A cemento-ossifying fibroma (COF) is a noncancerous tumor that develops within the bones of the jaw, most often the mandible (lower jaw), and most often near the molar and premolar teeth. It is made up of fibrous tissue mixed with hard tissue that resembles either bone or cementum (the thin layer of mineralized tissue that …

An odontoma is a noncancerous growth that develops within the bones of the jaw and is made up of the same tissues that form a normal tooth — enamel, dentin, cementum, and sometimes pulp. It is the most common type of odontogenic tumor (a tumor arising from tooth-related tissues), making up roughly one in five …

It belongs to a family of cancers called marginal zone lymphomas, all of which originate from a type of mature B …

Follicular lymphoma with a predominantly diffuse growth pattern is a rare and recently recognized subtype of follicular lymphoma — a group of blood cancers that start in B cells, the white blood cells that help the body fight infection. Unlike the more familiar form of follicular lymphoma, in which the cancer cells grow in round …

Myeloproliferative neoplasms are a group of blood cancers in which the bone marrow — the soft tissue inside bones that makes blood cells — produces too many of one or more types of blood cells. Unlike cancers, where cells multiply rapidly and stop functioning, the cells in myeloproliferative neoplasms usually look and work relatively normally …
