Early Stage Inflammatory Scrotal Pseudotumor

Inflammatory pseudotumors have been described in many organs but they are rare in the testis.' They are ohn classified as fibrous pseudotumors or spindle cell nodules.2 Inflammatory pseudotumors represent a new category of apparently benign postoperative proliferative spindle cell lesions resembling sarcoma. Hydrocele and antecedent scrotal trauma are associated with these asymptomatic nodules in 45% of cases.3 CASE REPORT A 22-year-old man presented 2 months after scrotal trauma with an asymptomatic scrotal nodule. The nodule had a strong elastic consistency and it was separate from the testicle, epididymis, spermatic cord and corpora cavemosa. Scrotal sonography revealed a nonhomogeneous 3 x 4 x 3.7 cm. mass. Cystourethrography confirmed no relationship with the urethra. htal magnetic resonance imaging showed a nonhomogeneous nodule without hemorrhagic areas median to the crura penis that did not infiltrate the scrotal layers or Buck's fascia (fig. 1). The nodule was surgicdy removed and biopsies of adjacent areas were obtained. Histological examination revealed a polymorphous inflammatory infiltrate with neutrophils, plasma cells, lymphocytes and a small number of eosinophils, histiocytes and spindle cells. Foci of hemorrhage and hyalinized collagen were also noted but mitotic figures and atypical cells were absent (fig. 2). After 6 months there was no recurrence. DISCUSSION
