Intratesticular vasculitis simulating a testicular neoplasm

Testicular vasculitis: findings differentiating isolated disease from systemic disease in 72 patients

Testicular vasculitis (TV) may be part of systemic (testicular) vasculitis (STV) or may exist as single-organ/isolated (testicular) vasculitis (ITV). In the current study we sought to identify clinical and histologic features that distinguish STV from ITV. The distinction was deemed important because it is already well established that in other forms of single organ vasculitis, surgical therapy alone may be curative. We identified patients with biopsy-proven TV from pathology databases from our institution and from an English-language PubMed search. Patients were included if data were available to determine TV extent confidently. Data recorded included clinical, laboratory, and histologic features; treatment; and clinical follow-up. The study included 72 patients with TV (mean age, 42 yr; range, 4-78 yr) (7 from our institution). About 74% of patients presented with painful testicular swelling/mass, 10% with a painless testicular swelling/mass, and 4% with epididymal swelling/mass. Eleven percent had no testicular complaints and vasculitis was discovered at autopsy or in other surgical interventions. Vasculitis involved the testicle in 80.3% of cases, the epididymis in 44.6%, and the spermatic cord in 30.6%. Thirty-seven (51%) patients had ITV and 35 (49%) had STV. No differences between ITV and STV patients were found in regards to age, presenting testicular features, duration of testicular symptoms, and time of follow-up. Compared to ITV patients, STV patients presented more often with constitutional/musculoskeletal symptoms (74.3% vs. 8.3%, respectively; p = 0.0001), elevated erythrocyte sedimentation rate (94.7% vs. 16%; p = 0.0001), and anemia (50% vs. 0%; p = 0.0001). Neoplasm was more frequently suspected in ITV than in STV (74.2% vs. 31.6%; p = 0.001), but only occurred in 2 ITV patients. Long-term glucocorticoid therapy was given only to STV patients, and 59.1% of them also received cytotoxic agents. ITV was diagnosed more often by orchiectomy (81.1% vs. 42.9%; p = 0.001) and less frequently by testicular biopsy (2.7% vs. 28.6%; p = 0.003) than STV. Nongranulomatous inflammation affecting medium-sized vessels occurred in most patients with both ITV and STV. Among STV, polyarteritis nodosa was the most frequently diagnosed (63%), followed by Wegener granulomatosis (17%).In summary, TV occurs as ITV in men usually presenting with a testicular mass in the absence of systemic symptoms and normal laboratory results. In most ITV patients, a testicular neoplasm is initially suspected, and TV is an unexpected finding. After surgical removal, ITV does not require systemic therapy. Polyarteritis nodosa is the systemic vasculitis most frequently associated with testicular involvement.

There is a mass in the scrotum-what does it mean?: Evaluation of the scrotal mass

Similar to the experience of finding a lump upon physical examination of the breast, the detection of an intrascrotal mass is often a frightening experience for both the patient and his physician. Ultrasound is a nearly ideal modality for evaluation of the scrotum. This manuscript will review the sonographic assessment of the common pathologic and normal conditions that may present as a mass within the scrotum, including discussion of intratesticular and extratesticular etiologies.

Sonographic appearance of isolated necrotizing vasculitis of the testis

The presentation of necrotizing vasculitis of the testis is variable and may mimic a testicular tumor. Necrotizing vasculitis of the testis is characterized by fibrinoid necrosis of the walls of small and medium-sized testicular arteries. We report a patient with isolated necrotizing vasculitis of the testis who presented with clinical imaging findings suspicious for testicular neoplasm. We describe the clinical course and sonographic characteristics of evolving necrotizing vasculitis of the testis, briefly review the literature, and discuss the implications for the diagnosis and management of this condition.

[Spermatic cord mass as a manifestation of systemic vasculitis: a case report and review of the literature]

We report a case of necrotizing granulomatous vasculitis in the spermatic cord in a 35-year-old man with an antecedent of brain stroke 3 years before. The clinical manifestation was as a painless left scrotal mass. The diagnosis was established by histological examination of the spermatic cord. We discuss the physical findings, radiological features and pathological findings, reviewing the literature for previous similar cases.
