Atypical cellular blue nevus or malignant blue nevus?

An. bras. dermatol; 92 (1), 2017
Abstract: Blue nevus is a benign melanocytic lesion whose most frequent variants are dendritic (common) blue nevus and cellular blue nevus. Atypical cellular blue nevus presents an intermediate histopathology between the typical and a rare variant of malignant blue nevus/melanoma arising in a cellular bl...

Initial basal cell carcinomas diagnosed in the National Campaign for Skin Cancer Prevention are smaller than those identified by the conventional medical referral system

An. bras. dermatol; 92 (1), 2017
Abstract: BACKGROUND: Basal cell carcinoma is the malignant tumor most often diagnosed in the National Campaign for Skin Cancer Prevention (NCSCP). Little is known about the profile of these lesions compared to the profile of lesions diagnosed by conventional routes of public dermatological care. OBJEC...

Giant cell tumor of the tendon sheath: a rare periungual location simulating myxoid cyst

An. bras. dermatol; 92 (1), 2017
ABSTRACT Giant cell tumor of the tendon sheath is a benign soft tissue tumor most frequent between the third and fifth decades of life. It can mimic and make differential diagnoses with several hand tumors. Definitive diagnosis and the treatment of choice are reached with complete resection and histopath...

Hemosiderotic dermatofibroma

An. bras. dermatol; 92 (1), 2017
Abstract: We report a rare clinical case of hemosiderotic dermatofibroma in a 36-year-old female patient. The main dermatoscopic finding was represented by homogeneous blue-gray pigmentation. The aim of this report is to demonstrate the rarity of the lesion and the dermatoscopic importance it assumes by ...

Which features of advanced head and neck basal cell carcinoma are associated with perineural invasion?

Abstract Introduction Perineural invasion is a unique route for tumor dissemination. In basal cell carcinomas, the incidence is low, but increases in advanced cases. Its importance is recognized but not fully understood. Objective To compare head and neck basal cell carcinomas with and without perineur...

Targeting personalized medicine in a non-Hodgkin lymphoma patient with 18F-FDG and 18F-choline PET/CT

Summary Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluordeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 (18F-FDG) has been used to evaluate staging, therapy response...

Two novel Co(II) complexes with two different Schiff bases: inhibiting growth of human skin cancer cells

Braz. j. med. biol. res; 50 (7), 2017
Using two flexible Schiff bases, H2L1 and H2L2, two new cobalt II (Co(II))-coordination compounds, namely, Py3CoL1 (1) and Py3CoL2 (2) (Py=pyridine, L1=3,5-ClC6H2(O)C=NC6H3(O)-4-NO2, L2=3,5-BrC6H2(O)C=NC6H3(O)-4-NO2) have been synthesized under solvothermal conditions. Single crystal X-ray structural ana...

Epigenetic signature of differentially methylated genes in cutaneous melanoma

Appl. cancer res; 37 (), 2017
Background: Cutaneous melanoma (CM) is the most aggressive subtype of skin cancer, with increasing incidence over the past several decades. DNA methylation is a key element of several biological processes such as genomic imprinting, cell differentiation and senescence, and deregulation of this mechanism ...

Relación entre ganglio centinela positivo y el espesor de Breslow en pacientes con melanoma cutáneo primario

Rev. Nac. (Itauguá); 9 (1), 2017
Introducción: es sabido que el pronóstico del melanoma cutáneo depende, entre otros factores, de la existencia de diseminación linfática a ganglios. La biopsia del ganglio centinela busca identificar metástasis ganglionares subclínicas. Objetivo: el presente estudio tuvo por objetivo analizar l...
