[Clinical analysis of plasma cell granuloma occurred in head and neck]

To discuss the diagnosis and treatment of plasma cell granuloma in the head and neck region.

Retrospective analysis of 3 cases of plasma cell granuloma occurred in head and neck. One case treated with endoscopic surgery and nasal and oral steroids after operation. Two cases treated with Caldwell-Luc style resection, followed by oral steroids and radiotherapy, one of the two cases combined with chemotherapy simultaneously.

The patient done with endoscopic surgery followed up for 5 years, there was no tumor recurrence in the nasal cavity and maxillary sinus openings and sinus lining. Paranasal sinus CT was examed on the patient done with partial resection and radiotherapy 2 years after operation, no residual tumor proliferation. The third patient underwent paranasal sinus CT examination 3 years after operation, and no limitation of mouth opening was found.

The incidence rate of Plasma cell granuloma occured in head and neck is low. It is an inflammatory disease, but its physical signs and imaging findings are similar to malignant tumors. Because of the invasion feature, surgical resection should be the first choice, and if combined with radiotherapy and chemotherapy, the prognosis could be better.
