Letter: It is Dermatosis neglecta.

Area of Science:

• Dermatology
• Rare Diseases
• Syndromic Conditions

Background:

• A dramatic case of severe retention hyperkeratosis associated with Susac syndrome was reported in 2010.
• The reported condition shares clinical and histopathological characteristics with Dermatosis neglecta, a disorder previously described by Poskitt et al.

Discussion:

• This article posits that the severe retention hyperkeratosis in the Susac syndrome case is, in fact, Dermatosis neglecta.
• The authors emphasize that the histopathology, pathogenesis, and treatment align with Dermatosis neglecta, despite being presented under a different context.

Key Insights:

• Severe retention hyperkeratosis in Susac syndrome may represent Dermatosis neglecta.
• Recognition of this overlap can aid in accurate diagnosis and management.
• The underlying mechanisms of Dermatosis neglecta are relevant to understanding this presentation.

Outlook:

• Further research is warranted to confirm the association between Susac syndrome and Dermatosis neglecta.
• Investigating the specific triggers or predispositions within Susac syndrome leading to Dermatosis neglecta is crucial.
• Standardizing diagnostic criteria and terminology for such presentations will improve clinical practice.
