To determine some of the key clinical features that help prompt clinicians to pursue additional work-up for evaluation of CNS involvement of MF, we conducted a systematic review to better define characteristics, treatments, outcomes, and mortality in these patients. Our analyses indicated that neurologic surveillance after the diagnosis of MF is crucial. Review of systems should include change in mentation, vestibular, and ocular symptoms. Progression to CNS involvement does not always occur in tandem with cutaneous disease burden. Single-agent therapies can delay disease progression and improve prognosis. Multi-agent treatment does not improve survival.

Thinking about CNS Metastasis in Cutaneous Lymphoma: Analysis of Existing Data

Purpose. To report a case of anaplastic large cell lymphoma (ALCL) of the central nervous system (CNS) producing an optic neuropathy. Methods. Observational case report. Results. A 29-year-old male presented with new onset headaches. Magnetic resonance imaging (MRI) of the brain revealed a large enhancing parietal lobe mass. Ocular exam at that time was normal. Initial diagnoses included possible bacterial cerebritis and fungal abscess. Serial lumbar punctures showed increased white blood cells but cytology was negative. A brain biopsy was non-diagnostic. The patient then presented with a left optic neuropathy. Repeat MRI of the brain and orbits revealed infiltration of the clivus and left orbital apex including the optic nerve. The patient had elevated liver function studies and an abdominal ultrasound disclosed two hypoechoic lesions. Liver biopsy confirmed the diagnosis of ALK-1 positive ALCL. The patient was treated with chemotherapy but expired seven months after the initial presentation. Conclusion....

Optic neuropathy due to anaplastic large cell lymphoma

Central nervous system involvement by mycosis fungoides (MF) is rare and is usually seen in advanced stages of the disease. We describe a patient with early-stage follicular MF who presented with changes in mental status. Despite an initial diagnosis of vasculitis based on clinical and brain biopsy results, the postmortem examination revealed extensive infiltration of MF cells throughout the brain with leptomeningeal involvement. This case in addition to the accompanied review of literature illustrates the importance of the awareness of central nervous system involvement by MF and highlights the need for an urgent neurologic evaluation in patients with a history of MF now presenting with neurologic signs or symptoms.
