Catastrophic antiphospholipid syndrome and heparin-induced thrombocytopenia-related diseases or chance association?

Antiphospholipid syndrome (APS) and heparin-induced thrombocytopenia (HIT) are thrombotic disorders due to specific autoimmune-mediated antibodies. Catastrophic APS (CAPS), also known as Asherman's syndrome, is a life-threatening severe form of APS. Diagnostic criteria for CAPS include the development of a thrombotic event of three or more organs in less than a week with the presence of antiphospholipid antibodies and microvascular thrombosis on histology.

Atypical presentation of carcinoid tumor with unresolved right shoulder pain: a case report.

Introduction: Carcinoid tumors are variants of neuroendocrine tumors that typically arise from the gastrointestinal tract and the bronchus, but they can involve any organ. Unresolved right shoulder pain manifesting as the first clinical presentation of carcinoid tumor with unknown primary origin is a rare clinical entity. To the best of our knowledge, herein we present the first case report describing metastasis to the right shoulder joint in a patient who presented with bone pain as the first clinical manifestation of metastatic carcinoid tumor of unknown primary origin.

An unusual cause of pancytopenia: Whipple's disease.

Whipple's disease is a systemic infectious disease caused by the bacteria Tropheryma whipplei. The most common clinical manifestations of Whipple's disease are weight loss (92%), hypoalbuminemia and steatorrhea (91%, respectively), diarrhea (72%), arthralgia (67%), and abdominal pain (55%). Neurological signs and symptoms from dementia to oculomasticatory myorhythmia or oculofacioskeletal myorhythmia (pathognomonic of Whipple's disease), lymphadenopathy, and fatigue can also be present.

Unusual Course of Splenic Marginal Zone Lymphoma.

A 53-year-old woman was diagnosed with splenic marginal zone lymphoma by pathological examination on left submandibular lymph node and bone marrow biopsies and markedly enlarged spleen. Four cycles of Rituximab chemotherapy were given. Seven months after finishing Rituximab chemotherapy, she developed left upper extremity swelling without evidence of deep venous thrombosis.
