Atypical mycobacterial cervical lymphadenitis associated with Sweet's syndrome

We report the case of a 52-year-old woman with a non-tuberculous (atypical) mycobacterial cervical lymphadenitis, caused by Mycobacterium fortuitum, in association with Sweet's syndrome. The cervical lymphadenitis was resistant to medical treatment, and the Sweet's syndrome occurred intermittently. Systemic steroid treatment was required to control the cutaneous symptoms.
