Abstract
Malignant melanoma, a rare skin cancer in children, primarily affects individuals over 10 years old. Giant congenital nevi, found in about 1% of newborns, increases the risk. However, the development of melanoma from a pre-existing giant congenital nevus diagnosed during the neonatal period is exceptionally rare. We present a case of congenital melanoma in a newborn, where nodules grew on an existing nevus on the baby's back. Literature on managing such cases was reviewed. This case highlights the importance of considering malignant transformation in congenital nevi and the challenges in their management. Due to limited reported cases over 80 years, conclusive findings on survival and treatment options are difficult to provide. Clinicians should report outcomes to develop a management algorithm for neonatal melanoma. Further studies are needed to enhance understanding of causes and treatment for patients with congenital giant hairy nevi and associated melanoma.

Abstract
The current evidence on paediatric melanoma is heterogeneous, especially regarding the prognosis of different histological subtypes. We sought to systematically review the evidence on paediatric melanoma, highlighting the major sources of heterogeneity and focusing on available data on single patients. A systematic search was performed from 1948 to 25 January 2021. Only studies reporting at least one case of cutaneous melanoma in patients aged ≤18 years were included. Unknown primary and uncertain malignant melanomas were excluded. Three couples of authors independently performed title/abstract screening and two different authors reviewed all the relevant full texts. The selected articles were manually cross-checked for overlapping data for qualitative synthesis. Subsequently data on single patients were extracted to perform a patient-level meta-analysis. PROSPERO registration number: CRD42021233248. The main outcomes were melanoma-specific survival (MSS) and progression-free survival (PFS) outcomes. Separate analyses were done of cases with complete information on histologic subtype, focusing on superficial spreading (SSM), nodular (NM) and spitzoid melanomas, as well as of those classified as de-novo (DNM) and acquired or congenital nevus-associated melanomas (NAM). The qualitative synthesis covered 266 studies; however, data on single patients were available from 213 studies including 1002 patients. Among histologic subtypes, NM had a lower MSS than both SSM and spitzoid melanoma, and a lower PFS than SSM. Spitzoid melanoma had a significantly higher progression risk than SSM and trended toward lower mortality. Focusing on nevus-associated status, DNM demonstrated better MSS after progression than congenital NAM, and no differences were highlighted in PFS. Our findings describe the existence of different biological patterns in paediatric melanoma. Specifically, spitzoid melanomas demonstrated intermediate behaviour between SSM and NM and showed a high risk of nodal progression but low mortality. This raises the question of whether spitzoid lesions are being over-diagnosed as melanoma in childhood.

Abstract
Congenital melanocytic nevus syndrome (CMNS) is a rare condition characterized by pigmented skin lesions that are usually present at birth and are associated with an increased risk of neurological abnormalities and malignant melanoma. It mostly results from a post-zygotic NRAS mutation of neural-derived crest cells, leading to uncontrolled cell growth. Because of the increased knowledge of the genetics underlying CMNS, targeted therapy becomes a promising treatment option. We present a case of CMNS in a newborn. Physical examination at birth showed a giant congenital melanocytic nevus, extending from the occipital to the lower lumbar region. A magnetic resonance imaging scan revealed multiple cerebral and cerebellar parenchymal lesions. Genetic analysis of the cutaneous lesions showed the presence of an NRAS Q61R mutation. The patient was treated with dermabrasion to reduce the color intensity of the nevus. However, this was complicated by recurrent wound infections and laborious wound healing. At the age of 1 year, the patient had an age-appropriate psychomotor development, without neurological deficits.

Treatment of giant congenital melanocytic nevi with cultured epithelial autografts: Clinical and histopathological analysis. Regen Ther 2021; 18:1-6.

Abstract
Introduction Curettage and dermabrasion are effective in the treatment of giant congenital melanocytic nevi (GCMN); however, local infection and hypertrophic scar formation are major issues. Thus, we applied cultured epithelial autografts (CEA) on skin defects after curettage or abrasion of GCMN and assessed the postoperative outcomes. Methods Seven nevi lesions of five patients (aged 3 months to 24 years) were treated with CEA after curettage or abrasion with a dermatome or a surgical bar, respectively. We assessed the postoperative outcomes, including CEA take ratio, erosion and/or ulcer formation in the acute phase, hospitalization days, Vancouver scar scale, and color improvement one year after the operation. In addition, a histological evaluation of a skin biopsy was performed over one year after the operation. Results The CEAs took well on the wound, and the wound surface was mostly epithelized by postoperative day 7 in all cases. While hypertrophic scar formation and slight pigmentation were observed in some lesions, the color was improved in all of the treated lesions. Histopathological examination revealed that the regenerated epidermis had stratified keratinocytes with rete ridges, and the dermal layer without nevus cells regenerated above the remaining dermis layer. Conclusions In this study, we found that early epithelialization and regeneration of the dermal layer was achieved after the application of CEA, suggesting that CEA could be an effective option after curettage or abrasion of GCMN. Cultured epithelial autograft (CEA) application is effective in the treatment of giant congenital melanocytic nevi. The grafted CEA takes well on skin defects post curettage and abrasion. CEAs can achieve rapid epithelization. Normal dermal tissue regenerates after CEA application.

Abstract
INTRODUCTION Giant congenital nevi (GCN), defined as abnormal collections of melanocytes with a diameter greater than 20 cm, occur in 1 in 20,000 births. The lifetime risk of malignant transformation in GCN is reported between 5% and 20% and most commonly occurs in the first 3 to 5 years of life. This article reviews the risk factors of malignant transformation and highlights the diagnostic challenges of malignant melanoma in the pediatric population utilizing a clinical report of a patient with GCN. CASE DESCRIPTION A male patient with giant congenital nevus of the scalp with over 20 satellite nevi was evaluated at the authors' institution at 1 week of life. Beginning at 9 months of age, he underwent serial excision of GCN and satellite lesions. Initial pathology showed compound congenital melanocytic nevus. Subsequent pathology on serial excisions demonstrated compound nevus with clonal expansion of pigmented epithelioid melanocytoma (PEM). He then underwent complete excision of GCN. Pathology demonstrated malignant melanoma that was confirmed by consensus review with outside institutions. The patient was diagnosed with stage III metastatic melanoma after further imaging. He was treated with cervical nodal dissection and interferon alpha-2b. At the time of last visit, the patient had no evidence of melanoma. DISCUSSION This case highlights the difficulties of clinical and pathologic diagnosis of malignant melanoma in the setting of GCN. Pathology can vary between biopsy sites and initial biopsies can suggest nonmalignant melanocytic lesions, as demonstrated in this patient's case. Correct histologic evaluation often requires input from a relatively few centers that treat a larger volume of childhood melanoma. Analysis of gene expression profiles aids in accurate diagnosis of PEM, proliferative nodule or melanoma. It is important to differentiate PEM, a low-grade, indolent melanoma, from malignant melanoma as the treatment differs significantly. Review of pathology by expert dermatopathologists from multiple institutions is vital for diagnostic accuracy, and patients with malignant transformation of GCN are best served by multidisciplinary teams.

Abstract
The epidemiological trends of malignant melanoma have been well described in the literature. However, there remains a paucity of population-based studies assessing melanoma epidemiology in our younger patients (20 years of age or less). Other studies indicate that melanoma incidence has risen in pediatric populations over the last several decades and that these tumors may display different clinical characteristics from those arising in adult populations. We conducted a retrospective, population-based analysis of all incident cases of melanoma occurring in young patients aged ≤20 years in Alberta from 1992 to 2011. Information, including patient age, sex, anatomical location, date of diagnosis, histological subtype (if available), level of invasion, and date of death (if applicable), was obtained from the Alberta Cancer Registry. All cases occurring during a 10-year period from 1993 to 2011 have been reviewed. A total of 71 cases were diagnosed during this time (63% female and 37% male). Age range was 0-20 years (mean of 17.5 years). Truncal melanomas made up 36% of cases, while 28% occurred on the lower limbs, 17% on the upper limbs, and 18% in the head and neck region. Average Breslow thickness was 1.97 mm; 67% of tumors were less than 1 mm thick. Unfortunately, 8 of 71 patients died from their disease. Overall, the incidence of melanoma in patients aged ≤20 years appeared to decrease in Alberta in the past 20 years; however, there has been an increase in the thickness of melanoma at diagnosis, which needs to be addressed.

Abstract
INTRODUCTION Neonatal and infantile malignant melanoma is rare. It may be difficult to diagnose and often carries a poor prognosis. MATERIAL AND METHODS We decided to review the data on congenital, neonatal and infantile malignant melanomas in order to understand their presentation (clinical, histological, molecular), diagnosis, management and outcomes. We performed a literature search of all cases of early-onset melanoma published in PubMed from its inception to March 2019 using the following keywords: "malignant melanoma" OR "melanoma" OR "pigmented nevus" OR "malignant pigmented" AND "infantile" OR "congenital" OR "children" OR "childhood" OR "infancy" OR "neonatal". Congenital melanoma associated with maternal-foetal transmission was not included in the study. RESULTS Sixty-five articles were selected and 85 cases were included in the study. Most patients were male (sex ratio: 1.6). The average age at diagnosis was 5.5 months (minimum-maximum: 0-24 months). The main site reported for congenital melanoma was the head-and-neck area and for neonatal and infantile melanoma the trunk. Half of all patients had a metastatic disease at the time of diagnosis. In metastatic cases, the prognosis was poor with the exception of patients undergoing complete excision of the tumour and metastases. The main treatment for cutaneous melanomas and operable metastasis was surgery, and secondarily, chemotherapy/immunotherapy. CONCLUSION Neonatal and infantile malignant melanoma are rarely reported and not well-documented. It is necessary to collect additional cases to improve our knowledge of this rare disease.

Abstract
AIM The aim of the present study was to investigate the familial and somatic mutations as well as polymorphisms of TP53 gene in patients with uterine leiomyoma. METHODS The study included 35 women with histologically diagnosed as uterine leiomyomas at the Gynecology Department of Adnan Menderes University Faculty of Medicine. Tissue and blood samples were analyzed for mutations and polymorphisms of TP53 gene by next generation sequencing (Miseq-Illumina). Acquired data was compared with the normal data in Ensembl database. Data from 1000 genome project and data from exome sequencing analyses in Intergen Genetic Diagnosis Center (Ankara) were used as controls for polymorphism analyses. RESULTS There were no mutations in tissue and blood samples. However, when the polymorphisms were evaluated, a significant difference was found in NM_000546.5(TP53):c.215C > G (p.Pro72Arg) polymorphism between the study and control groups. The results indicated that P72R/P72R genotype increased the risk of leiomyoma development by 6.3 fold (95% confidence interval [CI]: 2.880-13.793). There was a negative correlation between P72R/WT genotype and leiomyoma development (OR = 0.261, 95% CI: 0.114-0.596). P72R/P72R genotype was statistically higher in the patients with leiomyoma compared with the controls and 1000 genomes from Asian, European and World populations. CONCLUSION The results of the present study suggested that P72R/P72R genotype may be associated with development of uterine leiomyoma in the Turkish population in the Western part of the country.
