Common Signs and Symptoms of Urethral Squamous Cell Carcinoma

Urethral squamous cell carcinoma, a type of cancer that affects the urethra, can exhibit various signs and symptoms. These may include:

• Blood in urine: Hematuria is a common symptom of urethral squamous cell carcinoma, where blood is visible in the urine [1].
• Discharge or bleeding from the urethra: Patients may experience discharge or bleeding from the urethra, which can be accompanied by a foul odor [2].
• Frequent urination or a frequent urge to urinate without producing much urine: This symptom is often referred to as urinary frequency or urgency [3].
• Weak or interrupted urine flow: Some patients may experience a weak or interrupted urine flow, which can be a sign of urethral obstruction [4].

It's essential to note that these symptoms can also be indicative of other conditions, and not all individuals with urethral squamous cell carcinoma will exhibit these signs. A proper diagnosis by a healthcare professional is necessary for accurate identification.

To diagnose urethral squamous cell carcinoma, several tests may be ordered or conducted by a healthcare provider.

Tests that examine the urethra and bladder are used to diagnose urethral cancer: This includes tests such as imaging studies (e.g., MRI or CT scans) and biopsy of the affected area. A tissue biopsy is needed to confirm the diagnosis of urethral cancer, including squamous cell carcinoma [7][10].

Blood and Urine Tests: Blood and urine samples may be taken for testing to help diagnose urethral cancer. These tests can help identify any abnormalities in the blood or urine that may indicate the presence of cancer [8][9].

Imaging Tests: Imaging studies such as MRI (magnetic resonance imaging) or CT (computed tomography) scans may also be used to help diagnose and stage urethral cancer, including squamous cell carcinoma [6][16].

Pelvic examination: A pelvic examination may be performed by a healthcare provider to look for any lumps or abnormalities in the affected area. If this exam suggests urethral cancer, further tests may be ordered, including a urethral biopsy [10].

It's worth noting that squamous cell carcinoma is the most common type of urethral cancer, and it forms in the thin, flat cells in the part of the urethra near the bladder in women, and in the lining of the urethra in men [2][4].

The differential diagnosis for urethral squamous cell carcinoma involves considering several other conditions that can present similarly. Some of the key differential diagnoses include:

• Urothelial carcinoma: This is a type of cancer that affects the lining of the urinary tract, including the bladder and ureters. It can also occur in the urethra, particularly in the distal (lower) part [3].
• Adenocarcinoma: This is a rare type of cancer that originates from glandular tissue in the urethra [3].
• Urethral stricture: A narrowing or blockage of the urethra, which can cause symptoms similar to those of squamous cell carcinoma [5].
• Sexually transmitted infections (STIs): Certain STIs, such as gonorrhea and chlamydia, can cause inflammation and scarring in the urethra, leading to symptoms that may be mistaken for cancer [5].
• Bladder cancer: While more common in the bladder, bladder cancer can also occur in the urethra, particularly in the distal part [7].

It's worth noting that the differential diagnosis for squamous cell carcinoma of the urethra is not exhaustive and other conditions may need to be considered on a case-by-case basis.
