Sonographic findings in Nicolau syndrome following intramuscular diclofenac injection: A case report.
Summary of "Sonographic findings in Nicolau syndrome following intramuscular diclofenac injection: A case report."
Nicolau syndrome (also known as embolia cutis medicamentosa and livedoid dermatitis) is a rare but severe localized adverse drug reaction of intramuscular injection of various drugs. The typical presentation is pain around the injection site soon after injection, followed by erythema, livedoid patch, hemorrhagic patch, and finally necrosis of skin, subcutaneous fat, and muscle tissue. We report a case that occurred in a 34-year-old woman after intramuscular injection of diclofenac sodium. Sonography showed diffuse thickening with increased echogenicity of the skin and subcutaneous fat layer, while MRI revealed extensive edema involving gluteal and piriformis muscles and deep fascia, and fluid collection. © 2010 Wiley Periodicals, Inc.

Medical and Biotech [MESH] Definitions
Medroxyprogesterone Acetate
A synthetic progestin that is derived from 17-hydroxyprogesterone. It is a long-acting contraceptive that is effective both orally or by intramuscular injection and has also been used to treat breast and endometrial neoplasms.
Diclofenac
A non-steroidal anti-inflammatory agent (NSAID) with antipyretic and analgesic actions. It is primarily available as the sodium salt.
Mobius Syndrome
A syndrome of congenital facial paralysis, frequently associated with abducens palsy and other congenital abnormalities including lingual palsy, clubfeet, brachial disorders, cognitive deficits, and pectoral muscle defects. Pathologic findings are variable and include brain stem nuclear aplasia, facial nerve aplasia, and facial muscle aplasia, consistent with a multifactorial etiology. (Adams et al., Principles of Neurology, 6th ed, p1020)
Nijmegen Breakage Syndrome
A chromosome instability syndrome resulting from a defective response to DNA double-strand breaks. In addition to characteristic FACIES and MICROCEPHALY, patients have a range of findings including RADIOSENSITIVITY, immunodeficiency, increased cancer risk, and growth retardation. Causative mutations occur in the NBS1 gene, located on human chromosome 8q21. NBS1 codes for nibrin, the key regulator protein of the R/M/N (RAD50/MRE11/NBS1) protein complex which senses and mediates cellular response to DNA DAMAGE caused by IONIZING RADIATION.
Neuritis, Autoimmune, Experimental
An experimental animal model for the demyelinating disease of GUILLAINE-BARRE SYNDROME. In the most frequently used protocol, animals are injected with a peripheral nerve tissue protein homogenate. After approximately 2 weeks the animals develop a neuropathy secondary to a T cell-mediated autoimmune response directed towards the MYELIN P2 PROTEIN in peripheral nerves. Pathologic findings include a perivascular accumulation of macrophages and T lymphocytes in the peripheral nervous system, similar to that seen in the Guillaine-Barre syndrome. (From Adams et al., Principles of Neurology, 6th ed, p1314; J Neuroimmunol 1998 Apr 1;84(1):40-52)
