Sporotrichoid lymphangitis due to group A Streptococcus.

We describe what is, to our knowledge, the first case of sporotrichoid lymphangitis caused solely by group A Streptococcus in an otherwise healthy patient. Infection with pyogenic pathogens, such as streptococci and staphylococci, as well as with the most common causes of sporotrichoid lymphangitis (i.e., Sporothrix schenkii, Nocardia brasiliensis, Mycobacterium marinum, and Leishmania species) should be considered in differential diagnosis for some patients.
