Fibrous pseudotumor of the epididymis.

Fibrous pseudotumors of the testis: The balance between sparing the testis and preoperative diagnostic difficulty

“…[9] Due to the amount of collagen, calcification or fibroblasts, fibrous pseudotumors can be hyperechoic or hypoechoic on ultrasound without another specific appearance. [10][11][12][13] Slight focal thickening of the tunica albuginea without abnormalities in the testicle may be detected by ultrasound. These lesions can be distinguished from most other testicular lesions according to ultrasound (US) findings, anatomic location, and negative tumor markers, but using these findings, determining the nature of these lesions (benign or malignant) radiologically is difficult.…”

Fibrous pseudotumors of tunica albuginea, tunica vaginalis and epididymis: Report of two cases

“…Fibrous pseudotumors can be hyperechoic or hypoechoic on ultrasound without another specific appearance [11]. Sonographic evaluation generally shows one or more solid masses typically attached to or closely associated with the capsule of the testis.…”

Fibrous Pseudotumor of the Scrotum

“…Since an early reference to a case of a peritesticular fibromatous mass by Sir Astley Cooper in 1830 and a case report by Balloch in 1904, 1,2 various case reports and small series have been published in the urology, pathology, and radiology literature. [2][3][4][5][6] Multiple other names have been applied to this and related entities, including chronic proliferative periorchitis, fibromatous periorchitis, pseudofibromatous periorchitis, reactive periorchitis, an inflammatory pseudotumor, nodular and diffuse fibrous proliferation of the tunica, a benign fibrous paratesticular tumor, granulomatous periorchitis, nonspecific peritesticular fibrosis, a nodular fibropseudotumor, and proliferative funiculitis, [7][8][9][10][11] partly reflecting the variable and overlapping spectrum of pathologic findings and various etiologic theories. Although the terminology, classification, and proposed pathogenesis have been confusing and controversial, these lesions are generally accepted to represent a benign reactive proliferation of inflammatory and fibrous tissue, likely in response to trauma, surgery, infection, or inflammation, as distinct from true benign fibrous neoplasms, which may also rarely occur in the testis and testicular tunics.…”
