RESUMO
Methicillin-resistant Staphylococcus aureus (MRSA) has recently emerged as a cause of community-acquired infections among individuals without risk factors. Community-associated MRSA (CA-MRSA) appears to be more virulent, causing superficial mild skin and soft tissue infections to severe necrotizing fasciitis, and in rare cases, pneumonia. Community-associated MRSA was first reported in Australia in the early 80s, after almost two decades in the USA, and then in several countries in Europe, Asia and South America. No data exists in Portugal. We report the first case of CA-MRSA infection in Portugal, in a young adult with severe necrotizing pneumonia, complicated with bilateral empyema and respiratory failure.

Pityriasis rotunda is an uncommon cutaneous disorder consisting of asymptomatic, strikingly circular, scaly lesions on the trunk and extremities, with the histologic appearance of ichthyosis vulgaris. Previous cases have been described in Japanese, South African, and West Indian persons, usually in association with an underlying serious systemic disease. A case of pityriasis rotunda in a 32-year-old black man in whom no diagnosable disorder could be demonstrated is presented.
