(a) Smear depicting dispersed tumor cells admixed with lymphoplasmacytic infiltrate. (b) CECT depicting heterogeneously enhancing suprapubic and inguinal masses. (c) Gross specimen showing bosselated external surface of the larger mass with attached vas deferens and smooth encapsulated smaller mass. (d) Cut section of masses with more variegated appearance of the larger mass.

Many lymphocytes, plasma cells, and occasional epithelioid cells were present [Figure 1(a)]. The smaller mass, lying close to the larger mass, was extending to the right inguinal region [Figure 1(b)]. The smaller one had smooth external surface with relatively less heterogenous cut surface [Figures 1(c) and 1(d)].
(a) Nests and sheets of tumor cells with a tubule at periphery. H&E, 40x. (b) Tumor cells interspersed with lymphoplasmacytic infiltrate with focal presence of pleomorphic cells. H&E, 100x. (c & d) Areas of hemorrhage, necrosis, and cystic change. (e) Tumor cells positive for CD117 and (f) negative for CD30.

Occasional bimultinucleated tumor cells were also seen [Figures 2(a) and 2(b)]. The areas of hemorrhage, cystic change, and necrosis were also observed, the hemorrhage and cystic change being more pronounced in the larger mass [Figures 2(c) and 2(d)]. It revealed diffuse positivity for CD117 and negativity for CD30 [Figures 2(e) and 2(f)], serum alpha-fetoprotein (AFP), and beta-human chorionic gonadotropin (beta-hCG).
