Preoperative contrasted CT scans of the patient, showing multiple bilateral kidney tumors, with diameters ranging between 1 and 5 cm. Radiologically, most of the tumors have malignant characteristics due to their hypervascularity and radiopaque enhancement.

On dermatological examination, she had multiple, asymptomatic, white, 1-3 mm sized, dome-shaped, firm papules over the face, neck, scalp, upper trunk, and back, and multiple skin colored, soft, pedunculated papules on the axillae that were clinically consistent with BHDS (Figure 3).
Macroscopic view of one of the tumors removed. The cut section appears light brown and glistering. No necrosis or hemorrhage is noted.
