1/7. Staphylococcal pyomyositis in a patient with non-Hodgkin's lymphoma.pyomyositis is a rare disease, encountered mainly in tropical climates. The diagnosis of this entity is difficult, if not misdiagnosed, because of its rarity and its subacute presentation. We report of a 42-year-old man, in whom pyomyositis developed while he was receiving the standard chemotherapy for T-cell non-Hodgkin's lymphoma (NHL). Three months following splenectomy, multiple abscesses occurred in the muscles of both thighs while the patient was receiving the third course of the CHOP regimen. A purulent exudate was aspirated from the abscesses under computed tomographic guidance. coagulase-positive Staphylococcus aureus was cultured in the aspirate. pyomyositis was completely resolved following the surgical drainage and the antistaphylococcal antibiotic treatment. This patient has shown that immunosuppression due to splenectomy, NHL, and chemotherapy, especially when using steroids, could be risk factors for pyomyositis in nontropical or semitropical countries.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/7. Focal myositis in monozygotic twins.Focal myositis is a rare disease with unknown etiology and a broad spectrum. Here, we present two cases in monozygotic twins who complained of recurrent pain of their calves and showed histological signs of inflammation and MRI image compatible with the diagnosis of focal myositis. The occurrence of twin cases not living in the same household suggests a genetic susceptibility to the disease.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/7. polymyositis presenting as a neck mass.polymyositis is a rare disease entity belonging to the class of enigmatic disorders known as the collagen vascular diseases. It is characterized by proximal muscle weakness. More than 50% of the patients with this disease have development of head and neck manifestations, most commonly a heliotrope rash or dysphagia. Weakness and atrophy of neck muscles, and lolling of the neck have also been described. We report a case of polymyositis presenting as a neck mass, a heretofore undescribed manifestation of this disease in the head and neck. A review of the literature and an interdisciplinary approach to the diagnosis and management of this unusual disease will be described.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/7. Community-acquired methicillin-resistant staphylococcus aureus pyomyositis in an intravenous drug user.pyomyositis is a disease of abscess formation deep within large striated muscles. Outside of the tropics it is a rare disease which occurs mainly in certain patient populations such as the immunosuppressed or intravenous drug users (IDUs). A case of community-acquired methicillin-resistant staphylococcus aureus (CA-MRSA) pyomyositis in an IDU is described. The incidence of both CA-MRSA and pyomyositis is currently increasing. To the authors' knowledge this is the first reported case of CA-MRSA pyomyositis in the UK. Cases of CA-MRSA pyomyositis are likely to increase and it may be necessary to empirically treat certain patients with glycopeptides.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/7. Desmoplastic fibroma: report of a case with proliferative myositis.Desmoid tumor of the mandible, or desmoplastic fibroma, is a rare disease with only a few cases reported in the literature. This paper presents the rare case of an elderly male with desmoplastic fibroma of the mandible with an uncommon accompanying proliferative myositis. The case is discussed with emphasis on the clinical presentation, differential diagnosis and treatment of this lesion.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/7. polymyositis/dermatomyositis associated with dermatitis herpetiformis.We describe 2 patients with dermatitis herpetiformis who developed polymyositis/dermatomyositis. On HLA typing, both patients were found to be HLA-B8, DR3 positive. The concurrence of these two relatively rare diseases, both associated with immunologic abnormalities, further supports the role of autoimmunity in their pathogenesis and indicates a possible common genetic basis. It also suggests that myositis may be more common in patients with dermatitis herpetiformis than in the general population.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
7/7. pyomyositis tropicans: a diagnostic dilemma.pyomyositis tropicans is a rare disease in non-tropical climates and thus presents diagnostic difficulties. Two children with single staphylococcal psoas muscle abscesses were recently successfully treated. Computerized axial tomography was found to be a useful diagnostic aid, allowing exact localization of the lesion. The diagnosis and therapy of these abscesses are discussed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
