This study aimed to investigate treatment resistance mechanisms in palmoplantar psoriasis and assess the contribution of IL\u201017, IL\u201023, and IL\u201036\u03b1 to the differential diagnosis of palmoplantar psoriasis and eczema. Immunohistochemical levels of these cytokines were measured in paired acral and non\u2010acral psoriatic samples.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively included 73 patients: 25 with only palmoplantar psoriasis, 25 with palmoplantar eczema, and 23 with both conditions and concurrent plaque psoriasis.

In palmoplantar eczema patients, IL\u201017 and IL\u201023 expression was higher than in palmoplantar psoriasis patients; however, IL\u201036\u03b1 expression was similar in both conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The diminished expression of IL\u201017 and IL\u201036\u03b1 in palmoplantar psoriasis compared to other body sites may contribute to variable responses to targeted treatments.
