A case of pyogenic granuloma arising in the dorsum of the tongue in an infant with cleft palate

We present a case of pyogenic granuloma arising in the dorsum of the tongue in a 1-month-old boy with cleft palate. Pyogenic granuloma was apparently caused by chronic mechanical irritation to the tongue caused by sucking an artificial nipple.The observation of his tongue movements while nursing were examined with an X-ray TV system to determe how the irritation developed.
