Expression of MHC Class II antigens by oesophageal epithelium in herpes simplex oesophagitis.
An immunoperoxidase technique with monoclonal antibodies for the identification of lymphocyte subsets and MHC Class II antigens was applied to oesophageal biopsies from two patients with herpetic oesophagitis. Oesophageal epithelial cells were found to express the MHC Class II antigen. The inflammatory infiltrate of the lamina propria was composed of both B lymphocytes and T lymphocytes.

Renal macronodular tuberculoma: CT and MR findings in an asymptomatic patient.
We present the case of a 50-year-old man with a solitary mass lesion in the right kidney. Characteristics on ultrasound were a thick irregular hypoechoic wall and a slightly hyperechoic center. Computed tomography depicted the lesion as spontaneously hyperdense at its base. After administration of intravenous iodinated contrast only partial enhancement in the peripheral wall was seen. On MR imaging the lesion was hypointense on T1-weighted images, and T2-weighted images demonstrated a thick irregular hypointense peripheral wall and an intralesional fluid debris level. Gadolinium-chelates were not administered.
