Dear VCGP group, My name is Igor R. Santos. I am a Brazilian master's student in veterinary pathology at the Department of Veterinary Pathology of the Universidade Federal of Rio Grande do Sul, Brazil. I am writing to propose relevant guidelines topics and to express my willingness to help if possible. Currently, I'm working on a research project related to histological and immunohistochemical findings of feline pulmonary carcinomas. Your guidelines of the mitotic count, mitotic figure morphology, necrosis, and lymphovascular invasion were fundamental for the assessment. However, scores for evaluating the histological assessment of desmoplasia and immunoreactivity vary in previous studies, and it is sometimes challenging to select the ideal one. Therefore, I was wondering about the possibility of an approach to these topics in future guidelines. I want to express my appreciation for your work because the guidelines have been very beneficial for us. Thank you all for the initiative! I am looking forward to the pleomorphism, lymph node assessment, and metastasis guidelines. I feel inspired by the work you have been developing. Therefore, I am very interested in participating in the group as a volunteer and helping in any way I can. Thank you for your time. Best regards, -- *Igor R.
