    Abstract Prurigo pigmentosa (PP) is a rare skin disorder presenting as erythematous urticarial papules on the chest and leaving reticulated pigmentation. Although the etiology of PP is unknown, conditions associated with ketosis such as diabetes mellitus, ketogenic diet (KD), and anorexia nervosa are implicated. Herein, we report a 21-year-old woman who developed PP after adhering to a KD and responded to resuming a regular diet.

    Abstract Abstract Mycosis fungoides (MF) is the most common type of cutaneous T‐cell lymphoma (CTCL). It may arise rapidly in a scar or keloid, presumably due to a long‐standing proliferative state or autoimmune theory. There should be a low threshold for performing a skin biopsy if unusual lesions develop at those sites.

    Abstract Background and Aim: Consumption of the epidermis (COE) is defined as thinning of the epidermis with attenuation of the basal and suprabasal layers and loss of rete ridges in areas of direct contact with malignant melanocytes. The aim of this study was to investigate the importance of COE as an additional diagnostic criterion for malignant melanoma and to evaluate its relationship to clinicopathological findings. Methodes: The age, gender, localization of the lesion and the histopathological parameters such as tumor type, Breslow thickness, ulceration, and Clark's level were recoeded in 90 malignant melanoma cases. Results: In contrast to other studies, we found that COE was more common in tumors with an acral localization and in the acral lentiginous melanoma.Conclusion: Although COE can be used as a pathological criterion in the diagnosis of malignant melanoma, but no correlation no of COE with ulceration and other prognostic factors were found.

    Abstract Epidermal nevus syndrome is a rare congenital disorder, characterized by epidermal nevi and multiple organ involvement. Multicystic kidney disease has been very rarely reported in this syndrome. Here is the report of a boy presented with multiple epidermal nevi, cardiac anomaly, seizure attack, hemi hypertrophy, and multicystic dysplastic kidney complicated with Wilms' tumor. According to this association, it is suggested to search for dysplastic kidney disease in patients with neurocutaneous disorders.

    Abstract HPVs are DNA viruses include approximately 450 types that are classified into 5 genera (α-, β-, γ-, μ-, and ν-HPV). The γ- and β-HPVs are present in low copy numbers in healthy individuals; however, in patients with an inborn error of immunity, certain species of β-HPVs can cause epidermodysplasia verruciformis (EV), manifesting as recalcitrant cutaneous warts and skin cancer. EV presents as either typical or atypical. Manifestations of typical EV are limited to the skin and are caused by abnormal keratinocyte-intrinsic immunity to β-HPVs due to pathogenic sequence variants in TMC6, TMC8, or CIB1. We applied a transcriptome-based computational pipeline, VirPy, to RNA extracted from normal-appearing skin and wart samples of patients with typical EV to explore the viral and human genetic determinants. In 26 patients, 9 distinct biallelic mutations were detected in TMC6, TMC8, and CIB1, 7 of which are previously unreported to our knowledge. Additionally, 20 different HPV species, including 3 α-HPVs, 16 β-HPVs, and 1 γ-HPV, were detected, 8 of which are reported here for the first time to our knowledge in patients with EV (β-HPV-37, -47, -80, -151, and -159; α-HPV-2 and -57; and γ-HPV-128). This study expands the TMC6, TMC8, and CIB1 sequence variant spectrum and implicates new HPV subtypes in the pathogenesis of typical EV.

    Abstract Smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. This study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better classification and diagnosis. The six year data base of our center was reviewed and 25 patients with cutaneous leiomyoma were included in this study. Of 25 patients, 5 were female and 20 were male. 5 patients had angioleiomyoma (ALM) and 20 had pilar leiomyoma (PLM). ALM had following characteristics: dilated vascular canals intermingled with compact smooth muscle bundles; well circumscribe counter and myxoid and hyaline changes through the tumor. In contrast, PLMs had following histologic features: poor defined outline, entrapped hair follicles and eccrine glands, acanthosis and elongated rete ridges with hyperpigmentation and smooth muscle bundles which are interdigitated with elongated rete ridges. Here we introduced some distinct histological features for each subtype of the cutaneous leiomyoma which can lead to create novel criteria for classification and diagnosis of the lesion.

    Abstract Objective: Melanoma is an aggressive tumor with propensity for early metastasis and poor prognosis with delayed diagnosis. Matrix metalloproteinase-2 (MMP-2) is involved in degradation of extra-cellular matrix proteins and tumor progression. Ki-67 is a predictor of tumor proliferation activity but its prognostic significance in melanoma is controversial. In this study, the prognostic value of MMP-2 and Ki-67 via immuno-staining in head and neck melanoma is investigated. Material and Methods: A retrospective analysis of 24 consecutive primary melanoma samples was performed. All samples were stained with monoclonal MMP-2 and Ki-67 antibodies. Two independent investigators evaluated the stained sections. The reactive cells were considered positive regardless of the staining intensity and reported as percentage. Results: A strong correlation between MMP-2 expression, Breslow tumor thickness, and Clark level of invasion was observed (r = 0.85, P < 0.0001 and r = 0.84, P < 0.0001, respectively). A significant positive correlation was observed between MMP-2 expression and number of lymph node involved (r = 0.55, P value 0.005). MMP-2 over expression (>50%) was an independent predictor of lymph node involvement (OR: 2.1, P value: 0.01). No significant association was observed between Ki-67 expression and Breslow tumor thickness, Clark level, or lymph node involvement. Conclusion: MMP-2 expression correlates with tumor thickness in melanoma and is an independent predictive factor for lymph node involvement.

    Abstract Nodular colloid degeneration (NCD) is a rare dermatological disorder and uncommon type of colloid milium. The degeneration may be related to sun exposure. In this report, three cases, all presenting as multiple plaques and nodules over the nose and the face are depicted. Histologically, these nodular masses were homogeneous, with eosinophilic-cleaved materials expanding the papillary dermis and extending into the deep dermis. Periodic acid Schiff (PAS), crystal violet, and methyl-violet stains highlight the colloid material. All the three cases were finally diagnosed as NCD. NCD could be considered in any case with facial nodules and a long history of sun exposure. We suggest the long-term sun exposure as an etiologic factor; thus sun protection would be the most preventive and available treatment.
