A 10-year-old, clinically healthy, male dromedary camel had
presented a history of progressive unilateral testicular enlargement
over the past 5 years. The animal had mated with 32
females during that period; all had conceived. The sex ratio of
his offspring was one male to 31 females. Ultrasound examination
of the right testicle revealed a diffusely heterogeneous
parenchyma with no identifiable normal testicular tissue. The
enlarged testicle was surgically removed. Macroscopically, the
testicle had a glistening pink surface and contained multiple
soft, bulging nodules. Histopathologically, a well-differentiated,
diffuse seminoma was diagnosed. In conclusion, this
study describes the fertility, sex ratio, clinical findings and
ultrasonographic imaging in a male dromedary camel affected
with unilateral testicular seminoma.
