Oncology. 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 ...
Leiomyoma may spontaneously occur in any muscle. Depending on the location of the tumor, identification may not be timely until overall mass becomes undeniably noticeable. The symptoms for a 30-year-old male with a 10 cm leiomyoma included "dead leg" pains. Tumor was intertwined with quadriceps muscles, making identification and excision difficult.
Cutaneous leiomyoma, also known as leiomyoma cutis, [ 1] or cutaneous leiomyomata, [ 2] is a benign skin tumor made of smooth muscle cells. [ 3] There are three different types of cutaneous leiomyomas, genital leiomyomas, angioleiomyomas, and piloleiomyomas. Cutaneous leiomyomas can occur sporadically or as a part of a genetic condition.
Prognosis. Improve after menopause [ 1] Frequency. ~50% of women by age 50 [ 1] Uterine fibroids, also known as uterine leiomyomas or fibroids, are benign smooth muscle tumors of the uterus, part of the female reproductive system. [ 1] Some women with fibroids have no symptoms while others may have painful or heavy periods. [ 1]
H&E stain. Hereditary leiomyomatosis and renal cell carcinoma ( HLRCC) or Reed's syndrome is rare autosomal dominant disorder associated with benign smooth muscle tumors and an increased risk of renal cell carcinoma. It is characterised by multiple cutaneous leiomyomas and, in women, uterine leiomyomas. It predisposes individuals to renal cell ...
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. Pain is a common symptom. They are most commonly seen on the extremities. The cause of angioleiomyoma is unknown.
A leiomyosarcoma, also known as LMS, is a rare malignant (cancerous) smooth muscle tumor. [ 1] The origin of the word is from leio- + myo- + sarcoma which means malignant smooth muscle tumor. 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 ...
1 in 200,000 individuals. Cowden syndrome (also known as Cowden's disease and multiple hamartoma syndrome) is an autosomal dominant inherited condition characterized by benign overgrowths called hamartomas as well as an increased lifetime risk of breast, thyroid, uterine, and other cancers. [1] It is often underdiagnosed due to variability in ...
