Co‐existence of psoriasis and melanoma in a large urban academic centre population: a cross‐sectional retrospective study

Abstract

Our findings show a statistically significant association between psoriasis and melanoma. After adjusting the OR for phototherapy and age, a statistically significant association remained. Further investigations exploring these associations are warranted in order to establish the relative risk for melanoma in psoriasis patients.

Methotrexate treatment and risk for cutaneous malignant melanoma: a retrospective comparative registry-based cohort study

“…18 A retrospective, registry-based, American study showed that there was a statistically significant association between psoriasis and melanoma and the association remained after adjusting the OR for phototherapy and age. 19 An Italian retrospective study compared a group of nondermatology patients consisting of patients needing vascular surgery and patients with psoriasis. The study demonstrated that patients with psoriasis had a significantly lower probability of having melanoma.…”

Association of atopy and tentative diagnosis of skin cancer – results from occupational skin cancer screenings

“…The relationship between atopy and carcinoma of the skin has been examined by several studies, with divergent results. [1][2][3][4][5][6] In the scientific literature, two underlying major concepts are discussed. The first cites allergies as a stimulant of the immune system and protective factor with respect to the development of carcinoma.…”

Coexistence of psoriasis and primary high-grade subcutaneous leiomyosarcoma

“…Studies associate an increased risk of certain cutaneous and lymphoproliferative malignancies with psoriasis. [123]…”

“…[12] The risk is highest for those with severe psoriasis and also for patients treated with PUVA, methotrexate, cyclosporine, topical tar, and biologicals.…”
