Resumo

Foi detectada uma tumefacção sessil, com 1cm de diâmetro, na mandíbula junto à zona vestibular do dente 46. A doente era uma mulher caucasiana com 35 anos. O crescimento do tumor foi lento durante os últimos três meses. A exerese e o exame histológico revelaram tratar-se de um tumor benigno, não capsulado, bem circunscrito, formado por células esguias alinhadas em bandas paralelas à superfície do tumor, ou ocupando uma área central em que as células eram mais poliédricas ao longo dos espaços vasculares. Este padrão, «zonação» e o facto das células serem imunorreactivas para actina do músculo liso e negativas para desmina permitiu chegar ao diagnóstico de miofibroma solitário. A raridade desta neoplasia torna o caso interessante para publicação.

Abstract

A sessile round swelling, 1cm in diameter, occurred in the right mandibular vestibule close to tooth 46 root of a 35–year old Caucasian female, growing slowly during the last 3 months. Histology of the excised unencapsulated but well circumscribed mass showed a benign neoplasm made up of spindle cells either aligned in bundles parallel to the tumour surface or occupying a central area in which cells were more polyhedric among vascular spaces. This zonation pattern and the fact that cells were immunoreactive to smooth muscle actin and negative to desmin led to the diagnosis of solitary myofibroma. The rarity of this neoplasm made this case worthy of presentation.
