background: mullerian adenosarcoma, a rare tumor, is composed of mixed mesenchymal and epithelial elements. the epithelial component is typically benign and admixed with malignant sarcomatous stroma. this tumor can be distinguished in approximately 8% of all uterus sarcomas and commonly originates in the endometrium as a growing polypoid mass in the uterine cavity. all age groups are affected b...

primary oral melanoma is a rare neoplasm of melanocytic origin, accounting for 0.5% of all oral malignancies. the “chameleonic” presentation of a mainly asymptomatic condition, rarity of this lesion, poor prognosis, and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider. here is a case report presenting a malignant mel...

Introduction Sarcomatoid carcinoma (SC) is a rare subtype of malignant neoplasm with poor prognosis that involves both carcinomatous and sarcomatous components. Although it may develop in various organs, SC the large intestine has rarely been reported. It not for patients to have distant metastasis, reflecting its highly aggressive oncologic features, but cases brain metastasis on initial visit...

Epithelial Protein Lost In Neoplasm (EPLIN), also known as LIMA1 (LIM Domain And Actin Binding 1), was first discovered a protein differentially expressed in normal and cancerous cell lines. It is now to be key the progression metastasis of certain solid tumours. Despite slow pace understanding biological role cells body systems, well its clinical implications early years since discovery, recen...

Introduction: Solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. Occurrence in the parotid gland is exceedingly rare.   Case Report: A 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from Stensen's duct, is described. A pre-operative CT sc...

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

UNLABELLED Spinal cord tumors are a rare neoplasm of the central nervous system (CNS). The occurrence of metastases is related to poor prognosis. The authors analyzed one series of metastasis cases and their associated mortality. METHODS Clinical characteristics were studied in six patients with intramedullary tumors with metastases in a series of 71 surgical cases. RESULTS Five patients ha...

Malignant mesothelioma predominantly arises from the serosal surfaces of the pleural or peritoneal cavity. There is currently no effective standard treatment for mesothelioma and the prognosis for patients is poor; the majority of patients with malignant mesothelioma succumb between 12 and 17 months following diagnosis. The association of all forms of malignant mesothelioma with asbestos exposu...

Development of distant metastases from renal cell carcinoma (RCC) is a frequent occurrence and, in nearly 95% of the cases, secondary lesions present within 5 years following nephrectomy. We performed a left pneumonectomy for a peri-hilar lung mass in an 81-year-old man with history of kidney cancer, resected 37 years earlier. Histopathological examination revealed a solitary lung metastasis fr...

INTRODUCTION Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare. CASE REPORT The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman. In 2010, she underwent total thyroidectomy and right-sided modified radical neck diss...
