MACROSCOPIC DESCRIPTION:
Right orchidectomy specimen, 33g, comprising testis, epididymis and spermatic cord. In the mid pole of the testis, a 12x12x10mm soft to rubbery unencapsulated white nodule is seen. The borders are blurred and merge with adjacent parenchyma in areas. The nodule is confined within the testis, with no extension into the hilum, spermatic cord or through tunica albuginea. The surrounding parenchyma is soft and unremarkable. There is no fluid accumulation in the tunica vaginalis.
The patient went on to have an orchidectomy.
MICROSCOPIC DESCRIPTION:
The sections through the nodule show an unencapsulated, hypocellular area, confined within the testis and comprising predominantly pale eosinophilic stromal material with sparse stellate and spindle cells, small blood vessels and scattered mononuclear embedded within. The stromal material merges into the space between the adjacent seminiferous tubules. No viable tumour seen on H&E sections. In the adjacent testis approximately 50% of tubules are atrophic. A few show luminal calcification. The remainder show active spermatogenesis. There are foci of Leydig cell hyperplasia. Intratubular germ cell neoplasia is not seen. The cut end of the spermatic cord is normal.
In immunostains, there is no staining for AFP, HCG, PLAP or CD30.
FINAL DIAGNOSIS: Scar 12mm in diameter; no viable tumour present.
