Introduction: The leiomyoma of the urethra is rare. It a benign mesenchymal tumor that affects smooth muscle urethra. These tumors often occur in women childbearing age middle their appearance about 41 years old. Case report: Here we report case 37 old white woman with progressive dysuria nodule sensation vagina Conclusions: Leiomyoma tumor, common uterus but very rare His diagnosis rarely ment...

Acquiring therapy resistance is one of the major obstacles in the treatment of patients with cancer. The discovery of the cancer stem cell (CSC)-specific drug salinomycin raised hope for improved treatment options by targeting therapy-refractory CSCs and mesenchymal cancer cells. However, the occurrence of an acquired salinomycin resistance in tumor cells remains elusive. To study the formation...

Carcinosarcoma is a rare biphasic neoplasia containing both malignant mesenchymal and epithelial elements. Bladder carcinosarcoma commonly presented as high-grade, advanced stage, and aggressive behavior with a poor prognosis. An 83-year-old male presented with painless gross hematuria to our hospital. Cystoscopy revealed massive nonpapillary bladder tumor on the right wall. The 91 g tumor coul...

: Hydatid cyst is one of the predominantly cystic liver lesions and also a zoonotic disease that highly endemic in Mediterranean region. This condition has extensive differential diagnoses, such as hepatic mesenchymal hamartoma, rare benign tumor, which commonly occurs infants children, extremely adults. Its imaging findings vary from tumor to solid mass occupying or both lobes liver. We report...

Mesenchymal chondrosarcomas are fast-growing tumors that account for 2-10% of primary chondrosarcomas. Cytogenetic information is restricted to 12 cases that did not show a specific aberration pattern. Recently, two fusion genes were described in mesenchymal chondrosarcomas: a recurrent HEY1-NCOA2 found in tumors that had not been cytogenetically characterized and an IRF2BP2-CDX1 found in a tum...

sinonasal teratocarcinosarcoma (sntcs) is a rare tumor characterized by mixture architecture of epithelial and mesenchymal components. sntcs is a highly malignant tumor displaying progressive and aggressive growth with poor prognosis. only about 40% of all patients survive after five years. it seems the combination of surgery and radiotherapy currently is the most effective treatment. in this r...

Tumor cells exhibit two different modes of individual cell movement. Mesenchymal-type movement is characterized by an elongated cellular morphology and requires extracellular proteolysis. In amoeboid movement, cells have a rounded morphology, are less dependent on proteases, and require high Rho-kinase signaling to drive elevated levels of actomyosin contractility. These two modes of cell movem...

Phosphaturic mesenchymal tumors are rare neoplasms predominantly originating in the trunk and extremities. Malignant variants are exceedingly rare, and can present significant diagnostic challenges to the pathologist and otolaryngologist alike. This report describes the first case of malignant phosphaturic mesenchymal tumor involving the larynx, and emphasizes the importance of vigilance in bot...

Background: Aggressive angiomyxoma is a rare mesenchymal tumor with extensive local invasion. It often presents with a lump in the perineal area and pelvic. Since it often does not involve adjacent organs such as the urethra and anus, does not cause obstructive symptoms. Its incidence is 6 times higher in women than men. This tumor grows slowly and has a slight tendency to metastasize. However,...
