RARER NODULAR AND GUMMATOUS AFFECTIONS OF 

 HYPHOMYCETIC ORIGIN. 



Hemispcrosis. | 



Historical and Geographical. — Gougerot and Craven described 

 a case of osteoperiostitis due to Hemispora stellata Vuillemin some 

 years ago. Later Auvray and Bidot found the same fungus in 

 a generalized nodular affection, and De Beurmann, Clair, and 

 Gougerot found it in a gumma situated on the penis of a negro. 



etiology. — The condition is due to a fungus, Hemispora stellata 

 Vuillemin, the description of which is given on p. 1108. 



Histopathology.— The histological lesions resemble those of 

 tuberculosis cutis, as noted by Auvray and Bidot. 



Symptomatology. — Gumma-like swellings are present, either single 

 or multiple. These may later ulcerate. A chronic osteoperiostitis, 

 with thickening of the tibia somewhat resembling the type due 

 to syphilis, has been described. Mercury, however, had no effect. 



Diagnosis. — This is based on isolating the fungus. The fungus 

 microscopically is seldom if ever seen in the lesions, and cultures 

 are necessary. These are carried out in the same manner as for 

 sporotrichosis. 



Treatment. — Potassium iodide given in full doses (gr. xv.-xx.) 

 three times daily is very efficacious. 



Acremoniosis. 



There is only one case on record of this condition by Potron and 

 Noisette in France. The condition is due to a fungus, Acremonium 

 potronii Vuillemin, 1911, which has been described on p. 1121. 

 The patient had fever, which was at first suspected to be typhoid, 

 and several gumma-like swellings developed, which slowly ulcerated. 

 They were not painful. The proximal glands were not enlarged. 



Diagnosis.— This is based on finding the fungus by cultural 

 methods. 



Treatment. — In the only case known an intensive potassium 

 iodide treatment cured the condition. 



|Enantiothamnosis. 



Definition. — A nodular condition due to a fungus, Enantio- 

 thamnus hraulti Pinoy, 191 1. 



Historical and Geographical.^ — This condition has been described 

 by Brault in Northern Africa, who isolated the fungus, the com- 

 plete botanical description of which we owe to Pinoy. 



^Etiology. — ^The causative fungus is E. hraulti Pinoy, 191 1 (see 

 p. 1096). 



Symptomatology. — The condition in the only case so far known 

 was characterized by the presence of nodules on the gluteal regions,
