[Granulomatous rosacea-like dermatitis under therapy with tofacitinib]. / Granulomatöse rosazeaartiges Exanthem unter Tofacitinib.

ABSTRACT

The case of a 32-year-old female with ulcerative colitis who developed severe papulopustular dermatitis while undergoing treatment with the Janus kinase (JAK) inhibitor tofacitinib. Despite intensive topical therapy, treatment with oral corticosteroids and oral doxycycline was unable to achieve sufficient improvement. Hence, tofacitinib treatment needed to be discontinued. It is well known that the class of JAK inhibitors can cause infectious and allergic cutaneous side effects. However, sterile papulopustular dermatitis as a side-effect has rarely been reported to date.
