Angiotropic lymphoma: proliferation of B cells in the capillaries of cutaneous angiomas

We report a 52-year-old patient with cutaneous angiomas on the trunk in ass ociation with angiotropic lymphoma involving the nervous system. The lesion al skin showed proliferation of atypical B cells in the capillaries. The di agnosis of angiotropic lymphoma with neurological deficits is often difficu lt before death. Thus, skin biopsy in this case proved to be diagnostic of the central nervous system disease without the risk of brain biopsy. The di agnosis of angiotropic lymphoma in the future may be achievable by biopsy o f coincidental angiomas.
