Fibrous pseudotumor affecting the tunica vaginalis, epididymis and seminal duct.
OBJECTIVE
To report one case of advanced fibrous pseudotumour.


METHODS
A 34-year-old patient presented with a painless lump on the right side of the scrotum. Examination revealed a hard tissue thickening attached to the tail and body of the right epididymis. The results of the ultrasound study were not clear and multiple differential diagnosis were considered. The lesion was surgically removed by partial right epididymectomy and resection of the affected tunica vaginalis and ductus deferens for anatomopathological study.


RESULTS
The histopathological study revealed an evolved fibrous pseudotumour with bone metaplasia.


CONCLUSIONS
Fibrous pseudotumour is a benign paratesticular lesion that grows slowly and painlessly. It is usually diagnosed by chance or in associated processes such as hydrocele. Differential diagnosis with malignant tumors avoids unnecessary radical treatment.
