%X A 55-year-old man with a history of basaloid squamous cell carcinoma of the oropharynx with laterocervical lymph node metastases 6 years before (and treated with chemoradiation) presented with flank pain and hematuria. Computed tomography scan found a renal lesion, with radiological features more suspicious for primitive renal neoplasia. Histopathological and immunohistochemical examination after surgical excision revealed a basaloid squamous cell carcinoma involving renal parenchyma. Basaloid squamous cell carcinoma is a rare tumor but with a high percentage of distant metastasis, and it is mandatory, also for a general pathologist, to know this disease. Moreover, in a patient with renal metastases, any type of cancer should be taken into account, and this case is emblematic of why the previous medical history is crucial for differential diagnosis
