- ItemSomente MetadadadosAvaliação dos padrões dermatoscópicos das lesões melanocíticas nas áreas de transição entre a pele glabra e não-glabra(Universidade Federal de São Paulo (UNIFESP), 2019-12-18) Junco, Fernanda Braga [UNIFESP]; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: To evaluate the dermatoscopic patterns of melanocytic lesions in the transition zone between glabrous and non-glabrous skin. Methods: Retrospective study in which 82 cases of melanocytic lesions in the transition zone between glabrous and non-glabrous skin were selected, all of them evaluated in the dermatoscopy outpatient clinic of the Federal University of São Paulo - São Paulo School of Medicine (Universidade Federal de São Paulo - Escola Paulista de Medicina), between 1999 to 2018. The dermatoscopic pattern of each lesion was evaluated by two dermatologists with experience in dermatoscopy. The dermatoscopic pattern, the anatomical location in the palmoplantar region and the location on the Wallace line were studied. All variables were correlated with the chi-square test. Results: 82 melanocytic lesions in the palmoplantar transition zone were studied, in which 77 cases were benign melanocytic lesions in the transition zone between glabrous and non-glabrous skin and five were melanomas. All dermatoscopic patterns were grouped into single patterns and combined patterns. The frequency of single dermatoscopic patterns, in descending order, was: parallel grooves (22/77), grid (9/77), fibrillar (7/77), net (5/77), pod (3/77), globular (2/77), parallel crests (2/77). 27 lesions presented combined patterns (27/77) that are described in descending order: reticulate/parallel grooves (10/77), grid/parallel grooves (7/77), fibrillar/globular (2/77), grid/reticulate (2/77), pod/parallel grooves (2/77), globular/homogeneous (2/77), globular/parallel grooves (1/77), homogeneous/parallel grooves (1/77) and parallel crests/multicomponent (1/77). An anatomopathological exam was done in 17 of all 77 benign melanocytic lesions. The results, in descending order, were: lentiginous compound melanocytic nevi (8/17), compound melanocytic nevi (2/17), junctional melanocytic nevi (2/17), lentiginous junctional melanocytic nevi (2/17), lentiginous melanocytic nevus (2/17) and lentigo simplex (1/17). The other 60 cases that were not excised presented benign dermoscopic features and are in dermatoscopic follow-up. We analyzed the frequency of single and combined dermatoscopic patterns regarding the different locations of the palmoplantar region: fingers (14/77), toes (17/77), heel (19/77), lateral of the feet (14/77) and medial of the feet (13/77). We also evaluated the dermatoscopic patterns distribution in respect to the Wallace line: superior, exactly in the line’s center and inferior. There was no correlation between the combined dermatoscopic pattern and its palmoplantar anatomical location or the location of the transition nevus in the Wallace line. There was no correlation between the dermoscopic patterns and individuals age. Conclusions: The dermatoscopic pattern that was more present in the transition one between the glabrous and non-glabrous skin is the parallel grooves, followed by the reticular transition/parallel grooves pattern. The combined pattern was found in 35% of all lesions (27/77) and the transition dermatoscopic pattern was found in 12 of these combined pattern lesions (12/27). There was no correlation between the single and combined patterns with the anatomical location of the lesions in the different plantar areas or the location on the Wallace line.
- ItemAcesso aberto (Open Access)A case of pigmented Bowen's disease(Soc Brasileira Dermatologia, 2017) Vivan, Marcia Maria [UNIFESP]; Hirata, Sergio Henrique [UNIFESP]; Nascimento, Liliane Santos do [UNIFESP]; Enokihara, Mílvia Maria Simões e Silva [UNIFESP]Pigmented Bowen's disease is a rare subtype of Bowen's disease. Clinically it presents as a slow-growing, well-defined, hyperpigmented plaque, and should be included as a differential diagnosis of other pigmented lesions. The authors describe a challenging case of pigmented Bowen's disease with non-diagnostic dermscopy findings.
- ItemAcesso aberto (Open Access)Case report: dermoscopic and histological aspects of skin graft and perigraft hyperpigmentation in acral location(Sociedade Brasileira de Dermatologia, 2014-06-01) Tuma, Bruna; Yamada, Sergio; Medeiros, Rodrigo Almeida De; Nascimento, Mauricio Mendonca Do; Hirata, Sergio Henrique [UNIFESP]; Universidade Estadual de Londrina; Universidade Federal de São Paulo (UNIFESP); aff03Little is known about the use of dermoscopy in skin grafting. We describe the case of a patient with skin grafting and surrounding pigmentation on acral region. The dermoscopic findings were similar to those of benign acral lesions (lattice-like pattern) and reactive pigmentations (fine striae). Histopathology revealed pigment leakage and increased number of melanocytes. It is believed that this phenomenon occured as the result of an inflammatory stimulus.
- ItemAcesso aberto (Open Access)Consensus on melanonychia nail plate dermoscopy(Sociedade Brasileira de Dermatologia, 2013-04-01) Chiacchio, Nilton Di; Farias, Débora Cadore De; Piraccini, Bianca Maria; Hirata, Sergio Henrique [UNIFESP]; Richert, Bertrand; Zaiac, Martin; Daniel, Ralph; Fanti, Pier Alessandro; Andre, Josette; Ruben, Beth S; Fleckman, Philip; Rich, Phoebe; Haneke, Eckart; Chang, Patricia; Cherit, Judith Dominguez; Scher, Richard; Tosti, Antonella; Hospital do Servidor Público Municipal de São Paulo Dermatology Clinic; Federal University of Santa Catarina University Hospital, Dermatology Clinic,; University of Bologna Department of Dermatology; Universidade Federal de São Paulo (UNIFESP); University of Liège Dermatology Department; Greater Miami Skin and Laser Center; University of Mississippi Department of Dermatology; University of Alabama Department of Dermatology; Université Libre de Bruxelles Department of Dermatology; University of California Departments of Dermatology and Pathology; University of Washington Division of Dermatology,; University of Oregon Department of Dermatology; University of Berne Dermatology Practice, Freiburg (Germany) and Dermatology Department; Hospital Angeles Department of Dermatology; Hospital General Dr Manuel Gea González Department of Dermatology; University of North Carolina Department of Dermatology; University of Miami Miller Medical School Department of Dermatology,This statement, focused on melanonychia and nail plate dermoscopy, is intended to guide medical professionals working with melanonychia and to assist choosing appropriate management for melanonychia patients. The International Study Group on Melanonychia was founded in 2007 and currently has 30 members, including nail experts and dermatopathologists with special expertise in nails. The need for common definitions of nail plate dermoscopy was addressed during the Second Meeting of this Group held in February 2008. Prior to this meeting and to date (2010) there have been no evidence-based guidelines on the use of dermoscopy in the management of nail pigmentation.
- ItemAcesso aberto (Open Access)Dermoscopic findings in female androgenetic alopecia(Sociedade Brasileira de Dermatologia, 2012-10-01) Ramos, Lya Duarte; Santili, Maria Cândida Nahás; Bezerra, Fabiane Castilho; Ruiz, Maria De Fátima Maklouf Amorim [UNIFESP]; Petri, Valeria [UNIFESP]; Patriarca, Marisa Teresinha [UNIFESP]; Secretaria de Saúde do Estado de São Paulo Hospital Ipiranga; Universidade Federal de São Paulo (UNIFESP); Secretaria de Saúde do Estado de São Paulo Hospital Ipiranga Dermatology DepartmentBACKGROUND: Androgenetic alopecia is the most common form of hair loss. It is a clinical entity of relevant interest and presents a significant psychosocial impact as it undermines self-esteem and quality of life in female patients due to the importance of the hair for people's facial balance. OBJECTIVE: The purpose of the present study is to evaluate dermoscopic signs in women clinically diagnosed with androgenetic alopecia. METHOD: Observational study with 34 women between 17 and 68 years old who were diagnosed with androgenetic alopecia. All of them underwent photographic sessions with a 10x magnification dermoscope and a digital camera zoom set to 20x magnification and 40x magnification on the scalp frontal midline. RESULTS: All patients showed miniaturization. A peripilar brown halo was found in 22 patients, honeycomb-like scalp pigmentation was found in 14 and yellow dots in only 1 patient. Recent studies show dermoscopy as the new tool for diagnosis assistance and treatment follow up in scalp disorders. Our study used an ordinary dermoscope and we evaluated several findings reported in the literature with significant clarity and easiness. CONCLUSION: The dermoscope, which is used by dermatologists on a daily basis, is an excellent tool to assist in early diagnosis and assessment of therapeutic response in androgenetic alopecia.
- ItemAcesso aberto (Open Access)Dermoscopy of Bowen's disease: pigmented variant on the penis(Sociedade Brasileira de Dermatologia, 2012-06-01) Ishioka, Priscila [UNIFESP]; Yamada, Sérgio [UNIFESP]; Michalany, Nilceo Schwery [UNIFESP]; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Pigmented Bowen's disease (PBD) is a variant of squamous cell carcinoma in situ and represents less than 2% of cases of Bowen's disease. It is characterized by a sharply demarcated, pigmented plaque with a scaly or crusted surface on intertriginous and genital areas. The authors describe a case of PBD on the penis and analyze the dermoscopic aspects of this type of lesion.
- ItemAcesso aberto (Open Access)Diagnóstico do tumor glômico pela dermatoscopia do leito e da matriz ungueal(Sociedade Brasileira de Dermatologia, 2010-04-01) Maehara, Laura de Sena Nogueira [UNIFESP]; Ohe, Eugenia Maria Damasio [UNIFESP]; Enokihara, Mauro Yoshiaki [UNIFESP]; Michalany, Nilceo Schwery [UNIFESP]; Yamada, Sergio [UNIFESP]; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Surgery is the best treatment for glomus tumors. Sometimes this can be a challenging procedure because, despite being a well-defined tumor, its visualization can be difficult. The use of nail bed and matrix dermoscopy facilitates the diagnosis and aids in the localization and demarcation of the tumor. It is a simple and low-cost procedure that does not involve additional risks to the patient who will undergo surgery.
- ItemAcesso aberto (Open Access)Dysplastic nevus associated with seborrheic keratosis(Sociedade Brasileira de Dermatologia, 2014-01-01) Botelho, Luciane Francisca Fernandes; Michalany, Nilceo Schwery; Enokihara, Milvia Maria Simoes E Silva; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Seborrheic keratosis is a common skin lesion which may coincidentally be associated melanocytic nevi. The authors describe a case of dysplastic nevus associated with seborrheic keratosis and discuss the clinical, dermoscopic, and histological findings of this association. They also discuss the association between seborrheic keratosis and other benign and malignant tumours.
- ItemAcesso aberto (Open Access)Granuloma faciale: a rare disease from a dermoscopy perspective(Sociedade Brasileira de Dermatologia, 2013-12-01) Teixeira, Danilo Augusto; Estrozi, Bruna; Ianhez, Mayra; Federal University of Goiás Department of Dermatology; Pathologist at the Pathology Consulting Service - Botucatu (SP); Universidade Federal de São Paulo (UNIFESP); Federal University of GoiásThe granuloma faciale is a rare and benign skin disease of unknown etiology, characterized by chronic leukocitoclastic vasculitis. It is characterized by skin lesions predominantly facial whose course is chronic and slowly progressive. The diagnosis is based on clinical features, histopathology and, more recently, in dermoscopy. We describe the case of a male patient, 40 years old, with a sarcoid lesion on the malar site, whose histopathological examination revealed a mixed inflammatory infiltrate with presence of Grenz zone. Dermoscopy revealed a pink background with white striations. The definitive diagnosis is made by histopathologic evaluation, and dermatoscopy can be helpful. It is known to be resistant to therapy, oral medications, intralesional and surgical procedures are options.
- ItemSomente MetadadadosPolarized dermoscopy of mammary Paget disease(Soc Brasileira Dermatologia, 2013-03-01) Crignis, Giselly Silva Neto de; Abreu, Luciana de; Bucard, Alice Mota; Barcaui, Carlos Baptista [UNIFESP]; Char Hosp Rio Janeiro; IDPRDA SCMRJ; Fed Hosp Bonsucesso; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)Mammary Paget's disease is a rare intraepithelial adenocarcinoma, located on the nipple/areola complex, highly associated with breast cancer. Although the international literature emphasizes the dermatoscopic pattern of mammary Paget's disease pigmented variant, the authors describe the dermoscopic findings of classical Paget's disease and demonstrate the presence of chrysalis-like structures, criteria recently described in the literature and not yet reported in Paget's disease.
- ItemAcesso aberto (Open Access)Polypoid melanoma and superficial spreading melanoma different subtypes in the same lesion(Sociedade Brasileira de Dermatologia, 2014-07-01) Hikawa, Renato Shintani [UNIFESP]; Kanehisa, Eliza Sayuri; Enokihara, Mílvia Maria Simões e Silva; Enokihara, Mauro Yoshiaki; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Melanoma is a malignant melanocytic neoplasm with high mortality rate, and steadily and universally increasing incidence rates. Polypoid melanoma is considered an exophytic variant of the nodular subtype. The incidence of polypoid melanoma is extremely variable, most likely because of the different criteria used for its characterization. We presented a rare case of polypoid melanoma and superficial spreading melanoma in the same lesion.
- ItemAcesso aberto (Open Access)Tungiasis under dermoscopy: in vivo and ex vivo examination of the cutaneous infestation due to Tunga penetrans(Sociedade Brasileira de Dermatologia, 2013-08-01) Criado, Paulo Ricardo; Landman, Gilles [UNIFESP]; Reis, Vitor Manoel Silva Dos; Belda Junior, Walter; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP); Universidade Estadual de Campinas (UNICAMP)The female flea Tunga penetrans is responsible for a cutaneous parasitosis known as Tungiasis. We report the clinical case of a 12 year-old Caucasian boy who sought treatment in a dermatological private office due to a painful lesion in the plantar area and whose dermoscopic examination, without skin contact, allowed the visualization of parasite's movement inside the skin. The diagnosis of tungiasis is clinical, but it can be aided by in vivo and ex vivo dermoscopic examination of the lesion.
