Abstract

Extramedullary solitary plasmacytomas are very rare entities representing only 3% of all plasma cell malignancies, and with a clear male predominance. All tissues can be affected, but the most frequent locations are the head and neck, lungs, and gastrointestinal tract. While not the rarest entity, solitary plasmacytomas still represents a small minority of nasopharyngeal malignancies: 4–6.2%. We report an original case of solitary extramedullary plasmocytoma of the nasopharynx in a 76-year-old Tunisian woman with no significant past medical history investigated for nasal obstruction, vertigo, and upper (oropharyngeal) dysphagia that had been progressing for approximately two months. As rare as it is, this diagnosis should, however, be considered in the differential diagnosis for any nasopharyngeal tumor.
