A case of eruptive vellus hair cysts (EVHC) is reported in a patient having paoriasis. The patient, 30-year-old man, has the hyperpigmented umbilicated papules with psoriatic plaques. The histopathologic findings confirm the diagnosis of EVHC, Some lesions of EVHC regressed spontaneously after one month. This is, to my knowledge, the first report of EVHC associated with psoriasis in the Korean literature.

Scabies may be seen in psoriatic patients, although not frequent. This situation provokes many problems including the difficulty of diagnosis and uncertainty of appropriate therapy. We report a case of a young female with an existing psoriasis aggravated following scabetic infestation. At first, she took an antiscabetic treatment but the severity of psoriasis persisted. Subsequently, cyclosporine treatment was started and the psoriatic lesions improved deamatically.

Psoriasis vulgaris, a disorder of partially genetic origin, affects 1-3% of the general population. Vitiligo, generally considered an autoimmune disease, affects 0.5% of the general population. Despite the relatively common occurrence of each disease, the concurrence of each disease in a patient has been considered unusual. It is difficult to discern any particular relationship between vitiligo and psoriasis. Assuming that vitiligo and psoriasis are pathogenetically distinct and are grouped independently of each other. We report a case of psoriasis vulgaris associated with vitiligo in a 19-year-old man. Diagnosis was confirmed by clinical and histopathological findings. He is being treated with narrow band UVB phototherapy.

Pemphigua foliaceus is a rare, relatively mild and chronic variety of pemphigus which is characterized by superficial flaccid bullae which show acantholytic changes in the upper part of the epidermis histopathologically. We report herein five cases of pemphigus foliaceus. The patients had erythematous and crusted patches chiefly on face, chest and back areas, except for case 2 who had flaccid bullae on the upper extrimities. The diagnosis of all these patients were confirmed by immunofluorescence studies. Among these five patients, one was recognized as a rifampicin induced pemphigus foliaceus, and the other one revealed concurrent lesions of psoriasis.

Background: Psoriasis vulgaris is a chronic immune-mediated inflammatory multi-system disease characterised by keratinocyte hyperproliferation. Data regarding patients’ disease severity, knowledge and quality of life (QOL) is important to optimize treatment strategies for psoriasis. This study aims to evaluate and investigate the relationship between disease severity, knowledge and QOL of patients with psoriasis. Methods: A cross-sectional multicentre study utilizing a socio-demographic data collection form, Psoriasis Knowledge Assessment Questionnaire (PKAQ), Dermatology Life Quality Index (DLQI) and Psoriasis Area and Severity Index (PASI was conducted. Correlations between PKAQ, DLQI and PASI were analysed using Spearman’s test. Results: A total of 114 subjects participated in this study. Majority of them had mild psoriasis (n=73, 64%) based on PASI. The mean score of PKAQ was fourteen out of a total possible score of twenty-five, whereas the DLQI had a non-parametric distribution with a median (interquartile range) of 7 (10). Most subjects (32.5%) stated that psoriasis had a ‘moderate effect’ on their QOL, while only 3.5% said that it had an ‘extremely large effect’ on their QOL. There was a statistically significant correlation between PASI and DLQI (rs = 0.264, p = 0.004), with higher PASI scores corresponding to higher DLQI scores. No statistically significant correlation was found between DLQI and PKAQ (rs = -0.048, p= 0.612), and between PASI and PKAQ (rs = 0.058, p= 0.542). Conclusion Impairment of QOL was positively associated with severity of psoriasis. However, there was no significant relationship between knowledge and quality of life, as well as between knowledge and psoriasis severity.

BACKGROUND: The differential diagnosis of psoriasis and seborrheic dermatitis can be difficult when both conditions are localized to the scalp without the involvement of other skin sites. OBJECTIVE: We aimed to evaluate the histopathological differences between psoriasis and seborrheic dermatitis on the scalp and identify favorable criteria for their differential diagnosis. METHODS: We evaluated 15 cases of psoriasis and 20 cases of seborrheic dermatitis of the scalp that had been clinicopathologically diagnosed. Skin biopsy sections stained with H&E were examined. Additional immunohistochemistry was performed, including Ki-67, keratin 10, caspase-5, and GLUT-1. RESULTS: On histopathological examination, mounds of parakeratosis with neutrophils, spongiform micropustules of Kogoj, and clubbed and evenly elongated rete ridges were significantly more frequently observed in psoriasis. Follicular plugging, shoulder parakeratosis and prominent lymphocytic exocytosis were significantly more common in seborrheic dermatitis. Moreover, significantly higher mitotic figures were observed in psoriatic lesions than in seborrheic dermatitis. Immunohistochemistry did not show any difference between psoriasis and seborrheic dermatitis. CONCLUSION: Histopathological features favoring psoriasis include mounds of parakeratosis with neutrophils, spongiform micropustules of Kogoj, clubbed and evenly elongated rete ridges, and increased mitotic figures (≥6/high-powered field). Features indicating seborrheic dermatitis are follicular plugging, shoulder parakeratosis and prominent lymphocytic exocytosis. Immunohistochemistry was not helpful in differentiating psoriasis from seborrheic dermatitis.
