剃须和打孔活检是医生管理皮肤病的基本程序。这些基于办公室的程序可以诊断可疑的皮肤病损，包括可能的恶性肿瘤。方法包括浅表刮取活检、碟状切除、穿刺活检和椭圆形切除。浅表刮片活检可用于隆起的病变。对于扁平或色素性病变可进行碟状活检。打孔活检产生全层样本，可用于需要真皮或皮下组织进行诊断的病变。疑似黑色素瘤的活检指征仍有争议。通过更快、更便宜的碟状活检或更耗时、侵入性椭圆切除活检可以获得足够的组织。
Shave and punch biopsies are essential procedures for physicians who manage skin conditions. These office-based procedures can diagnose questionable dermatologic lesions, including possible malignancies. Approaches include the superficial shave biopsy, saucerization excision, punch biopsy, and elliptical excision. A superficial shave biopsy can be used for raised lesions. A saucerization biopsy may be performed for flat or pigmented lesions. Punch biopsies yield full-thickness samples and can be used for lesions that require dermal or subcutaneous tissue for diagnosis. Indications for biopsy of suspected melanoma remain controversial. Sufficient tissue may be obtained with the quicker, less costly saucerization biopsy or the more time-consuming, invasive elliptical excisional biopsy.
