Abstract
A 7-year-old male patient was referred to a dentistry specialty center because of several papillary lesions of the same color as the surrounding mucosa, which were painless and nonbleeding in the inner cheek and labial mucosa. The diagnosis hypothesis was multifocal epithelial hyperplasia (Heck disease). An incisional biopsy was performed, and the histopathologic findings in stratified squamous epithelium were parakeratosis, acanthosis, and thick epithelial rete ridges, sometimes being club-shaped. The epithelial cells presented nuclei surrounded by clear halos, mitotic figures, and mitosoid cells. The underlying connective tissue presented scarce inflammatory cells. The data confirmed the original clinical hypothesis of multifocal epithelial hyperplasia (Heck disease). No treatment was performed because of the self-limited characteristics of the disease. The patient is now under 6-month follow-up, already showing early signs of lesion remission.
