Occupational Dermatoses

Slides 76 to 80

Slide 76 - Herpetic fingers

   
Dentists, physicians and other health personnel may develop herpes simplex on their hands.

Slide 77 - M. marinum

   
This granulomatous infection in an employee of a tropical fish store was due to Mycobacterium marinum, which is usually acquired from an inoculation injury. It is also referred to as swimming pool granuloma.

Slide 78 - Milker's nodule

   
Milker's nodule is due to a viral infection which occurs on the udders of cows and can be transmitted to man. The lesions are nodular rather than vesicular and run a self-limiting course in several months.

Slide 79 - Orf

   
Orf, a viral dermatosis, is acquired from contact with infected sheep. While the hand are most often affected, the virus can be carried to other skin sites.

Slide 80 - Tick bite

   
Ticks present a considerable problem for outdoor workers in wooded areas. Because the initial bite is painless, the first sign may be itching at the site of the bite several days after.
