Granulomatosis with polyangiitis (GPA) is a systemic necrotizing granulomatous disease that involves small- and medium-sized arteries and affects the main respiratory tracts and kidneys. Upper respiratory tract involvement usually occurs in 90% of patients, who most frequently present with symptoms of chronic sinusitis. Subglottic stenosis (SS) is a rare and severe complication that is usually observed in approximately 15% of patients. Here we present a case of SS in a patient with limited form of GPA during remission. [ABSTRACT FROM AUTHOR]

Catastrophic antiphospholipid syndrome (CAPS) is a rare and fatal condition that is characterized by diffuse venous and/or arterial thromboembolism within a short period of time and histopathological confirmation of small-vessel occlusion in at least one organ or tissue in the presence of positive antiphospholipid antibodies. Here we report the case of a 19-year-old woman with CAPS. During the first week of her hospitalization, she was diagnosed with CAPS on the basis of skin necrosis, pulmonary artery thrombosis, cerebral venous sinus thrombosis, and positive lupus anticoagulant. She was treated with corticosteroids, intravenous immunoglobulins, plasmapheresis, and anticoagulants. Forty days after the onset of CAPS, cutaneous lesions were recurred during skin surgery. She required a high dose of corticosteroids, intravenous immunoglobulins, and rituximab. No further thrombotic events occurred. Rituximab may be an effective treatment option for patients with CAPS.

Thionamide induced vasculitis is a multisystem disease. The patients may present with different clinical signs and findings due to organ involvement. These patients are almost always perinuclear antineutrophil cytoplasmic antibody (pANCA) or antimyeloperoxidase (MPO) positive. Clinical findings are not seen in all of the patients who are ANCA positive while using thionamide. Although symptoms usually resolve with drug discontinuation, some patients, however, require high-dose steroids, immunosuppressants, or plasmapheresis. We present here a case of alveolar hemorrhage induced by propilthiouracil (PTU) during treatment with PTU for Graves'disease; patients completely recovered with corticosteroid, cyclophosphamide, and plasmapheresis.
