It can cause diseases in immunocompetent patients, usually resulting in localized skin and soft tissue infections. Cervical lymphadenitis caused by M. fortuitum is rare. We report a 46-year-old woman in whom skin lesions of cutaneous polyarteritis nodosa, leucocytoclastic vasculitis and Sweet's syndrome had successively developed before the diagnosis of cervical lymphadenitis caused by M. fortuitum was made. The skin lesions responded to colchicine and systemic corticosteroids but recurred intermittently. After establishment of the diagnosis, she received treatment with clarithromycin and ciprofloxacin. The cervical lymph nodes decreased in size 6 months later and no more new skin lesions were found.[SDGs]SDG3ciprofloxacin; clarithromycin; colchicine; corticosteroid; acute febrile neutrophilic dermatosis; adult; article; bacterial growth; case report; cervical lymph node; comorbidity; connective tissue disease; female; granulomatous inflammation; human; inflammatory infiltrate; leukocytoclastic vasculitis; lymphadenitis; Mycobacterium fortuitum; polyarteritis nodosa; priority journal; skin blood vessel disorder; skin disease; skin infection; soft tissue infection; vasculitis; Female; Humans; Middle Aged; Mycobacterium fortuitum; Mycobacterium Infections, Atypical; Polyarteritis Nodosa; Skin Diseases, Bacterial; Sweet's Syndrome; Tuberculosis, Lymph Node; Vasculitis, Hypersensitivityjournal article10.1111/j.1365-2133.2004.06201.x155410942-s2.0-9644303189
