Leiomyoma enucleated from a uterus. External surface on left; cut surface on right. Micrograph of a small, well-circumscribed colonic leiomyoma arising from the muscularis mucosae and showing fascicles of spindle cells with eosinophilic cytoplasm and elongated, cigar-shaped nuclei Immunohistochemistry for β-catenin in uterine leiomyoma, which is negative as there is only staining of cytoplasm ...
Scrotal leiomyoma is considered to be an extremely rare type of genital leiomyoma. Because leiomyomas in the scrotum are usually painless and grow slowly over time, there is a delay in physician referral, with an average of 6–7 years. Physician referral usually occurs when people notice their testicles growing and getting heavier. [11]
Physical examination and ultrasound are sufficient for diagnosing uterine fibroids in the majority of people. When ultrasound findings are inconclusive, magnetic resonance imaging (MRI) may be able to confirm the diagnosis of uterine fibroids in most cases. In addition, MRI can identify benign uterine fibroids with atypical imaging features and ...
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.
No or mild atypia, no tumor cell necrosis ⇒ leiomyoma. If 5 or more mitotic figures are present in 10 high powered fields but the behavior still appears benign, may append “with significant mitotic activity”. Moderate to severe atypia without tumor cell necrosis atypical leiomyoma if < 10 mitotic figures per high power field or
HLRCC is an autosomal dominant condition caused by a mutation in the FH gene, which results in dysfunction of the citric acid cycle, leading to an accumulation of fumarate. [7] [12] The fumarate hydratase gene is located on the long arm of chromosome 1 (1q42.3-43), spans 22 kilobases and has 10 exons; the first exon codes for a signal peptide.
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.
Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
