List of eponymous diseases

As described above, multiple eponyms can exist for the same disease. In these instances, each is listed individually (except as described below), followed by an in-line parenthetical entry beginning 'aka' ('also known as') that lists all alternative eponyms. This facilitates use of the list for a reader who knows a particular disease only by one of its eponyms, without the necessity of cross-linking entries.

It sometimes happens that an alternative eponym, if listed separately, would immediately alphabetically precede or succeed another epomymous entry for the same disease. There are three conventions that have been applied to these instances:

1. No separate entry appears for the alternative eponym. It is listed only in the parenthetical 'aka' entry (e.g., Aarskog syndrome appears only as a parenthetical entry to Aarskog–Scott syndrome).

2. If eponymous names subsequent to the first are sequenced differently or the eponym is differentiated by another term (e.g., disease versus syndrome), alphabetical sequence dictates which is the linked version versus which is listed as the alternative (e.g., Abderhalden–Kaufmann–Lignac is the linked entry and Abderhalden–Lignac–Kaufmann is the parenthetical alternative entry).

3. If the number of names included in two or more eponyms varies, the linked entry is the one which includes the most individual surnames (e.g., Alpers–Huttenlocher syndrome is the linked entry for the disease also known as Alpers disease or Alpers syndrome).
