BackgroundPlasma cell cheilitis is an unusual benign plasma cell proliferative disease of an unknown etiology that typically presents on the lip.ObjectiveThe aim of this study was to investigate the clinicopathological characteristics of 13 cases of plasma cell cheilitis.MethodsThe present study investigated the clinical manifestations, treatment modalities, and outcome of 13 patients diagnosed with plasma cell cheilitis from 2011 to 2016 at Kangdong Sacred Heart Hospital and Hallym University Sacred Heart Hospital. Biopsy specimens of the all cases were evaluated using conventional hematoxylin and eosin staining with kappa and lambda immunoglobulin light chain immunohistochemistry.ResultsThe age of the patients ranged from 39 to 86 years (mean, 64.7 years), with male predominance. Histopathologically, 61.5% and 38.5% of patients showed band-like and pan dermal plasmacytic infiltrates, respectively. Eosinophilic infiltration was noted in 69.2% of patients. All cases showed both kappa and lambda immunoglobulin light chain reactivities, and kappa predominance was confirmed in 9 patients (69.2%). A majority of the patients was treated with local therapy, such as intralesional steroid injection with topical tacrolimus. Among the 13 patients, plasma cell cheilitis completely resolved, partially resolved, and recurred in 3 (23.1%), 5 (38.5%), and 5 patients (38.5%), respectively.ConclusionPlasma cell cheilitis presented as erosive edematous circumscribed patches or plaques affecting mainly the lower lip of elderly male patients. The majority of histopathology cases showed characteristic plasma cell aggregation on the upper dermis that was immunopositive for immunoglobulin light chain, with kappa predominance.

Both LPNY and PDL are effective in treating rosacea-associated nasal telangiectasia. If LPNY is used properly to avoid side effects with careful consideration, it can also be used as a good modality.

BackgroundPsoriasis is associated with increased risk of cardiovascular morbidities, especially in severe cases. Severity of the disease has been known to be associated with higher prevalence of these risk factors. However, in the absence of robust measurements, studies to date relied mostly on treatment spectrum as a proxy for the severity.ObjectiveTo evaluate the relationship between psoriasis area and severity index (PASI) and cardiovascular risk factors in Korean patients.MethodsPresence of diabetes mellitus (DM), hypertension, smoking history was surveyed through questionnaires and serum lipid profile analysis were done after fasting overnight. The severity of psoriasis was assessed using PASI scores: mild, <10; moderate to severe, ≥10. Cardiovascular risk factors such as smoking, hypertension, diabetes and dyslipidemia were compared between the mild group and moderate to severe group. The prevalence of diabetes and hypertension was compared among these two groups of psoriasis patients and the general population based control; age and gender were matched among three groups accordingly prior to analysis.ResultsA total of 256 patients with plaque type psoriasis were included. Between mild group and moderate to severe group, significant differences of cardiovascular risk factors including lipid profile were not discovered except in triglyceride level. Comparing to general population, prevalence of diabetes was found significantly higher in psoriasis patients while that of hypertension was similar.ConclusionOur results suggest that among cardiovascular risks, presence of DM and triglyceride level seem to be associated with the presence of psoriasis in Korean psoriasis patients, while other factors may not contribute meaningfully.

A 4-month-old infant presented with asymptomatic soft nodules on his right forearm, which had developed since birth. On the suspicion of nevus lipomatosus superficialis (NLS), biopsy was performed. Histopathologic findings showed monomorphic polygonal cells with abundant granular cytoplasm. Immunohistochemical stains for CD68 and vimentin were strongly positive, but were negative for S-100 protein. Based on the pathologic findings, the patient was diagnosed as non-neural granular cell tumor (NN-GCT). GCT can be divided into conventional and non-neural GCT by immunoreactivity for S-100 protein. NN-GCT is typically manifested as a well-circumscribed, papulo-nodular dermal mass, and is known to occur in a younger group than does in conventional GCT, but is rare among children. To our knowledge, there have been no case reports of NN-GCT which appeared at birth and presented as grouped nodules. Therefore, we report this interesting case of congenital NN-GCT clinically mimicking NLS.
