The odontogenic myxoma is an uncommon benign odontogenic tumor arising from embryonic connective tissue associated with tooth formation. [1] As a myxoma , this tumor consists mainly of spindle shaped cells and scattered collagen fibers distributed through a loose, mucoid material.
An odontogenic tumor is a neoplasm of the cells or tissues that initiate odontogenic processes. Examples include: Adenomatoid odontogenic tumor; Ameloblastic fibroma; Ameloblastic fibro-odontoma; Ameloblastoma, a type of odontogenic tumor involving ameloblasts; Ameloblastic fibrosarcoma; Calcifying cystic odontogenic tumor; Calcifying ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Ameloblastoma is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. [1] It was recognized in 1827 by Cusack. [2]
The calcifying epithelial odontogenic tumor (CEOT), also known as a Pindborg tumor, is an odontogenic tumor first recognized by the Danish pathologist Jens Jørgen Pindborg in 1955. [1] It was previously described as an adenoid adamantoblastoma , unusual ameloblastoma and a cystic odontoma . [ 1 ]
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma , lymphangioma , ocular surface squamous neoplasia (OSSN), or amelanotic melanoma .
Non-odontogenic cysts form from tissues other than those involved in tooth development, and consequently may contain structures such as epithelium from the nose. As the cyst grows from hydraulic pressure it causes the bone around it to resorb, and may cause movement of teeth or other vital structures such as nerves and blood vessels, or resorb ...
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
