[Cutaneous infection caused by Mycobacterium chelonae. Presentation of 3 cases with multiple lesions]. / Infección cutánea por Mycobacterium chelonae. Presentación de tres casos con lesiones múltiples.

OBJECTIVE: To review the clinical, diagnostic, therapeutic and prognostic characteristics of cutaneous diseases caused by atypical mycobacteria and more specifically those by Mycobacterium chelonae. To improve our knowledge of this disease and its differential diagnosis with other cutaneous infections associated with folliculitis. DESIGN: Retrospective descriptive study. SETTING: Primary care and Dermatology specialty in a Health Center in the Madrid metropolitan area. PATIENTS AND OTHER PARTICIPANTS: The clinical records of non immunosuppressed patients, with multiple cutaneous lesions caused by Mycobacterium chelonae and confirmed by culture were reviewed. The evolution time, treatment regimes before diagnosis and possible epidemiological factors were studied. MEASUREMENTS AND MAIN OUTCOMES: Culture confirmed three non immunosuppressed patients with multiple lesions in both legs. Lesions had been present for longer than two months and had been treated with topical and systemic antibiotics with no improvement. The only relevant epidemiological finding was wax depilation. CONCLUSIONS: It is important to know the existence of this type of infection, since diagnostic suspicion allows for an early and efficient therapy which will present the emergency of important scars.

[Kawasaki's syndrome in the adult and bilateral sacroiliitis]. / Síndrome de Kawasaki del adulto y sacroileítis bilateral.

We present the case of a 23 year old patient with Kawasaki syndrome which resolved without sequelae after salicylate treatment. An peculiar finding was that of typical symptoms and signs of bilateral sacroiliitis demonstrated by symmetrically increased articular uptake of technetium 99 diphosphonate. This sacroiliitis disappeared completely after resolution of the syndrome. HLA-B27 ag was negative. Articular affection in Kawasaki syndrome comprises pain and/or swelling of large and small peripheral joints. Acute sacroiliitis is a finding not previously described. We believe this to have been an isolated episode and not the onset of a chronic seronegative spondylarthritis.
