Abstract:
We present an 18-month-old boy with an exophytic mass in an unusual location, the right anterior-superior gingiva between deciduous teeth 5.3 and 5.4. Histopathologic and immunohistochemical investigations revealed a mesenchymal hamartoma (MH). Collagen fibers were haphazardly distributed in the dermis, admixed with nerve twigs and inflammatory cells. Twelve months of follow-up did not disclose any local relapse or evidence of oncological disease. To the best of our knowledge, this is the first case of gingival MH in an infant.
