Residents in the Department of Pathology presented their outstanding scholarly work at the 2025 American Society of Dermatopathology (ASDP) Annual Meeting held Nov. 6-9 in Baltimore.

Katrina Jiang, M.D., a first-year resident, delivered an oral presentation titled “Two Cases of Electron Microscopy-Proven SMARCA4-Deficient Undifferentiated Large Cell Neuroendocrine Carcinoma Presenting as Subcutaneous Masses.”

Jiang also presented two posters at the conference: “Desmoplastic Melanoma with Loss of SOX10 and S100 Expression and p63 Positivity: A Rare Diagnostic Pitfall” and “An Unusual Presentation of Delayed Psoriasis Years After PD-1 Checkpoint Inhibitor Discontinuation.”

Ardenne Martin, M.D., a second-year resident, gave an oral presentation titled “Protein Kinase C Fused Melanocytoma with Sentinel Lymph Node Involvement in a Young Male.”

“These presentations are a testament to the department’s continued commitment to advancing diagnostic excellence, research innovation, and national academic engagement in dermatopathology,” said Guillermo A. Herrera, M.D., professor and chair of pathology. “Their contributions reflect the high level of scholarship and clinical rigor within our department and institution.”

Dermatopathologists are physicians who, after completing their training in either dermatology or pathology, pursued additional training in accredited programs for the interpretation of skin biopsies. These physicians integrate the clinical information with microscopic observations of the biopsy from the patient to provide diagnostic information to the treating physician.

The mission of the ASDP is to improve patient care, support member needs, and advance the field of dermatopathology through education, advocacy and innovation.
