289:. Some punch biopsies are shaped like an ellipse, although one can accomplish the same desired shape with a standard scalpel. The 1 mm and 1.5 mm punch are ideal for locations where cosmetic appearance is difficult to accomplish with the shave method. Minimal bleeding is noted with the 1 mm punch, and often the wound is left to heal without stitching for the smaller punch biopsies. The disadvantage of the 1 mm punch is that the tissue obtained is almost impossible to see at times due to small size, and the 1.5 mm biopsy is preferred in most cases. The common punch size used to diagnose most inflammatory skin conditions is the 3.5 or 4 mm punch.
528:. It is not infrequent for two, three or more biopsies to be performed by different doctors for the same skin condition, before the correct diagnosis is made on the final biopsy. The method, depth, and quality of clinical data will all affect the yield of a skin biopsy. For this reason, doctors specializing in skin diseases are invaluable in the diagnosis of skin cancers and difficult skin diseases. Specific stains (PAS, DIF, etc.), and certain type of sectioning (vertical and horizontal) are often requested by an astute physician to make sure that the pathologist will have all the necessary information to make a good histological diagnosis.

the normal skin (to show the interface between normal and abnormal skin). Incisional biopsy often yield better diagnosis for deep pannicular skin diseases and more subcutaneous tissue can be obtained than a punch biopsy. Long and thin deep incisional biopsy are excellent on the lower extremities as they allow a large amount of tissue to be harvested with minimal tension on the surgical wound. Advantage of the incisional biopsy over the punch method is that hemostasis can be done more easily due to better visualization. Dog ear defects are rarely seen in incisional biopsies with length at least twice as long as the width.
486:"; many "shave" excisions do not penetrate the dermis or subcutaneous fat enough to include the entire melanocytic lesion, and residual melanocytes regrow into the scar. The combination of scarring, inflammation, blood vessels, and atypical pigmented streaks seen in these recurrent nevi may result in the dermatoscopic appearance of a melanoma. When a second physician later examines the patient, he or she has no choice but to recommend re-excision of the scar. If one does not have access to the original pathology report, it is impossible to distinguish a recurring nevus from a severely

Many prefer the small punch method for initial diagnostic value before resorting to the excisional biopsy. An initial small punch biopsy of a melanoma might say "severe cellular atypia, recommend wider excision". At this point, the clinician can be confident that an excisional biopsy can be performed without risking committing a "

as better than standard excision and less time-consuming. The added economic benefit is that many surgeons bill the procedure as an excision, rather than a shave biopsy.

diagnosis. An example would be a rapidly growing dome shaped tumor of the sun exposed skin.

A saucerization biopsy is also known as "scoop", "scallop", or "shave" excisional biopsy, or "shave" excision. A trend has occurred in dermatology over the last 10 years with the advocacy of a deep shave excision of a pigmented lesion. An author published the result of this method and advocated it
