High proliferative activity and peripheral invasion indicate malignancy in canine sebaceous gland tumors; the term 'epithelioma' should be updated for clarity.
research Acquired Localized Longitudinal Pachyonychia and Onychomatrical Tumors: A Comparative Study to Onychomatricomas (5 Cases) and Onychocytic Matricomas (4 Cases)
Larger nail cavity sizes suggest benign tumors, while smaller ones may need further biopsy to rule out cancer.
research Conventional histopathology and new technologies in cutaneous mucinoses: Old diagnostic criteria and new therapeutic perspectives
New technologies show potential for better understanding and treating skin conditions with abnormal mucin, but more research is needed for clinical use.
