title: Macrophage-dominant sialadenitis in human T-cell leukemia virus type I-associated myelopathy after living-donor liver transplantation.
abstract: A 64-year-old man who suffered from human T-cell leukemia virus type I (HTLV-I)-associated myelopathy (HAM) after living-donor liver transplantation (LDLT) for liver cirrhosis due to hepatitis C virus infection complained of xerostomia. Although exocrine function test results were positive, autoantibodies including anti-SS-A/SS-B antibodies and sialography showed negative findings. Labial salivary gland biopsy revealing infiltration of 60 counts of mononuclear cells (MNCs) in minor salivary glands led to a diagnosis of Sjögren's syndrome-like sialadenitis. Immunohistochemistry demonstrated dominant CD68 staining and major histocompatibility complex class II on the surface of infiltrating MNCs. Herein we have reported a rare condition of macrophage-dominant sialadenitis in a patient with HAM after LDLT.
