Background: Transitional cell carcinoma (TCC) is a rare type of ovarian epithelial cancer. This type of ovarian cancer accounts for only 1% of superficial epithelial carcinomas. Ovarian cancer is a major clinical challenge in obstetrics and gynecology. The reason of this is the lack of specific symptoms for ovarian cancer before the recurrence and progression of the tumor, so many cases are not...
background and aims: p504s (amacr) is a mitochondrial enzyme expressed in renal cell carcinoma. some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. amacr expression increases with higher histological grading in different tumors; however, in rcc it is not obvious. in this study, we tried to investigate if any relat...
pituitary gland metastasis was seen in elderly patients, and the incidence of pituitary metastasis is 1% to 4% of all cancer patients. renal cell carcinoma is a primary malignancy in only 2.6% of pituitary metastases. we reported a 50-year-old man with pituitary metastasis from renal cell carcinoma that had signs of diabetes insipidus. he had multiple lesions in both lungs, and bone scan involv...
Introduction: We report a case of a 64-year old man with a history of colon carcinoma. He underwent fine-needle aspiration by CytoFoam-core and diagnosis of metastatic colon cancer to the thyroid gland. Case presentation: In this case report, a solid thyroid nodule in the right lobe of a 64-year-old male was aspirated. The cytological smears showed a small group of atypical cells with the obvi...
Background: Urothelial carcinoma of the bladder is common cancer. Despite advances in treatments and introduction immune checkpoint inhibitors recent years, metastatic disease carries a poor prognosis
Introduction: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. Case Report: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, ...
Pilomatrix carcinoma is a very rare adenexal tumor which originates in the hair matrix cells and is marked by exophytic growing and common local recurrence, but the metastatic potential is limited. It was first described in 1980 by Lopansri and Mihm, and since then about 90 cases have been reported in the literature. There is no established treatment for the wide local invasion and metastasis o...
Background: Our study aimed to establish a clinically practical and reliable prognostic nomogram based on the important factors predict prognosis of patients with lung metastatic renal cell carcinoma (RCC).
Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer after papillary carcinoma. It usually grows slowly and is clinically indolent; but rarely, its aggressive forms with distant metastases can occur. We report here an uncommon case of bilateral orbital metastasis of FTC. A 70-year-old woman present...
We read with great interest the article by Largillier et al. [1] in which they analyzed prognostic factors in 1038 women with metastatic breast cancer. They did not show the importance of metastasis-free interval as a prognostic factor predicting survival from time of metastatic occurrence in their studies on contrary to other studies stating that early recurrence is an independent predictor of...
