--ANY of the "rheumatic" autoimmune conditions (the ones associated with some version of the Anti-nuclear antibody--a wide range that includes lupus, Sjogren's, Bechet's, polarteritis, Churg-Strauss, scleroderma, etc.) can have effects on the blood vessel tissue and the connective tissue adjoining it that might result in the trophic changes you are describing.

Many of these conditions have predelictions for certain types of tissue damage, but also damage others--Sjogren's goes for moisture producing tissue, for example, but as you've seen it certainly can damage nerves and other tissue. And blood vessels are among the most common "global" targets. So it is certainly possible to have circulatory issues that can be described as "secondary Raynaud's".
