Benign fibrous pseudotumor resulting in orchiectomy despite intraoperative frozen section

Fibrous pseudotumors are rare benign lesions that originate within the paratesticular tissues. Local excision is the preferred method of treatment of these tumors over radical orchiectomy, however a definitive diagnosis must be made beforehand given the similarity of these tumors to malignant entities. We present a case of fibrous pseudotumor of the tunica vaginalis and cauda epididymis. A diagnosis of fibrous pseudotumor could not be established despite the use of intraoperative frozen section, therefore necessitating radical orchiectomy.
