Answer

Answer

Fine-needle biopsy can be used in difficult diagnostic cases, particularly in cases of amelanotic melanomas. In experienced hands, this technique has an accuracy of more than 95% in tumors larger than 3 mm; however, false-negative and false-positive results may be obtained. Its risk of local spread is very small, an advantage over incisional biopsy. The most common complication is intralesional hemorrhage. [5]
