Oral squamous acanthoma. Two additional cases with comments on etiology.
Two new cases of squamous acanthoma are presented, and the their clinical characteristics are compared to the eight cases previously reported. These two additional examples of this lesion are clinically similar to those previously reported. However, one of the two cases exhibits resolution after the removal of sources of trauma, thus lending support to the previously proposed theory of traumatic etiology.
