RESUMO

Actinic keratoses are dysplastic proliferations of keratinocytes with potential for malignant transformation. Clinically, actinic keratoses present as macules, papules, or hyperkeratotic plaques with an erythematous background that occur on photoexposed areas. At initial stages, they may be better identified by palpation rather than by visual inspection. They may also be pigmented and show variable degrees of infiltration; when multiple they then constitute the so-called field cancerization. Their prevalence ranges from 11% to 60% in Caucasian individuals above 40 years. Ultraviolet radiation is the main factor involved in pathogenesis, but individual factors also play a role in the predisposing to lesions appearance. Diagnosis of lesions is based on clinical and dermoscopic examination, but in some situations histopathological analysis may be necessary. The risk of transformation into squamous cell carcinoma is the major concern regarding actinic keratoses. Therapeutic modalities for actinic keratoses include topical medications, and ablative and surgical methods; the best treatment option should always be individualized according to the patient.

RESUMO

Introduction: Dermatoscopy is an innovative non-invasive technique for clinical morphology of pigmented lesions and skin tumor. The purpose of our study was to highlight the morphological and dermoscopic features of basal cell carcinoma (CBC) in our study population. Methods: We conducted a prospective unicentric study over a period of 2 years. We used dermoscopy in all patients with BCC. Statistical analysis was performed using SPSS software version 17. Results: The study included 100 patients with BCC, the average age of patients was 51.87 years, with a sex ratio F/M = 0.6. BCC most commonly occurred in the face and most patients were prototype III and IV. We established conventional and non-conventional dermatoscopic criteria. Our study showed that there is a significant relationship between prototype and the degree of BCC pigmentation. Conclusion: This study highlighted the key role of dermoscopy in detecting small-sized BCC and in facilitating the diagnosis of pigmented BCC.

RESUMO

Dissecting cellulitis is an inflammatory, chronic, and recurrent disease of the hair follicles that mainly affects young Afro-descendent men. Trichoscopy is a method of great diagnostic value for disorders of the scalp. Clinical and trichoscopic findings of dissecting cellulitis are heterogeneous and may present features common to non-cicatricial and scarring alopecia. This article presents the trichoscopic findings of dissecting cellulitis that help in the diagnosis and consequent institution of the appropriate therapy and better prognosis of the disease.

RESUMO

Tinea incognito resulting from corticosteroid abuse is becoming very common in the tropics. Its diagnosis is tricky owing to its confusing morphology, as well as practical and technical issues associated with mycological tests. Dermoscopy has now evolved as a novel diagnostic tool for diagnosing tinea incognito in such challenging situations, since the typical hair changes such as Morse-code hairs, deformable hairs, translucent hairs, comma and cork screw hairs, and perifollicular scaling may be seen despite steroid use, irrespective of mycological results.

RESUMO

BACKGROUND: Frontal fibrosing alopecia is a condition of unknown origin, histologically similar to classic lichen planopilaris and generally observed in postmenopausal women with alopecia of the frontal-temporal hairline. OBJECTIVES: To describe the clinical, dermatoscopic, and histopathological characteristics and the treatment used in patients who have frontal fibrosing alopecia at the Alopecia Outpatient Clinic in a university hospital. METHODS: Retrospective descriptive study performed by reviewing medical charts and biopsies of the scalp. RESULTS: Sixteen patients were analyzed, all of them female, 93.75% of them postmenopausal, and 56.25% brown-skinned. All had frontal alopecia (100%), followed by temporal alopecia (87.5%) and madarosis (87.5%). On dermatoscopy, perifollicular erythema and tubular scales were found as a sign of disease activity. Of the patients, 68.75% had associated autoimmune diseases, including lupus, thyroid disease and vitiligo. Of the 13 biopsies from 8 patients, 10 showed microscopic aspects compatible with frontal fibrosing alopecia. Laboratory tests did not show major abnormalities and minoxidil was the most used treatment. STUDY LIMITATION: Data collection limited by the study's retrospective design associated to flaws while filling in the medical charts and absence in standards to the collection and processing of the pathology and histopathological examination. CONCLUSIONS: A demographical, clinical, and histopathological description of 16 patients diagnosed with frontal fibrosing alopecia, which remains a challenging disease, of unknown origin, and frequently associated with autoimmune diseases. This study reinforces literary findings. However, more research is needed to establish the pathogenesis and effective treatments.

RESUMO

El granuloma aséptico facial idiopático (GAFI) es una patología específica de la edad pediátrica caracterizada por la aparición de nódulos rojizos asintomáticos en la región facial. Su etiopatogenia es aún motivo de discusión, aunque la literatura actual orienta a que se encontraría dentro del espectro de la rosácea infantil. Tiene una evolución crónica pero benigna, y hay publicaciones que documentan la resolución espontánea de las lesiones en menos de un año. A pesar de no tener un tratamiento bien definido, se prefiere que sea conservador y se eviten las intervenciones agresivas


Idiopathic facial aseptic granuloma is a pediatric skin condition involving asymptomatic reddish nodules. The etiology and pathogenesis is still under discussion, although the literature tends to place this condition within the spectrum of childhood rosaceas. The clinical course is chronic but benign, and cases have been reported to resolve spontaneously in less than a year. Even though no well-defined treatment has emerged, a conservative approach that avoids aggressive therapies is preferred

RESUMO

BACKGROUND: Talaromyces marneffei is a thermally dimorphic fungus endemic in south-east Asia. It predominantly occurs in both immunocompromised and immunosuppressed patients and can be fatal if diagnosis and treatment are delayed. The clinical manifestations of T. marneffei infection are nonspecific and rapid diagnosis of T. marneffei infection remains challenging. CASE PRESENTATION: A 24-year-old man came to our outpatient department with the sign of common skin lesions. The lesions were cuticolor follicular papules with or without central umbilication, nodules and acne-like lesions, which are common in syringoma, steatocystoma multiplex and trichoepithelioma. A dermatoscopy examination was performed to differentiate these skin lesions. The dermatoscopic images revealed circular or quasi-circular whitish amorphous structure with a central brownish keratin plug, providing the diagnostic clues of T. marneffei infection. Therefore, a skin scrapings culture, skin biopsy and serological detection for human immunodeficiency virus (HIV) were performed. The final diagnosis of this patient was T. marneffei and HIV co-infection. CONCLUSION: Rapid diagnosis of T. marneffei infection is clinically challenging since presenting clinical manifestations are nonspecific with significant overlap with other common conditions. This case highlights that dermatoscopy is a promising tool for the rapid diagnosis of T. marneffei infection in patients with nonspecific skin lesions, assisting clinicians to avoid delayed diagnosis or misdiagnosis.

RESUMO

BACKGROUND: Skin aging can be classified as either physiological or pathological aging. Pathological aging is most often due to chronic sunlight exposure (photoaging). Age-dependent changes in dermoscopic features of normal skin have not previously been well defined. OBJECTIVES: We compared the dermoscopic features of skin from non-elderly subjects, elderly subjects with physiological aging, and elderly subjects with photoaging. MATERIALS AND METHODS: We enrolled 40 non-elderly subjects aged 20-60 years, 40 elderly subjects aged >60 years with physiological aging, and 40 elderly subjects aged >60 years with photoaging. Skin from the lower legs of subjects was examined by dermoscopy. RESULTS: Compared with non-elderly subjects, dermoscopic examination of elderly subjects with physiological aging and photoaging revealed various degrees of xerosis (mild: scaling limited to skin furrows; moderate: scaling extending beyond skin furrows with accentuation of skin markings; severe: plate-like scaling extending beyond skin furrows with formation of deep skin fissures). In addition, dermoscopic examination of skin from elderly subjects with photoaging showed increased prevalence of uneven pigmentation (small brown globules, reticular pigmentation, and homogeneous pigmentation in a patchy distribution) and vascular telangiectasia (linear and branching vessels). CONCLUSION: This study provides a novel dermoscopic grading system to evaluate the severity of xerosis and demonstrates the application of dermoscopy for the accurate assessment of subtle morphological changes (including pigmentation pattern and vascular structures) associated with physiological aging and photoaging.

RESUMO

Cancer is one of the leading causes of deaths in the last two decades. It is either diagnosed malignant or benign - depending upon the severity of the infection and the current stage. The conventional methods require a detailed physical inspection by an expert dermatologist, which is time-consuming and imprecise. Therefore, several computer vision methods are introduced lately, which are cost-effective and somewhat accurate. In this work, we propose a new automated approach for skin lesion detection and recognition using a deep convolutional neural network (DCNN). The proposed cascaded design incorporates three fundamental steps including; a) contrast enhancement through fast local Laplacian filtering (FlLpF) along HSV color transformation; b) lesion boundary extraction using color CNN approach by following XOR operation; c) in-depth features extraction by applying transfer learning using Inception V3 model prior to feature fusion using hamming distance (HD) approach. An entropy controlled feature selection method is also introduced for the selection of the most discriminant features. The proposed method is tested on PH2 and ISIC 2017 datasets, whereas the recognition phase is validated on PH2, ISBI 2016, and ISBI 2017 datasets. From the results, it is concluded that the proposed method outperforms several existing methods and attained accuracy 98.4% on PH2 dataset, 95.1% on ISBI dataset and 94.8% on ISBI 2017 dataset.

RESUMO

A case of multiple xanthogranulomas located bilaterally on arms, armpits, legs, trunk, abdomen, scalp, neck and plantar surfaces in a 25-year-old man is reported. The patient was evaluated by polarised light dermoscopy and reflectance confocal microscopy (RCM) that showed peculiar aspects. In particular, dermoscopy showed a homogeneous orange-yellowish hue that is related to the histopathological presence of foamy histiocytes and Touton giant cells; the last typically appeared at RCM as peculiar giant cells surrounded by highly refractive ring due to the cytoplasm rich of lipids. Laboratory investigations, including routine haematological examination, liver and renal function tests, serum lipid and sugar levels were normal. The patient started isotretinoin 20 mg once daily. After 6 months, some lesions flattened, leading to yellowish or hyperpigmented macules, but new lesions raised up.

RESUMO

Eccrine porocarcinoma (EPC) is a rare malignant skin tumor. The dermoscopy of invasive EPC reveals focal presence of whitish-pink, structureless areas surrounded by pinkish-white halos. In an eccrine poroma (EP), such areas present diffuse distribution in the "frog- eggs" pattern. We reported an EPC in situ that presents a transitional dermoscopy pattern between EP and invasive EPC. We found a diffuse distribution; whitish-pink, structureless areas surrounded by pinkish-white halos; a central exulceration and a polymorphic vascular pattern.

RESUMO

Dermoscopic studies about cutaneous metastases of malignant melanoma (CMMM) are few. Our objective was to analyze the dermoscopic features of CMMM and propose a new dermoscopic pattern classification based on color pigmentation and some specific dermoscopic features. A retrospective evaluation of 150 dermoscopic images of CMMM taken from 40 patients was performed. One hundred CMMM images were individually evaluated by six dermatologists in order to classify them according to four dermoscopic patterns: (i) blue pattern; (ii) pink pattern; (iii) brown pattern; and (iv) mixed pattern. One hundred and fifty dermoscopic images including 50 CMMM and 100 benign lesions were evaluated by five dermatologists to calculate the accuracy of these patterns in the recognition of CMMM. An intra- and interobserver reproducibility agreement study between all different dermoscopic pattern classifications was performed. Seventy-five percent of our cases of CMMM showed a monochromatic pattern. Light brown pigmented halo, peripheral gray spots and polymorphic atypical vessels were the most significant focal dermoscopic structures. The reproducibility of the color-based dermoscopic pattern classification was superior to previous dermoscopic pattern classification. In summary, a dermoscopic pattern classification based on color pigmentation and some specific dermoscopic features may be useful in recognizing early cutaneous melanoma metastasis. Multicentric studies are recommended in order to lower the impact of interobserver variability.

RESUMO

Background: The collagen vascular disorders, particularly systemic sclerosis, dermatomyositis, systemic lupus erythematosus and mixed connective tissue disorder, are often characterized by microangiopathic abnormalities of the nail folds. Nail fold dermoscopy is a well-established technique to assess these vascular changes. Aims: To evaluate finger nail capillary vascular abnormalities by dermoscopy and their correlation with cutaneous and systemic involvement in the patients of collagen vascular disorders. Methods: This was a cross-sectional study involving patients of collagen vascular disorders presenting to Government Medical College, Amritsar over a period of 2 years. Nail fold dermoscopy was done in these patients and correlated with cutaneous and systemic involvement. Statistical analysis was done using SPSS 17.0 version. Results: A total of 30 patients were enrolled in the study. Sixteen (53.3%), 11 (36.7%) and 3 (10%) patients of systemic sclerosis, systemic lupus erythematosus and mixed connective tissue disorder, respectively were included for nail fold dermoscopy. The commonest change recorded in our study was dilated capillaries in 21 (70%) patients, followed by capillary dropouts in 17 (56.7%) patients and avascular areas in 16 (53.3%) patients. Of 17 patients presenting with sclerodactyly, active, early and late patterns were seen in 7 (41.2%), 2 (11.8%) and 7 (41.2%) patients, respectively. Out of 13 patients with respiratory involvement, active, early and late patterns were seen in 1, 1 and 7 (53.8%) patients, respectively (P value = 0.004). Limitations: Owing to lesser number of patients in our study, it is difficult to draw conclusive recommendations, and more studies with a larger sample size are required. Conclusion: Dermoscopy is a valuable tool not only to diagnose collagen vascular disorders but also for prognostication by correlating with systemic involvement.

RESUMO

Objective: The main objective of this study is to improve the classification performance of melanoma using deep learning based automatic skin lesion segmentation. It can be assist medical experts on early diagnosis of melanoma on dermoscopy images. Methods: First A Convolutional Neural Network (CNN) based U-net algorithm is used for segmentation process. Then extract color, texture and shape features from the segmented image using Local Binary Pattern ( LBP), Edge Histogram (EH), Histogram of Oriented Gradients (HOG) and Gabor method. Finally all the features extracted from these methods were fed into the Support Vector Machine (SVM), Random Forest (RF), K-Nearest Neighbor (KNN) and Naïve Bayes (NB) classifiers to diagnose the skin image which is either melanoma or benign lesions. Results: Experimental results show the effectiveness of the proposed method. The Dice co-efficiency value of 77.5% is achieved for image segmentation and SVM classifier produced 85.19% of accuracy. Conclusion: In deep learning environment, U-Net segmentation algorithm is found to be the best method for segmentation and it helps to improve the classification performance.

RESUMO

BACKGROUND: Skin cancer (SC), especially melanoma, is a growing public health burden. Experimental studies have indicated a potential diagnostic role for deep learning (DL) algorithms in identifying SC at varying sensitivities. Previously, it was demonstrated that diagnostics by dermoscopy are improved by applying an additional sonification (data to sound waves conversion) layer on DL algorithms. The aim of the study was to determine the impact of image quality on accuracy of diagnosis by sonification employing a rudimentary skin magnifier with polarized light (SMP). METHODS: Dermoscopy images acquired by SMP were processed by a first deep learning algorithm and sonified. Audio output was further analyzed by a different secondary DL. Study criteria outcomes of SMP were specificity and sensitivity, which were further processed by a F2-score, i.e. applying a twice extra weight to sensitivity over positive predictive values. FINDINGS: Patients (n = 73) fulfilling inclusion criteria were referred to biopsy. SMP analysis metrics resulted in a receiver operator characteristic curve AUC's of 0.814 (95% CI, 0.798-0.831). SMP achieved a F2-score sensitivity of 91.7%, specificity of 41.8% and positive predictive value of 57.3%. Diagnosing the same set of patients' lesions by an advanced dermoscope resulted in a F2-score sensitivity of 89.5%, specificity of 57.8% and a positive predictive value of 59.9% (P=NS). INTERPRETATION: DL processing of dermoscopic images followed by sonification results in an accurate diagnostic output for SMP, implying that the quality of the dermoscope is not the major factor influencing DL diagnosis of skin cancer. Present system might assist all healthcare providers as a feasible computer-assisted detection system. FUND: Bostel Technologies. Trial Registration clinicaltrials.gov Identifier: NCT03362138.

RESUMO

BACKGROUND: Videodermatoscopy (VD) is a useful device for supporting dermatologists in the distinction between benign and malignant lesions. However, only few patients have access to VD in daily practice. OBJECTIVES: To investigate patient attitudes towards VD. METHOD: A cross-sectional study was conducted between May and June 2018. Patients were asked to complete a self-administered questionnaire on the popularity of VD. Descriptive analysis was performed including contingency tables and χ2 tests to investigate associations between sociodemographic data and the popularity of VD. RESULTS: A total of 61.2% (123/201) of the patients had not heard of VD at the time of assessment or were unsure. Of the 38.8% of patients (78/201) who already knew of VD, 64.1% (50/78) reported that they had already been investigated by VD; 57.5% (111/193) were willing to pay an extra fee for VD. A high level of education and private insurance status had a statistically significant association with the popularity of VD (p = 0.036 and p = 0.026, respectively). CONCLUSIONS: There was a strong information deficit, especially in patients with lower education and statutory health insurance. Nevertheless, the willingness to pay an extra fee for a VD-assisted skin examination was high. Dermatologists should actively offer and inform their patients about VD when performing skin cancer screening.
