The thyroid nodule is a very common thyroid disease in adults, with an increasing incidence. Cancers are found in 10~14% of patients presenting with palpable thyroid nodules. As FNA is the single best test for evaluation of thyroid nodules, FNA should be the first test in patients with a thyroid nodule 1cm or larger. According to the FNA findings, thyroid nodules are usually classified into three categories: malignant, benign, and suspicious/indeterminate lesions. Malignant nodules should be treated by surgery, while benign nodules can be followed without any medical treatment or suppressed by L-T4 treatment. Patients with suspicious/indeterminate nodules, are malignant in 10% to 20% of cases, should be advised to undergo surgery.

Lentigo maligna, a precancerous tumor arising from abnormal melanocytes, is a chronic, slowly progressive, pigmented lesion with a range of colors from pale tan to black and an irregular shape, The commonest location of lentigo maligna is the face during the sixth and seventh decades of life. Less frequently, the lesion occurs on an extrafacial area such as the hand or lower leg. In the late stage, lentigo maligna transforms into invasive malignant melanoma. A 50-year-old male patient had a well-defined, black pigmented patch on the right sole for 30 years. The histopathologic examination revealed numerous vacuolated melanocytes clusters at the dermo-epidermal junction with invasion of the epidermis. There was no evidence of dermal invasion by atypical melanocytes.
