Diffuse fibrous pseudotumor of the testicular tunics associated with an inflamed hydrocele.
Fibrous pseudotumors of the testicular tunics and paratesticular soft tissue are uncommon lesions. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Although these lesions are clinically worrisome for a malignant neoplasm, they are thought to be reactive in nature, since they are composed of dense fibrous tissue with interspersed bland fibroblasts and myofibroblasts and mixed inflammatory cells. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, bandlike myofibroblastic proliferations that encase the testis and are termed fibromatous periorchitis. Herein, we describe a 57-year-old man with a diffuse fibrous pseudotumor/fibromatous periorchitis that encased the left testis and adnexa and arose in close apposition to an inflamed hydrocele.
