Unique diffused and bilateral minute echogenic lesions, smaller than 2 mm, no acoustic shadow, were scattered within testicular parenchyma. The testicular size of TM had no difference when compared with that of the normal control (P>0.05). Deciduous epithelial cell, glycoprotein, collagen fiber, calcification debris in the seminiferous tubules were found in pathology.Conclusion TM in teenagers was presented with no specific symptoms and signs.
