Scleroderma is a term used to describe diseases that involve hardening and tightening of the skin and the underlying subcutaneous connective tissue. It could be localized to skin and subcutaneous tissue, or may involve the internal organs too in systemic sclerosis. There are disorders that can cause hardening and tightening of skin and mimic scleroderma but are rarely associated with Raynaud phenomenon, sclerodactyly, and autoantibodies in the serum, features specific to scleroderma/systemic sclerosis. These are termed as “scleroderma variants” or “scleroderma like disorders”. The review will discuss the various “scleroderma variants” e.g scleromyxedema, scleredema, nephrogenic systemic fibrosis, and eosinophilic fasciitis.
Key words: Scleroderma-like disorders, scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis.
