[Solitary plasmocytoma of the mandible: study of a case].

The isolated plasmocytoma of the maxilla is an extremely rare tumor. It is classified in the group of low-grade B lymphomas. Its clinical and even radiological diagnosis remains difficult. Some authors, such as H.S. LOH in 1983, have attempted to regroup all reported cases in the literature, but many are incomplete, especially those which were first published. Most of the time, it is the pathological examination that rectifies the diagnosis and, currently, the immuno-chemical examination that confirms this diagnosis; this was demonstrated in the case reported here.
