Malignancies arising in oncocytic schneiderian papillomas: A report of 2 cases and review of the literature

Archives of Pathology & Laboratory Medicine, Oct 2001 by Maitra, Anirban, Baskin, Leland B, Lee, Edward L

In conclusion, we report 2 additional cases of malignancies arising in OSPs, including the first case of a synchronous SCC and the third case of a synchronous SNUG A small biopsy specimen from an OSP may at times only show foci of dysplastic epithelium or carcinoma in situ, with invasive carcinoma being revealed in the subsequent resection specimen. Therefore, pathologists need to stress the requirement for complete excision and thorough sampling of these benign tumors so as not to miss a coexistent carcinoma.
