Nodular lymphangitis related to methicillin-resistant staphylococcus aureus infection.

Nodular lymphangitis, also known as lymphocutaneous syndrome or sporotrichoid lymphangitis, presents with inflammatory nodules along the lymphatic vessels, typically involving the upper or lower extremities. Although the most common cause of nodular lymphangitis is infection due to Sporothrix schenckii, Nocardia brasiliensis, Mycobacterium marinum, or Leishmania braziliensis, it is important for clinicians to be aware of methicillin-resistant Staphylococcus aureus as a rare cause of nodular lymphangitis and perform gram stain, bacterial culture, and antibiotic sensitivity profiles when appropriate. History of recent travel or exposures, incubation time, presence of systemic symptoms, and presence of ulceration, suppuration, or drainage can serve as diagnostic clues, but microbiological tissue cultures and histopathologic studies confirm the diagnosis. Herein, we present a case of nodular lymphangitis caused by methicillin-resistant Staphylococcus aureus (MRSA); tissue culture and antibiotic sensitivities were used to guide treatment.
