case_images: The ultrasound and enhanced CT images are shown in  Figure 1 .
case_images: The typical pathological and immunohistochemistry figures of these four cases. (A) the oxalate crystalline deposits (x100) and (B) the positive AMACR marker (x20) of the tumor in case 1. (C) the positive CD10 marker (x20) of the tumor in case 3. (D) the eosinophilic and prominent nucleoli (x20) of the tumor in case 4.

case_images: The pathological finding that nests of anomalous cells were detected ( Figure 2D ) and expressed immunohistochemistry markers EMA, CAIX, CK8/CK18, FH, SDHB, and PAX-8 suggested that ACD-RCC was considered.

case_images: In 2017, abdominal ultrasound suggested a heterogeneous hypoechoic mass sized 8.8 x 7.2 x 6.7 cm in the left kidney, with a visible border, irregular shape, and a few blood flow signals inside, which was suspected as a tumorigenic lesion ( Figures 3C, D ).
