The first case of this unusual condition was reported by Fox and Fordyce in 1902. The eruption was of a papular character, and the lesions were numerous, small, firm, smooth and rounded. The skin was deeply infiltrated and slightly fissured.

The disease involved the axillae chiefly, and in a lesser degree the pubic region was involved. Fox recorded another case of a similar character in this same communication.
