Extrapulmonary tuberculosis: mimicking metastases in a patient with melanoma in a high TB-burden country; case report.

This is a case report that includes an analysis about extrapulmonary tuberculosis and his singularities, cause can be confused with cancer. Our patient an 83-year-old woman from Pasto-Colombia presents a mimicking metastasis with melanoma. This guides us to understand that extrapulmonary tuberculosis is a rare pathology, but it should be considered as a potential differential diagnosis of any osteolytic lesion.

Biologic osteosynthesis in the treatment of benign and malignant bone tumors.

Background And Objectives: Mechanical augmentation with metal implants in the treatment of bone tumors limits magnetic resonance imaging and computerized tomography scan imaging due to the scattering effect. In addition, modulus of elasticity differences may cause chronic pain. We present a surgical technique in which cortical allografts are used as plates.
