ABSTRACT
La displasia fibrosa (DF) es una enfermedad fibroósea benigna que consiste en el reemplazamiento de hueso normal con excesiva proliferación de tejido conectivo fibroso con estructuras óseas afuncionales. La forma de DF craneofacial es poco frecuente y no está bien definida. La afectación más frecuente en el área craneofacial se da en el cuerpo de la mandíbula y zona posterior del maxilar. Los autores describen el manejo completo y la rehabilitación funcional de un caso de displasia fibrosa de mandíbula avanzado y revisan las opciones terapéuticas de esta condición (AU)
Fibrous dysplasia (FD) is a benign fibro-osseous disease where normal bone is replaced by an excessive proliferation of fibrous connective tissue with irregular trabecular bone. Craniofacial involvement is uncommon and is not well defined. The most commonly involved bones in the craniofacial area are the mandible body and the posterior maxilla. The authors describe the complete management and functional rehabilitation of a case of advanced fibrous dysplasia of the mandible, and provide an updated review of the therapeutic options for this condition (AU)

Las anomalías vasculares incluyen dos entidades bien diferenciadas aunque frecuentemente confundidas en la literatura científica: los hemangiomas y las malformaciones vasculares. La localización primaria intraósea cigomática es muy infrecuente. Además, la mayoría de los casos publicados han sido categorizados de «hemangioma» de forma poco rigurosa. Los autores describen un caso de malformación venosa intraósea cigomática y discuten las características clínicas, histológicas e inmunohistoquímicas distintivas de las anomalías vasculares que conducen a un adecuado diagnóstico y un tratamiento eficaz (AU)
Vascular anomalies include two well-differentiated conditions that are nevertheless often confused in the scientific literature: haemangiomas and vascular malformations. Primary intraosseous involvement of the zygoma is particularly rare. Moreover, most reported cases of zygomatic involvement have been categorised as haemangioma without appropriate diagnostic criteria. The authors describe a case of intraosseous venous malformation of the zygoma and discuss the specific clinical, histological and immunohistochemical criteria of vascular anomalies that lead to a correct diagnosis and subsequent effective treatment (AU)

PURPOSE: To report an exceptional case of bilateral synovial chondromatosis (SC) of the temporomandibular joint (TMJ) and discuss diagnostic approaches, treatment options and follow-up data. PATIENTS AND METHODS: A 38-year-old woman presented with left preauricular swelling. Initial imaging studies revealed TMJ effusion only. Six years later, synovial calcifications were detected in the left TMJ; the right TMJ space was widened and presented incipient calcium deposits. Open arthrotomy of the left TMJ was performed, with removal of multiple cartilaginous loose bodies and complete synovectomy. Periodic controls proved the asynchronic development of intra-articular bodies in the right TMJ. RESULTS: SC is a metaplastic arthropathy that is uncommon in the TMJ. Bilaterality is exceptional. Diagnosis is often delayed due to the non-specific symptoms, progressive developmental stages and clinicians' lack of awareness of the condition. Magnetic resonance imaging (MRI) is particularly helpful in defining disease extension, excluding a possible tumour and detecting internal derangement. Definitive diagnosis requires arthroscopic or open examination and histopathological analysis. Recurrences are infrequent after arthrotomy, removal of loose bodies and complete synovectomy. CONCLUSION: SC is an uncommon condition in the TMJ. Bilateral involvement is extremely rare. MRI is effective for diagnosis and postoperative follow-up. Complete synovectomy usually yields an excellent prognosis.
