Intraoral atypical lentiginous melanocytic lesion in a pediatric patient
(2021-01-01)
We present a rare case of intraoral atypical lentiginous melanocytic lesion affecting a pediatric patient, in which the diagnosis of lentiginous junctional melanocytic nevus with cytologic atypia was favored. The main ...
Visceral colouration of Eupemphix nattereri (Anura: Leiuperidae): effects of NDP-α-melanocyte stimulating hormone
(2013-08-02)
Amphibians have melanin-containing cells in visceral organs that are similar to pigmentary cells from the epidermis. Both of them are derived from the ectodermal neural crest. Epidermal cells respond to α-melanocyte ...

Immunohistochemical expression of cyclooxygenase-2 (COX-2) in oral nevi and melanoma
(Wiley, 2015)
BACKGROUND: Cyclooxygenase-2 (COX-2) catalyses the conversion of arachidonic acid to prostaglandin, and its overexpression has been demonstrated in different malignant tumors, including cutaneous melanoma. However, no data ...
Melanocytes in the testes of Eupemphix nattereri (Anura, Leiuperidae): Histological, stereological, and ultrastructural aspects
(Wiley-Blackwell, 2007-07-01)
Ectothermic vertebrates have a well-developed system of melanin-containing cells, which localize in several organs and tissues and compose an extracutaneous pigmentary system. This research aimed at characterizing histological ...
Sex hormones change visceral pigmentation in Eupemphix nattereri (Anura): effects in testicular melanocytes and hepatic melanomacrophages
(Brill Academic Publishers, 2015-01-01)
Melanomacrophages and melanocytes are able to modify pigment intensity on the body surface as a response to temperature change, hibernation, hypoxia, infection, oxidative stress and exogenous use of hormones. This study ...
Expression of fatty acid synthase (FASN) in oral nevi and melanoma
(Wiley, 2011)
The aim of this study was to determine the expression of fatty acid synthase (FASN) in oral nevi and melanomas, comparing the results with correspondent cutaneous lesions. Materials and Methods: Expression of FASN was ...
