The use of cyclophosphamide and rituximab for patients with refractory myasthenia gravis has shown promising results. We report on a 31-year-old Chinese woman with acetylcholine receptor antibody-negative and muscle-specific tyrosine kinase antibody-positive generalised myasthenia gravis who had refractory bulbar dysfunction and respiratory failure despite immunosuppressive therapy and thymectomy, and partial and sustained responses to cyclophosphamide and rituximab treatment, respectively. Myasthenia crisis was diagnosed when she presented in the third trimester of pregnancy with dysphagia, bilateral ptosis, prominent fatigability, and respiratory failure. She required prolonged intensive care and non-invasive ventilatory support despite several courses of intravenous immunoglobulins and plasmapheresis. Pulse cyclophosphamide 500 mg/m(2) was given monthly for 4 consecutive months with a partial response. Rituximab 500 mg weekly was subsequently given for 4 weeks with a dramatic and sustained response. She remained symptom-free and assumed full maternal care at 1 year. To the authors' knowledge, this is the first report of a Chinese patient with refractory myasthenia gravis who responded to cyclophosphamide and rituximab.

T-cell prolymphocytic leukemia (T-PLL) is an aggressive mature T cell neoplasm that typically involves peripheral blood, bone marrow, lymph nodes and spleen. It is a rare disease that comprises 2-5% of mature lymphocytic leukemia in adults. Here we present a T-PLL patient with CNS involvement. A 74-year-old man admitted to a hospital in April 2014 with vomiting. He was diagnosed as chronic lymphocytic leukemia (CLL) and R-CVP (Rituximab, cyclophosphamide, vincristine and prednisolone) chemotherapy protocol was started. After the first two cycles of chemotherapy, the patient's mental functions improved. However after the 3(rd) cycle of chemotherapy was given in July 2014 the general situation of the patient deteriorated and ptosis of the left eye and facial paralysis developed. Then the patient was referred to our medical center. An MR of the brain revealed linear contrast enhancement around the bilateral 3(rd), 7(th) and 8(th) cranial nerves which indicated cranial involvement by the lymphoproliferative process (Figure 1). Cerebrospinal fluid cytological examination confirmed the diagnosis. Based on these and bone marrow aspiration and biopsy findings a diagnosis of T-PLL was rendered (Figure 3). In September 2014 the patient died suddenly due to a cardiac arrest. Differential diagnosis is very important in T-PLL. Both T-PLL and chronic lymphocytic leukemia (CLL) may present with splenomegaly and lymphocytosis as well as circulating prolymphocytes in blood. Typical CLL cells are like mature lymphocytes with dense nucleus and aggregated chromatin. To conclude, CNS involvement in T-PLL is a rare finding and differential diagnosis of T-PLL is very important.

We herein report a case of granulomatosis with polyangiitis in a 73-year-old man. He had experienced bilateral ptosis, redness of both eyes, right facial weakness, and hearing loss in the right ear for two months. Myeloperoxidase anti-neutrophil cytoplasmic antibody was positive. Corticosteroids and intravenous cyclophosphamide pulse therapy yielded a response. After the fourth pulse of cyclophosphamide, he developed headache, diplopia, restricted left eye movement, right facial palsy, and hearing loss in the right ear. A one-year remission period was achieved by increasing the steroid and rituximab doses. Rituximab was effective against the relapse of granulomatosis with polyangiitis and cranial neuropathy.
