Histopathological analysis of a transthoracic biopsy revealed adenocarcinoma with an immune profile with positive reaction for: vimentin, AE1, CK7, AMACR, RCCM, PAX2, and PAX8 and negative for: CD117, kidney-specific cadherin, and parvalbumin which is consistent with pRCC (Figure 3).
A CT scan of the abdomen and pelvis obtained 3 years after initiation of treatment. The image shows marked improvement of the lung lesion.
