We present the case of a 73-year-old man, diagnosed with metastat ic kidney cancer, who had been receiving oral sunit inib monotherapy 375 mg/ d for 4 years, with an acceptable level of disease cont rol. The pat ient was referred to our department for assessment of a painful, asymptomat ic, erythematous-violaceous, moderately indurated, confluent dermatosis that was present bilaterally and was most intense over the metacarpophalangeal j oints and, to a lesser extent , the interphalangeal j oints. This inflammatory process followed a linear dist ribut ion over the extensor tendons of the hands and feet (Figure 1, A and B). St rikingly, the palms of the hands and soles of the feet were completely unaffected.
La condromatosis sinovial es una entidad patológica poco frecuente donde se desarrollan cuerpos de aspectos cartilaginosos a partir de la membrana sinovial de articulaciones, bursas o vainas tendinosas, generando cuerpos libres productores de la sintomatología. Presentamos un caso de 16 años que consulta con dolor de hombro derecho, progresivo sin antecedente de trauma previo, de 3 años de evolución. Se realizan estudios imagenológicos correspondientes llegando a la conclusión diagnostica de condromatosis sinovial de hombro. Se realiza el tratamiento quirúrgico definitivo por artroscopía, logrando remisión de los síntomas y evolución favorable sin recidiva hasta los 5 años de evolucion.
