patológicos de invasión. El diagnóstico preoperatorio y la evaluación del grado de malignidad es extremadamente difícil. Presentamos el caso de un paciente de 64 años de edad con una masa intratorácica gigante. Se realizó TC, 18F-FDG/PET-TC y biopsia por aspiración con aguja fina. Los hallazgos de imagen y de la biopsia hacían sospechar de una forma benigna de TFSP. Se realizó la resección quirúrgica radical de la masa gigante. El diagnóstico histológico definitivo mostró el TFSP maligno. Aprovechamos la oportunidad de este caso para revisar los aspectos relativos a los estudios radiológicos, características de la 18F-FDG/PET-TC y los hallazgos cito-histológicos en la evaluación preoperatoria de esta rara entidad.
