Hi and welcome to you and Miss Millie Mayhem,

I have been doing a little research to see what new information has come to fruition over the past couple of years with regards to calcinosis cutis.

What concerns me in Millie' case is that the ACTH test is normal. We had a wonderful flowchart link on interpreting the LDDS test but that link now no longer works so I can't remember where the LDDS results point to (I have always referred to this flowchart as it was just so wonderful and I never imprinted into my mind!).

I found this link for calcinosis cutis http://www.vetbook.org/wiki/dog/inde...lcinosis_cutis. Generally calcinosis cutis points directly to cushings syndrome. There have however been rare cases of calcinosis cutis which have been caused by other factors which Lori pointed out above.

With the management of calcinosis cutis you are on the right track.

I must admit I am a little perplexed with Millie's test results and the calcinosis cutis given that her ACTH is normal. However an ACTH stim may be normal in some cases of ADH .... which is why I wanted a good explanation of the interpretation of the LDDS test (which has disappeared unfortunately).

What other blood tests has Millie had and what were the abnormal values?
