ABSTRACT
IgG4-related disease is a systemic, multifocal, immune-mediated disorder that can affect multiple organs and may present as a tumor, with rare cases described in the maxillofacial region. A female patient, 53 years old, presenting tumor-like mass in the right mandibular region. Magnetic resonance imaging suggested well circumscribed nodular lesion adjacent to the branch / body of the mandible, extending posteriorly to the masseter muscle. During the surgical procedure of excision, a lesion was observed adhering to the right masseter muscle, but it was possible to remove it completely. Histopathological and immunehistochemical analysis suggested diagnosis of IgG4-related disease, furthermore, IgG4 serum count was increased. Actually, the patient continues on periodical followups in our service and by other specialties. Can be concluded that precise diagnosis of this pathology depends on many factors, being challenging and the treatment involves multidisciplinary evaluation due to the possibility of involvement of several other organs.
RESUMEN
La enfermedad relacionada con IgG4 es una condición sistémica, multifocal, mediada por una alteración de la respuesta inmune que puede afectar diferentes órganos o puede presentarse como un tumor, raramente descrito en el área maxilofacial. Se describe el caso de una paciente de sexo femenino de 53 años de edad, presentando una masa tumoral en el ángulo mandibular derecho. La resonancia magnética sugirió un área nodular bien delimitada adyacente al cuerpo mandibular y extendida posteriormente hasta el musculo masetero. Durante la escisión quirúrgica, la lesión se presentaba adherida al musculo de forma lateral siendo posible el retiro total de la lesión. El estudio histopatológico e inmunohistoquimico determinó el diagnóstico de enfermedad relacionada con IgG4 presentando un conteo de igG4 aumentado. Actualmente, la paciente continua con seguimiento por la especialidad. Se puede concluir que el diagnóstico preciso de esta patología depende de algunos factores; el tratamiento debe ser multidsciplinario debido a la inclusión de diferentes órganos en la enfermedad.
