RESUMEN

Introduction: Chemotherapy-induced alopecia (CIA) can seriously affect the quality of life of cancer patients. Trichoscopic patterns and confocal microscopy (RCM) features of CIA have been scarcely studied. This study aimed to investigate the dermoscopic and RCM features of CIA in 19 females and 5 males, with CIA due to current or recent chemotherapy. Methods: Patients with CIA and current or recent (within 2 months) history of chemotherapy treatment were enrolled. After clinical examination, standard pictures were taken by digital camera (SLR Canon PowerShot G10) and trichoscopic images were captured by the Handyscope device (20x). Images of RCM were acquired by VivaScope 3000 with the VivaStack option. The trichoscopic and confocal images were acquired by three independent observers after central parting on three areas: vertex, middle, and frontal scalp. Results: A total of 24 patients were enrolled. CIA has features of anagen effluvium at trichoscopy but with low frequency of yellow dots and prominence of black dots. The simultaneous presence of pseudo-monilethrix and black dots at trichoscopy confirms the hypothesis that chemotherapy insults the hair follicle intermittently. At RCM, the presence of abnormal hair shaft morphology highlights that the insults affect hair shaft production. Conclusion: These are the first data in this field, so further studies with a higher number of patients analyzed are needed to confirm these findings.

RESUMEN

BACKGROUND: Frontal fibrosing alopecia (FFA) is a scarring alopecia that mainly affects postmenopausal women characterized by recession of the frontotemporal hairline and eyebrow loss. Current techniques to assess FFA activity are limited and involve noninvasive tools that assess disease progression or an invasive technique such as scalp biopsies. However, since progression of FFA is very slow, it is very important to develop a noninvasive technique to assess disease activity to monitor treatment response. OBJECTIVES: To provide a standardized and objective method to assess FFA activity. METHODS: We evaluated the correlation between trichoscopy and pathological features (degree of lymphocytic infiltration) in 20 dermoscopy-guided biopsies of FFA. At trichoscopy, we divided the severity of peripilar casts into 3 grades according to their thickness. To validate the trichoscopic visual scale, we showed the images to 7 dermatologists with interest in hair diseases. Concordance was assessed using the Kendall Tau-b concordance test. RESULTS: A strong correlation between severity of peripilar casts at trichoscopy and degree of lymphocytic infiltrate was observed by the Kendall Tau-b test. Validation showed very good inter- and intraobserver agreement. CONCLUSION: The trichoscopic visual scale allows noninvasive assessment of scalp inflammation in FFA in different scalp regions and therefore provides optimal guidance for treatment.

RESUMEN

BACKGROUND: Onychotillomania is a nail-picking disorder characterized by nail dystrophy and abnormal morphology of the nail plate, nail bed, and periungual skin. OBJECTIVE: The purpose of this study was to describe the dermoscopic features of onychotillomania. METHODS: A retrospective study of the dermoscopy images of 36 patients affected by onychotillomania. The images were reviewed independently by both authors and a list of dermatoscopic findings was established. RESULTS: Scales were observed in 34 cases (94.4%). Absence of the nail plate was seen in 30 cases (83.3%). Wavy lines were observed in 25 cases (69.4%). Hemorrhages were observed in 23 cases (63.9%). Crusts were seen in 22 cases (61.1%). Nail bed pigmentation was observed in 17 cases (47.2%). Speckled dots were observed in 14 cases (38.9%). Nail plate melanonychia was observed in 4 cases (11.1%). LIMITATIONS: Limitations included small sample size and retrospective study. CONCLUSION: Absence of the nail plate with multiple obliquely oriented nail bed hemorrhages, nail bed gray pigmentation, and presence of wavy lines are characteristic findings of onychotillomania and not seen in other nail diseases.

RESUMEN

The elderly population is growing, lifespans are increasing, and a greater emphasis on geriatric care is being implemented in hospital systems. With a higher percentage of the population living longer, hair and nail diseases associated with the advanced stages of life are becoming more prevalent. Common hair diseases in the elderly include androgenetic alopecia, senile alopecia, frontal fibrosing alopecia, and erosive pustular dermatosis of the scalp. Nail diseases associated with advanced age include onychomycosis, brittle nails, onychocryptosis, onychoclavus, onychogryphosis, subungual hematomas, subungual exostosis, myxoid cysts, and malignancies. These diseases can have a serious impact on a patient's quality of life. In an effort to familiarize the reader with these common changes and abnormalities, we discuss hair and nail diseases in the mature patient.

RESUMEN

A 14-year-old Hispanic boy presented with a 0.25-mm wide, sharply demarcated, dark brown band of longitudinal melanonychia of the left thumbnail. A clinical diagnosis of nail matrix nevus was made and the boy was scheduled for follow-up. The band showed proximal fading after 6 months and had completely faded after 11 months, with the proximal nail fold showing small dark brown dots on dermoscopy. We documented the spontaneous regression of melanonychia over 11 months.

RESUMEN

INTRODUCTION: Hair shedding is a common consequence of the normal hair cycle that changes with internal and external factors. Female pattern hair loss (FPHL) is difficult to assess in terms of shedding severity as the conscious perception of hair shedding varies according to each individual, and most utilized methods are semi-invasive or very time consuming. In this study, we establish and validate a hair-shedding scale for women with thick hair of different lengths. METHODS: A visual analog scale was developed for thick hair of short, medium, and long lengths by dividing a bundle of hairs of each length into nine piles of increasing hair amount that were then photographed and arranged in order of size. Twenty women with no FPHL with each length of hair (60 total) were asked to select the photographed hair bundle that best correlated with the amount of hair they shed on an average day. A total of 94 women with FPHL with excessive shedding were then asked to repeat the same process. RESULTS: Women with no FPHL and short, medium and long hair had mean shedding scores of 2.5, 2.35 and 2.4, respectively. Women with FPHL and short, medium and long hair had mean shedding scores of 7.25, 7.0 and 7.14, respectively. Statistically significant Spearman's ρ coefficient and κ coefficient demonstrated correlation and inter-observer reliability. CONCLUSION: Our results show that women with FPHL not only shed considerable hair more than women with no FPHL, but that this hair-shedding visual scale is a fast and effective method of evaluating hair-shedding amounts in an office setting.
