A myoma is a type of tumor that involves muscle cells. [1] There are two main types of myoma: Leiomyomas which occur in smooth muscle. [1] They most commonly occur as uterine fibroids, but may also form in other locations. Rhabdomyomas which occur in striated muscle. [1] [2] [3] They are rare tumors. So-called adult rhabdomyoma has been ...
Uterine fibroids, also known as uterine leiomyomas, fibromyoma or fibroids, are benign smooth muscle tumors of the uterus, part of the female reproductive system. [1] Most people [note 1] with fibroids have no symptoms while others may have painful or heavy periods. [1] If large enough, they may push on the bladder, causing a frequent need to ...
A leiomyoma, also known as a fibroid, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Polycythemia may occur due to increased erythropoietin production as part of a paraneoplastic syndrome.
[1] [5] Most myxomata arise sporadically (90%), and only about 10% are thought to arise due to inheritance. [6] About 10% of myxomata are inherited, as in Carney syndrome. Such tumors are called familial myxomata. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age than other myxomata.
Adenomyoma is a tumor (-oma) including components derived from glands (adeno-) and muscle (-my-). [1] It is a type of complex and mixed tumor, and several variants have been described in the medical literature.
It has an association with tuberous sclerosis. [1] In those with tuberous sclerosis, the tumor may regress and disappear completely, or remain consistent in size. [ 2 ] A common histological feature is the presence of spider cells, which are cardiac myocytes with enlarged glycogen vacuoles separated by eosinophilic strands, resembling the legs ...
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.
The fibroids needed to be removed are typically large in size, or growing at certain locations such as bulging into the endometrial cavity causing significant cavity distortion. Treatment options for uterine fibroids include observation or medical therapy, such a GnRH agonist , hysterectomy , uterine artery embolization , and high-intensity ...
