GOMEZ-OLIVEIRA, Guillermo et al. Low-grade myofibroblastic sarcoma: two rare tumors in two rare locations. Rev Esp Cirug Oral y Maxilofac [online]. 2015, vol.37, n.2, pp.108-112. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2013.04.004.

Low-grade myofibroblastic sarcoma (LGMS) represents an atypical tumor composed of myofibroblasts with a predilection for the head and neck, especially in the tongue and oral cavity, with a high tendency to local recurrences and metastases, even after a long period. LGMS arising in the maxillary sinus and in the neck are extremely uncommon. To the best of our knowledge, only 50 cases of low-grade myofibroblastic sarcoma have been reported. We report two cases of LGMS of the maxillary sinus and neck, discussing clinical, histological, inmunohistochemical and therapeutic features.

Palabras clave : Low grade myofibrosarcoma; Immunohistochemistry; Actin; Recurrences.
