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 ...
Fifty percent of uterine fibroids demonstrate a genetic abnormality. Often a translocation is found on some chromosomes. [7] Fibroids are partly genetic. If a mother had fibroids, risk in the daughter is about three times higher than average. [14] Black women have a 3–9 times increased chance of developing uterine fibroids than white women. [15]
A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell-rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [2] Typically, there are no symptoms unless there is a fracture. [2]
Specific genetic alterations may play a role in the development of uterine leiomyomas. A mutation of a single mesenchymal cell, a stem cell that plays an important role in making and repairing bone, and fat – found in the bone marrow and adipose tissues, with the involvement of progesterone and 17 b-estrodiol – can lead to these fibroids.

The soft fibroma (fibroma molle) or fibroma with a shaft (acrochordon, skin tag, fibroma pendulans) consist of many loosely connected cells and less fibroid tissue. [3] It mostly appears at the neck, armpits or groin. The photo shows a soft fibroma of the eyelid.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging. [1]
BMI vs. Body Fat. We’ll start at the very beginning: Body mass index (BMI) is a measure of someone’s weight compared to their height whereas body fat percentage is a measure of how much body ...
Fibrous dysplasia is a very rare [2] nonhereditary genetic disorder where normal bone and marrow is replaced with fibrous tissue, resulting in formation of bone that is weak and prone to expansion. As a result, most complications result from fracture , deformity, functional impairment, pain, and the impingement of nerves. [ 3 ]
