Cutaneous Smooth Muscle Tumors in the Dog and Cat

Diagnostic Value of Proliferatin Index Including MIB1 and Argyrophilic Nucleolar Organizer Regions Proteins in Uterine Smooth Muscle Tumors

  Background and Objectives: Uterine smooth muscle tumors are the most common human neoplasm .They are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (STUMP) and differentiation  of these tumors on the basis of H&E staining is impossible . Th...

Smooth Muscle Tumors of the Uterus Pathology

The diagnosis of uterine leiomyosarcoma is usually straightforward since most clinically malignant smooth muscle tumors of the uterus show the microscopic constellation of hypercellularity, severe nuclear atypia, and high mitotic rate generally exceeding 15 mitotic figures per 10 high-power-fields (MF/10 HPF). Frequently, one or more supportive clinicopathologic features such as perior postmeno...

Vascular smooth muscle and the anisotropy of dog carotid artery.

Colorectal mesenchymal tumors - from smooth muscle tumors to stromal tumors.

Colorectal mesenchymal tumors are rare. Therefore, distinguishing between gastrointestinal stromal (GIST) and smooth muscle tumors is important. This study aimed to delineate the immunophenotype and prognostic factors of 75 colorectal mesenchymal tumors. Fifty-three GIST and 22 smooth muscle tumor specimens were included from 1986 to 2007. Forty of 53 GIST were initially diagnosed as smooth mus...

Oropharyngeal Neoplasia in the Dog and Cat

Incidence: Oropharyngeal neoplasia accounts for approximately 6% of canine and 3% of feline cancers. The annual incidence is approximately 20 cases per 100,000 dogs and 11 cases per 100,000 cats. It is more common in the dog than any other species. Older animals (8 – 12 years) are more commonly affected. Oropharyngeal neoplasia has a wide distribution among canine breeds, however, it is commonl...
