Cutaneous leishmaniasis is usually transmitted by infected phlebotomine sand fly bites that initiate local cutaneous lesions. Few reports in the literature describe other modes of transmission. We report a case of a previously healthy 59-year-old woman who underwent electrocoagulation to remove seborrheic keratosis confirmed by dermatoscopy. Three months later, a skin fragment tested positive for Leishmania culture; the parasite was identified as L. (V.) braziliensis. Trauma may generate inflammatory cascades that favor Leishmania growth and lesion formation in previously infected patients...

BACKGROUND: The term balanitis includes a variety of inflammatory skin diseases involving the glans penis whose clinical diagnosis may be challenging. A biopsy is often required to obtain a definitive diagnosis, although it is barely accepted by patients. Reflectance confocal microscopy (RCM), that provides a real-time, en face imaging of the epidermis and upper dermis, is currently utilized for the diagnosis of some neoplastic and inflammatory skin diseases. The aim of this study was to analyze the RCM handheld findings of some common balanitis and to correlate them with dermatoscopy and histopathological features...

BACKGROUND: Lentigo maligna (LM), a form of melanoma in situ, is treated to prevent progression to lentigo maligna melanoma (LMM). Surgical treatment is the gold standard. However, treatment guidelines are based on expert opinion and comparative studies are lacking. OBJECTIVE: The objective of this study is to assess the diagnostic methods and clinical management of LM patients among European dermatologists and residents. METHODS: A survey consisting of 29 questions about diagnostic methods and treatment options used for LM patients was sent to 3308 members of the European association of Dermatologists and Venereologists (EADV)...

Trichoscopy has become an essential tool for the diagnosis of various diseases that affect the hair and scalp. Through dermatoscopy we identified a set of findings that share a circular shape of hair shafts. The objective of this study is to distinguish among the various forms of circular hairs in order to identify their peculiarities and to describe in which skin disorders they can be found.

Cutaneous Melanoma (CM) is a malignant tumour, and is one of the most rapidly growing cancers. Discovering a melanoma in the early stages of the disease is extremely difficult and, as such, only an invasive disease stage can be identified easily with the naked eye. Dermatoscopy is a diagnostic method intended to maximise early detection of CM performed by the dermatoscopy system. To address the limitations of existing systems a novel, wireless digital dermatoscopy system is presented for providing high-resolution images...

One step melanoma surgery is, in fact, an innovative combined method for diagnosis and treatment of cutaneous melanoma (at the same time). The methodology allows an accurate assessment of the actual status of the affected patients by 1) clinical status, dermatoscopy, high-frequent ultrasonography (HFUS) of the pigmented lesion (eventually in combination with normal lymph nodes ultrasonography), followed by a single surgical intervention. Within this intervention, the primary tumour is removed with the appropriate surgical field, with or without parallel detection and draining lymph node biopsy (depending on the established tumour thickness)...

Traction alopecia was first described in 1904 but is still a cause of scarring hair loss in young women worldwide. It is unique in being initially a reversible then an irreversible (scarring) form of alopecia. Linked to tightly-pulled hairstyles, it is seen across all races. The pattern of hair loss depends on the style creating it but most commonly affects the frontotemporal hairline. There are some new examination findings associated with traction alopecia, which are traction folliculitis, the fringe sign and hair casts (pseudonits) on dermatoscopy...

BACKGROUND: Acquired dermal macular hyperpigmentation (ADMH) is a hypernym encompassing Riehl's melanosis, lichen planus pigmentosus, and ashy dermatoses that show significant clinicopathological overlap. We sought to describe the dermatoscopic features of ADMH and correlate them with histopathological findings. METHODS: This was a prospective observational study performed in two phases. A detailed clinical and dermatoscopic examination was performed, and skin biopsies were obtained in 51 patients...

BACKGROUND: Nonpigmented skin cancer is common, and diagnosis with the unaided eye is error prone. OBJECTIVE: To investigate whether dermatoscopy improves the diagnostic accuracy for nonpigmented (amelanotic) cutaneous neoplasms. METHODS: We collected a sample of 2072 benign and malignant neoplastic lesions and inflammatory conditions and presented close-up images taken with and without dermatoscopy to 95 examiners with different levels of experience...

Monilethrix is a rare genodermatosis with high penetrance and variable expressivity. This is a case report of a Danish family with varying phenotypical presentations. The family members were diagnosed using dermatoscopy and microscopy, which were subsequently supported by gene sequence analysis. No cure of monilethrix exists, but a single case report shows promising results using low dosage of oral minoxidil. Reducing hair dressing trauma to diminish weathering remains the best prophylaxis.

The large-scale deployment of low-cost, noninvasive mechanisms of early detection are needed to reduce the melanoma burden. A serial 2-step system could power mass screening efforts serving the uninsured and underinsured as well as the rural and remote US counties where melanoma mortality is doubled for lack of access to dermatologists. Furthermore, serial melanoma screening strategies, serial total body photography and serial digital dermatoscopy imaging may be performed as a telehealth service, and thus would be available in any location that can support activity compliant with the Health Insurance Portability and Accountability Act and has appropriate bandwidth...

Lichen planopilaris is a form of lymphocyte-mediated primary cicatricial alopecia characterized by perifollicular scaling progressing to patches of alopecia depending on the clinical variant. The course is relentlessly progressive and chronic. Hence, early diagnosis and institution of therapy are imperative to halt the disease progress. Although definitive diagnosis is made by scalp biopsy, the detection is usually delayed. Dermatoscopy helps in early recognition of this condition which at that stage is clinically invisible...

Myiasis, infestation of live human and vertebrate animals by larvae, can complicate ulcers and open wounds. Although myiasis occurs in neglected erosions of pemphigus, such a complication is not documented in the literature. Herein, we report a case of myiasis complicating pemphigus vulgaris and describe its dermatoscopic features.

Facial melanoma is difficult to diagnose and dermatoscopic features are often subtle. Dermatoscopic non-melanoma patterns may have a comparable diagnostic value. In this pilot study, facial lesions were collected retrospectively, resulting in a case set of 339 melanomas and 308 non-melanomas. Lesions were evaluated for the prevalence (> 50% of lesional surface) of 7 dermatoscopic non-melanoma features: scales, white follicles, erythema/reticular vessels, reticular and/or curved lines/fingerprints, structureless brown colour, sharp demarcation, and classic criteria of seborrhoeic keratosis...

Sebaceoma associated with seborrheic keratosis has only been described once in the literature. Herein, we present an additional case in a 69-year-old woman who complained of a multicolored plaque on the left breast. Dermatoscopy showed a central orange lesion with orange globules suggestive of dilated glands. The periphery of the lesion was brown and gray, with some more pigmented zones. The histopathological study demonstrated a seborrheic keratosis in the peripheral areas, whereas the central part of the lesion was a sebaceoma...
