Community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA) infection is a global problem of epidemic proportions. Many of the patients who develop CAMRSA skin lesions do not have infection-associated risk factors. Abscess, abscess with accompanying cellulitis, and cellulitis are the most common presentations of cutaneous CAMRSA infection; occasionally, these CARMSA-related lesions are misinterpreted as spider or insect bites. Other manifestations of cutaneous CAMRSA infection include impetigo, folliculitis, and acute paronychia.
The management of CAMRSA skin infection includes incision and drainage, systemic antimicrobial therapy, and adjuvant topical antibacterial treatment. In addition, at the initial visit, bacterial culture of the lesion should be considered. Direct skin-to-skin contact, damage to the skin surface, sharing of personal items, and a humid environment are potential mechanisms for the acquisition and transmission of cutaneous CAMRSA infection. Measures that strive to eliminate these causes are useful for preventing the spread of CAMRSA skin infection.

Community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA) infection is a clinical problem of increasing global incidence. CAMRSA most commonly presents as abscess and cellulitis of the skin and soft tissue. However, the lesions of cutaneous CAMRSA infection are pleomorphic and may appear as erythematous pustules of superficial folliculitis. This report presents the cases of 2 patients with CAMRSA skin infection that presented as a superficial folliculitis. The distribution of CAMRSA-related, erythematous, folliculocentric pustules was periumbilical, in contrast to the lesional location of methicillin-susceptible S. aureus (MSSA)-associated folliculitis, which typically appears on the axillae, bearded area, buttocks, and extremities. CAMRSA should be considered in the diagnosis of periumbilical folliculitis or superficial folliculitis arising in areas not typically affected by MSSA-related folliculitis, such as the chest, flanks, and scrotum.
