Case in brief
An 8-year-old boy presented with a submucosal nodule on the left lateral border of the tongue. A dermoid cyst was initially suspected, but histopathological examination showed thick, interlacing bundles of skeletal striated muscle, establishing the diagnosis of oral rhabdomyomatous hamartoma. The report emphasizes that the lesion’s non-specific clinical presentation makes tissue examination important for diagnosis and management.
What made this case unusual
The lesion was an oral rhabdomyomatous hamartoma in a child, an infrequent site for this congenital lesion, and its presentation mimicked a dermoid cyst.
Diagnostic / clinical pearl
A non-specific oral nodule in a child may not be clinically distinguishable from a dermoid cyst; histopathological examination can establish rhabdomyomatous hamartoma.
Why it matters
Accurate histopathological diagnosis can guide appropriate management and help avoid unnecessary interventions.
