Differential diagnoses include, depending on the phase of the disease, anthrax, atypical mycobacteriosis
, cowpox, pseudocowpox (Milker's nodule), pyoderma, herpetic whitlow, tularemia, keratoacanthoma, fish-tank granuloma, and sporotrichosis [1, 2, 8].
(1) The differential diagnoses for such lesions includes but are not limited to pyoderma gangrenosum, squamous cell carcinoma, basal cell carcinoma, keratoacanthoma, and other chronic cutaneous infections, such as sporotrichosis, nocardiosis, atypical mycobacteriosis
, tularemia, anthrax, or leishmaniasis.

Differential diagnoses include pyoderma, herpetic whitlow, cowpox, pseudocowpox (milker's nodule), cat-scratch disease, anthrax, tularemia, pri-mary inoculation tuberculosis, atypical mycobacteriosis
, syphilitic chancre, sporotrichosis, keratoancanthoma, and pyogenic granuloma (5).
Both typical tuberculosis and atypical mycobacteriosis
have been described as a complication of pneumoconiosis.
