Tips for difficult to diagnose hypomelanotic melanomas on reflectance confocal microscopy.

Amelanotic/hypomelanotic melanoma (AHM) represents a clinical diagnostic challenge. Dermoscopy improves AHM diagnosis thanks to visualization of little pigment and vascular pattern. Reflectance confocal microscopy (RCM) increases further the diagnostic accuracy of AHM but few and small studies have described in detail RCM features of AHM.

In vivo reflectance confocal microscopy of halo nevi.

Introduction: Halo nevi named also Sutton's nevi are uncommon melanocytic lesions occurring especially among adolescents. There are two effective diagnostic methods: dermoscopy and in vivo reflectance confocal microscopy (RCM), which can help us to observe many structural elements and characteristic features of Sutton's nevi.

Objectives: The aim of this study was to describe reflectance confocal microscopy features of halo nevi.

A Comparative Study of Pigmented and Non-pigmented Basal Cell Carcinoma in Reflectance Confocal Microscopy.

Background/aim: Basal cell carcinoma (BCC) is a common skin cancer, especially in the elderly population. The probability of BCC development increases past the age of 55. Dermoscopy and reflectance confocal microscopy (RCM) are two modern tools useful in the diagnosis of BCC.

Dermoscopic Findings in the Presurgical Evaluation of Basal Cell Carcinoma. A Prospective Study.

Background: Surgery is the best treatment for basal cell carcinoma (BCC); however, incomplete excisions are possible.

Objective: Assessment of the accurateness of dermoscopy and clinical evaluation in the detection of borders of BCC and description of dermoscopic findings in clinically healthy tissue surrounding BCC.

Materials And Methods: Eighty-eight lesions with clinical dermoscopic diagnosis of BCC were examined clinically and dermoscopically, to delineate the correct site of surgical incision, demarcating the respective margins with colred dermographic pencils.

Features of dermatofibroma in reflectance confocal microscopy.

Background: Dermatofibroma (DF) is a common benign skin lesion in a majority of cases located on the legs or upper limbs. The etiology of DF is still unclear.

Objectives: Reflectance confocal microscopy features of DF were described.

Pattern of response of unresectable and metastatic cutaneous squamous cell carcinoma to programmed death-1 inhibitors: A review of the literature.

Cutaneous squamous cell carcinoma (cSCC) is the second most frequent nonmelanoma skin cancer (NMSC). The majority of in situ cSCC [cSCC (Tis)] can be cured surgically, while local advanced and metastatic ones require other treatments, but there are no therapies approved by U.S.

Current therapies for actinic keratosis.

Actinic keratosis (AK) is a very common skin disease caused by chronic sun damage, which in 75% of cases arises on chronically sun-exposed areas, such as face, scalp, neck, hands, and forearms. AKs must be considered an early squamous cell carcinoma (SCC) for their probable progression into invasive SCC. For this reason, all AK should be treated, and clinical follow-up is recommended.

Targetoid erythema surrounding multiple seborrheic keratoses induced by chemotherapy with gemcitabine.

The cutaneous adverse effects of gemcitabine include allergic skin rash frequently associated with pruritus, alopecia, sweating, dermatitis with boils, and ulcerations. We report the case of a patient that developed inflammation of seborrheic keratoses after gemcitabine treatment.

Dermatoscopic features of Koebner phenomenon in lichen planus on light and dark skin.

The Koebner phenomenon is well described and well known in clinical practice. Sometimes it can take on a linear appearance, the diagnosis of which can be facilitated by the use of dermatoscopy. In this case, we present a comparison between a linear Koebner phenomenon on light and dark skin, reporting the salient dermatoscopic characteristics and relating them to histopathology.

Overview on the treatment of Lyme disease in pregnancy.

Lyme disease is a tick-borne illness, which is typically caused by Borrelia Burgdoferi. Over time, a typical Borreliosis skin reaction takes shape, i.e.
