Evaluation of the 2‐mm punch biopsy in dermatological diagnosis
1996
This prospective study was undertaken to determine whether the 2-mm punch biopsy technique yields specimens of sufficient size and quality to allow a reliable histological diagnosis to be made. A histopathological comparison was made between tissue obtained from a 2-mm punch biopsy and a standard ellipse biopsy taken from a wide range of dermatoses and benign and malignant skin tumours. In 79 of the 84 cases studied, the same histopathological diagnosis was reached with the 2-mm punch biopsy and the standard ellipse. Use of the 2-mm punch biopsy technique produces specimens which allow an accurate histological diagnosis to be made in a wide range of dermatological conditions.
