Paradoxical reactions occur when an infection has acute worsening in response to antibiotic therapy. Here, we describe a patient with chronic cutaneous ulcerative lymphangitis that acutely worsened following initiation of antibiotic therapy. The infection was caused by , a species which has not previously been associated with paradoxical reaction in immunocompetent persons. In this case report, we describe our patient's diagnosis and management, review the management of infection, and discuss paradoxical reactions in mycobacterial disease.

Paradoxical reactions (PRs) to biologic medications, such as psoriasis, arthritis, and inflammatory bowel disease (IBD), have been increasingly recognized. The aim of reporting this case is to establish an association between golimumab and exacerbation or new (de novo) IBD in patients with axial spondyloarthritis (SpA). Our case involves a young patient with juvenile-onset ankylosing spondylitis (AS) who developed de novo IBD following golimumab therapy for active spinal disease.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterized by pustules that rapidly progress into ulcers that commonly affect the lower limbs. Recently, successful treatment of PG has been reported with anti-IL 17 treatments. However, there have also been several reports of "paradoxical" induction of new PG lesions after use of IL-17 inhibitors.

Context: This study aimed to investigate the characteristics, diagnosis, and management of tuberculous longitudinally extensive transverse myelitis (TB-LETM), a rare manifestation of tuberculosis.
Findings: We analyzed two rare cases of TB-LETM and discussed their clinical manifestations and imaging findings in the context of the relevant literature. Patient 1, a 23-year-old female, presented with quadriplegia and dysuria, and spinal magnetic resonance imaging (MRI) revealed lesions extending from C1 to T3.

Eczematous paradoxical reactions are commonly associated with anti-interleukin-17A (anti-IL-17A) antibodies. However, IL-23 p19 inhibitors can also cause similar cutaneous manifestations. We present a case of a 77-year-old Japanese woman with palmoplantar pustulosis (PPP), who developed eczematous lesions on her face, neck, and dorsum of the hands 10 weeks after initiating guselkumab treatment.

Rarely, tumor necrosis factor (TNF)-α inhibitors can paradoxically induce eruptions of psoriasis with generalized pustular psoriasis being among the least common presentations. We report a patient who presented with a generalized pustular eruption following adalimumab therapy for hidradenitis suppurativa (HS). The diagnosis of generalized pustular psoriasis was confirmed with a biopsy showing neutrophilic spongiosis and intraepidermal pustulosis.
