A punch biopsy is essentially an incisional biopsy, except it is round rather than elliptical as in most incisional biopsies done with a scalpel. Incisional biopsies can include the whole lesion (excisional), part of a lesion, or part of the affected skin plus part of the normal skin (to show the interface between normal and abnormal skin).
A skin biopsy for the measurement of epidermal nerve fiber density is an increasingly common technique for the diagnosis of small fiber peripheral neuropathy. [13] Physicians can biopsy the skin with a 3-mm circular punch tool and immediately fix the specimen in 2% paraformaldehyde lysine-periodate or Zamboni's fixative. [20]
Generally a skin biopsy: For punch biopsies, a size of 4 mm is preferred for most inflammatory dermatoses. [2] Panniculitis or cutaneous lymphoproliferative disorders: 6 mm punch biopsy or skin excision. [2] A superficial or shave biopsy is regarded as insufficient. [2]
A curette is a surgical instrument designed for scraping or debriding biological tissue or debris in a biopsy, excision, or cleaning procedure.In form, the curette is a small hand tool, often similar in shape to a stylus; at the tip of the curette is a small scoop, hook, or gouge.
The biopsy material is then sent to a laboratory to be evaluated by a pathologist. A skin biopsy can be a punch, shave, or complete excision. The complete excision is the preferred method, but a punch biopsy can suffice if the patient has cosmetic concerns (i.e. the patient does not want a scar) and the lesion is small.
Anetoderma can be diagnosed clinically. But if the diagnosis proves to be difficult, a skin biopsy—ideally a punch biopsy—can be carried out to include the mid dermis. [18] Under a microscope, the epidermis of anetoderma exhibits a nearly total loss of elastic fibers in the reticular and papillary dermal layers.
