Abstract
There is a need for adjuvant imaging techniques that would allow reducing the number of slow Mohs stages. This study aimed to evaluate the use of dermoscopy in the demarcation of basal cell carcinoma (BCC) surgical margins for slow Mohs surgery. This was a retrospective study over 3 years (2016-2019), including patients with BCC excised using slow Mohs surgery. On the basis of the treatment received, the patients were divided into 2 groups: group 1 (28 BCC) and group 2 (26 BCC). In group 2, BCC margins were demarcated using dermoscopy. A total of 54 patients were enrolled in the study. The number of positive lateral margins was significantly lower in the group where BCC margins were demarcated using dermoscopy (19% vs 53%, P = .012). In this group, the number of Mohs stages needed to achieve complete clearance was significantly lower. However, the mean interval between the first Mohs excision and Mohs clearance was not significantly different between the 2 groups (9 ± 4 vs 12 ± 7 days). In conclusion, preoperative dermoscopy is useful for reducing the number of positive lateral margins and the number of slow Mohs stages in treating BCC especially pigmented tumors.

J Cutan Pathol 2020; 47:794-799.

Abstract
BACKGROUND Determination of BRAF status is mandatory for targeted therapy but it is not currently available in most developing countries. AIM We aimed to analyze BRAF mutations in a series of cutaneous melanoma of Tunisian patients and to compare BRAF V600E mutation detection by immunohistochemistry to DNA sequencing. PATIENTS AND METHODS Archival formalin fixed paraffin embedded tissues from 28 patients with primary cutaneous melanoma were evaluated for the BRAF mutations by Sanger sequencing and immunohistochemistry. RESULTS BRAF mutations were detected in 19/28 (68%) of analyzed tumors. The sensitivity and specificity of immunohistochemistry compared to DNA sequencing for identification of the BRAF V600E mutation were 100%. We found five novel mutations, one of them had deleterious effect. CONCLUSION The present study shows an intermediate frequency of mutations of the BRAF gene in cutaneous melanoma of Tunisian patients, and supports the use of immunohistochemistry as a screening test for the assessment of the BRAF V600E status in the management of melanoma in clinical practice.

Abstract
Dermoscopy is a useful tool that helps distinguish lupus miliaris disseminatus faciei (LPDF) from sarcoidosis and tuberculosis. Follicular keratotic plugs (FKP) represent the hallmark of LPDF. Dermoscopic aspect of LPDF changes through the course of the disease.

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2020; 36:339-350.

Abstract
BACKGROUND Rickets is a common disease worldwide. In the developed world, its prevalence dramatically decreased but still diagnosed in at-risk populations. The skin plays a critical role in vitamin D synthesis. Therefore, several skin diseases, especially keratinization disorders, could lead to impaired vitamin D metabolism and vitamin D deficient rickets. OBJECTIVE The article aimed to summarize the current knowledge of skin diseases and conditions associated with rickets. METHODS To examine the association between rickets and skin diseases, we performed a systematic review of the literature using PubMed database. The search included studies published from the database inception to August 2019. RESULTS A total number of 75 articles were included. Identified conditions associated with rickets were ichthyosis being a more common skin diseases, alopecia, epidermal and melanocytic nevi, xeroderma pigmentosum, mastocytosis, psoriasis, and atopic dermatitis. Three types of rickets were identified: vitamin D-dependent rickets, hypocalcemic vitamin D-dependent rickets type 2, and hypophosphatemic rickets. Cutaneous skeletal hypophosphatemia syndrome is a newly described and under-recognized condition. It is defined by the association of epidermal or melanocytic nevi, hypophosphatemic rickets, and elevated levels of fibroblast growth factor 23. Rickets in patients with ichthyosis was mainly due to impaired ability of ichthyotic skin to synthesize vitamin D, poor UV penetration of the skin caused by keratinocyte proliferation, and dark phototype. The latter may be considered a risk factor for rickets in patients with ichthyosis. CONCLUSION Despite its rarity, these associations should be properly recognized by dermatologists. Early diagnosis of rickets is important to prevent growth retardation and skeletal deformities.
