Elizabeth Harris, Adnan Mir
Cowden syndrome (CS) is an autosomal dominant genodermatosis associated with characteristic mucocutaneous findings of facial trichilemmomas, palmoplantar keratoses, sclerotic fibromas, and oral papillomas. Mucocutaneous neuromas have also been reported in association with CS. We describe a patient with CS whose sole cutaneous finding was palisaded encapsulated neuromas (PENs) with a plexiform growth pattern in an acral location. Along with previous reports, this case suggests that acral plexiform PENs may be an early, highly specific finding in CS and highlights the importance of screening these patients for PTEN mutation...

BACKGROUND: Symmetrical acrokeratoderma (SAK) is characterized by brown to black hyperkeratotic patches on acral regions. Although epidermal hyperkeratosis and acanthosis are consistent pathological changes, the nature of epidermal hyperplasia is unknown. AIM: To evaluate epidermal proliferation and differentiation and melanocytic density in skin lesions of SAK. METHODS: Expression of keratin 10 (K10), K14, K16, involucrin, filaggrin, Ki-67, and Melan-A was detected by immunohistochemistry in eight patients with SAK, seven patients with ichthyosis vulgaris (IV) and six healthy controls (HCs)...

BACKGROUND: Acrodermatitis enteropathica (AE) is a rare dermatitis secondary to zinc deficiency most commonly seen as an inherited disease in infants. In the last decade, increased number of reports have been published on the acquired form that presents in adulthood. Unlike its inherited counterpart, acquired AE (AAE) is often secondary to underlying pathologic or iatrogenic etiologies that interfere with nutritional absorption, such as inflammatory bowel disease or alcoholism. Various gastrointestinal pathologies have been associated with AAE, but there is currently no report on its association with adult autoimmune enteropathy (AIE), a rare gastrointestinal disorder commonly seen in infants, with limited cases reported in adults...

Laugier-Hunziker syndrome (LHS) is a rare condition characterized by acquired hyperpigmentation involving the lips, oral mucosa, acral surfaces, nails and perineum. While patients with LHS may manifest pigmentation in all of the aforementioned areas, most present with pigmentation localized to only a few of these anatomical sites. We herein report a patient exhibiting the characteristic pigment distribution pattern associated with LHS. Since LHS is a diagnosis based on exclusion, we discuss the differential diagnosis of mucocutaneous hyperpigmentation...

BACKGROUND: Paraneoplastic acral vascular syndrome (PAVS) is a rare phenomenon which is observed in patients with adenocarcinomas and other malignancies. Various potential pathogenic mechanisms such as tumour invasion of sympathetic nerves, hyperviscosity, hypercoagulability, vasoactive tumour-secreted substances, and immunological mechanisms have been suggested. CASE PRESENTATION: We report a 60-year-old Caucasian male attended our hospital with a bulky lymph node mass in the right axilla...

Collodion baby is a term used to describe a phenotype characterized by the presence of a tight, translucent membrane that covers the entire skin at birth. This membrane usually sheds around 10 to 14 days and reveals the underlying disease (mainly different types of Recessive Ichthyosis or other infrequent disorders). A rare variant of this phenotype is known as acral self-healing collodion baby whereby the patients are born with the typical membrane but limited to the hands and feet only, and after it sheds, the skin appears completely normal...

BRAF inhibitors substantially have impressive clinical efficacy in cutaneous melanoma. However, their role in acral and mucosal melanoma remains unclear. Records were reviewed of patients with metastatic or unresectable BRAF-mutant acral and mucosal melanoma hospitalized and administered BRAF inhibitors during January 2011 and March 2016. Clinical data were collected to determine PFS, ORR, DCR, OS, and safety. Among 28 acral and 12 mucosal melanoma treated with BRAF inhibitors, median PFS were 3.6 (95%CI 3...

BACKGROUND: Utilising fluorescence optical imaging (FOI), the distribution of an intravenously applied colouring agent indocyanine green (ICG) can be analysed with the potential to identify malperfusion by little to no tissue enhancement. Systemic sclerosis (SSc) is characterised by the presence of digital ulcers reflecting progressive vasculopathy. The objective was to investigate the potential of FOI in the detection of disturbed microcirculation in the hands and fingers of patients with SSc and to link FOI findings to clinical signs of ischemia such as digital ulcers and pitting scars...

Studies surveying melanomas associated with melanocytic nevi in Asia are rare. In this study, we examined whether nevus-associated melanomas differ from de novo melanomas in terms of their associations with clinical factors, histologic characteristics, and patient survival in Taiwan. Using data on cancer cases obtained from the Department of Pathology archives and the Cancer Registry of National Taiwan University Hospital, we conducted a retrospective analysis of 103 consecutive melanoma patients who were diagnosed between 2010 and 2015 and received follow-up through November 2016...

Melanoma of the skin is a common cancer only in Europeans, whereas it arises in internal body surfaces (mucosal sites) and on the hands and feet (acral sites) in people throughout the world. Here we report analysis of whole-genome sequences from cutaneous, acral and mucosal subtypes of melanoma. The heavily mutated landscape of coding and non-coding mutations in cutaneous melanoma resolved novel signatures of mutagenesis attributable to ultraviolet radiation. However, acral and mucosal melanomas were dominated by structural changes and mutation signatures of unknown aetiology, not previously identified in melanoma...

Cancer of unknown primary accounts for almost 4-5% of all invasive cancers and consists of tumors from various primary sources with considerable heterogeneity in biology and behaviour. Most of these tumors present with symptoms due to distant metastasis. Histology, immunohistochemistry and molecular profiling is the mainstay for diagnosis. In most cases of adenocarinoma associated with paraneoplastic acral vascular syndrome (PAVS), a site in the lung, ovary or uterus is discernible. Here we report a case of metastatic adenoarcinoma of unknown primary presenting as PAVS, a case which to the best of our knowledge has not been reported in published literature...

The depth of melanin in the skin can be estimated roughly by observation of the color exhibited on dermoscopy. Currently, there are no objective methods to estimate it. The aim of the present study was to clarify the relationship between the depth of melanin in the skin and the color variation exhibited, and to objectively estimate the 3-D location of melanin in the pigmented skin lesions from dermoscopic images. Representative colors in dermoscopic images of acral compound nevus, Spitz nevus and blue nevus were evaluated by the subjectively perceived color on dermoscopy and objective values in hue-saturation-lightness color space values...

Melanomas in Chinese patients show relatively higher rates of acral and mucosal types than in other populations. However, the efficacy of checkpoint inhibitor therapies against these melanoma subtypes is not well defined. We analyzed 52 patients treated with ipilimumab, pembrolizumab, or a combination of both to evaluate the efficacy and safety of checkpoint inhibitors in Chinese patients with advanced melanoma, particularly those with acral and mucosal types. The objective response rates (ORRs) were 0, 25, and 20% for ipilimumab, pembrolizumab, and pembrolizumab plus ipilimumab, respectively...

BACKGROUND: Interdigital melanoma, as a subtype of acral lentiginous melanoma, is relatively uncommon in the Caucasian population. It frequently goes unrecognized for a prolonged period of time prior to diagnosis, due to its asymptomatic nature and variable clinical appearance. METHODS: We report the case of a 67-year-old Caucasian woman who presented with interdigital malignant melanoma affecting two neighboring interdigital spaces. It had evolved over a period of more than 15 years and had been initially misdiagnosed as tinea pedis due to the macerated appearance of the lesion and a positive mycologic examination...

BACKGROUND: Acral lentiginous melanoma is a rare melanoma subtype that disproportionately afflicts people of color. Acral lentiginous melanomas have a worse prognosis than other melanomas subtypes, which has been attributed to aggressive biological behavior, more advanced stage at presentation and possible disparities in access to healthcare. OBJECTIVES: Using comprehensive patient data and long-term follow-up information in a well-characterized cohort, to examine how patient, tumor, and clinical management variables impact overall and melanoma-specific survival...

Capnocytophaga canimorsus is a bacterium transmitted through the saliva of dogs. An infection can cause severe sepsis with acral necrosis and is potentially fatal. Here, we report the case of a 41-year-old man who was infected through a wound that was licked by his dog. He went into septic shock with disseminated intravascular coagulation and subsequently lost both lower legs, his nose and all the fingers on both hands.

Darier disease is an autosomal-dominant inherited condition caused by mutation of a gene, which produces a protein involved in calcium channel regulation. The disease has a variety of manifestations and lacks consistent genotype-phenotype correlations. Acral hemorrhagic Darier disease causes macules, papules, vesicles and/or hemorrhagic blisters on the extremities. Other classic signs of the disease may be present in the same patient or relatives. Histopathology reveals dyskeratosis and suprabasal acantholysis with hemorrhagic lacunae...
