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, occur in childhood and often become malignant.
A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
Rare, more common in women. Angioleiomyoma ( vascular leiomyoma , angiomyoma ) of the skin is thought to arise from vascular smooth muscle , and is generally acquired . [ 3 ] Angioleiomyomas appear as small (<2 cm), firm, movable, slow growing subcutaneous nodules .
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.
Fibroids (leiomyoma) — fibroids in the wall of the uterus cause increased menstrual loss if they protrude into the central cavity and thereby increase endometrial surface area. Coagulation defects (rare) — with the shedding of an endometrial lining's blood vessels, normal coagulation process must occur to limit and eventually stop the blood ...
Increased bone resorption leads to hypercalcemia and causes nephrocalcinosis, thereby contributing to kidney failure. Amyloidosis is a distant third in the causation. People with amyloidosis have high levels of amyloid protein that can be excreted through the kidneys and cause damage to the kidneys and other organs. [28] [29]
Louise, a former model and flight dispatcher at London's Gatwick Airport, told BBC that cancer cells had spread around her body, and she would need to remove eight of her organs, including her ...
Embryonal rhabdomyosarcoma (ERMS) is the most common histological variant, comprising about 60–70% of childhood cases. It is most common in children birth to four years old, with a maximum reported incidence of four cases per million children.
