Hello and welcome to HCM,
is primary malignancy arising from the lymph nodes.
The lymphoma can spread to surrounding soft tissue
Thus, the lymphoma detected in the soft tissue of the mandible is actually the lymphoma arising in the lymph node involving the adjacent soft tissue.
The treatment of the lymphoma involving the lymph node as well as the adjacent soft tissue is similar to lymphoma involving the lymph node alone.
Involement of other lymphoid tissues at distant sites should also be sought as this involvement determines the stage of the disease.
Thanks and take care
