Question

BlackTom AI · Accepted Answer

The question asks about the diagnostic term Pell/agra and what it refers to, noting it is caused by lack of niacin or niacinamide in the diet.
Option 1: 'skin/rough' — This aligns with the classic dermatologic manifestation of pellagra, which involves rough, scaly, and pigmented dermatitis on sun-exposed areas. It captures the skin-related aspect of the deficiency.
Option 2: 'skin sores or ulcers' — While pellagra includes skin changes, the typical description emphasizes dermatitis rather than open sores or ulcers. This option overstates ulceration and is not the standard descriptor for pellagra-related skin changes.
Option 3: 'bad skin' — This is a vague, colloquial phrase that lacks medical precision. It does not convey the specific dermatologic features (e.g., dermatitis with hyperpigmentation, scaling) associated with niacin deficiency.
Option 4: 'skin pain' — Pain is not the primary or defining characteristic of pellagra’s rash. The dermatitis is usually described by appearance (rough, scaly, pigmented) and distribution rather than pain.
Overall, the options present varying degrees of specificity about dermatologic symptoms. Among them, the phrasing 'skin/rough' most closely matches the dermatologic description linked to pellagra and niacin deficiency, while the others are either too vague or describe features not central to the classic presentation.
