Article Abstract
Pyoderma gangrenosum (PG) is a rare, neutrophilic dermatosis that results in progressive, painful ulcers most commonly affecting the lower extremities. Although immunosuppressants are frequently used for therapy, there is no standard treatment approach, and recurrences are common. The pathogenesis of PG is believed to involve dysregulation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway, supporting the potential use of JAK/STAT inhibitors as a treatment option. This case series describes the successful use of upadacitinib, a selective JAK inhibitor, in the management of PG.

Aim: To evaluate the therapeutic efficacy and safety of the Janus kinase (JAK) inhibitor tofacitinib in the management of refractory perianal pyoderma gangrenosum (PG) under conditions of baseline immunosuppression and bone marrow suppression.
Methods: We present a 62-year-old male with a 4-month history of painful, progressive symmetrical perianal ulcerations diagnosed as PG, coexisting with condyloma acuminatum. The patient had a background of pure red cell aplasia and myasthenia gravis, and was undergoing chronic immunosuppressive therapy with prednisolone and tacrolimus.

We report a rare case of a sterile nasal septal abscess (NSA) occurring as an extraintestinal manifestation of ulcerative colitis (UC), accompanied by a novel histopathologic finding. A 40-year-old woman with relapsed UC presented with nasal swelling, purulent discharge, hematochezia, and skin lesions. Computed tomography revealed an anterior NSA, and emergent endoscopic drainage was performed.
