Abstract Solitary plasmocytoma is a rare tumour that belongs to the myeloid dysplasia group. The authors present an unusual evolution of this pathology through a clinical case. A 42-year-old patient was diagnosed with solitary nasosinusal plasmocytoma following biopsy of the right nasal fossa process; several weeks after this the tumour spontaneously regressed. Extramedullar plasmocytoma is a myeloid dysplasia that seldom evolves into multiple myeloma. Spontaneous regression has been described for some malignancies, implying immunological factors, but not previously for extramedullary plasmocytoma.
