Antitumor necrosis factor therapies have revolutionized the treatment of some inflammatory diseases. However, the use of these agents is associated with the development of many paradoxical autoimmune diseases. Less well-recognized is the association with sarcoidosis. We report a 55-year-old female with long-standing ankylosing spondylitis who developed persistent dry cough and dyspnea while receiving etanercept therapy. High-resolution computed tomography scanning showed mediastinal lymphadenopathy and multiple nodules in both lung fields developed two months after the administration of etanercept. Lymph node biopsy was not practicable. Histopathological examination of minor salivary gland biopsy revealed noncaseating granulomata, and the serum angiotensin-converting enzyme was very elevated. All infectious studies were negative. Etanercept was discontinued plus a course of corticosteroids with a clinical improvement, and a follow-up high-resolution computed tomography scanning 4 months later showed evident regression of mediastinal lymph nodes and pulmonary nodules. Potential pathogenic mechanisms of this paradoxical effect of tumor necrosis factor-alpha blocking agents are discussed.
ABSTRACT
Behçet's disease is a systemic vasculitis of unknown etiopathogenesis. Arterial events such as pseudo-aneurysms are rare and may be the mode of occurrence of the disease. These pseudo-aneurysms tend, regardless of size, to progress rapidly to life-threatening rupture. We report two cases of arterial pseudo-aneurysms that ruptured. Treatment consisted of surgical repair in one case and arterial ligation in the other; the postoperative course was uneventful in both cases.

Melanotic progonoma is a rare tumor that primarily affects the maxilla of infants during the first year of life. Involvement in the skull is rare and can mimick other benign or malignant tumors affecting the infant's skull. The authors report a case of melanotic progonoma of right occipital and temporal bones in a 7-months' girl and discuss the histological features, immunohistochemistry study, differential diagnosis and management of this tumor.
