A Massive Tuberculosis Abscess at the Erector Spinae Muscles and Subcutaneous Tissues in a Young Man

Tuberculosis (TB) is a chronic granulomatous infection which can present in an atypical form. Isolated muscle involvement is very rare. We report a 25-year-old man who presented with a massive cystic swelling on the right side of his back, extending from the lower thoracic to the gluteal region. He had a history of contact with a friend who was suspected of having TB. Magnetic resonance imaging (MRI) showed that the origin of the cyst was from the erector spinae muscles. The result of a fluid aspirate showed acid fast bacilli. The swelling disappeared after treatment with anti-tuberculous medications. Muscular involvement in TB is very rare. In our patient, the reports of an ultrasound and MRI confirmed isolated muscle and subcutaneous involvement without bony lesions. This case is reported to increase physician awareness regarding soft tissue TB. Although it is rare, similar cases may be seen in the future

Fibromatosis extraabdominal agresiva: descripción de un caso y revisión de la literatura

El tumor desmoide es un raro tumor benigno de partes blandas, con gran capacidad invasiva local y sin potencial metastático. Se han descrito diversas variedades según su localización; siendo la variedad extraabdominal ó fibromatosis extraabdominal agresiva, en la que centramos nuestra revisión, más frecuente en las cinturas escapular y pélvica. Presentamos el caso de un varón de 35 años con un tumor localizado en cadera izquierda, que provocaba una cadera en resorte sintomática. Se valora la bibliografía existente sobre esta patología haciendo hincapié en las características biológicas del tumor, su histología, historia natural y tratamiento.Desmoid tumour is a rare benign neoplasm of soft tissues, with local aggressivity and without metastatic possibility. There are different types depending on its location, the one we are going to review being the extraabdominal one or aggressive extra-abdominal fibromatosis, the one we are going to review, more frequent in scapular and pelvic waists. We report a case of a 35 years old man with a tumour in his left hip, with clinical findings of snapping hip. A review of the existing literature on this pathology is also carried out, with special emphasis on the biological characteristics of the tumour, as well as its histology, natural history and treatment
