What other organisms may present with lymphocutaneous disease?

Several other diseases may present with a distal ulcer, proximal secondary nodules along the lymphatics, and regional lymphadenopathy. The most important organisms include nontuberculous Mycobacterium (Mycobacterium marinum, Mycobacterium kansasii, Mycobacterium fortuitum complex), Nocardia, leishmaniasis, cat scratch disease, and tularemia. A patient with this clinical presentation should have tissue biopsies for routine histology and cultures to include bacteria, mycobacteria, and fungi. This pattern of disease is also called sporotrichoid.
