Testicular ultrasound revealed a solitary isoechoic, highly vascularized lesion of the upper pole of the right testis measuring 1.8 cm x 0.8 cm x 1 cm distinctly separated from the adjacent healthy parenchyma by a well-defined hypoechoic capsule (Figure 1).
Testicular tumor composed of mature adipose tissue and small vessels: seminiferous tubules with thickened basement membrane and atrophic are also observed (H&E stain x10).

This finding, which is also observed in testicular hemangiomas, perhaps predicts a more aggressive behavior of the tumor with higher possibility of recurrence in cases of partial orchiectomy (Figures 2-5).
Same area under higher magnification (H&E stain x20).

This finding, which is also observed in testicular hemangiomas, perhaps predicts a more aggressive behavior of the tumor with higher possibility of recurrence in cases of partial orchiectomy (Figures 2-5).
Area with numerous adipocytes and small vessels, some of them including erythrocytes in their lumen (H&E stain x20).

(a) Microthrombi in capillaries (blue arrows) (H&E stain x20). (b) Endothelial cells of the vascular capillaries are positive (CD34 immunohistochemistry x10). (c) Adipocytes are positive (S100 Protein Immunohistochemistry x40).
