Vasitis nodosa

A benign condition of the vas deferens

Vasitis nodosa is a benign condition affecting the vas deferens, the duct that conveys sperm from the epididymis to the ejaculatory duct. It is characterized by the presence of small nodular lesions along the vas deferens, often resulting from previous vasectomy procedures.

Pathophysiology

Vasitis nodosa occurs due to the proliferation of epithelial cells and smooth muscle in the vas deferens. This proliferation is typically a response to trauma or surgical intervention, such as a vasectomy. The nodules are composed of hyperplastic tissue, which can sometimes be mistaken for malignant growths, although vasitis nodosa is entirely benign.

Clinical Presentation

Most individuals with vasitis nodosa are asymptomatic and the condition is often discovered incidentally during histological examination following a vasectomy reversal or other surgical procedures involving the vas deferens. In rare cases, patients may experience discomfort or pain in the scrotal region.

Diagnosis

Diagnosis of vasitis nodosa is primarily made through histological examination. The nodules are identified by their characteristic appearance under a microscope, showing proliferation of epithelial and smooth muscle cells. Imaging studies are not typically used for diagnosis.

Treatment

Vasitis nodosa does not usually require treatment, as it is a benign condition. In cases where it causes discomfort or is mistaken for a malignant condition, surgical intervention may be considered. However, this is rare.

Prognosis

The prognosis for individuals with vasitis nodosa is excellent, as the condition is benign and does not affect fertility or overall health. It is important for healthcare providers to distinguish vasitis nodosa from other potentially serious conditions to avoid unnecessary treatment.
