Ethynylthioamide Complexes: Synthesis, Reactivity and an Unusual Coupling Reaction with Diethylaminopropyne
The reaction of [(CO)5Cr(THF)] with propynethioic acid amides, R–C≡C–C(=S)NMe2 (R = H, SiMe3), yields the thioamide complexes [(CO)5Cr–S=C(NMe2)C≡C–H] (1a) and [(CO)5Cr– S=C(NMe2)C≡C–SiMe3] (1b). Treatment of solutions of 1a or 1b with methyllithium generates, via deprotonation or desilylation, the lithium salt Li[(CO)5Cr–S=C(NMe2)C≡C] (2). On filtration over silica, 2 is readily reprotonated. ...

Mycosis fungoides with an unusual clinicopathological presentation
It is a challenging task to diagnose mycosis fungoides (MF), a type of primary cutaneous lymphoma, in the early stages of its development, due to the unspecific presentations associated with the disease. Histopathology and immunohistochemistry conduce to a more definite diagnosis. Presence of atypical T-cells in epidermis and upper dermis is the most significant pathologic finding. Herein...
متن کاملAn Unusual Presentation of Granulomatosis with Polyangiitis
The granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a pauci-immune vasculitis involving small- and medium-sized blood vessels. Classically, the patients inflicted with this disease present with a triad of necrotizing granulomatous inflammation of the respiratory tract, cutaneous necrotizing vasculitis, and glomerulonephritis (GN). The antinuclear (ANA) and...
متن کاملAn Unusual Case of Hepatosplenomegaly with Cytopenia
Autoimmune lymphoproliferative syndrome (ALPS) is a rare, inherited disorder of immune dysregulation secondary to defective lymphocyte apoptosis. This leads to uninhibited proliferation of lymphoid tissue manifesting with lymphadenopathy, hepatosplenomegaly, autoimmune cytopenia, and an increased risk of lymphoid malignancy. We report a 2 year old boy with fever, generalized lymphadenopathy, he...
