Summary: | The objective of this note is to describe a case of exuberant scarring formation, with keloid characteristics and pseudo-tumoral configuration in a male Black caiman (Melanosuchus niger), with an estimated age of 60 years, belonging to the Zoobotanical Park at the Emílio Goeldi Museum, located in Belém, Pará, Brazil. The alteration appeared on the right posterior limb involving two distal phalanges of the lateral digit and measured 12.4cm at the greatest width. The keloid tissue was surgically removed and samples were processed and analyzed histopathologically, revealing growth made up of fibrous connective tissue with the habitual morphology, which was structurally mature in the more central areas.
O objetivo do presente relato é descrever um caso de formação cicatricial exuberante, característica de queloide e configuração pseudo-tumoral em um jacaré-açu (Melanosuchus niger), macho, com idade estimada de 60 anos, pertencente ao Parque Zoobotânico do Museu Emílio Goeldi, situado em Belém, Pará, Brasil. A alteração manifestou-se no membro posterior direito, envolvendo as duas falanges distais do dedo lateral e mediu 12,4cm na maior largura. A neoformação foi removida cirurgicamente e amostras foram processadas e analisadas por histopatologia, que revelou crescimento constituído por tecido conjuntivo fibroso de morfologia habitual, estando estruturalmente maduro nas áreas mais centrais. |
