Which of the following diagnostic criteria is essential for confirming the diagnosis of psoriasis?

A.

Positive skin biopsy showing eosinophils infiltration

B.

Family history of autoimmune diseases

C.

Presence of at least 3 typical psoriasis plaques on the body

D.

Elevated erythrocyte sedimentation rate (ESR) on blood test

Answer and Explanation

The Correct Answer is C

Explanation: The presence of at least 3 typical psoriasis plaques on the body is one of the essential diagnostic criteria for confirming psoriasis. These plaques are characterized by well-defined, erythematous (red), raised lesions with silvery-white scales.

Incorrect choices: a. Positive skin biopsy showing eosinophils infiltration: While a skin biopsy may be performed to support the diagnosis of psoriasis, the presence of eosinophils is not specific to psoriasis and can be found in various skin conditions.

b. Family history of autoimmune diseases: A family history of autoimmune diseases may increase the risk of developing psoriasis, but it is not a definitive diagnostic criterion for the condition.

d. Elevated erythrocyte sedimentation rate (ESR) on blood test: An elevated ESR can indicate inflammation in the body, but it is not specific to psoriasis and may be present in other inflammatory conditions as well.
