- Syndromal ichthyosis
- Leprosy
- Sarcoidosis
Show Solution
The Correct Option is A
Solution and Explanation
Read the skin: diffuse dry, fish-scale (ichthyosiform) scaling all over the body is ichthyosis. The single most common variant by far is ichthyosis vulgaris.
The defect to remember: ichthyosis vulgaris comes from reduced filaggrin in the stratum granulosum, which wrecks the skin barrier and lets moisture escape, producing the dry, scaly look likened to fish or alligator skin.
Sort out the options: syndromal ichthyosis is rarer and carries systemic associations, so it is not the default for plain scaly skin. Leprosy presents with anaesthetic hypopigmented patches and thickened nerves, not generalised scaling. Sarcoidosis makes infiltrated granulomatous plaques. The classic generalised scaling is ichthyosis vulgaris.
