Carcinoma in situ within the bladder trigone with an isolated metastasis to the prostate without involvement of prostatic urethra: a unique case report.

Background: Carcinoma in situ of the bladder is a high-grade cancer that originates in the superficial layer of the bladder. It has the potential to invade nearby organs, and it can spread through blood and lymphatic circulation to distant parts of the body.

Case Presentation: A 58-year-old non-smoker male presented with gross and microscopic hematuria.

A rare case of thyroid-like follicular carcinoma of the kidney in a 75-year-old male: Case report and review of the literature.

Introduction And Significance: The presence of thyroid-like follicular carcinoma in the kidney is very rare, There have been few documented cases of this tumor's formation, and there are no specific signs for this tumor's presence and it is often discovered incidentally by chance, and the diagnosis depends mainly on histological examination and the negative results of thyroid marker tests.

Case Presentation: We describe the case of an adult male who had prostate adenocarcinoma and later suffered from pain in the flank, so radiographic examination showed a mass in the right kidney, which was removed, and the result of histopathologic examination was thyroid-like follicular carcinoma of the kidney.

Clinical Discussion: Although this tumor is rare, we need to keep it in mind as a potential diagnosis for renal lesions in our clinical practice.
