Ki67 density maps in canine tumors

This dataset contains aimed to evaluate the classification of the spatial distribution of the most proliferative areas in selected canine tumour types, using Ki67 immunohistochemistry. Tumour types analysed included melanomas, cutaneous mast cell tumours, canine mammary carcinomas and soft tissue sarcomas. Using im-age analysis, Ki67 density maps were generated from digital slides and classified according to their distribution pattern (focal/multifocal or diffuse) and location within the tumour (central, peripheral or scattered).
