A case of renal cell-like sinonasal adenocarcinoma: a rare entity

Renal cell-like sinonasal adenocarcinoma (RCLSA) is a rare entity and it is one of the variants of non-intestinal type sinonasal adenocarcinoma which arises in nasal cavity, paranasal sinuses and nasopharynx. This low-grade malignancy is characterised by neoplastic gland formation with monomorphic lesional cells displaying clear to eosinophilic  cytoplasm. The histological features of RCLSA are not specific to this entity; one is required to exclude primary and metastatic tumours which have a similar morphology.
