Nodular Prostate: An Overview

A nodule in the prostate refers to a lump or area of hardness under the surface of the prostate gland. In some cases, a prostate stone, which is similar to a kidney stone, can be felt under the surface [1]. These nodules can range from benign conditions, such as prostate enlargement or infections, to more serious concerns like prostate cancer.

Characteristics

A prostate nodule can feel firm and knuckle-like on the prostate gland. Some nodules can be malignant, while others are harmless [11]. The presence of a palpable nodule in the prostate generally mandates referral to a urologist for consideration of a prostate needle biopsy to rule out prostate cancer [5].

Types

Nodular hyperplasia of the prostate is a common disorder in men over 50 in which nodules form from hyperplasia of epithelial and stromal cells. When the nodules become large enough, they can cause problems associated with urination, such as difficulty starting or stopping the flow of urine [3].

Distinguishing Features

True nodules must be distinguished from rectal mucosal lesions and may be due to benign prostatic hypertrophy (BPH), palpable prostatic calculi, or adenocarcinoma of the prostate. With few exceptions, it is mandatory to biopsy all prostatic nodules because the etiology of a nodule cannot otherwise be determined [4].

Diagnosis

Since prostate cancer can be present without symptoms, all men should get regular prostate exams. A careful search must be made for a palpable prostatic "nodule" which is the earliest lesion suggestive of malignancy [9]. A prostate needle biopsy is typically performed to rule out prostate cancer.

Symptoms of Prostate Nodules

Prostate nodules can cause various symptoms, which may vary in severity and frequency. Some common signs and symptoms include:

• Difficulty urinating: This is one of the most common symptoms of prostate nodules, as the enlarged nodule can press against the urethra, making it harder to pass urine.
• Frequent need to urinate: As the prostate gland grows, it can cause an increased frequency of urination, especially at night (nocturia).
• Pain during urination: Pain or discomfort while urinating is another symptom that may occur due to the enlarged nodule pressing against the urethra.
• Blood in urine or semen: In some cases, prostate nodules can cause bleeding in the urine or semen, which can be a sign of cancer.

Other Possible Symptoms

In addition to these common symptoms, other possible signs and symptoms of prostate nodules may include:

• Pain in the genital area, lower abdomen, or lower back
• Pain when urinating
• Hesitancy in urination
• Frequent or urgent urination

Important Note

It's essential to note that not all prostate nodules cause symptoms, and some may be asymptomatic even if they are cancerous. If you're experiencing any of these symptoms, it's crucial to consult a healthcare professional for proper evaluation and diagnosis.

Diagnostic Tests for Nodular Prostate

Nodules on the prostate can be a sign of various conditions, including benign prostatic hyperplasia (BPH) or prostate cancer. To diagnose the cause of a nodule, several tests may be ordered by your doctor.

• Digital Rectal Exam (DRE): A DRE is often the first test used to check for nodules on the prostate. During this exam, a gloved finger is inserted into the rectum to feel the prostate gland and check for any irregularities [13].
• Prostate-Specific Antigen (PSA) Test: If a nodule is detected during a DRE, a PSA test may be ordered to measure the level of PSA in the bloodstream. Elevated levels can indicate prostate cancer or other conditions [12][9].
• Ultrasound and MRI: Additional imaging tests such as ultrasound or MRI may be recommended to get a clearer view of the prostate and confirm the presence of a nodule [13][8].

Other Diagnostic Tests

In some cases, additional tests may be ordered to help diagnose the cause of a nodule. These can include:

• Prostate Biopsy: A biopsy involves removing tissue samples from the prostate gland to examine for cancer cells [7].
• Transrectal Ultrasound with Prostate Biopsy: This test uses ultrasound imaging to guide needles that take tissue samples of the prostate [3].

Treatment Options for Nodular Prostate

Nodular prostatic hyperplasia (BPH) can be treated with various medications, depending on the severity of symptoms and individual patient needs.

The differential diagnosis of nodular prostate refers to the process of ruling out other possible causes of nodules or abnormalities in the prostate gland, aside from cancer.

According to various medical sources [1-3], the differential diagnosis of nodular prostate is broad and includes several conditions such as:

• Benign Prostatic Hyperplasia (BPH): a non-cancerous enlargement of the prostate gland that can cause nodules or lumps in the prostate [4, 12].
• Nonbacterial prostatitis: an inflammation of the prostate gland that can cause nodules or pain in the prostate area [4].
• Tuberculosis of the genitourinary system: a bacterial infection that can affect the prostate gland and cause nodules or other abnormalities [4].

Other conditions that may be considered in the differential diagnosis of nodular prostate include:

• Cystic and solid masses in the prostate: these can be benign or malignant and may mimic the appearance of cancer on imaging studies [5].
• Prostatic stromal tumors: these are rare, non-cancerous tumors that can cause nodules or lumps in the prostate gland [6].

It's worth noting that a digital rectal exam (DRE) is often the first step in diagnosing nodular prostate, followed by further imaging tests such as ultrasound or MRI to get a clearer view of the prostate [13]. A prostate-specific antigen (PSA) test may also be recommended to rule out cancer.

In some cases, a biopsy may be necessary to confirm the diagnosis and rule out cancer. The presence of admixed prostate glands within the spindle cell lesion raises a more specific differential diagnosis, including some patterns of STUMP (Spermatic Cord Tumor with Microscopic Features) [9].

Overall, the differential diagnosis of nodular prostate is complex and requires a thorough evaluation by a healthcare professional to determine the underlying cause.
