Dermoscopic features included dark brown pigmentation over the dermatoglyphics with enhanced pigmentation around the sweat pores. The pigmentation which is seen commonly over the acral areas may be mistaken for lentigines or melanoma. Identifying the classical features on dermoscopy prevents the patient from undergoing unwanted investigations.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"17 1","pages":"115 - 116"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75727250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathur","doi":"10.4103/Pigmentinternational.Pigmentinternational_36_20","DOIUrl":"https://doi.org/10.4103/Pigmentinternational.Pigmentinternational_36_20","url":null,"abstract":"Context: Amyloidosis is group of rare diseases that are characterized by extracellular deposition of abnormal amyloid proteins either involving multiple organ systems (systemic amyloidosis) or restricted to a single-tissue site, such as skin (localized amyloidosis). In primary cutaneous amyloidosis, there is deposition of amyloid in apparently normal skin. The hyperpigmentation in all the lesions of primary cutaneous macular amyloidosis gives us an insight of a possibility of a connection between amyloid fibrils and melanogenesis. Aims: To compare the melanin content from the lesional skin of upper back and surrounding non-lesional skin of macular amyloidosis. Settings and Design: A hospital based, cross-sectional study conducted over a period of 6 months. Methods and Materials: Forty-two patients (30 females and 12 males) clinically and histopathologically diagnosed as macular amyloidosis were enrolled in the study. A Mexameter MX18 was used to measure the melanin index of the lesions of Macular amyloidosis over upper back and non-affected similar areas (control). Results: The melanin index of the lesional skin of female patients ranged from 552 to 823 (mean = 705.1). The melanin index of the lesional skin of male patients ranged from 621 to 792 (mean = 697.41). In the non-affected surrounding skin of females, the mean melanin index was 357.66, whereas in males, the melanin index of the surrounding normal skin was 296.75. The P value came out to be significant, that is, <0.05 in both males and females. Conclusions: There is a possible connection between amyloid fibrils and melanin synthesis. Amyloid protein in primary macular cutaneous amyloidosis may act as the precursors for melanogenesis.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"8 1","pages":"95 - 99"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80464362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dermoscopy in LP shows variable forms of whitish structures that correlate with Wickham striae (WS), vascular structures, and pigmentary changes that aid in its diagnosis. Aim: To study the correlation between clinical and dermatoscopic features in cutaneous variants of LP in Indian skin. Method: Patients with LP presenting over a period of 1 year were included. Dermoscopy of the lesions in polarized mode was done using video dermatoscope − Dino-Lite Premier AM4113ZT model. Both clinical and dermoscopy findings were photographed, recorded, and studied. Result: Fifty-six percent patients (39/70) had classical LP (CLP), 14% patients (10/70) had hypertrophic LP which were the most common clinical variants. Reticulate pattern of WS was the most common pattern observed in 40% (28/70) cases and a new rosette pattern of WS was observed in 13% (9/70) cases. Nonvascular findings such as WS, comedo-like openings, and grey blue dots showed statistically significant association with CLP. Among the pigmentary findings, pepper-like pigmentation was seen in 64% (25/39) CLP and reticulate pattern of pigmentation in 85% (6/7) cases of LP pigmentosus. Perifollicular pigmentation showed statistical significance in 100% cases of lichen planopilaris. Conclusion: In view of consistent dermoscopic features observed in LP, it aids as a valuable noninvasive diagnostic tool, many a times obviating the need for skin biopsy. Limitations: Small sample size and the exclusion of lesions of LP over the nails, genitals, and oral mucosa.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"39 1","pages":"100 - 108"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76331938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis is generally based on history and clinical features. In the situation of diagnostic dilemma, dermoscopic examination is the quick and easiest method to solve the clinical uncertainty and thereby avoid unnecessary biopsies. Objectives: The aims of the study were to describe the varied clinical presentations and to enumerate the dermoscopic features of IGH. Methods: Study was conducted after obtaining approval from Institutional Ethics Committee. All the patients presenting with IGH attending the Department of Dermatology were examined and enrolled for the study after taking written informed consent. Each subject was evaluated by detailed personal history, clinical examination and dermoscopic examination. Results: A total of 100 patients of IGH were included in the study. The most affected age group was 46–65 years (52%). Females were most commonly affected with M: F ratio 1:1.17. Different dermoscopic patterns of IGH documented were amoeboid (58.2%), feathery (19.1%), petaloid (14.5%) and nebuloid (8.2%). Ten percent of the patients showed more than one patterns. Conclusion: Dermoscope aids in evaluation of different patterns of IGH lesions, which helps to differentiate it from other hypopigmented conditions with considerable overlap in the site, morphology and clinical features. Dermoscopic analysis makes it easier to diagnose the disorder and subsequently plan for the appropriate treatment.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"42 1","pages":"25 - 29"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77997954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such misuse of topical corticosteroids leads to unwanted physical and psychological side-effects which have been collectively described as “Topical steroid dependent/damaged face” (TSDF).
