Melanocytic lesions ≤ 6mm: Prospective series of 481 melanocytic trunk and limb lesions in Brazil.

PLoS One 2021 8;16(6):e0252162. Epub 2021 Jun 8.

National Cancer Institute, Rio de Janeiro, Brazil.

Early diagnosis when melanoma is still small and thin is essential for improving mortality and morbidity. However, the diagnosis of small size melanoma might be particularly difficult, not only clinically but also dermoscopically. This study aimed to define clinical and dermatoscopic parameters in the diagnosis of suspicious pigmented cutaneous lesions with a diameter of ≤ 6mm and determine the sensitivity, specificity, positive and negative predictive values as well as the accuracy of each clinical and dermatoscopic criterion.

Current Diagnosis and Treatment Options for Cutaneous Adnexal Neoplasms with Apocrine and Eccrine Differentiation.

Int J Mol Sci 2021 May 11;22(10). Epub 2021 May 11.

Department of Soft Tissue/Bone Sarcoma and Melanoma, Maria Sklodowska-Curie National Research Institute of Oncology, 02-781 Warsaw, Poland.

Adnexal tumors of the skin are a rare group of benign and malignant neoplasms that exhibit morphological differentiation toward one or more of the adnexal epithelium types present in normal skin. Tumors deriving from apocrine or eccrine glands are highly heterogeneous and represent various histological entities. Macroscopic and dermatoscopic features of these tumors are unspecific; therefore, a specialized pathological examination is required to correctly diagnose patients. Read More

Effects of metformin on experimentally induced acne on rabbit ear.

Exp Dermatol 2021 Apr 13. Epub 2021 Apr 13.

Department of Dermatology, Venereology and Leprology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Evidence for the effectiveness of metformin in the treatment of acne is limited.

In another group, to check whether metformin pre-treatment affects subsequent comedone development by IM, metformin was given for 14 days and then withdrawn (14 days) followed by comedone development with IM and metformin treatment.

Skin Diseases Classification Using Deep Leaning Methods.

Curr Health Sci J 2020 Apr-Jun;46(2):136-140. Epub 2020 Jun 30.

Faculty of Mechanics, University of Craiova, Craiova, Romania.

Due to the high incidence of skin tumors, the development of computer aided-diagnosis methods will become a very powerful diagnosis tool for dermatologists. The skin diseases are initially diagnosed visually, through clinical screening and followed in some cases by dermoscopic analysis, biopsy and histopathological examination. Automatic classification of dermatoscopic images is a challenge due to fine-grained variations in lesions. Read More

Dermatoscopy in life-threatening and severe acute rashes.

Clin Dermatol 2020 Jan - Feb;38(1):113-121. Epub 2019 Nov 11.

Institute of Dermatology, Santa Maria della Misericordia University Hospital, Udine, Italy.

A prompt recognition of life-threatening and severe acute rashes is of utmost importance to start an appropriate therapy as soon as possible. Consequently, clinicians often must rely only on clinical data to make a diagnosis because some diagnostic procedures may take a relatively long time to be performed (eg, histologic examination, microbiologic tests). In this scenario, dermatoscopy may be useful as an auxiliary tool to support the diagnosis by highlighting subclinical features. Read More
