Malignant lymphoma in unusual areas of the head and neck: parapharyngeal space and temporal fossa.
Primary malignant lymphomas of the parapharyngeal space are rare and only 28 cases are known to have been reported. No case of malignant lymphoma arising in the temporal fossa has been previously documented. The present paper reports a case of primary non-Hodgkin's lymphoma of the parapharyngeal space in a child and two cases of lymphoma of the temporal fossa in adults. All three cases were diagnosed histopathologically from biopsy specimens as diffuse, B-cell lymphomas. For diagnosis, inspection and bimanual palpation were most important in the parapharyngeal case and the temporal cases required more than one biopsy for the final diagnosis.
