Choristomata is an osseous choristoma of the tongue, a very rare condition characterized by a nodule on the dorsum of the tongue containing mature lamellar bone without osteoblastic or osteoclastic activity.[rx] Cartilaginous (chondroid),[rx] and glial choristomas may also very rarely occur on the tongue.[rx]

Pierre Robin syndrome increasingly known as the Robin sequence or Pierre Robin sequence, comprises the triad of micrognathia, glossoptosis, and obstructive apnea. It is a highly heterogeneous condition. Physicians have used varying sets of criteria to make this diagnosis, which has resulted in widespread confusion. Pierre Robin sequence is related to several other craniofacial anomalies

Glossoptosis describes the abnormal formation of the tongue, specifically an upward and posterior positioning toward the throat or pharynx. It can result in an obstructed airway and jeopardize ventilation, along with the ability to properly suck and swallow. The condition, often fully treated in infancy, occurs during craniofacial development and is usually associated with other

Multiple Hamartoma Syndrome/Cowden syndrome or multiple hamartoma syndrome is a genodermatosis originally described in 1963 by Lloyd and Dennis.[rx] It is an uncommon condition that is inherited in an autosomal dominant fashion and is part of a spectrum of other disorders that have mutations in the phosphatase and tensin homolog gene (PTEN).[rx] Cowden syndrome represents the most

Glossoschissis/Cleft tongue syndrome, also called the bifid tongue, has a split running along the length of their tongue. Clefting occurs because the body fails to completely develop in order to join the two sides of the tongue together. Prenatal ultrasounds sometimes detect the presence of the cleft before birth. The cause is usually unknown and

Clefting occurs because the body fails to completely develop in order to join the two sides of the tongue together. Prenatal ultrasounds sometimes detect the presence of the cleft before birth. The cause is usually unknown

Angular cheilitis (AC) is a descriptive diagnosis for an inflammatory skin process of varied etiology occurring at the labial commissure – the angle of the mouth. “Angular,” or commissural, refers to a localized lip inflammation (i.e., “cheilitis,” from the Greek chilos or “lips”) that is distinguishable from the more generalized cheilitides that have different causes. The angles of the mouth

Melanocytes arise from neural crest cells and are frequently found in the skin. However, melanocytes are also found in mucosal membranes. Melanocytes in mucosal membranes are distributed to the oral cavity, nasal cavity, paranasal sinuses, esophagus, larynx, vagina, cervix, rectum, and anus. Melanoma results from a malignant change of melanocytes. Melanoma in the head and neck account
