Fig 1 Histopathological examination method of a punch biopsy specimen suspicious for basal cell carcinoma. Schematic overview of the histopathological examination process. The dimensions of the punch biopsy specimen might be smaller than depicted in this figure because of shrinkage after formalin fixation and histologic processing, embedding, and mounting. X: These sections are stained with hematoxylin-eosin and used for histopathological examination. In the initial sections it is unknown which slices are stained and examined.

Supplemental Fig 1 Detection of various basal cell carcinoma subtypes and adnexal extension in hematoxylin-eosin-stained sections. A, Superficial component in the initial section of punch biopsy specimen 24 (Supplemental Table II). B to E, In the additional sections of the same punch biopsy specimen (micro-) nodular and infiltrative subtypes are detected. F, Some lesions showed an adnexal extension (arrow).
