Squamous cell carcinoma metastasis to the kidney

Case contributed by Dr Chris O'Donnell

Presentation

Left loin pain. Previous surgically resected lung SCC.

Patient Data

Age: 60 years
Gender: Female

Typical hypoechoic mass with peripheral blood flow ? atypical cyst or unusual solid lesion.

Duplex ultrasound shows peripheral vascularity

CT could not be performed as patient has had anaphylactic reaction to iodinated radiographic contrast. 

Typical peripherally enhancing solid mass as seen in renal cell carcinoma

Nuclear medicine

PET scan performed some 12 months previously

Hot spot at right hilum at the site of primary malignancy on PET/CT. Left kidney is normal.

CT guided biopsy. Histology demonstrated metastatic squamous cell carcinoma.

Case Discussion

Mass lesion in left kidney looks like a renal cell carcinoma but the PET scan was normal some 12 months previously so it has grown very quickly thus biopsy was performed and showed a metastatic lesion from lung.
