Fungous Diseases and Compensable Dermatoses 223 



2. DERMATOPHYTID SECONDARY TO A FUNGOUS FOCUS 



The criteria tor the diagnosis of dermatophytid are given in another part 

 of the 1 hook. This diagnosis should never be made from clinical inspection 

 alone. There must be a fungous focus elsewhere, a positive reaction to 

 trichoph) tin and a reasonable certainty of exclusion of all other possible 

 cutaneous disorders, particularly dermatitis venenata. 



3. NONMYCOTIC DISEASE 



There are numerous types of rash which may appear on the hands. A 

 negative reaction to the intracutaneous trichophytin test will exclude 

 dermatophytid. It is beyond the province of this work to discuss further 

 the differential diagnosis of eczematous eruptions of the hand, such as 

 dermatitis venenata, pompholyx, acrodermatitis and pustular psoriasis (see 

 the section on differential diagnosis of dermatophvtosis, Chapter IX, pp. 

 120 ff.). 



4. THE RARE MYCOSES 



Such infections as sporotrichosis may be of occupational origin. Pul- 

 monary moniliasis and aspergillosis in grain handlers have been reported. 



Lane classified fungous diseases of employees who are examined for 

 industrial disability as follows: 



(a) Primary mycotic infection due to poor working conditions or con- 

 tact with an infected fellow worker. 



(b) Exacerbation of a previous mycotic infection due to working con- 

 ditions. 



(c) Fungous infection superimposed on industrial dermatitis. 



(d) Industrial dermatitis following fungous infection. 



(e) Mycotic infection bearing no relation to occupation.
