Bladder cancer is categorized into nonmuscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), distinguished by the presence of detrusor muscle invasion. Urothelial cell carcinoma is the most common subtype of bladder cancer. Transurethral resection of bladder tumor (TURBT) is the standard approach for staging and managing NMIBC, while radical cystectomy remains the cornerstone treatment for MIBC.

Clear cell tumors of parotid gland encompass a wide spectrum of neoplasms, including benign and malignant epithelial neoplasms. Additionally, tumors from adjacent structures such as paraganglioma, and metastatic neoplasms may also show clear cells. Overlapping cytological features may cause difficulty in diagnosis.

Background: Plasmacytoid urothelial carcinoma (PUC) is a rare and aggressive subtype that often presents at advanced stages with poor prognosis. This study investigated tumor invasion to better understand tumor behavior and potentially to improve management strategies by comparing the clinicopathologic characteristics of PUC with positive ureter resection margin (+ URM) with PUC with negative URMs (-URM).
Methods: This retrospective analysis used pathology reports from 2017 to 2023 for cases diagnosed with PUC during radical cystectomy (RC).

Rationale: Angiosarcoma is an aggressive neoplasm derived from endothelial cells that may develop anywhere within the body. Here, we report a case of primary gastric epithelioid angiosarcoma initially misdiagnosed as poorly differentiated adenocarcinoma from the preoperative biopsy.
Patient Concerns: The patient was a 60-year-old male admitted to the hospital due to abdominal discomfort.

Despite the College of American Pathologists' recommendation against diagnosing "fat invasion" in urinary bladder biopsies and transurethral resection of bladder tumor specimens (TURBT), some pathologists still consider this scenario as pathologic stage T3. However, a formal evaluation of fat in biopsies/TURBT has not been performed. Material obtained from TURBT is considered as clinical staging (cT) and that obtained from cystectomy is true pathologic staging (pT).
