Smooth Muscle Neoplasm Presenting as Intrapericardial Myxoma

Journal of the American Society of Echocardiography, 2006
This report describes the echocardiographic appearance of an intrapericardial mass and pericardial effusion in an otherwise healthy patient. The tumor was a globular mass attached to the left atrium by a stalk, suggestive of a myxoma. The mass was successfully excised and the patient had an uneventful recovery.

S100A6 expression in cutaneous smooth muscle neoplasms

APMIS, 2015
The S100A6 protein is expressed in a variety of tissues and distinct staining patterns in S100A6 immunohistochemistry may be useful in the differential diagnosis of difficult lesions. We evaluated the staining pattern of the S100A6 antibody in 22 cases each of pilar leiomyoma (LM), angioleiomyoma (ALM), and cutaneous leiomyosarcoma (LMS).

Myometrium: Smooth Muscle Neoplasms

1983
These tumours are so ubiquitous and well known that their general features require little comment. Histologically, they consist of fusiform smooth muscle cells with abundant eosinophilic cytoplasm and elongated, blunt-ended or tapering, nuclei which are arranged in bundles and whorls (Figure 18.1), the bundles often intersecting at right angles to each

Smooth Muscle Neoplasms of the Urinary Bladder

The American Journal of Surgical Pathology, 2002
We report the clinicopathologic, immunohistochemical, and DNA ploidy findings of 18 leiomyosarcomas of the urinary bladder. In addition, we compare these malignant smooth muscle tumors with 10 cases of urinary bladder leiomyoma. The 14 male and four female patients with leiomyosarcoma ranged in age from 25 to 88 years (mean 64 years). The tumors ranged

Neoplasms and Mass Lesions Involving Muscle

1996
The ability of MRI to demonstrate soft tissue lesions is unexcelled by other imaging methods as reported by many authors since 1984.1-13 The sensitivity and discriminating ability of MRI for muscle and connective tissue pathology is shown throughout this book.

[Atypical intradermal smooth-muscle neoplasm].

Annales de dermatologie et de venereologie, 2018
We report herein a case of atypical intradermal smooth-muscle neoplasm.A 58-year-old man presented with a painless pinkish-white chest nodule ongoing for two years. Histopathology revealed a proliferation of intradermal smooth-muscle cells. Some atypia and 5 mitoses were seen in the most mitotic fields.

Beyond Smooth Muscle—Other Mesenchymal Neoplasms of the Uterus

Surgical Pathology Clinics, 2019
Mesenchymal tumors of the uterus comprise a heterogeneous group of neoplasms of varied biologic potential. In addition to being host to several anatomically unique entities, the uterus may contain mesenchymal neoplasms typically found elsewhere in the body.

Metastasis of malignant neoplasms to skeletal muscle.

Revista espanola de oncologia, 1986
Malignant neoplasms were found at 194 of 723 autopsies carried out at the Marqués de Valdecilla National Medical Center in the period 1980-1982, and in 50 of these there was secondary involvement of skeletal muscle. In 16 cases (8.2%) the primary tumour and/or its metastases had invaded skeletal muscle, but in 34 (17.5%) true macroscopic or microscopic

AMP-Deaminase from Human Uterine Muscle Neoplasm (Leiomyoma)

1995
Leiomyomas 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
