Ataxia-telangiectasia like disorder (ATLD) is an extremely rare condition, caused by mutation in the hMre11 gene, that could be considered in the differential diagnosis of A-T.
The initialism "CREST" refers to the five main features: calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia.
Sclerodactyly is a component of the CREST variant of scleroderma (CREST is an acronym that stands for calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia.)
As the skin fungal infection has lost some of the characteristic features due to suppression of inflammation, it may have a poorly defined border, skin atrophy, telangiectasia, and florid growth.
