Spontaneous regression of an anaplastic large cell lymphoma in the oral cavity: first reported case and review of the literature.
Lymphomas account for 2-5% of all oral malignancies and are the third most common in this site. This case report appears to be the first in the world literature describing spontaneous regression in the oral cavity of a subset of non-Hodgkins lymphomas known as Ki-1 anaplastic large cell lymphomas (ALCL). Ki-1 ALCL account for 2-7% of all non-Hodgkins lymphomas and the clinical presentation is variable; they may arise de novo or in the setting of a separate primary lymphoma and commonly present in the extra-nodal location. Disease severity is also variable with waxing and waning lesions at one extreme which may spontaneously regress to bone marrow involvement in around 12% of cases. This case is especially interesting since the patient is a farmer, given the recent evidence that there may be a link between non-Hodgkins lymphoma and this occupation.
