1/4. osteomyelitis and skin ulcers caused by Mycobacterium szulgai in an AIDS patient.Mycobacterium szulgai is a ubiquitious non-tuberculous mycobacterium causing infection in immunocompetent and immunocompromized patients. Clinically mimicking pulmonary tuberculosis in most cases described, rarely other manifestations occur. Here we report the case of an AIDS patient with osteomyelitis of the hand and toe, accompanied by multiple cutaneous ulcers of the chest and forearm. The case highlights the unusual combination of osteomyelitis and skin ulcers without pulmonary infection and describes the likely cutaneous route of infection in a patient who keeps tropical fish.- - - - - - - - - - ranking = 1keywords = mycobacterium (Clic here for more details about this article) |
2/4. Unusual mycobacteria in 5 cases of opportunistic infections.Five cases of infection due to an unusual mycobacterium are recorded, and the growth requirements and histological findings are discussed. On initial culture, these mycobacteria could be grown only on Lowenstein-Jensen medium containing ferric ammonium citrate, and the histology of the skin lesions was not always typical of mycobacterial disease.- - - - - - - - - - ranking = 1keywords = mycobacterium (Clic here for more details about this article) |
3/4. mycobacterium kansasii infection in a patient presenting with porphyria cutanea tarda.mycobacterium kansasii, an atypical mycobacterium, is an uncommon cause of cutaneous and joint disease in immunocompetent patients. We report an unusual case of infection with this organism in a patient who initially presented with porphyria cutanea tarda (PCT), and who was noted also to have a crusted ulcer over the middle phalanx and swelling of the proximal interphalangeal joint of the right middle finger. The cutaneous ulcer healed with minocycline, but the joint disease required a combination of rifampicin and ethambutol before a therapeutic response was obtained.- - - - - - - - - - ranking = 1keywords = mycobacterium (Clic here for more details about this article) |
4/4. A case of pustular ulcerative dermatosis of the scalp associated with ulcerative skin lesions on the scrotum.A 79-year-old man developed pustules, erosions, and ulcer with severe pain on the parietal regions of the scalp and the scrotum. In another hospital, mycobacterium was detected from the pustules of the scalp at Gaffky scale 1, and this patient was referred to our clinic. In our hospital, repeated cultures of the pus from the skin lesions of the scalp were negative for mycobacterium. biopsy specimens obtained from the skin lesions on the scalp disclosed ulcerative granulation with infiltration of inflammatory cells. Antibiotics and antituberculotic agents were ineffective. In contrast, the ulcerative skin lesions on the scalp and scrotum responded well to topical and systemic glucocorticosteroids. Although this patient developed pustular ulcerative skin lesions not only on the scalp but also on the scrotum, we considered this case to be pustular ulcerative dermatosis of the scalp developing ulcerative skin lesions on the scrotum.- - - - - - - - - - ranking = 2keywords = mycobacterium (Clic here for more details about this article) |
