Acute painless monocular visual loss due to central retinal artery occlusion in a patient with Churg-Strauss vasculitis.

Ocular involvement in Churg-Strauss syndrome (CSS) is infrequent. We describe a case of a 50-year-old woman, with blood eosinophilia, involvement of the respiratory tract, skin, and peripheral nervous system, fulfilling the American College of Rheumatology criteria for CSS, who presented with left foot drop followed by left acute painless visual loss. Central retinal artery occlusion was diagnosed by fundoscopic findings (retinal whitening with a cherry-red spot).

Blastic natural killer (NK)-cell lymphoma: report of an unusual CD4 negative case and review of the CD4 negative neoplasms with blastic features in the literature.

Blastic Natural Killer (NK)-cell lymphoma is a relatively new entity which has been recently included in the WHO classification. CD4 expression is observed in most cases of blastic NK-cell lymphomas and has been related with skin tropism. We report an unusual CD4 negative blastic NK-cell lymphoma with primary presentation in the skin, subsequent infiltration of the bone marrow and aggressive behavior.
