Sporotrichoid skin lesions have a characteristic lymphangitic spread with nodules that ascend proximally along lymphatic vessels.
DISEASE CHARACTERIZATION Sporotrichosis Nocardiosis (brasiliensis) Coccidioidomycosis Streptococcus Pasteurella tularensis Atypical mycobacteria such as Mycobacterium marinum and M kansasii, as well as Pasteurella tularensis and Nocardia brasiliensis can also cause sporotrichoid infections.2-5 These infections may suffer the same difficulties in diagnosis as sporotrichosis.
SPECIAL STAINS/IMMUNOPEROXIDASE/OTHER CHARACTERIZATION Immunoperoxidase Utility of anti-bacillus Calmette-Guérin antibodies as a screen for organisms in sporotrichoid infections
J Am Acad Dermatol 2001;44:261-4
Thirteen specimens of suspected sporotrichosis were selected for staining with anti-BCG antibody
Sporotrichoid infection was confirmed by histochemical staining, biopsy, and follow-up results
Results: Twelve of the 13 specimens stained positively using anti-BCG antibody
Of the 5 cultures done, 2 were positive for M marinum, and 1 grew Sporothrix schenckii.
Conclusion: Immunohistochemical staining with anti-BCG antibody offers another screening method to identify organisms in sporotrichoid infections because of its ease, cost-effectiveness, and simplicity
