Angiotensin-converting enzyme gene insertion/deletion polymorphism and susceptibility to psoriasis: a systematic review and meta-analysis.

BACKGROUND: Psoriasis is a multifactorial disorder, impacted by both genetic and environmental factors. Herein, a meta-analysis assessed the association of angiotensin-converting enzyme gene insertion/deletion (ACE I/D) polymorphism and psoriasis susceptibility. METHODS: A systematic search was used in databases of PubMed/Medline, Scopus, Web of Science, and Cochrane Library up to January 2019 without language restriction. A dichotomous analysis was carried out by RevMan 5.3 using crude odds ratio (OR) and 95% confidence interval (CI) to investigate the association between ACE I/D polymorphisms and the risk of psoriasis. A funnel plot analysis was used by CMA 2.0 to estimate a significant existence of publication bias. RESULTS: Out of 61 studies retrieved from the databases, 16 studies were included in the meta-analysis. The pooled ORs for models of D vs. I, DD vs. II, ID vs. II, ID + DD vs. II, and DD vs. II + ID genotypes were 0.96 [95%CI: 0.82, 1.12; P = 0.58], 0.99 [95%CI, 0.73, 1.36; P = 0.96], 0.81 [95%CI, 0.72, 0.91; p: 0.0003], 0.91 [95%CI, 0.73, 1.13; P = 0.40], and 1.05 [95%CI, 0.85, 1.30; P = 0.68], respectively. A significant difference between ACE polymorphisms in patients with/without family history for the disease [OR = 1.44; 95%CI: 1.24, 1.67; P < 0.001] and also in patients mild/severe psoriasis [OR = 0.70; 95%CI: 0.55, 0.88; P = 0.002] was identified. CONCLUSION: The results of the meta-analysis showed that ACE I/D polymorphism may be associated with psoriasis susceptibility, while ID genotype seemed to have a protective role in Caucasian patients affected by psoriatic arthritis and in studies with hospital-based controls.

Evaluation of the Salivary Level of Cortisol in Patients with Oral Lichen Planus: A Meta-Analysis.

Background and objective: Cortisol, as the main human glucocorticoid, is considered to be a biological marker of stress and anxiety. Since it is known that oral lichen planus (OLP) can appear and worsen during stressful events, cortisol levels have been previously studied in OLP patients. The present meta-analysis aims to assess the salivary concentration of cortisol in OLP patients compared to healthy controls. Materials and methods: Web of Science, PubMed, Cochrane Library, and Scopus databases were searched up to October 2018. The RevMan 5.3 software was used with the mean difference (MD) and 95% confidence intervals (CIs). The CMA 2.0 Software was used to evaluate the publication bias, sensitivity analysis, and meta-regression as possible sources of heterogeneity. Results: 10 studies were analyzed and a total of 269 OLP patients and 268 controls were included. The pooled MD of the salivary levels of cortisol in OLP patients compared with controls was 4.27 ng/mL (95% CI: 2.33, 6.21; P < 0.0001), thus, the salivary level of cortisol in OLP patients was significantly higher than in controls. In Indian-based population studies, a significant difference in the salivary cortisol levels in OLP patients compared with controls was detected (MD = 5.62 ng/mL; 95% CI: 2.67, 8.56; P = 0.0002). In addition, a significant difference in the salivary cortisol levels in the OLP patients compared with the controls was obtained in studies performed with enzyme-linked immunosorbent assay (ELISA) method (MD = 5.33 ng/mL; 95% CI: 2.72, 7.93; P < 0.0001). Conclusion: We suggest that supportive psychological treatment together with the conventional therapy could increase patients' capability to prevent stress, anxiety, and depression.

Evaluation of serum lipid, lipoprotein, and apolipoprotein levels in psoriatic patients: a systematic review and meta-analysis of case-control studies.

INTRODUCTION: Psoriasis is a T cell-mediated inflammatory skin disease in which fatty acids may be a link between psoriasis and its comorbidity. AIM: The present meta-analysis aimed to evaluate lipid, lipoprotein, and apolipoprotein levels in the psoriatic patients compared with the control subjects. MATERIAL AND METHODS: Four databases, including Web of Science, Scopus, PubMed, and Cochrane Library were searched until July 2017. All records analysed were case-control studies. The quality of the questionnaires was evaluated using the Newcastle-Ottawa Scale (NOS). A random-effects meta-analysis was done by Rev Man 5.3 using mean difference (MD) and 95% confidence intervals (CIs). RESULTS: Out of 580 studies identified in four databases, 49 studies were included and analysed in this meta-analysis. The results showed that MD of total cholesterol, triglyceride, LDL, VLDL, HDL, Lp(a), Apo A1, and Apo B levels in the patients compared with the controls were (MD = 13.74 mg/dl; 95% CI: 7.72-19.75; p< 0.00001), (MD = 26.04 mg/dl; 95% CI: 20.77-31.31; p< 0.00001), (MD = 11.41 mg/dl; 95% CI: 6.26-16.57; p< 0.0001), (MD = 4.82 mg/dl; 95% CI: 3.63-6.00; p< 0.00001), (MD = -2.78 mg/dl; 95% CI: -4.53 - -1.03; p< 0.002), (MD = 8.51 mg/dl; 95% CI: 4.86-12.17; p< 0.0001), (MD = -6.60 mg/dl; 95% CI: -13.96 - 0.75; p< 0.08), and (MD = 9.70 mg/dl; 95% CI: 3.02-16.39; p< 0.004), respectively. CONCLUSIONS: This meta-analysis identified abnormality of serum lipid, lipoprotein, and apolipoproteinprofiles in psoriatic patients compared with the controls as well as possibly a greater risk of atherosclerosis and cardiovascular (CV) accidents in the patients.

Effect of diabetes mellitus type 2 on salivary glucose, immunoglobulin A, total protein, and amylase levels in adults: A systematic review and meta-analysis of case-control studies.

BACKGROUND: Saliva is a fluid with the complex compound which can be used as diagnostic markers for type 2 diabetes (T2D). This meta-analysis evaluated salivary glucose, immunoglobulin A (IgA), total protein, and amylase levels in adult T2D compared with the controls as well as the correlation of salivary glucose levels with serum glucose and hemoglobin A1C (HbA1c) levels in both groups. MATERIALS AND METHODS: Web of Science, Scopus, PubMed, and Cochrane Library databases were searched up to July 2017. A random-effects analysis was performed using the mean difference (MD) and 95% confidence intervals. The search terms were "T2D, IgA, amylase, total protein, or glucose" combination with "saliva." The studied variables were the sample size, the percentage of male, the mean age, the condition of saliva sampling, and the salivary levels of mentioned factors. RESULTS: A total of 25 studies were included in this meta-analysis with 1432 and 900 diabetic patients and healthy controls, respectively. MD of salivary glucose level in patients with T2D, compared with the healthy controls, in fasting and nonfasting conditions were 6.23 mg/dL (P = 0.0002) and 6.70 mg/dL (P < 0.00001), respectively. Furthermore, the fasting salivary total protein in the patients was significantly higher than the controls (MD = 167.96 mg/dL; P = 0.03). Non-fasting salivary amylase and secretory IgA levels were significantly lower in the patients (MD = -48.61 IU/mL; P < 0.00001) than in the controls (MD = -9.42 IU/mL; P = 0.0006), respectively. The pooled estimate showed a significant correlation between salivary and serum glucose in the patients (r = 0.765; P < 0.001) and the controls (r = 0.646; P < 0.001) and between salivary glucose and serum glycated hemoglobin in the patients (r = 0.721; P < 0.001). CONCLUSION: Measurement of these salivary factors can be helpful for diagnostic and monitoring purposes of T2D. In addition, salivary glucose as a diagnostic tool can evaluate serum glucose and HbA1c levels in the diabetic patients.

[Human papilloma virus infection in basal cell carcinoma of the skin: a systematic review and meta-analysis study].

Human papillomaviruses (HPVs) are a large and ubiquitous group of viruses that some of them have been suggested as a co-factor in the development of non-melanoma skin cancers. The aim of this meta-analysis study was to evaluate HPVs' prevalence in basal cell carcinoma (BCC) of the skin and the risk of them in the BCC patients compared with the healthy controls. Five databases were searched from January 1980 to February 2017. A random-effects meta-analysis was done with the event rate (ER) for the prevalence of HPVs and odds ratio (OR) for estimation of the incidence of HPVs. Out of 1087 studies, 45 studies were included in the review. The pooled analysis demonstrated that the incidence of γ-HPV was effective in the BCC patients compared with the healthy controls [OR = 1.97; 95% CI: 1.52-2.55; p < 0.00001], but not for α-HPV, ß-HPV and epidermodysplasia verruciformis (EV)-HPV (p > 0.05). The pooled ER of incidence of ß1-HPV in the BCC patients was z3.3% and for ß2-HPV in BCC patients was 44.2%. In conclusion, this meta-analysis showed that probably the risk of γ-HPV was more on BCC patients and also the rate of γ-HPV was higher than α-, ß- and EV-HPVs in the BCC patients.

Efficacy of palifermin on oral mucositis and acute GVHD after hematopoietic stem cell transplantation (HSCT) in hematology malignancy patients: a meta-analysis of trials.

AIM OF THE STUDY: Herein, this meta-analysis study evaluated the efficacy of palifermin after HSCT on the incidence and severity of OM or aGVHD in hematologic malignancy patients in randomized clinical trials (RCTs). MATERIALS AND METHODS: To compare the efficacy of palifermin on adverse events, OM and aGVHD compared with placebo, we searched databases of PubMed/Medline, Web of Science and Cochrane Library for RCTs based on a number of criteria. RESULTS: There was no difference observed in the incidence of OM and aGVHD between two groups. The subgroup analysis didn't show significant differences in two groups for aGVHD grade 2-4 (odds ratio [OR] = 1.54, 95% confidence interval (CI): 0.70-3.39, p = 0.28), aGVHD grade 3-4 (OR = 0.97, 95% CI: 0.48-1.94, p = 0.92), OM grade 2-4 (OR = 0.76, 95% CI: 0.42-1.38, p = 0.37) and OM grade 3-4 (OR = 0.54, 95% CI: 0.25-1.15, p = 0.11], but erythema as an adverse effect in palifermin group was higher than placebo group (OR = 1.86, 95% CI: 1.10-3.15, p = 0.02]. CONCLUSIONS: This meta-analysis of six clinical trials found no statistically significant difference in OM and aGVHD grades in patients receiving 60 µg/kg/day dose of palifermin compared with those receiving a placebo. However, oral mucosal erythema was more prevalent among patients receiving palifermin than patients receiving a placebo.

Treatment of scleredema adultorum of Buschke with intravenous immunoglobulin and mycophenolate mofetil in a 14-year-old girl: a case report.

BACKGROUND: Scleredema adultorum of Buschke is a rare disease characterized by firm and non-pitting edema of the skin. The condition is rare with unknown etiology. Diagnosis is made on the basis of clinical findings and skin biopsy. CASE PRESENTATION: Here, we describe a 14-year-old Iranian girl presenting with non-pitting edema and woody thickening of the skin that progressed within a month. She was evaluated for possible underlying malignancy or connective tissue disorders, which were excluded by multiple laboratory workups. She underwent a skin biopsy which confirmed the diagnosis of scleredema, and she was successfully treated with intravenous immunoglobulin and mycophenolate mofetil. CONCLUSION: While scleredema adultorum of Buschke is a rare disease with no definite treatment, our effort through this report was to highlight the possible benefits of treatment by intravenous immunoglobulin and mycophenolate mofetil.

C.P titanium/Ti-6Al-4V joint by spark plasma welding: Microstructure and mechanical properties.

The welding ability of Ti-6Al-4V alloy is weak due to their two-phase microstructure. On the other hand, friction welding methods lead to significant microstructural changes. In this research, for the first time, pure titanium was successfully joined to the Ti-6Al-4V alloy, without any change in the microstructure and mechanical properties of both alloys, by applying the SPW method. Further, the effects of temperature, pressure, and time of the SPW process on the microstructure and mechanical properties of commercial pure (C.P) titanium joined to the Ti-6Al-4V alloy were investigated. The results indicated that the effect of temperature and pressure on the SPW process was greater than that of time. Further, mechanical properties investigations showed that the yield strength of the joint interface was larger than that of the substrate metal, following which necking and fracture occurred in the pure titanium substrate metal. The alloy (Ti-Ti64) bonded at 800 °C, with a time of 10 min and pressure of 20 MPa, exhibited the superior bonding of 7-9 µm interface thickness, and excellent tensile strength (534 ± 13 MPa) and Vickers micro-hardness (190 ± 5 HV0.1). Investigation of the effect of pressure (normal stress) also showed that with an increase in pressure, because of the reduction of the chemical potential of diffusing species, the joint temperature would drop, and the joint could be created at a temperature below 800 °C.

Seborrheic keratosis in an adolescent: A rare presentation.

Seborrheic keratosis is a common benign epidermal lesion that typically occurs in the elderly population. Its occurrence in childhood and adolescence is rare and can pose a diagnostic challenge for clinicians and dermatopathologists. We report a case of a 16-year-old boy with multiple brown, black oval-shaped stuck-on lesions on his face, which were diagnosed as seborrheic keratosis based on histological findings. The patient had no significant medical history or family history of seborrheic keratosis. In this report, we discuss the differential diagnoses of seborrheic keratosis-like lesions in childhood and adolescence and explain why they were not compatible with our case. We also review the available treatment options. Our case emphasizes the need for dermatologists to consider seborrheic keratosis in the differential diagnosis of cutaneous lesions in young patients.

Malignant proliferating trichilemmal tumor in abdominal wall: Report of a rare case at an uncommon site with literature review.

The proliferating trichilemmal tumor (PTT) is a very rare cutaneous neoplasm that rarely is malignant. PTTs mainly occur in the scalp of elderly women. Only 10% occur in places other than scalp. We present a 62-year-old male patient with malignant PTT in his abdominal wall.

Delayed diagnosis of intraplacental choriocarcinoma in a term healthy neonate-A case report and literature review.

Gestational choriocarcinoma is rare. The intraplacental formation of choriocarcinoma is much rarer. We present a diagnosis of choriocarcinoma, 4 months postpartum, in a 28-year-old, presenting with vaginal bleeding. Three weeks after the last chemotherapy session, the patient's ß-HCG titer was normal and did not require hysterectomy.

Report of two cases of myxoinflammatory fibroblastic sarcomas with preceding hematolymphoid neoplasms: Is there any association?

Myxoinflammatory fibroblastic sarcoma (MIFS) is an uncommon soft tissue sarcoma. We present two cases of MIFS: A known case of Hodgkin's lymphoma presented with hand mass; a recurrence of MIFS with a history of chronic lymphocytic leukemia.

Comparison of Immunohistochemical Methods (IHC) and Fluorescent in Situ Hybridization (FISH) in the Detection of HER 2 /Neu Gene in Kurdish Patients with Breast Cancer in Western Iran.

Background: Amplification of HER2 is an important factor in the diagnosis and treatment of breast cancer. Fluorescence in situ hybridization (FISH) is the gold standard for the detection of HER2-positive tumors. However, the Immunohistochemistry (IHC) assay for the detection of HER2 is more popular in the preclinical laboratory since it is faster and more economical compared to the FISH test. Materials and Methods: In this study, the status of HER2 amplification is determined by the FISH test using 44 formalin-fixed paraffin-embedded tissue samples and comparing the results with the IHC test to determine the reliability of the IHC test. Also, the relationship between HER2 amplification and estrogen, progesterone receptors, P53, age, menopausal status, family history of breast cancer, tumor size, and histological grade were determined. Results: Examination of HER2 in 44 samples by IHC showed 3 (6.8%) and 5 (11.4%) samples were positive (IHC 3+) and negative (IHC 0, 1+), respectively, and 36 (81.8%) samples were ambiguous (IHC 2 +), but examination by FISH showed 21 samples (47, 7%) were positive and 23 samples (52, 3%) were negative. There was a significant difference between IHC and FISH in the detection of HER2 amplification (P=0.019). Also, there was a significant difference between HER2 amplification and menopause in patients (P=0.035). Conclusion: This result demonstrated that the IHC test is not a reliable test to determine HER2 amplification. This study represented that FISH analysis is more reliable than IHC and must be preferentially performed for all cases, especially for HER2 +2 cases for whom the IHC result is 2+.

A Systematic Review and Meta-Analysis: Evaluation of the ß-Human Papillomavirus in Immunosuppressed Individuals with Cutaneous Squamous Cell Carcinoma.

BACKGROUND: Some types of beta-human papillomavirus (ß-HPV) may be one of the probable causes of squamous cell carcinoma (SCC) in transplant recipients. ß-HPVs are linked to SCC in the literature with small number of subjects. AIM: Herein, the first meta-analysis was carried out on the association between ß-HPVs and cutaneous SCC in immunosuppressed patients. METHODS: A systematic search was carried out in the PubMed and Scopus databases up to December 2018. The odds ratio (OR) were calculated by RevMan 5.3 software and the event rate (ER) by Comprehensive Meta-Analysis 2.0 software with a 95% confidence interval (CI). RESULTS: A total of 1250 records were identified through the two databases, but at last eleven studies were included in the meta-analysis that they were published from 1989 to 2018. The results showed a significantly high prevalence of ß-HPVs in cutaneous SCC patients (ER = 69.1%; 95%CI: 58.7%, 77.8%). In addition, the prevalence of overall ß-HPVs and ß-HPVs of 5, 8, 9, 17, 49, 75, and 76 in immunosuppressed cutaneous SCC patients was significantly higher compared with controls. CONCLUSIONS: The findings of the present meta-analysis support the hypothesis that ß-HPV may play a role in cutaneous SCC development in immunosuppressed individuals.

Endoplasmic reticulum aminopeptidase 1 (ERAP1) polymorphisms and psoriasis susceptibility: A systematic review and meta-analysis.

BACKGROUND: Psoriasis has a complex genetic background with a strong heritable component. Herein, the present meta-analysis aims to evaluate the association of ERAP1 polymorphisms with psoriasis susceptibility. METHODS: PubMed, Web of Sciences, Scopus, and Cochrane Library databases were examined with no time limits up to March 2019, without language, age, and sex restrictions. The odds ratio (OR) and 95% confidence interval (CI) were calculated by CMA 2.0 software in a dichotomous analysis using computed effect sizes and having OR and confidence limits for each study. The subgroup analysis based on ethnicity, type of study, and genotyping method was performed. RESULTS: Thirteen articles were involved in the meta-analysis, in details eight were cohort studies and five were case-control studies. The results showed an association between rs27524 [OR = 1.179; 95%CI: 1.081, 1.286; p < 0.001] and rs30187 [OR = 1.237; 95%CI: 1.133, 1.351; p < 0.001] polymorphisms and psoriasis susceptibility; whereas no association was detected with rs26653 [OR = 1.013; 95%CI: 0.798, 1.286; p = 0.914] and rs27044 [OR = 1.164; 95%CI: 0.982, 1.381; p = 0.080] polymorphisms. Psoriasis susceptibility in both Caucasian and Asian ethnicities was related to rs27524 polymorphism, while rs30187 and rs27044 polymorphisms were over-represented in patients belonging to Caucasian ethnicity. In addition, in cohort studies, psoriasis susceptibility was related to rs27524 polymorphism, while the associated polymorphisms were rs26653 and rs27044 in case-control studies, and rs30187 in both cohort and case-control studies. CONCLUSIONS: These findings showed an association between rs27524 and rs30187 polymorphisms and susceptibility to psoriasis, while lack of association was obtained for rs26653 and rs27044 polymorphisms. In order to confirm our results, further studies are needed, also considering different factors, such as type of psoriasis and ethnicity.

An immunohistochemical study of HER2 expression in primary brain tumors.

BACKGROUND: Primary brain tumors (PBTs) include any tumor in the brain whose prognosis is weak because of their histological characteristics. AIM: Herein, this study aimed to assess the HER2 tumor marker frequency in PBTs. MATERIALS AND METHODS: This study was done on the samples of primary brain tumor diagnosis from 2008 to 2015. RESULTS: Out of 107 patients of brain tumor that had a mean age of 40.4 years (61.7% men), the most common location of the tumor was in the supratentorial region (63.85% cases). The prevalence of high-grade astrocytoma (HGA) and low-grade astrocytoma (LGA) at diagnosis was 43.9% and 37.4%, respectively. With regard to HER2 score, HER2-positive (scores 2 & 3) was in 42.1% of patients. On the other hand, HER2-negative (-) was in 57.9%, 2+ in 33.6%, and 3+ in 8.4% of patients. The patients of LGA had significantly younger ages, lower HER2 positivity, and lower HER2 percent compared with the HGA patients. CONCLUSIONS: The type of brain tumors can impact on HER2 expression that high HER2 expression in HGA may be helpful for therapeutic aims. Further studies are required to support these results with a higher volume of patients in the world.

Chromophobe renal cell carcinoma or oncocytoma: a manner of challenge in frozen section diagnosis.

Chromophobe renal cell carcinoma (RCC) is a rare type of kidney neoplasm that is diagnosed in the 6th decade of life with similar incidence in male and female. We reported a case of 73-year-old man with a chief complaint of nocturia, frequency, dribbling and urinary retention with renal mass in ultrasound examination. Histologic examination and immunohistochemistry study revealed the diagnosis of chromophobe RCC which initially was mistaken for oncocytoma in frozen section diagnosis. The pathologist should be aware of this malignant entity and be cautious in diagnosing oncocytoma in frozen section and routine H & E staining.

Pulmonary alveolar microlithiasis and interstitial pneumonitis: a case report of the west of Iran.

Pulmonary alveolar microlithiasis (PAM) is a rare disease with autosomal recessive inheritance. Herein, a 20-year-old lady referred to the hospital with a dry cough for two years. The chest X-ray findings were bilateral reticulonodular opacities in both lungs and honeycomb appearance suspicious for miliary tuberculosis and idiopathic pulmonary fibrosis. A wedge biopsy of lung showed that there were several intraalveolar laminated concretions in the pathology report compatible with pulmonary alveolar microlithiasis and interstitial infiltration of lymphocytes and neutrophils compatible with interstitial pneumonitis. PAM is a rare progressive disease with the production of microliths in pulmonary alveoli. The pathologist, radiologist, and clinician should be familiar with this entity for diagnosis and appropriate management. The family of the patient especially siblings must be evaluated for earlier diagnosis.

Effect of Fixed Orthodontic Treatment on Salivary Nickel and Chromium Levels: A Systematic Review and Meta-Analysis of Observational Studies.

Nickel and chromium ions released from fixed orthodontic appliances may act as allergens. This study aimed to systematically review the effect of fixed orthodontic treatment on salivary levels of these ions by doing a meta-analysis on cross-sectional and cohort studies. The Web of Science, Scopus, Cochrane Library, and PubMed databases were searched for articles on salivary profile of nickel or chromium in patients under fixed orthodontic treatment published from January 1983 to October 2017. A random-effect meta-analysis was done using Review Manager 5.3 to calculate mean difference (MD) and 95% confidence interval (CI), and the quality of questionnaire was evaluated by the Newcastle⁻Ottawa scale. Fourteen studies were included and analyzed in this meta-analysis. Salivary nickel level was higher in periods of 10 min or less (MD = -11.5 µg/L, 95% CI = -16.92 to -6.07; P < 0.0001) and one day (MD = -1.38 µg/L, 95% CI = -1.97 to -0.80; P < 0.00001) after initiation of treatment compared to baseline (before the insertion of appliance). Salivary chromium level was higher in periods of one day (MD = -6.25 µg/L, 95% CI = -12.00 to -0.49; P = 0.03) and one week (MD = -2.07 µg/L, 95% CI = -3.88 to -0.26; P = 0.03) after the initiation of treatment compared to baseline. Corrosion of fixed orthodontic appliances leads to elevated salivary nickel and chromium concentrations early after initiation of orthodontic treatment. Randomized clinical trials controlling for factors affecting the saliva composition are recommended on a higher number of patients and among different ethnicities.

Immunohistochemical expression of P53, Ki-67, and CD34 in psoriasis and psoriasiform dermatitis.

BACKGROUND: Psoriasis is the prime example of psoriasiform tissue pattern and should be differentiated from other psoriasiform dermatoses both clinically and histopathologically. AIM: To evaluate immunohistochemical expression of P53, Ki-67, and CD34 in psoriasis and psoriasiform dermatitis for diagnostic purposes. METHODS: An analytical cross-sectional study was performed on the paraffin blocks of 60 psoriasis and 31 psoriasiform dermatitis patients between 2014 and 2017. The selected formalin-fixed paraffin-embedded tissues from each biopsy specimen were cut into 4-micron sections. Initial sections were stained by hematoxylin and eosin staining. Primary antihuman antibodies against P53, Ki-67, and CD34 were applied. Positive control samples for biomarkers were received from former strongly positive samples of papillary endothelial hyperplasia, high grade lymphoma, and breast ductal carcinoma for CD34, Ki-67, and P53, respectively. RESULTS: Out of 60 psoriasis patients, 56.7% were men, with the mean age of 36.8 years. From 31 psoriasiform patients, 45.2% were men, with the mean age of 37.5 years. Both groups were matched in terms of sex and age. The mean staining of three markers was more significant in psoriasiform dermatitis than psoriasis. CONCLUSION: In spite of some other researches, the present study showed expression of P53, Ki-67, and CD34 biomarkers were significantly higher in psoriasiform dermatitis than psoriasis.
