Information of the past fellows
Dr. Jonathan P. Rivera
Department of Laboratories, Philippine General Hospital, Manila, Philippines (Head and neck/thyroid pathology and cytopathology fellow, June 2023 – May 2024)

During his fellowship training, Dr. Rivera reviewed routine and referral histopathology and cytopathology cases of the head and neck/thyroid, under the guidance of the program directors, Dr. Jen-Fan Hang and Dr. Ying-Ju Kuo. This led to a fruitful discussion on morphology, pertinent differential diagnosis, and relevant ancillary tests that needed to be performed on the cases. He also helped on drafting the consultation reports in selected referral cases to aptly apply what he had learned. To further his expertise in the field, he was given access to whole slide images of rare and difficult cases of the head and neck/thyroid. In addition, Dr. Rivera actively participated in daily online conferences led by attending pathologists in various subspecialties, observed the grossing of surgical pathology specimens, and was allowed to participate in the multidisciplinary conferences held in the hospital. Furthermore, he collaborated on two projects, one invited review and one research, intended for international publication and served as the primary author for both. As a highlight of his fellowship training, he presented his research on the Endocrine Pathology platform at the annual meeting of the United States and Canadian Academy of Pathology (USCAP) held in March 23-28, 2024 in Baltimore, Maryland. This study has been subsequently accepted by the prestigious scientific journal, American Journal of Surgical Pathology.

Dr. Pocholo D. Santos
Department of Pathology and Laboratories, Makati Medical Center, Makati, Philippines (Cytopathology fellow, January – July 2024)

My rotation at Taipei Veterans General Hospital (TVGH) was an immensely rewarding experience that strengthened my diagnostic and research foundation in cytopathology. The department handled a wide range of cases, from routine samples to rare and complex entities, offering exceptional learning opportunities. I was actively involved in the daily sign-out of cases and was provided my own cubicle, microscope, and computer, which allowed me to work independently while learning from expert mentors. I also had full access to their digital archives, resources, and software systems, which greatly supported my research. During my stay, I was exposed to different cytology techniques and immunocytochemistry, further enhancing my technical understanding. What stood out most was their strong focus on cytomorphology, the very basics that remain the cornerstone of accurate diagnosis. This emphasis refined my diagnostic precision and appreciation for cellular detail. I was also given the opportunity to present a research paper at an international conference in Florence, Italy, an experience made possible through their unwavering support and guidance. Even after completing my rotation, our academic communication continues, a testament to TVGH’s mentorship and commitment to excellence in cytopathology.
