Fibrosarcoma subcutáneo, Crotalus morulus, Nuevo Leon

Resumen

Un espécimen macho de cascabel de la montaña (Crotalus morulus) con más de 20 años en cautiverio se presenta a consulta por la presencia de una masa de aspecto tumoral en la parte media dorsal del cuerpo. El único signo clínico que presentó fue anorexia, ya que no mostraba cambios significativos en su actividad ni condición corporal. Se llevó a cabo la cirugía de recisión tumoral como tratamiento de elección y la masa pudo ser retirada completamente en una pieza y enviada para su estudio histopatológico. Lamentablemente, el paciente falleció 16 días después de la cirugía. No se realizó necropsia. Al estudio de laboratorio con las tinciones de hematoxilina y eosina así como tinción tricrómica de Masson se encontró anisocitosis y anisocariosis con células fusiformes y poligonales en fascículos irregulares, entremezcladas con fibras de colágena; el índice mitótico era marcado, con 2 a 3 nucléolos por núcleo, y fue notable la presencia de numerosas mitosis atípicas. También había presencia de numerosos vasos sanguíneos y escasas células inflamatorias. Se diagnosticó fibrosarcoma subcutáneo con alto riesgo de metástasis. Mediante el presente reporte de caso, se pretende aportar información que permita el estudio de los procesos oncológicos en ofidios en cautiverio.

David Lazcano-Villarreal, Universidad Autónoma de Nuevo León

David Lazcano is a herpetologist who earned a bachelor’s degree in chemical science in 1980, and a bachelor’s degree in biology in 1982. In 1999 he earned a master’s degree in wildlife management, and later a doctoral degree in biological sciences with a specialty in wildlife management (2005), all gained from the Facultad de Ciencias Biológicas of the Universidad Autónoma de Nuevo León. Currently, he is a full-time professor at the same institution, where he teaches courses in animal behavior, biogeography, biology of chordates, and wildlife management. He is also the head of Laboratorio de Herpetología and Coordinación de Intercambio Académico de la Facultad de Ciencias Biológicas at UANL. Since 1979, he has been teaching and providing assistance in both undergraduate and graduate programs. His research interests include the study of the herpetofaunal diversity of northeastern Mexico, as well as the ecology, herpetology, biology of the chordates, biogeography, animal behavior, and population maintenance techniques of montane herpetofauna. In addition, the species Gerrhonotus lazcanoi has been named in his honor.
