A case of solitary plasmacytoma of the mastoid bone presenting as coalescent mastoiditis

Abstract

Squamous cell carcinoma, lymphoma, plasmacytoma and metastatic tumors can be seen in the mastoid bone as is the case with prostate or lung tumor. Plasmacytomas are rarely seen plasma cell tumors of the mastoid bone. In this case presentation, a 34-year-old patient who applied to our hospital with mastoiditis symptoms, who had undergone mastoidectomy and diagnosed with localized plasma cell lambda monoclonal neoplasia of mastoid bone was presented. Malignancies such as solitary plasmacytoma should be kept in mind and pathological evaluation of surgery materials should be remembered in the differential diagnosis of coalescent mastoiditis. Otherwise, treatment will be inevitably inadequate. © 2018, Logos Medical Publishing. All rights reserved.
