- Fordyce spots: Not the first physician to have seen the benign anomaly of Fordyce spots, but the first physician so observant
as to recognize this condition as having never been reported and by doing so he gained lasting eponymous credit
- Fordyce lesion: Similarly scrotal angiokeratoma was first described by Cottle in the St. George’s Hospital Reports (1878). Many names were attributed to the condition (mainly described on hands and feet) others described similar lesions using various terms such as naevus à pernions (Bazin 1862), dermatite de congelazione (Breda 1881), verrucous naevi etc. Termed angiokeratoma by Mibelli (1889).
