Introductio: Intravascular papillary endothelial hyperplasia (Masson’s hemangioma) is an unusual, benign,
non-neoplastic, vascular lesion. The lesion is a vascular proliferative reaction following traumatic vascular stasis.

Case Report: In our case a submandibular lesion occurred after insect bite and pathology confirmed it as Masson hemangioma.

Conclusion: Post traumatic red-blue firm lesions should be evaluated pathologically for many differential diagnosis including rare cases such as Masson,s hemangioma.
