title: [Beneficial effects of CHOP therapy in a case of intravascular large B-cell lymphoma diagnosed by skin biopsy].
abstract: We report a case of intravascular large B-cell lymphoma. A 52-year-old man gradually developed dementia and abnormal behaviors, which were later accompanied by spastic paraplegia and sensory disturbance in his lower limbs. MR imaging of his brain showed high signal intensity lesions on T2 imaging. IMP-SPECT images of the brain showed diffuse reduction of radioisotope uptake. Many skin rashes that looked like senile hemangioma were observed on his body. Several of those were biopsied, and the diagnosis of intravascular large B-cell lymphoma was made because of malignant B lymphocytes filling the vessel lumens in one of the seven biopsy specimens. CHOP therapy was performed and found to be effective for the neurological disorders such as dementia, paraplegia, and sensory disturbance. Our case suggests that skin biopsy for more than one sample of the skin rashes is very important for the diagnosis of intravascular large B-cell lymphoma. CHOP therapy might be effective in this case because of early diagnosis by skin biopsy.
