Marginal zone B-cell lymphoma of the infratemporal fossa: a rare case and review

Although it represents the second most common neoplasm of the head and neck, lymphoma is generally not surgically managed and thus may be less familiar to otolaryngologists than other malignancies. However, otolaryngologists are often involved in the initial diagnosis, and should be aware of unusual presentations and the main lymphoma subtypes. We present a case of an extranodal marginal zone B-cell lymphoma, an indolent non-Hodgkin's lymphoma subtype. This type of lymphoma most commonly occurs in the stomach, but was found in the infratemporal fossa. This is the first report of an extranodal marginal zone B-cell lymphoma occurring in this location.
