Abstract

Fibrous pseudotumor of the testicular tunics is uncommon lesion. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Two-thirds involve the tunica vaginalis testis, with infrequent involvement of other scrotal structures. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, band-like myofibroblastic proliferations that encase the testis. We report here on a case of fibrous pseudotumor of the tunica vaginalis in 76 year-old patient.

Keywords: Infalmmatory pseudotumor, Tunica vaginalis

Figures and Tables

Fig. 1
Scrotal ultrasonography findings. (A) A slightly hyperechoic lesion that totally replaces the left testis. (B) Doppler ultrasonography shows an increase of vascularity.

Fig. 2
Gross findings. A large nodular paratesticular mass enclosed in tunica albuginea is compressing the atrophied testis (arrow). The mass measures 10×7cm in dimension and it shows whitish homogenous fibrotic cut surface with slightly firm consistency.

Microscopic findings. (A) The mass is composed of dense fibrocollageneous areas. (B) The mass is composed of loose, myxoid areas. A few atypical fibroblasts with enlarged and hyperchromatic nuclei are noted, but without mitosis (H&E stain, ×100).
