Rare case of paratesticular solitary fibrous tumour (lipomatous
DOI:
https://doi.org/10.5489/cuaj.424Abstract
A 26-year-old male presented with an asymptomatic 6-cm leftparatesticular mass. Ultrasound and magnetic resonance imaging
confirmed this mass as extratesticular, likely a tumour arising
from the left spermatic cord. The mass demonstrated marked avid
enhancement on post-contrast images, suggestive of a spermatic
cord sarcoma. A left inguinal exploration was performed and gross
examination of the mass revealed a well-circumscribed tumour
with a discrete capsule separating it from the ipsilateral spermatic
cord. The mass was resected without performing an orchiectomy
and histology demonstrated a solitary fibrous tumour (lipomatous
hemangiopericytoma), with minimal proliferative activity and negative
margins. The occurrence of a paratesticular solitary fibrous
tumour is exceedingly rare, with only a handful of case reports.
We review the literature regarding this rare entity and discuss its
diagnosis and management.
