Seventy-Year-Old Man With Large Bladder Mass: Diagnostic and Clinical Challenges of an Uncommon NeoplasmMarch 15th 2017
A 70-year-old man presented at our institution for a second opinion regarding diagnosis of a urinary bladder mass. He had a 3-year history of worsening urinary incontinence and urgency, for which he had undergone colonoscopy, as well as testing for prostate issues; all test results were negative.
A Rare Case of Metastatic Renal Epithelioid AngiomyolipomaAugust 15th 2011
The patient is a 43-year-old man who was initially evaluated at an outside institution for unexplained anemia and who was found to have a large right kidney mass. He underwent a radical nephrectomy for a 19-cm large-cell, poorly differentiated neoplasm, consistent with pleomorphic, epithelioid angiomyolipoma (EAML) with extensive necrosis and cytologic atypia.
Rare Bladder Tumors: Caveat EmptorAugust 15th 2010
The authors on “Solitary Extramedullary Plasmacytoma of the Bladder” have provided a quick and accurate diagnosis, work-up, and treatment of this solitary extramedullary plasmacytoma. Solitary extramedullary plamacytomas are rare, and account for only 3% of all plasma cell malignancies. Of the 3% of plasma cell malignancies that are diagnosed, the bladder is one of the least common locations. The rarity of the tumor frequently makes the process of making a correct diagnosis difficult. After making the diagnosis with immunohistochemistry, a bone marrow biopsy must be performed to rule out multiple myeloma. Additionally, a body and skeletal survey must show no evidence of additional disease or lytic lesions in order to confirm localized disease. In this case, these procedures were performed accurately and in a timely fashion.
Recurrent Urothelial Carcinoma With Pulmonary MetastasisDecember 16th 2009
A 56-year-old woman was referred to our institution for a left nephroureterectomy after the diagnoses of a nonfunctioning left kidney and noninvasive papillary urothelial carcinoma of the distal left ureter (Ta grade 1). Following the procedure, surveillance cystoscopy and computed tomography (CT) scan of the abdomen and pelvis demonstrated a large bladder tumor with pan-urothelial extension.
A Man With Changes in the Urinary Bladder: Benign Metaplasia or Adenocarcinoma?February 19th 2009
The patient is a 39-year-old man who presents with pelvic lymphadenopathy. He has a history of ureteral reflux disease, recurrent nephrolithiasis, right nephrectomy, ileal loop diversion of the left ureter, and radical cystectomy for “bladder cancer,” which he underwent 3 years ago. The lymphadenopathy was discovered incidentally during recent imaging.
