Nodular and diffuse fibrous proliferation of the penis and tunica vaginalis.
Fibrous benign proliferations of the testis and paratesticular tissues are an uncommon and heterogeneous group of lesions that can mimic true neoplasms. Among them, those considered to be reactive proliferations have been included in the category of fibrous pseudotumors and are often associated with trauma, hydrocele, or infection. We report 2 cases of nodular and diffuse fibrous proliferation. This condition is part of the spectrum of reactive benign fibrous lesions and has previously been described in the testicular tunics and paratesticular region only. One of our 2 cases had the peculiarity of being located in the penile shaft, whereas the other involved the tunica vaginalis. To the best of our knowledge, this is the first report of a diffuse and nodular fibrous tumor involving the penis.
