Fibrous pseudotumour of the paratesticular region is a very rare tumour of the paratesticular region.[1]
General
- May be associated with the epididymis or tunica vaginalis of the testis.[2]
- Uncommonly associated with the epididymis (<10% of tumours[3]).

- Moderate eosinophilic cytoplasm.
- Indistinct cellular borders.
DDx:[2]
- Leiomyoma.
- Fibroma of the tunics.
- Fibromatosis.
- Solitary fibrous tumour.
- Inflammatory pseudotumour.
