Problematic Uterine Smooth Muscle Neoplasms
The American Journal of Surgical Pathology, 1994A recent trend in the classification of uterine smooth muscle neoplasms (USMNs) into clinically benign and clinically malignant groups has been to move from exclusive reliance upon mitotic index (MI) to an approach that incorporates additional histopathologic characteristics.

AMP-Deaminase from Human Uterine Muscle Neoplasm (Leiomyoma)
1995Leiomyomas are common, benign tumors which may occur at any location containing smooth muscle cells (1). Most of these tumors originate in the female genital tracts, and in particular, in the uterus. Leiomyomas are relatively avascular and tightly compacted tumors of smooth muscle cells and fibroblasts. Usually they are surrounded by a pseudocapsule of

The Many Faces of Smooth Muscle Neoplasms in a Gynecological Sampling: An Ultrastructural Study
Ultrastructural Pathology, 1997Smooth muscle neoplasms may have a variety of light microscopic and ultrastructural appearances. On one extreme, a spindle cell mass with a fascicular pattern, located in the myometrium, usually does not need electron microscopy or immunohistochemistry to confirm its smooth muscle nature.

Dantrolene, Pelvic Neoplasm, and Muscle Spasms: Report of a Case
JAMA: The Journal of the American Medical Association, 1977To the Editor.— One of the major (and most difficult) problems faced in the treatment of patients with extensive pelvic tumors is the severe pain from sacral plexus and pelvic peripheral nerve invasion by the tumor. Another much less common but equally difficult problem is the treatment of extremely painful muscle spasms that may occur in the lower ...

Muscle Edema Associated with Musculoskeletal Neoplasms and Radiation Therapy
1996The exceptional tissue contrast provided by magnetic resonance imaging (MRI) permits the observation of physiologic and pathologic changes within skeletal muscle. As described in the previous chapters, even physiologic events such as exercise may alter the signal intensity of muscle on MR images,1 and the effects of minor trauma2 and inflammation3 are ...

Smooth Muscle Neoplasms of the Urinary Bladder: A Clinicopathologic Study of 51 Cases
American Journal of Surgical Pathology, 2010Smooth muscle neoplasms of the urinary bladder are relatively rare. We report the largest series to date examining the clinicopathologic features of leiomyomas and leiomyosarcomas of the bladder. This study sought to clarify several issues relating to smooth muscle neoplasms of the urinary bladder: (1) How to distinguish leiomyomas of the bladder from ...

Incidence of mature adipocytic component within cutaneous smooth muscle neoplasms
Journal of Cutaneous Pathology, 2016Angioleiomyoma is a benign smooth muscle tumor of the subcutis. The presence of mature adipocytes has been described in this tumor under the rubric of ‘angiolipoleiomyoma’ or, erroneously, ‘angiomyolipoma’ (these are not PEComas). Previous studies have found adipocytes in only 2–3% of angioleiomyoma.

Association Between Low Relative Muscle Mass and the Risk of Colorectal Neoplasms
Journal of Clinical Gastroenterology, 2017Goals: We aimed to ascertain whether low relative muscle mass is associated with colorectal neoplasm (CRN) risk. Background: CRN and sarcopenia have common pathophysiological mechanisms such as insulin resistance, chronic inflammation, and physical inactivity.

Progression of Neoplasms Deriving from Muscle Tissues
1989Generally, three types of musculature occur in human histopathology: the smooth musculature, as it appears in the intestinal tract and the uterus; the transverse striated musculature, also known as skeletal musculature, comprising the bulk of the body weight; and finally, the cardiac musculature present in the heart and in the portions of the large ...

Endocrine
Neuroendocrine neoplasms (NEN) are rare tumors arising from neuroendocrine cells most commonly in the gastrointestinal-tract. In recent years, advancements in therapeutics have increased survival rates in patients with NEN leading to a greater clinical burden compared to the general population.The aim of this single-center case-control study was to ...
