RESUMO
La afectación de la ATM por una condromatosis sinovial es un hecho muy poco frecuente. Trastorno metaplásico del tejido sinovial, suele producir cuerpos libres, condromas, intraarticulares. Tiene una clínica variabley muy inespecífica. Las pruebas diagnósticas de elección son la RM y la artroscopia. La retirada de cuerpos libres y sinovectomía parcial suele ser terapéutica. Ocasionalmente puede destruir la base del cráneo y extenderse intracranealmente. Se han descrito casos de malignización secundaria. Es necesario el seguimiento a largo plazo del paciente. Presentamos un caso con osteolisis incipiente de la fosa cerebral media
Synovial chondromatosis very rarely affects the TMJ. It is a metaplastic disorder of the synovial tissue that usually produces intra-articular loose bodies, or chondromas. It has variable clinical features and the symptoms are unspecific. Examination by meansof magnetic resonance imaging and arthroscopic observation are the diagnostic techniques of choice. Treatment consists in the removal the loose bodies and partial synovectomy. Occasionally the skull has been destroyed and the middle cranial fossa invaded. There arecases of malignant transformation to chondrosarcoma. A long-term follow up is necessary. We describe a case with incipient intracranial extension

Anomalies of the first branchial cleft are occasional problems putting up diagnostic and therapeutic difficulties, because the imperfect settlement of reminders of this cleft, which can appear as cysts or branchial fistula, among patients of any age. Though there are several recommended classifications in order to achieve a precious diagnosis and a total surgical removal, sometimes is laborious to correlate the clinical and the histological findings. We report a sequence of congenital periauricular anomalies operated in our Department during a ten-years-term and compare our findings of those quoted after the literature series.
