Infantile Myofibroma Eroding into the Frontal Bone : A Case Report and Review of Its Histopathologic Differential Diagnosis

Abstract EN

Infantile myofibroma is a rare and benign tumour of children presenting in the head and neck region.

Rendering a final diagnosis of infantile myofibroma can be challenging in the light of nonspecific clinical, radiological findings and its histopathological similarities with a number of neoplasms especially spindle cell tumours.

In this paper we discuss a case of infantile myofibroma in a 2-month-old infant, enumerating the various differential entities that have to be eliminated in reaching its specific diagnosis and highlighting the importance of immunopositivity to vimentin and smooth muscle actin (SMA) in establishing its myofibroblastic differentiation.
