Case reportIsolated testicular polyarteritis nodosa mimicking testicular neoplasm—long-term follow-up
Section snippets
Comment
Polyarteritis nodosa is systemic vasculitis characterized by segmental transmural involvement of middle-size arteries resulting in a variety of clinical manifestations in the involved organs. The disease has a male predominance and occurs mainly in the fourth to sixth decades. Involvement of the epididymis is a common finding at autopsy of patients with systemic polyarteritis nodosa, although only the minority of them will have had clinical signs and symptoms.1

Testicular vasculitis: A series of 19 cases
2011, UrologyCitation Excerpt :Isolated organ involvement by PAN is well recognized and sites such as testis, epididymis, appendix, uterus, gallbladder, and breast can be affected.8-11 In cases reported in the literature as isolated testicular PAN, it is interesting to note that although some patients subsequently developed evidence of systemic PAN, others did not show systemic signs and remained asymptomatic after long-term follow-up.1,2,5,6 Therefore, and because PAN is by definition a systemic disease, it is unclear whether similar cases that present locally in the absence of systemic symptoms are best classified as isolated PAN as has mostly been reported in the literature, or as isolated testicular vasculitis with PAN-like features.
Epididimitis: Unusual presentation of periarteritis nodosa
2010, Progres en UrologieIsolated polyarteritis nodosa of the genitourinary tract presenting with severe erectile dysfunction: A case report with long-term follow-up
2009, Journal of Sexual MedicineCitation Excerpt :To our knowledge, the present is also the second report of a presumed isolated genitourinary PAN with no immunosuppressive therapy and long-term follow-up. In the other case with an equal 5-year monitoring [13], PAN affected solely the testis, whereas in the present one kidney and, possibly, penis were involved as well. The management of patients with isolated genitourinary PAN is not standardized.
Acute Painful Scrotum
2008, Ultrasound ClinicsCitation Excerpt :Increased resistive indices may be detected as long as the intratesticular arteries are visible.7 The absence of color flow on Doppler US does not necessarily suggest the diagnosis of ischemia, however, because other conditions such as polyarteritis nodosa can also mimic torsion.23 Earlier, the documentation of testicular or epididymal venous flow by pulsed Doppler was suggested to be indicative mostly of inflammatory diseases or detorsion.24
Isolated polyarteritis nodosa of the male reproductive system associated with a germ cell tumor of the testis: a case report
2007, Cardiovascular PathologyCitation Excerpt :Isolated forms of PAN without evidence of widespread disease are very rare. They have been observed in different organs [1] including the male reproductive system, where they presented mostly as an intrascrotal mass suspicious of neoplasm [3,4], rather than an inflammatory process [2,5]. The clinical course of isolated forms of PAN is usually indolent without need of further treatment after orchiectomy [3,4,6].
