Secondary Membranous Nephropathy with Salivary Gland Cancer / 대한신장학회지

We report here on a rare case of membranous nephropathy occurring concurrently with salivary gland cancer. A 67-year-old woman was admitted to our department for nephrotic syndrome. She was diagnosed with membranous nephropathy and this was initially managed with steroids and cyclophosphamide, which started in 2003 and continued for about 10 months, without deriving any therapeutic benefits. During the treatment, the patient was diagnosed with salivary gland cancer when an incidental salivary gland mass was discovered in 2005. The patient's urinary protein level began to decrease following resection of the malignant mass. The clinical findings represent an interesting case of secondary membranous nephropathy that was diagnosed prior to the incidental discovery of malignancy.

Kaposi Sarcoma in Patient with Membranous Glomerulonephropathy during Corticosteroid Therapy / 대한신장학회잡지

Membranous glomerulonephropathy is a common cause of nephrotic syndrome in adults. Kaposi sarcoma is a well-known entity with distinct clinical forms such as nodular cutaneous lesions, generalized lymphadenopathy and visceral involvement. Incidence of Kaposi sarcoma is greater in patients with immunosuppression, particularly those having undergone renal transplantation, but also in patients with other underlying disorders treated with immunosuppressive therapy, notably, corticosteroids. We present a case of Kaposi sarcoma in patient with membranous glomerulopathy during corticosteroid therapy. A 49- year-old man was admitted with a complain of facial and leg edema, 5-kg weight gain for 1 month, and foamy urine. Kidney biopsy showed membranous glomerulopathy. We started corticosteroid therapy to the patient. Two month later, his 24 hr urinary protein was decreased to 2.1 g/day. But, the well defined, various-sized, purple-colored papules and plaque appeared on the both hands and feet. He underwent skin biopsy, which revealed abnormally proliferated and dilated vessels, vascular slits, spindle-shaped cells and extravasated erythrocytes in the dermis. The findings were in accordance with Kaposi sarcoma. So he received cryotherapy with discontinuing corticosteroid. Four months after cryotherapy, skin lesions were cleared leaving slight hypopigmentation and amount of proteinuria was preserved without definite aggravation.

A Case of Membranous Glomerulonephropathy Associated with Idiopathic Autoimmune Thrombocytopenic Purpura / 대한신장학회잡지

Membranous glomerulonephropathy is the most common cause of nephrotic syndrome in adults and idiopathic autoimmune thrombocytopenic purpura is autoimmune disease caused by autoantibody to platelet membrane glycoprotein. Although there are some pathologic similarity between two diseases that 'membrane attack complex' play a role in pathologic process, but only 3 cases worldwide are reported about membranous glomerulonephropathy associated with idiopathic autoimmune thrombocytopenic purpura. So we report a case of sixty eight years of woman who had symptoms of generalized edema, foamy urine, anorexia and thrombocytopenia on admission and developed more severe symptomatic thrombocytopenia there after. She was diagnosed membranous glomeulonephropathy on renal biopsy and also diagnosed idiopathic autoimmune thrombocytopenic purpra on bone marrow biopsy and on the basis of exclusion.
