Melanonychia associated with subungual follicular inclusions: report of three c...
Câmara de Oliveira,Marina; Barcaui,Carlos Baptista; Barcaui,Elisa de Oliveira; Piñeiro-Maceira,JuanAbstract Melanonychia is the change in the coloration of the nail plate resulting from the deposition of melanin. Among its causes are melanocytic hyperplasia, melanocytic activation and nail melanoma. Subungual follicular inclusions are histological findings of unknown etiology, possibly related to trauma. We present three cases of melanonychia of different etiologies with subungual follicular inclusions, an a...
Profile of the use of dermoscopy among dermatologists in Brazil (2018),
Barcaui,Carlos Baptista; Miot,Helio AmanteAbstract Background: Dermoscopy increases the diagnostic accuracy in dermatology. The aspects related to training, usage profile, or perceptions of usefulness of dermoscopy among dermatologists in Brazil have not been described. Objectives: To evaluate the profile of the use of dermoscopy and the perception of the impact of the technique on clinical practice. Methods: The Brazilian Society of Dermatology invite...
Combined high-frequency and Doppler ultrasound in early diagnosis of atrophoder...
Barcaui,Elisa de Oliveira; Carvalho,Antonio Carlos Pires; Piñeiro-Maceira,Juan; Barcaui,Carlos BaptistaAbstract: Atrophoderma of Pasini and Pierini is a skin disorder affecting dermal collagen and is clinically characterized by well-defined plaques of depressed skin. Histopathological changes are subtle, and in most cases, the diagnosis requires a comparative study with healthy skin from the same anatomical site. High frequency ultrasound is a useful imaging method for diagnosis of atrophic skin changes. A case ...
Descriptive dermoscopy terminology in Portuguese language in Brazil: a reproduc...
Barcaui,Carlos Baptista; Bakos,Renato Marchiori; Paschoal,Francisco Macedo Camargo; Bittencourt,Flávia Vazquez; Gadens,Guilherme Augusto; Hirata,SérgioAbstract: Background: Dermoscopy is a noninvasive complementary diagnostic method largely used in dermatology. Feasibility, accuracy, and reproducibility are key elements for a diagnostic method to be useful, hence the importance of the terminology used to describe dermoscopic criteria. Objective: To evaluate the reproducibility of the English descriptive terminology proposed for dermoscopic criteria at the 3rd...
Multiple cutaneous melanomas associated with gastric and brain metastases
Grander,Lara Caroline; Cabral,Fernanda; Lisboa,Alice Paixão; Vale,Gabrielle; Barcaui,Carlos Baptista; Maceira,Juan Manuel PineiroAbstract The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronou...
High frequency ultrasound with color Doppler in dermatology
Barcaui,Elisa de Oliveira; Carvalho,Antonio Carlos Pires; Lopes,Flavia Paiva Proença Lobo; Piñeiro-Maceira,Juan; Barcaui,Carlos BaptistaAbstract: Ultrasonography is a method of imaging that classically is used in dermatology to study changes in the hypoderma, as nodules and infectious and inflammatory processes. The introduction of high frequency and resolution equipments enabled the observation of superficial structures, allowing differentiation between skin layers and providing details for the analysis of the skin and its appendages. This pap...
Lichen sclerosus associated with localized scleroderma: dermoscopy contribution
Nóbrega,Monisa Martins; Cabral,Fernanda; Corrêa,Mariana César; Barcaui,Carlos Baptista; Bressan,Aline Lopes; Gripp,Alexandre CarlosAbstract: Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color. The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen scler...
Contoured technique for lentigo maligna
Mateus,Monica Jidid; Tortelly,Violeta Duarte; Barcaui,Carlos Baptista; Jourdan,Carla Araujo; Simão,Tassiana; Maceira,Juan Manuel PiñeiroThe surgical approach to lentigo maligna is a challenge to dermatologists, given the difficulty of clinical delimitation of borders. We report here a case of a 69-year-old female patient presenting with brownish macules on her face, since 10 years ago, with histopathological diagnosis of lentigo maligna. The surgical management employed was excision of visible borders with the contoured technique and immediate ...
Collision of malignant neoplasms of the skin: basosquamous cell carcinoma assoc...
Medeiros,Paula Mota; Alves,Natália Ribeiro de Magalhães; Silva,Cássia Camarinha da; Faria,Paula Carolina Pessanha de; Barcaui,Carlos BaptistaAbstract Collision tumors are characterized by the coexistence of two cancers in the same anatomical site and its pathogenesis remains controversial. Although uncommon, the association of basal cell carcinoma and melanocytic nevus is the most common among combinations of skin tumors. Even rarer is the association of two malignant tumors. We report a case of tumor collision representing melanoma and basosquamous...
Study of the skin anatomy with high-frequency (22 MHz) ultrasonography and hist...
Barcaui,Elisa de Oliveira; Carvalho,Antonio Carlos Pires; Piñeiro-Maceira,Juan; Barcaui,Carlos Baptista; Moraes,HelenoAbstractThe present essay is aimed at getting the radiologist familiar with the basic histological skin structure, allowing for a better correlation with sonographic findings. A high-frequency (22 MHz) ultrasonography apparatus was utilized in the present study. The histological analysis was performed after the skin specimens fixation with formalin, inclusion in paraffin blocks and subsequent staining with hema...
