(BQ) Part 2 book "Mohs surgery and histopathology: Beyond the fundamentals" presents the following contents: Introduction to laboratory techniques, microanatomy and neoplastic disease, pecial techniques and stains. | CHAPTER 10 Mohs Mapping Howard K. Steinman MOHS SURGERY requires meticulous recording of wound and specimen details and pathology findings on a diagrammatic Mohs map. The map is vital as a safeguard against orientation errors and for correlating findings from pathology slides to the wound. The map is also a component of the operative report the pathology report and a medicolegal document. Properly completed it will accurately depict what was performed and why. Mohs maps may be drawn on preprinted anatomic diagrams blank paper sheets or photographs. All surgery stages may be depicted on one map sheet or each stage may have its own. Map notation occurs in three settings Table . Before surgery maps must contain patient demographic data the surgery date and the tumor type and anatomic location. Before tissue processing maps must accurately depict 1 specimen shape and orientation 2 reference marks 3 patterns of any specimen subdivision into smaller tissue sections 4 section numbering and 5 the tissue inking patterns. After slide interpretation maps must precisely depict the location of tumor foci and other relevant findings. These findings may include incomplete surgical margins foci of dense inflammation and scar tissue unrelated benign tumors . nevi or keratoses and any orientation errors. MAP SHAPES The map depicts the shape of the surgical margin. The wound usually expands after the excision while the specimen margin contracts often asymmetrically Figure . The relevant shape for map drawing is the wound base where residual tumor will be located. Map shapes may be precise or representational depictions of the wound. Drawing the diagram larger than the wound permits more precise correlation of slide findings to the wound.
