A case of adrenal cyst with an immunohistochemical evidence of mesothelial origin is presented. A 73-year-old Japanese woman was referred to our hospital with a complaint of left flank pain. The diagnosis of left adrenal cyst was made based on the radiographic and hormonal examinations. The adrenal cyst was removed surgically. Histological examination revealed that the cyst was lined with either a single layer of squamous or cuboidal cells. In immunohistochemistry testing, the cells were positive for keratin and carbohydrate antigen 125, while they were negative for epithelial membrane antigen, vimentin, desmin, and factor VIII related antigen. Thus, the present case was classified as epithelial cyst of mesothelial origin.

Elevated factor VIII level has recently been shown to be associated with increased risk of thrombosis. We report here a case of renal infarction in association with elevated factor VIII level. The patient presented with a three-day history of flank pain. Laboratory studies on presentation showed an elevated serum creatinine concentration and microscopic hematuria. He was found to have bilateral pulmonary emboli and left common femoral vein thrombosis; imaging studies showed evidence of renal arterial thrombosis with infarction. Hypercoagulability assessment showed an elevated factor VIII level. He was treated with heparin and warfarin with significant improvement in his renal function. Consideration should be given to measurement of factor VIII level as a part of the workup of unexplained thrombo-embolic events.

A man aged 69 years presented with acute right flank pain secondary to a hemorrhagic large adrenal tumor. En bloc resection was performed to repair the inferior vena cava. Immunoperoxidase levels in the tumor were positive for factor VIII and CD31 and negative for S100, protein Melan-A, CD34, synaptophysin, chromogranin, desmin, muscle specific actin, ETFA (EMA), KRT20 (CK20), CDX2, TTF1, LNPEP (PLAP), inhibin, ?-fetoprotein, CD30, hepatocyte paraffin, and aberrant expression of cytokeratin 7 and pankeratin. The pathological diagnosis was consistent with adrenal angiosarcoma. Obtaining appropriate immunoperoxidase stains and multidisciplinary evaluation helped make the diagnosis of this rare adrenal tumor and determine its management. The patient had an uneventful postoperative course and completed 4 cycles of adjuvant chemotherapy with doxorubicin/ifosfamide and adequately tolerated the treatment. However, positive surgical margins were found, so he was referred to radiation oncology specialists for possible adjuvant radiotherapy to the surgical bed. Weeks after the first initiation of therapy, the patient presented to the emergency department complaining of shortness of breath, fatigue, and generalized weakness for 3 days. He was admitted and found to have new-onset anemia and a new-onset, large, right pleural effusion. Thoracentesis performed showed sanguinolent fluid that, after microscopic evaluation, was suggestive of recurrent malignancy. Thoracic aortography performed with subselective catheterization to several arteries (right bronchial, right phrenic, and right renal arteries) did not show any active bleeding. However, the right inferior intercostal and adrenal arteries were presumed to be the reason for the bleeding event, so they were embolized until stasis. The patient remained hemodynamically unstable but eventually experienced multiorgan failure. In spite of aggressive measures, he died 10 days after admission to the hospital.
