[Diagnostic considerations apropos of a case of keratoacanthoma in a child]

A seven year old child presented with a keratoacanthoma, sometimes defined as a primary idiopathic pseudoepitheliomatous hyperplasia, on the mandibular alveolar process. The lesion showed typical proliferation of a tumoral nature, clinical manifestations and microscopic findings being those of a spindle cell carcinoma and easily mistaken for the latter. The solitary oral form of the tumor is a rare benign affection that does not recur after extirpation. A literature review identified only four similar cases.
