Summary
Malignant priapism, a rare condition, occurred due to penile metastasis from transitional cell carcinoma. This indicates advanced bladder cancer and a poor prognosis for patients.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Transitional cell carcinoma is a common malignancy of the urinary tract.
- Priapism is a prolonged erection not associated with sexual stimulation, often painful.
- Malignant priapism is a rare complication of advanced cancers.
Observation:
- A patient with advanced bladder cancer (pT4G3) presented with priapism.
- The priapism was characterized by painful penile erection.
- A biopsy of the corpora cavernosa was performed.
Findings:
- Pathologic diagnosis confirmed penile metastasis of transitional cell carcinoma.
- The priapism was directly caused by the spread of cancer to the penis.
- This represents a rare presentation of metastatic bladder cancer.
Implications:
- Priapism secondary to penile metastasis signifies advanced disease.
- The condition is associated with a poor prognosis.
- Highlights the importance of considering metastatic disease in patients with priapism and a history of cancer.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
