Hyperplasia of the mucous membrane of the lips, tongue, and less commonly, the buccal mucosa, floor of the mouth, and palate, presenting soft, painless, round to oval sessile papules about 1 to 4 mm in diameter. The condition usually occurs in children and young adults and has familial predilection, lasting for several months, sometimes years, before running its course. A viral etiology is suspected, the isolated organism being usually the human papillomavirus. (Jablonski, Illustrated Dictionary of Dentistry; Belshe, Textbook of Human Virology, 2d ed, p954)
'Mouth diseases' is a broad term referring to various conditions that cause inflammation, infection, or structural changes in any part of the mouth, including the lips, gums, tongue, palate, cheeks, and teeth, which can lead to symptoms such as pain, discomfort, difficulty in chewing or speaking, and altered aesthetics.
Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.
An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.

Oral focal epithelial hyperplasia in a howler monkey (Alouatta fusca). (1/11)

Oral focal epithelial hyperplasia is a rare and seldom reported disease in animals and humans induced by a papillomavirus. The present report is the first description of this disease in a Neotropical primate, a howler monkey (Alouatta fusca). The diagnosis was based on gross and microscopic findings. The generic papillomavirus antigen was identified by immunohistochemistry and was found not to be related to any human papillomavirus DNA tested by in situ hybridization. This virus is probably a specific papillomavirus of the howler monkey (HMPV).  (+info)

Focal epithelial hyperplasia. A rare disease in our area. (2/11)

Focal epithelial hyperplasia is a benign, asymptomatic disease, occurring with very low frequency within our population. It appears as papules, principally on the lower lip, although it can also be found on the retro-commissural mucosa and tongue, and less frequently on the upper lip, gingiva and palate. We present the clinical case of a 9-year-old Saharan girl with lesions that clinically and histologically corresponded to a focal epithelial hyperplasia.  (+info)

Multifocal epithelial hyperplasia. Report of nine cases. (3/11)

Multifocal epithelial hyperplasia (MEH) is also known as focal epithelial hyperplasia, Heck's disease or multifocal papillomavirus-induced epithelial hyperplasia. It is characterised by the presence of multiple lesions in the oral mucosa of children and it has been associated with the presence of the human papillomavirus. The aim of this study was to determine the clinico-pathological features of the cases diagnosed as MEH in the Service of Dermatology of the Hospital Manuel Gea Gonzalez (SDHMGG). The files of the SDHMGG were reviewed and all cases diagnosed as MEH were retrieved. Nine MEH cases were found. Most of the patients were 20 year-old or younger (67%) and females were more commonly affected (78%). All patients presented multiple lesions and always, close relatives with similar lesions were found. Lesions were located most commonly in the buccal mucosa, lower lip and commissures. MEH is a soft tissue intraoral condition that needs treatment solely of the traumatised lesions or those with cosmetic problems. Remaining lesions will disappear with the age of the patients. It is suggested that this entity should be named multifocal epithelial hyperplasia since this name describes better the clinico-pathological and microscopic features of the disease.  (+info)

Extensive focal epithelial hyperplasia: case report. (4/11)

Focal epithelial hyperplasia (FEH) is a rare benign lesion caused by human papillomavirus subtype 13 or 32. The condition occurs in numerous populations and ethnic groups. A higher incidence in close communities and among family members indicates infectious pathogenesis. A 21-year-old woman with FEH is described, in whom the lesions had persisted for 10 years. A literature review is also presented, with emphasis on manifestations in the oral mucosa and histopathological features.  (+info)

Extensive papillomatosis of the palate exhibiting epithelial dysplasia and HPV 16 gene expression in a renal transplant recipient. (5/11)

We report a unique case of extensive papillomatosis of the palate in a renal transplant recipient. The condition resembled inflammatory papillary hyperplasia; it exhibited severe epithelial dysplasia and concurred with generalized gingival hyperplasia. We document and discuss the probable multifactorial etiology of the lesions, including evidence for human papillomavirus (HPV) type 16 expression, as detected by in situ reverse transcription polymerase chain reaction. This report illustrates the need for careful clinical investigation and follow-up of immunosuppressed individuals presenting with apparently benign, common oral lesions.  (+info)

Oral focal epithelial hyperplasia: report of five cases. (6/11)

Focal epithelial hyperplasia or Heck's disease is a rare contagious disease caused by human papillomavirus types 13 or 32, initially described among Native American populations. This condition is characterized by the occurrence of multiple small papules or nodules in oral cavity, especially on labial and buccal mucosa and tongue. This report describes the diagnosis of focal epithelial hyperplasia in five Central Amazonian Indians who sought treatment at the Amazonas State Foundation of Tropical Medicine (FMT-AM), using clinical criteria, polymerase chain reaction (PCR) and DNA sequencing.  (+info)

Focal epithelial hyperplasia, also known as Heck's disease, is a rare, benign oral condition characterized by the proliferation of squamous epithelial cells. It typically presents as multiple, small, white or red, smooth or papillary lesions on the mucous membranes of the mouth, such as the tongue, lips, and buccal mucosa. The lesions are usually painless and asymptomatic, although they may cause some discomfort during speaking, chewing, or swallowing.

The condition is often associated with human papillomavirus (HPV) infection, particularly types 13 and 32. It primarily affects children and young adults, and is more commonly found in Native American populations. The lesions typically regress spontaneously within a few years, although treatment options such as surgical excision or laser ablation may be considered for cosmetic reasons or if the lesions are causing discomfort.

Mouth diseases refer to a variety of conditions that affect the oral cavity, including the lips, gums, teeth, tongue, palate, and lining of the mouth. These diseases can be caused by bacteria, viruses, fungi, or other organisms. They can also result from injuries, chronic illnesses, or genetic factors.

Some common examples of mouth diseases include dental caries (cavities), periodontal disease (gum disease), oral herpes, candidiasis (thrush), lichen planus, and oral cancer. Symptoms may include pain, swelling, redness, bleeding, bad breath, difficulty swallowing or speaking, and changes in the appearance of the mouth or teeth. Treatment depends on the specific diagnosis and may involve medications, dental procedures, or lifestyle changes.

The mouth mucosa refers to the mucous membrane that lines the inside of the mouth, also known as the oral mucosa. It covers the tongue, gums, inner cheeks, palate, and floor of the mouth. This moist tissue is made up of epithelial cells, connective tissue, blood vessels, and nerve endings. Its functions include protecting the underlying tissues from physical trauma, chemical irritation, and microbial infections; aiding in food digestion by producing enzymes; and providing sensory information about taste, temperature, and texture.

Hyperplasia is a medical term that refers to an abnormal increase in the number of cells in an organ or tissue, leading to an enlargement of the affected area. It's a response to various stimuli such as hormones, chronic irritation, or inflammation. Hyperplasia can be physiological, like the growth of breast tissue during pregnancy, or pathological, like in the case of benign or malignant tumors. The process is generally reversible if the stimulus is removed. It's important to note that hyperplasia itself is not cancerous, but some forms of hyperplasia can increase the risk of developing cancer over time.
