Angiotropic large cell lymphoma: simultaneous peripheral nerve and skeletal muscle involvement.

Angiotropic large cell lymphoma is a rarely encountered disorder characterized by a proliferation of malignant lymphoid cells within vascular lumina. Sites usually affected include the skin and central nervous system, although involvement of multiple other organ symptoms have been described including peripheral nerve and skeletal muscle. Simultaneous involvement of both skeletal muscle and peripheral nerve has rarely been reported. In most of those cases the diagnosis was made only at the time of autopsy. A case of an elderly male with angiotropic large cell lymphoma and in whom the diagnosis was made antemortem on a peripheral nerve and skeletal muscle biopsy is reported.
