Melanoma in individuals with oculocutaneous albinism has been reported in the literature to be rare compared with the more common occurrence of squamous cell carcinoma and basal cell carcinoma. We present a singular case of amelanotic naevoid melanoma arising from a small congenital naevus in a 16-month old albino boy, the youngest reported to date.

Melanoma is the most deadly form of skin cancer with a yearly global incidence over 232,000 patients. Individuals with fair skin and red hair exhibit the highest risk for developing melanoma, with evidence suggesting the red/blond pigment known as pheomelanin may elevate melanoma risk through both UV radiation-dependent and -independent mechanisms. Although the ability to identify, characterize, and monitor pheomelanin within skin is vital for improving our understanding of the underlying biology of these lesions, no tools exist for real-time, in vivo detection of the pigment...

Randie H Kim, Shane A Meehan
BACKGROUND: Little is known regarding the clinical practice of immunohistochemistry in the diagnosis of melanoma. We aimed to assess the incidence of immunostain usage by referring pathologists and dermatopathologists in melanoma cases sent for consultative review. As a secondary objective, associations between immunostain use and specific melanoma characteristics were also evaluated. METHODS: This is a retrospective review of consultation reports of referred melanomas at a tertiary academic center in New York, New York from 2001-2015...

BACKGROUND: Hypomelanotic or amelanotic melanomas are challenging to identify, especially at mucosal sites. The dermoscopic clues to the diagnosis of mucosal melanomas have been reported to be structureless zones with the presence of blue, gray, or white colors. CASE: A female in her seventies noted a new lesion on the inside of her right labia that first appeared two months prior. Her past medical history was significant for rheumatoid arthritis requiring ongoing treatment with methotrexate for 20 years and adalimumab for 10 years...

We describe the case of a 26-year-old woman with a history of congenital ichthyosiform erythroderma (CIE) who initially presented with a stage IIA amelanotic melanoma on her forearm that was surgically excised. We also review the literature on CIE-associated skin cancers and discuss the possible contribution of ichthyosis to the risk of cutaneous malignancies. Our findings emphasize the importance of close lifelong skin cancer screening in individuals with CIE and highlight the unique malignancy risk of these individuals...

REVIEW
Sang Yub Kim, Sook Jung Yun
Malignant melanoma is a rare disease in Asians but potentially the most aggressive form of skin cancer worldwide. It can occur in any melanocyte-containing anatomic site. Four main cutaneous melanoma subtypes are recognized: lentigo maligna melanoma, superficial spreading melanoma, acral lentiginous melanoma (ALM), and nodular melanoma. Generally, excessive exposure to ultraviolet (UV) radiation increases the risk of melanoma. The exception is ALM, which is the most common melanoma subtype in Asians and is not associated with UV radiation...

Neurotropic melanoma (NM) is a rare variant of cutaneous melanomas. Compared with conventional melanoma, NM is more locally aggressive with an increased tendency for local recurrence but less likely for nodal or distant metastases. The often amelanotic, benign appearance may lead to treatment issues such as late presentation, diagnostic delay, misdiagnosis, insufficient surgical margins, and recurrence with resulting poor outcome. To our knowledge, this is the first case report of NM with contiguous spread to the spinal cord...

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...

BACKGROUND: Solitary pink lesions in differential diagnosis with hypopigmented/amelanotic melanoma present a diagnostic challenge in daily practice and are regularly referred for second expert opinion. Reflectance confocal microscopy (RCM) has been shown to improve diagnostic accuracy of dermoscopically equivocal pink lesions. No studies have been performed to evaluate the effect of adding a second expert reader and automatic removal of lesions with discordant management recommendations and its potential effect on diagnostic sensitivity and final management of these lesions in retrospective or telemedicine settings...

Polypoid malignant melanoma of the oral cavity is extremely rare. This report describes the case of the 3-time occurrence of a polypoid malignant melanoma of the maxillary gingiva in an 84-year-old woman who had removed the primary tumor by herself. The second polypoid malignant melanoma was a black 7-cm pedunculated mass surrounded by pigmented mucosa. Histologically, the tumor exhibited an ulcerated surface lined by squamous cells and contained polygonal cells with brown-and-black pigmentation. The third polypoid malignant melanoma was observed at the same location 7 months after surgery; it was a black hemorrhagic mass approximately 1...

Increased awareness among dermatologists as well as the development of dermoscopy and sequential dermoscopy have contributed significantly toward an increase in the diagnostic accuracy of pigmented melanoma and even of amelanotic melanoma. However, the dermatologist's nightmare is the small group of melanomas that present as common skin diseases, often associated with a significant delay in diagnosis and hence a poor prognosis. The study was carried out to prospectively assess the number of melanomas lacking any clinical suspicion of melanoma and to describe their clinical and histological features over a 6-year observation period in an University Tertiary Skin Cancer Center...

Dear Editor, Apocrine hidradenoma is a rare benign adnexal tumor related to the more common poroma, as they both originate from sweat glands. Hidradenoma usually has an eccrine differentiation, but an apocrine differentiation is possible. Due to its rarity and non-specific clinical appearance it is difficult to differentiate it from other malignant cutaneous lesions. In this challenging task, dermatoscopy could be particularly helpful to better describe, recognize, and differentiate these lesions. Unfortunately, the literature offers only few dermatoscopic descriptions of this rare cutaneous neoplasm...

Melanin is an attractive target for the diagnosis and treatment of malignant melanoma. Previous studies have demonstrated the specific binding ability of benzamide moiety to melanin. In this study, we developed a novel (18)F-labeled NOTA-benzamide conjugate, Al(18)F-NOTA-BZA, which can be synthesized in 30min with a radiochemical yield of 20-35% and a radiochemical purity of >95%. Al(18)F-NOTA-BZA is highly hydrophilic (logP=-1.96) and shows good in vitro stability. Intravenous administration of Al(18)F-NOTA-BZA in two melanoma-bearing mouse models revealed highly specific uptake in B16F0 melanotic melanoma (6...

BACKGROUND: Anorectal malignant melanoma is a rare tumor with a poor prognosis. Typical symptoms (bleeding, pain, perianal mass) are characteristic of hemorrhoids. This, together with the high rate of amelanotic tumors, often delays diagnosis. No therapy guidelines exist. MATERIALS AND METHODS: Based on our own experience of surgically treated patients and an extensive literature search, we present a stage-dependent therapeutic concept. RESULTS: Eight patients (six women) with a mean age of 65 ± 8 years were treated at our institution...

An 8-year-old healthy boy underwent surgery for excision of a painless, enlarging vascularized conjunctival tumor. Histopathology disclosed a mass comprised of interweaving spindle cells and scattered histiocytes in a fibrous matrix, consistent with benign fibrous histiocytoma. This rare tumor can resemble several conditions, including scleritis/episcleritis, inflamed pterygium, juvenile xanthogranuloma, foreign body granuloma, solitary fibrous tumor, amelanotic melanoma, and squamous cell carcinoma.
