    Abstract Cell adhesion molecule 1 (CADM1) is one of the immunoglobulin super family adhesion molecules, that is proposed to contribute in the pathogenesis of various types of cutaneous T-cell lymphoma, including mycosis fungoides (MF). In this work, we decided to examine the immunohistochemical expression of CADM1 in MF specimens compared to premycotic parapsoriasis, benign inflammatory dermatosis and normal control skin specimens. 125 participants were enrolled (50 MF, 25 parapsoriasis, 25 inflammatory dermatosis, and 25 healthy controls). Patients were selected from the Outpatient Clinic of Dermatology and Venereology Department, Tanta University Hospitals. From all, 4 mm punch skin biopsies were taken and examined for CADM1 immunohistochemical expression. The current study revealed statistically significant upregulation of CADM1 expression in MF specimens in comparison to parapsoriasis, inflammatory dermatosis, and normal control specimens. Additionally, there was statistically significant positive correlation between CADM1 expression and progression of TNMB staging of MF disease. Therefore, it is possible to recommend CADM1 as a beneficial diagnostic immunohistochemical marker for differentiation between early stages of MF and both the premycotic parapsoriasis and benign inflammatory dermatosis. Moreover, it may be of value in early detection of neoplastic transformation of parapsoriasis as well as in assessment of MF progression.

    Abstract In the recent decades, prostaglandins were recommended as a new therapeutic modality of stable vitiligo with promising efficacy. Therefore, we designed the current work to compare the significance of two different subtypes of prostaglandins [prostaglandin E2 (PGE2) versus prostaglandin F2 alpha (PGF2α)], assisted with NB-UVB phototherapy, in treatment of stable vitiligo. This study was conducted on 30 patients with stable non-segmental vitiligo. Three approximately similar vitiliginous areas were chosen in each patient and assigned into 3 groups. Each group treated with intradermal injection of either PGE2 (group I), PGF2α (group II), or saline as placebo (group III) at frequency once/week for 12 weeks. Concomitantly, all groups received NB-UVB phototherapy twice weekly for 3 months. The outcomes of this study discovered that the therapeutic efficacy of intradermal injection of either PGE2 or PGF2α assisted with NB-UVB phototherapy was comparable with non-significant difference between them in spite of being significantly higher than NB-UVB alone. However, there were a significantly earlier onset of repigmentation and higher degree of satisfaction regarding areas treated with PGE2 than those treated with PGF2α. In conclusion, both PGF2α and PGE2 intradermal injection could be considered as quite simple and affordable techniques in the treatment of stable vitiligo with no reported side effects and good patient satisfaction.

    Abstract Background: YKL-40 is a 40 kDa chitinase-like glycoprotein that is predicted to contribute to the pathogenesis of several inflammatory and neoplastic conditions.
    Objectives: To assess YKL-40 immunoexpression in different stages of mycosis fungoides (MF) to find out if YKL-40 is playing a possible role in disease pathophysiology and progression.
    Methods: This work included 50 patients with different stages of MF diagnosed on the basis of clinical, histopathological, and both CD4 and CD8 immunophenotyping, in addition to 25 normal control skin. The Immune Reactive Score (IRS) of YKL-40 expression was determined in all specimens and statistically analyzed.
    Results: YKL-40 expression reported a significant rise in MF lesions compared to control skin. Among MF specimens, the mildest expression was observed in the early patch stage followed by the plaque stage, while the strongest was in tumor stages. Positive correlations were discovered between IRS of YKL-40 expression in MF specimens and patients' age, disease chronicity, clinical staging, and TNMB classification.
    Conclusion: YKL-40 might participate in MF pathophysiology, and the highest expression is associated with advanced stages of the disease and poor outcomes. Therefore, it might be of value as a prognosticator for monitoring high-risk MF patients and follow-up assessment of treatment success.

    Abstract Background: Caveolin-1 (Cav-1) is a significant structural and regulatory constituent of cell membranes that has been implicated in cell kinetics and inflammation.
    Objective: To assess Cav-1 expression in psoriasis before and after phototherapy.
    Patients and methods: Thirty psoriasis cases and 30 healthy controls were recruited. Cases were managed with narrow band-ultraviolet B (NB-UVB) phototherapy at frequency three times per week for 12 weeks. From every case, two biopsy specimens were gained from psoriatic lesions (pre and post phototherapy), in addition to one from apparently normal skin of psoriasis cases. Regarding the control group, one biopsy was taken from a matched site. All were studied for Cav-1 antibody immuno-expression.
    Results: There was a significant decrease in Cav-1 expression in psoriatic lesions compared to both the apparently normal skin of psoriasis patients and standard control skin of healthy individuals. After NB-UVB phototherapy, significant upregulation of Cav-1 immunostaining score was observed in previously psoriatic skin when compared to that before treatment. In addition, there were significant negative correlations between Cav-1 immunostaining score and the clinical scores of psoriasis severity including; the erythema, scaling, and induration (ESI) score and the patient psoriasis area and severity index (PASI) score.
    Conclusion: Induction of Cav-1 expression may be a likely pathway for the effectiveness of NB-UVB in psoriasis. Cav-1 may be a useful marker for evaluation of psoriasis severity, disease progression, and therapeutic efficacy.

    Abstract Regardless of the continuous discovery of innovative modalities for the treatment of vitiligo, none of them ensure excellent therapeutic outcome. Microneedling had been suggested either singly or concomitantly with other therapeutic modalities for vitiligo with encouraging results. Latanoprost, a prostaglandin F2-alpha (PGF2α), and their analogues are recently recommended for vitiligo treatment. This study was designed to assess the therapeutic efficacy of microneedling in combination with NB-UVB phototherapy versus their combination with latanoprost in vitiligo. It was conducted on 50 patients presented with stable bilateral localized nonsegmental vitiligo. In every patient; two bilateral, nearly symmetrical lesions were selected and treated by microneedling (12 sessions at 2-week interval) followed by topical application of latanoprost 0.005% solution on one side, and topical saline (as placebo) on the other side. In addition, all patients received concomitant NB-UVB phototherapy (three sessions/week) for 6 months. Significant clinical improvement of vitiligo lesions with significant increase in the degree of repigmentation were reported in response to both treatment regimens. Latanoprost in combination with microneedling and NB-UVB provides more significant therapeutic outcomes than combined microneedling and NB-UVB. In conclusion, topical latanoprost 0.005% enhances the therapeutic efficacy of combined microneedling and NB-UVB phototherapy in localized stable nonsegmental vitiligo.

    Abstract Keloids characterize a definitely challenging type of cutaneous scars for which a diversity of therapeutic modalities has been suggested. The aim of this work was to compare the therapeutic efficacy of intralesional injection of botulinum toxin type-A (BTX-A), platelet rich plasma (PRP), and triamcinolone acetonide (TAC) in keloids. A total of 60 keloids patients were enrolled and divided randomly into three equal groups. Group I treated by intralesional BTX-A injection, group II treated by intralesional PRP injection, and group III treated by intralesional TAC injection. Clinical assessment was done by Vancouver Scar Scale (VSS), Verbal Rating Scale (VRS), and dermoscopic examination. Additionally, histopathology and immunohistochemistry of connective tissue growth factor (CTGF) expression were evaluated. The results of this study revealed significant improvement of both VSS and VRS in response to all treatment modalities. There was significant improvement of VSS in BTX-A and PRP groups more than TAC group. However, no significant difference observed between BTX-A and PRP groups. Immunohistochemical examination showed significant decrease of CTGF expression after treatment in BTX-A and PRP groups more than TAC group. In conclusion, both BTX-A and PRP could yield a chance for cosmetically better outcomes in keloids treatment than conventional TAC injection.
