    Abstract Purpose of review: The pathogenesis of systemic sclerosis (SSc) has been linked to dysfunctional B cells as demonstrated in previous research. This review aims to show the evidence and ongoing clinical trials of B cell-targeted therapy and overview the various aspects of B cell involvement in SSc.
    Recent findings: We provide an overview of the current understanding and therapeutic strategies targeting B cells in SSc patients. Several molecular targets of B cells have been identified for treating SSc, including CD20, CD19, B-cell activating factor (BAFF), and proteasome.
    Summary: Many clinical trials have demonstrated that B cells play a critical role in the pathogenesis of SSc and may be a potential therapeutic target to improve disease symptoms. Although large-scale clinical studies are needed, various B cell-targeted therapies have the potential to address the unmet needs of SSc patients.

    Abstract Local skin flap from the surrounding area is often chosen for reconstruction of skin defects in the nasal region, but it is problematic because it creates new facial scar and requires skill of design. On the other hand, full-thickness skin graft is associated with problems such as color mismatch and scar contracture at the recipient site. We reconstructed nasal defects of seven patients using modified dermis graft technique. In this method, de-epithelialized full-thickness skin graft is transplanted and then epithelialized from the surrounding area. This is a simple and easy procedure without causing a new scar on the face and is aesthetically and functionally superior to a standard full-thickness skin graft; therefore, it is a useful method of reconstruction of the nasal area.

    Abstract Systemic sclerosis (SSc) is an autoimmune disease characterized by vasculopathy, aberrant immune activation, and extensive tissue fibrosis of the skin and internal organs. Because of the complicated nature of its pathogenesis, the underlying mechanisms of SSc remain incompletely understood. Angiogenic factor with a G-patch domain and a Forkhead-associated domain 1 (AGGF1) is a critical factor in angiogenesis expressed on vascular endothelial cells, associated with inflammatory and fibrotic responses. To elucidate the possible implication of AGGF1 in SSc pathogenesis, we investigated the association between serum AGGF1 levels and clinical manifestations in SSc patients. We conducted a cross-sectional analysis of AGGF1 levels in sera from 60 SSc patients and 19 healthy controls with enzyme-linked immunosorbent assay. Serum AGGF1 levels in SSc patients were significantly higher than those in healthy individuals. In particular, diffuse cutaneous SSc patients with shorter disease duration had higher levels compared to those with longer disease duration and limited cutaneous SSc patients. Patients with higher serum AGGF1 levels had a higher incidence of digital ulcers, higher modified Rodnan Skin Scores (mRSS), elevated serum Krebs von den Lungen-6 (KL-6) levels, C-reactive protein levels, and right ventricular systolic pressures (RVSP) on the echocardiogram, whereas they had reduced percentage of vital capacity (%VC) and percentage of diffusing capacity of the lungs for carbon monoxide (%DLCO) in pulmonary functional tests. In line, serum AGGF1 levels were significantly correlated with mRSS, serum KL-6 and surfactant protein D levels, RVSP, and %DLCO. These results uncovered notable correlations between serum AGGF1 levels and key cutaneous and vascular involvements in SSc, suggesting potential roles of AGGF1 in SSc pathogenesis.

    Abstract Palmoplantar pustulosis (PPP) is a chronic skin inflammatory disease characterized by sterile pustules on the palms and soles. Pustulotic arthro-osteitis (PAO) is a major comorbidity of PPP, frequently affecting the anterior chest wall. PPP and PAO are thought to be closely associated with focal infection. We report a female in her 40s who developed pustules on her palms and soles with tenderness of both sternoclavicular and left sacroiliac joints, which were not improved with non-steroidal anti-inflammatory drugs. Of note, she showed a great response to amoxicillin, resulting in the almost complete resolution of her skin lesions and arthralgia. We also reviewed previous reports to learn more about the potential therapeutic options of antibiotics for PAO.

    Abstract Stewart-Treves syndrome (STS) is a rare cutaneous lymphangiosarcoma developing from chronic lymph edema as a consequence of radical mastectomy or surgical invasion of the groin for the treatment of cervical or penile cancer. Previous reports suggested possible mechanisms in the development of lymphangiosarcoma that correlate with the immunological background of STS patients. In this report, we described two cases of STS developing in patients who underwent radical dissection for cervical cancer, we employed immunohistochemical staining of IL-23 and IL-17.
