Pedunculated lipofibroma is a rare disorder characterized by ectopic deposits of mature adipose tissue in the dermis. It is a dorne shaped or sessile papule which occurs at any site and develops later in life. We, herein, report two cases of pedunculated lipofibroma which have developed on the chin of a 64-year-old man and the buttock of a 47-year-old woman.

Gastric glomus tumor is an uncommon benign, submucosal neoplasm and does not require radical surgical procedure. Because there are no specific clinical or radiologic features associated with the glomus tumor, it can be recognized only by its histologic characteristics. We report a 30-year-old woman who had 10 years history of epigastric hunger pain. Radiologically, a gastric submucosal tumor was discovered, which was suggestive of leiomyoma. Gastric antrectomy was performed. The tumor cells showed immunohistochemical and ultrastructural evidence of smooth muscle differentiation.

Purpose: To assess the drug retention rate of interleukin-17 inhibitors (IL-17is) over long-term observation in patients with axial spondyloarthritis (axSpA) in whom treatment with tumor necrosis factor inhibitors (TNFis) failed and to determine baseline factors associated with discontinuation of IL-17is. Materials and Methods: This retrospective cohort study included 68 patients with axSpA started on IL-17is after an inadequate response or intolerance to ≥1 TNFis. Drug retention rates at 1, 2, and 3 years were assessed. Baseline (i.e., at initiation of IL-17is) factors associated with discontinuation of IL-17is were evaluated using multivariable Cox proportional hazard regression analysis. Results: Over 1933.9 person-months of observation in 68 patients, discontinuation of IL-17is occurred in 27 (39.7%) patients. Twenty (29.4%) patients discontinued IL-17is because of ineffectiveness, and 7 (10.3%) patients discontinued IL-17is because of adverse events. The 1-year, 2-year, and 3-year drug retention rates for IL-17is were 71.9%, 66.5%, and 62.0%, respectively. Current smoking was associated with a higher risk of IL-17is discontinuation [adjusted hazard ratio (HR)=2.256, 95% confidence interval (CI)=1.053–4.831, p=0.036], while previous use of ≥3 TNFis (vs. 1) was significantly associated with a lower risk of IL-17is discontinuation (adjusted HR=0.223, 95% CI=0.051–0.969, p=0.045). Conclusion In patients with axSpA in whom TNFis failed, the long-term drug retention rate of IL-17is appears to be acceptable, with a 3-year drug retention rate of approximately 60%. Current smoking was associated with a higher risk of discontinuing IL-17is, whereas previous use of ≥3 TNFis was associated with a lower risk of discontinuing IL-17is.

Purpose: To evaluate whether vascular uptake on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18F-FDG PET/CT) during the clinically inactive state of Takayasu arteritis (TAK) is associated with disease relapse. Materials and Methods: Patients with TAK who underwent 18F-FDG PET/CT during the clinically inactive state of the disease between 2006 and 2019 were included. Clinically inactive disease was defined as a status not fulfilling the National Institutes of Health (NIH) criteria for active disease in TAK. Relapse was defined as recurrence of clinically active disease after a clinically inactive period, requiring change in the treatment regimen. Vascular uptake on 18F-FDG PET/CT was assessed using target/background ratio (TBR), calculated as arterial maximum standardized uptake value (SUV)/mean SUV in venous blood pool. Multivariable Cox regression analysis was performed to identify factors associated with relapse. Results: A total of 33 patients with clinically inactive TAK were included. During a median observation period of 4.5 (0.9–8.1) years, relapse occurred in 9 (27.3%) patients at median 1.3 (0.7–6.9) years. Notably, TBR [1.5 (1.3–1.8) vs. 1.3 (1.1–1.4), p=0.044] was significantly higher in patients who relapsed than in those who did not. On multivariable Cox regression analysis, the presence of NIH criterion 2 [adjusted hazard ratio (HR): 7.044 (1.424–34.855), p=0.017] and TBR [adjusted HR: 11.533 (1.053–126.282), p=0.045] were significantly associated with an increased risk of relapse. Conclusion Vascular uptake on 18F-FDG PET/CT and the presence of NIH criterion 2 are associated with future relapse in patients with clinically inactive TAK.

Pigmented fungiform papillae of the tongue is a rare disorder in Korea. It is characterized clinically by pigmentation confined to the fungiform papillae and histopathologically by the presence of melanophages in the upper dermis. We report a case of pigmented fungiform papillae of the tongue in a 21-year-old woman who had brown to violaceous dots on the fungiform papillae and pigmented patches on the right lateral dorsum of the tongue. Histological findings showed increased melanophages in the upper dermis.
