Myeloma involving the laryngeal cartilage is rare, whereas extramedullary plasmacytoma involving only the thyroid cartilage is even rarer. No case of de novo extramedullary plasmacytoma involving thyroid cartilage has been published so far. Hence, it was a diagnostic challenge for clinicians, radiologists, and pathologists. Here, we presented a case of a 61-year-old man who had fixed right laryngeal swelling. After 18 F-FDG PET/CT, biopsy, and myeloma workup, it was found to be plasmacytoma involving the right thyroid cartilage lamina. This case highlighted the rarity of this presentation and the importance of keeping in mind this differential to lead toward diagnosis.
累及喉软骨的骨髓瘤较为罕见，而仅累及甲状软骨的髓外浆细胞瘤则更为罕见。迄今尚未有关于初发的累及甲状软骨的髓外浆细胞瘤的报道。因此，这对临床医生、放射科医生和病理学家来说是一个诊断上的挑战。在此，我们报告了 1 例 61 岁男性患者，其右侧喉肿胀固定。行 18 F-FDG PET/CT、活检和骨髓瘤检查后，发现右侧甲状软骨板有浆细胞瘤累及。本例强调了这种表现的罕见性，以及牢记这种鉴别诊断以进行诊断的重要性。
