RESUMO
La aparición de zonas de malignización en regiones con prótesis articulares es un hecho muy infrecuente. Presentamos el caso de una paciente que desarrolló un osteosarcoma condroblástico en el área donde tenía implantada una prótesis total de cadera (AU)
Malignant transformation in the area of joint prostheses is very rare. We present the case of a woman who developed a chondroblastic osteosarcoma in the area where a total hip prosthesis had been implanted (AU)

PURPOSE: To describe the demographics, clinical features, etiology, imaging findings, bacteriologic profile, treatment and outcome in patients presenting splenic abscess in a European tertiary hospital. METHODS: Review of the medical charts of patients in whom splenic abscess was diagnosed at a tertiary hospital in Madrid (Spain) within a nine-year period. RESULTS: Twenty-two cases (13 males, 9 females) were found. Mycobacterium tuberculosis was the most frequent causative microorganism, accounting for 8 cases, and immunosuppression the main predisposing factor (in 63.6% of the patients). Symptoms were quite unspecific, leading to a long, median time until diagnosis (17 days). The overall mortality rate was 18.2% and it was 25% in patients with tuberculosis and 14.28% in patients with other causes of splenic abscesses (p=0.6). CONCLUSIONS: Immunosuppressed states are the predisposing condition for splenic abscess in almost two thirds of the patients. We found a higher percentage of M. tuberculosis than that previously reported in the English literature.
