ABSTRACT
Cutaneous alternariosis is a rare condition, caused by an uncommon opportunistic pathogen. The most frequently affected individuals are immunosuppressed patients, e.g., organ transplant patients on immunosuppressive therapy. Clinical manifestations range from local skin lesions to disseminated disease. We present a case report of cutaneous alternariosis in a renal transplant recipient, confirmed by histological examination and molecular means. In addition, a review of the literature was performed.

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.

We present a case of cerebral amyloidoma in a 71-year-old woman. The clinical presentation and the radiological features were both highly suggestive for a brain tumor.

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.
