Local recurrence of sinonasal renal cell-like adenocarcinoma: A CARE compliant case report

Rationale: Sinonasal renal cell-like adenocarcinoma (SNRCLA) is a very rare sino-nasal carcinoma. Because SNRCLA has the same morphological features as other clear cell carcinomas, and some of them also occurred in sinonasal part, it is necessary to differentiate SNRCLA from these tumors. Patient concerns: A 42-year-old man presented with complaints of epistaxis for 1 day. The patient had undergone endoscopic resection of a neoplasm in the right nasal passage at another hospital 35 months before and was diagnosed with SNRCLA at that time, and did not receive any other adjuvant therapy. Diagnoses: The postoperative histopathological examination revealed a diagnosis of recurrent SNRCLA. Interventions: The tumor was removed under nasal endoscopy. Outcomes: The patient was followed up for 2 months and recovered well without any complications. Lessons: NSRCLA is a very rare tumor, and should be differentiated from other clear cell tumors including some salivary tumors and metastatic tumors of renal and thyroid.
