A 2-year-old male patient came to our service with the complaint of swelling located in the left side of the lower jaw. There was a history of trauma 3 months prior to the lesion formation. The swelling was initially noticed as a small nodule, which increased in size gradually. On palpation, the swelling was well localized, firm, nonmobile, 3 × 3 cm in diameter, nontender, fixed to the underlying bone, and nonadherent to the superficial skin. No submandibular lymphadenopathy was noted. Computed tomography scan of the jaws with a 3-dimensional reconstruction image showed the presence of a soft tissue lesion with bone erosion of the inferior aspect of the left side of the body of the mandible. Histologically, a typical biphasic cellular arrangement was noted. Immunohistochemical markers have been useful for the definitive diagnosis of this uncommon neoplasm. The clinical, radiologic, histologic and immunohistochemical aspects corroborate the diagnosis of infantile myofibroma.
