The dataset consists of 99 H&E-stained whole slide skin images (WSI) - 49 abnormal and 50 normal cases. All significant abnormal findings identified are outlined and categorized into 13 types such as actinic keratosis, basal cell carcinoma and dermatofibroma. Other tissue components, such as epidermis, adnexal structures, as well as the surgical margin are delineated to create a complete histological map. In total, 16741 separate annotations have been made to segment the different tissue structures and link them to ontological information.

Annotation

One physician was responsible for the manual annotations controlled by a second pathologist. Accurate annotations were made over the whole tissues. 16741 separate annotations were made.

The following findings were annotated in the abnormal cases: actinic keratosis, basal cell carcinoma, dermatofibroma, dysplastic nevus, intradermal nevus, keratoachantoma, lentigo malignant melanoma, malignant melanoma, malignant melanoma in situ, scar, seborrheic keratosis, squamous cell carcinoma and squamous cell carcinoma in situ. Other areas annotated: abnormal, acanthosis, artifacts, dermis, epidermis, fibrosis, fibrin body, granuloma, inflammation, inflammatory edema, normal, perichondrium, reactive cellular changes, skin appendage structure, surgical margins, structure of cartilage of auditory canal, subcutaneous fatty tissue, subcutaneous tissue, surgical margins and from which body part the skin was excised.

In the normal skin cases were following structures chosen to be annotated: artifact, dermis, epidermis, normal skin, perichondrium, skin and subcutaneous structure, skin appendage structure, skin structure, structure of cartilage of auditory canal, subcutaneous fatty tissue, subcutaneous tissue and surgical margins.

Pixel position scaling

Coordinates given are relative to the image width. To get the correct pixel position, X coordinates (and Y coordinates!) should therefore be multiplied with the image width.
