Lipomas are benign soft tissue neoplasm. Despite they are the most common tumours of mesenchymal nature in human body, they are unusual in oral and maxillofacial regions The oral cavity occurrence rate ranges from 1% to 4%. The etiology remains unclear and different theories have been proposed to explain the pathogenesis of this tumour. Clinically, lipomas Exhibit painless, well-circumscribed nodular swelling with yellow color or covered by normal mucosa. The case report is about a large and deep-seated lipoma occuring in labiomental region in a 60-year-old-male patient causing esthetic impediment and speech problem. The lesion was removed through intra-oral approach for esthetic reason. No recurrence was reported after 3 months follow-up.
Multifocal epithelial hyperplasia or Heck's disease is uncommon, contagious, asymptomatic, and benign disease affecting the oral mucosa caused by some subtypes of human papilloma virus, especially subtypes 13 or 32. It affects mostly pediatric patients and adolescents in certain geographical regions and ethnic groups. Clinically, the lesion is characterized by the presence of multiple soft papules or nodules in the oral cavity. This paper reports a Tunisian case of 52-year-old man presented with Heck’s disease. The diagnosis is based on both clinical aspect and histopathological features. Clinicians should be familiar with this rare oral disease, which can even affect elderly patients as reported in our case. Treatment is not mandatory and may be indicated when there is esthetic and/or functional impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
