[Subcutaneous mycotic cysts in Madagascar (Histological aspects. Diagnostic value of the Gomori-Grocott stain. Associations with pheo-sporotrichosis)].

The authors report three cases of mycosic subcutaneous cysts and study the problem of the phaeo-sporotrichosis, a cystic lesion due to dematies brown fungi which are often introduced under the skin by a sting. Because of the absence of brown pigmentation of the fungi present in the three cases reported, the authors propose to group these various cysts under the name of "syndrome of the mycosic cysts" a part of which only being constituted by the phaeosporo trichosis. They emphasize the importance to draw surgeons' attention on such lesions, a priori clinically banal, and pathologists' attention on Gomori-Grocott staining in tropical countries.
