A 74-year-old man presented with a congenital naevus of the scalp that has lost its pigmentation over lifetime. Lately, he noticed a newly darkening patch within the grey hair area covering the naevus. The clinical examination revealed a palm-sized area of heavily pigmented hair on a 15x20 cm irregularly pigmented, poorly demarcated brown patch. This article is protected by copyright.

Melanocytic nevi located on specific regions of the body can demonstrate unusual histopathological features such as asymmetry, irregular nesting patterns, pagetoid spread, cytologic atypia, and rarely, mitotic activity. However, despite these features that may raise concern for malignant melanoma, these lesions follow a benign clinical course and do not require intervention. Also known as nevi of special sites or nevi with site-related atypia, these melanocytic nevi were initially described on acral sites and genitalia...

INTRODUCTION: Surgical defect left following excision of a large and neglected scalp melanoma of can pose a significant challenge for the surgeon. Scalp reconstruction encompasses options such as skin flaps, grafts, and various mechanical techniques. In scalp excision that involves dissection beyond the galea, skin grafts and flaps may not take well and not enough tissue may be available for a skin flap. PRESENTATION OF CASE: We present the case of a 64 year-old male with a giant scalp melanoma...

Ultraviolet rays are one of the leading factors in the development of melanoma (MM); however, ultraviolet rays seem not to play a role in non-sun-exposed MM, where systemic immunosuppression, anatomical, and physiological features may contribute toward the development of the malignancy. Our aim was to evaluate vitamin D receptor (VDR) expression in shield-site melanoma (ST-MM) and non-shield-site melanoma (NST-MM) to find features that could explain the different biological behavior of MM according to the area of onset...

Autophagy has been linked with melanoma risk and survival, but no polymorphisms in autophagy-related (ATG) genes have been investigated in relation to melanoma progression. We examined five single-nucleotide polymorphisms (SNPs) in three ATG genes (ATG5; ATG10; and ATG16L) with known or suspected impact on autophagic flux in an international population-based case-control study of melanoma. DNA from 911 melanoma patients was genotyped. An association was identified between (GG) (rs2241880) and earlier stage at diagnosis (OR 0...

CONTEXT: Cutaneous head and neck melanoma is a challenging disease owing to its aggressive nature and often times advanced stage at presentation. Age, sex, and subsite are three prognostic indicators which can be determined prior to treatment or testing, and can allow the practitioner to counsel the patient before initiating therapy. EVIDENCE ACQUISITION: A PubMed search was conducted utilizing various terms relating to the subject matter. Articles over the past 25 years were analyzed and appropriately selected for review...

A 60-year Brazilian woman, presented with an enlarged lymph node in the neck for one year, and a superficial nonulcerated lesion was observed in the scalp. Fine needle aspiration and biopsy of the lymph node revealed amelanocytic metastasis, and immunohistochemistry study showed Melan-A/ Mart-1 antigen (clone A103 and S-100 protein). The entire suspected area of the scalp was further resected and an amelanotic melanoma without angiolymphatic invasion was diagnosed. Ultrasonography and PET-computed tomography showed hypermetabolic cystic area in the right parotid...

Importance: Melanoma in children is rare, accounting for approximately 2% of all pediatric malignant neoplasms. However, for the past 30 years, the incidence of melanoma in those younger than 20 years has been increasing. Location of the primary tumor has been shown to be an important prognostic factor, with melanomas of the scalp and neck conferring a worse prognosis than those originating at other sites. Objective: To examine the survival, demographic, tumor, and treatment characteristics of pediatric head and neck melanoma...

Melanomas can arise either de novo (70%) or from pre-existing melanocytic lesions (30%). Of the latter, most cases arise at the dermoepidermal junction from small congenital or acquired non-blue nevi while only a few arise from blue nevi, notably the cellular subtype and less commonly the common (dendritic) type. Melanomas that arise from blue nevi usually occur on the scalp with greater frequency, as in the case described. Although previous studies have discussed melanoma arising from giant congenital blue nevi, few have discussed those arising from intermediate blue nevi...

We report the case of an 8-year-old child who developed a 9.4-mm-deep melanoma within a medium-sized congenital melanocytic nevus on the scalp. Genetic analysis revealed an activating NRAS Q61R mutation within the melanoma, which is more commonly associated with large or giant congenital melanocytic nevi. This case demonstrates that even a "low-risk" congenital melanocytic nevus at a "low-risk" age must be monitored regularly for the development of malignancy.

Melanocytoma are the melanocytic tumors originating from leptomeningeal melanocytes. Melanocytomas are commonly seen in the central nervous system (CNS) and are often associated with neurocutaneous melanosis (NCM). However, simultaneous presentation of intra-axial and extracranial melanocytoma is a very rare event. Here, we report a unique case of 21-year-old male with intermediate-grade subcutaneous (SC) melanocytoma, mimicking lipoma, occurred synchronously with an intracranial melanocytoma, not associated with NCM...

BACKGROUND: Most studies of cutaneous head and neck melanomas (CHNM) have reported poorer survival in CHNM compared with other sites, especially on the scalp/neck. OBJECTIVE: We sought to compare patient and tumor characteristics between CHNM and cutaneous trunk and extremity melanomas and between CHNM locations (face/ear vs scalp/neck, anterior vs posterior), and to study prognostic factors in patients with CHNM. METHODS: We studied all CHNM (n = 1074) from 8120 cases of cutaneous melanomas diagnosed in Norway in 2008 to 2012...

We examined the association between male-pattern baldness and risk of incident skin cancer, including invasive melanoma, invasive squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) in a prospective analysis, based on 36,032 participants from the Health Professionals' Follow-up Study. In 1992, participants reported their status of male-pattern baldness at age 45 years by choosing from five crown-view pictograms based on Norwood's classification. Diagnosis of skin cancers was reported biennially and information on melanoma and SCC was pathologically confirmed...

Many neoplasms, including lung cancer, breast cancer, melanoma, and gastrointestinal tract malignancy, possess potential for skin metastasis. Skin metastases can represent the first presentation of such malignancies and may be observed incidentally during routine exam. Skin metastases from gastric adenocarcinoma are uncommon, with a prevalence rate of 0.04-0.8%. Cutaneous metastases from gastric cancer are generally observed as the initial symptom of advanced gastric cancer. Early detection and treatment can increase patient survival...

Squamous cell carcinoma (SCC) is the second most common non-melanoma skin cancer and accounts for 90% of head and neck malignancies. Intracranial metastases of SCC are extremely rare. We are reporting a case of 55-year-old female with history of recurrent swelling over right side of forehead which was previously reported as cylindroma. CT scan of head revealed irregular lytic areas in right frontal bone suggestive of erosion. There were multiple small, rim enhancing lesions in bilateral parietal regions. Clinically it was diagnosed as malignant adnexal tumour...

Reconstruction of the scalp following oncologic resection is a challenging undertaking owing to the variable elasticity of the soft tissue overlying the calvarium and the limited amount of tissue available for recruitment. Defect size, location, and skin characteristics heavily influence the reconstructive options available to the surgeon. Reconstruction options for scalp defects range from simple direct closure, to skin grafting, to adjacent tissue transfer with local flaps, and ultimately to free tissue transfer...

Desmoplastic melanoma is an uncommon form of melanoma characterized by atypical spindled melanocytes and abundant collagen deposition. It typically presents in sun-damaged skin of the elderly as an amelanotic, indurated lesion. It has a higher tendency for local recurrence but lower risk of lymph node metastasis vs. conventional malignant melanoma. We report two cases in women aged 59 and 66 who presented with small scalp lesions clinically suggestive of alopecia. The differential diagnosis included alopecia areata, lupus erythematosus and lichen planopilaris...
