Case Reports[Antiphospholipid antibody-associated hemophagocytic syndrome].
Autoimmune diseases such as systemic lupus erythematosus (SLE) are known to be causative disorders of reactive hemophagocytic syndrome (HPS). We recently encountered a case of HPS associated with the presence of antiphospholipid antibodies (aPL). This patient showed severe thrombocytopenia (0.2 x 10(4)/microliter) and moderate anemia (Hb; 7.6 g/dl). ⋯ In this patient, there is no possible causative factor of HPS (such as viral infection, lymphoma, and systemic lupus erythematosus) except the presence of aPL. There have been no previously reported cases describing the relationship between aPL and HPS. This case indicate that attention should be given to the possibility that certain patients with aPL-associated cytopenia may display accompanying intramedullary hemophagocytic phenomena.

Review Case Reports[Multiple renal infarction associated with lupus anticoagulant in a patient with systemic lupus erythematosus].
We report a rare case with multiple renal infarction associated with lupus anticoagulant and SLE. A 20-year old woman presented with remitent fever, butterfly rash and, abdominal pain. Laboratory findings showed leukopenia, positive antinuclear and anti-DNA antibodies, and biological false positive for syphilis. ⋯ She was treated with 80 mg of aspirin and have been in remission for two years. Although there have been reported 18 cases with renal infarction associated with antiphospholipid syndrome, this is the first report in Japan. Renal infarction should be differentiated from renal involvement in patients with SLE who have antiphospholipid antibodies.

Case Reports[Anterior ischemic optic neuropathy in a case of polyarteritis nodosa].
A 68-year-old male admitted to our hospital because of fever, body weight loss and multiple mononeuropathy. He developed visual loss in his right eye due to anterior ischemic optic neuropathy (AION). ⋯ Combination therapy of steroid (prednisolone 50 mg/day) and cyclophosphamide (50 mg/day) was started, which saved him from any other ischemic change including that of his left eye. As long as we know, AION occurring in PN is very rare, that is, only 4 cases have been reported in Japan.

Case Reports[A patient with acute sarcoidosis associated with fever, polyarthritis, and erythema nodosum: a typical of Löfgren's syndrome].
A 26-year-old female was admitted to Aoyama Hospital in February 1996, for evaluation of abnormal chest shadows and polyarthritis. She visited our clinic in December 1995 with complaints of fever, fatigue, and polyarthralgia which lasted for 3 weeks. Two weeks later she developed erythema nodosum on her lower legs with the exacerbation of polyarthritis. ⋯ This syndrome is common in Europe and is closely related to HLA-B8 and DR-3. The frequency of HLA-B8 and DR-3 in Japanese is almost 0%, explaining the rare onset of this syndrome in Japan. Our case is the second report of typical Löfgren's syndrome in Japan, although the patient did not have these HLA loci.
