xlomafota13 shared this article with you from Inoreader Rare case of anaplastic plasmacytoma in the sinonasal tract Via Head & Neck Abstract Background Extramedullary plasmacytomas are tumors that develop from plasma cells and rarely express anaplastic features. To our knowledge, there have only been three reported cases of anaplastic plasmacytomas of the sinonasal tract in the English literature. We detail the fourth case. Methods A 70-year-old male was seen with a 4-month history of nasal congestion, bloody mucous, and left sided nasal obstruction. On positron emission tomography/computed tomography, the lesion was FDG-avid with an SUVmax of 25.1. A biopsy of the lesion and subsequent immunohistochemical staining confirmed the diagnosis of an anaplastic plasmacytoma. Results The patient is undergoing a 5-week course of curative-intent radiation therapy. Conclusion Extramedullary plasmacytomas with anaplastic features are very rare. We highlight the value of thorough histopathological review and detailed immunostains to arrive at a diagnosis of anaplastic extramedullary plasmacytoma. View on the web Inoreader.
