relato de caso clínico

Abstract

Introduction: Focal epithelial hyperplasia (FEH) or Heck's disease is characterized as a rare benign lesion of the oral mucosa. It is usually associated with proliferation of the squamous epithelium, mainly attributed to human papillomavirus (HPV) subtypes 13 and 32. Objective: To report the case of a patient with a diagnostic suspicion of HEF, to describe its oral clinical and histopathological manifestations. Methodology: Male, 38 years old, black, attended the University Service with a complaint of burning in the oral mucosa. On clinical examination, she presented multiple papular lesions, firm to palpation, pink in color, with agglomerated or isolated papules, located in the alveolar ridge, inserted gingiva free from the upper and lower arch, jugal and labial mucosa, compatible with lesions caused by HPV. An incisional biopsy of the oral lesions was performed, the histopathological report described the fragment of oral mucosa that was lined with parakeratinized stratified squamous epithelium with prominent acanthosis, focal projections confluent to the connective tissue, confirming the clinical diagnostic suspicion. Conclusion: FEH is a rare, benign mucosal pathology, painless and can resolve spontaneously. Therefore, proper diagnosis through biopsy and histopathological report is necessary.
