- Differential Diagnosis
- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

Type I follicular hyperkeratosis consists of lesions that feel spiky to the touch, consisting of multiple horny dry papules. They are most commonly seen on the backs of the arms. On close inspection they are seen to arise from the hair follicles. This condition is associated with a deficiency of vitamin A and possibly also of riboflavin.
Type II follicular hyperkeratosis is similar in appearance and occurs commonly on the trunk or thighs. The surrounding skin is less dry, and the mouths of the hair follicles are seen to contain brown-pigmented denatured blood. This condition is possibly caused by vitamin C deficiency.
