Abstract
Needle aspiration cytology was very useful in the diagnosis of skin metastases of carcinoma of internal organs.
In semears from the aspirated material, 41 out of 43 cases of skin metastases were cytologically positive. In the remaining 2 negative cases, adequate carcinoma cells could not be obtained.
Two aspirated cases of cutaneous metastases of renal carcinoma and another two of hepatocellular carcinoma which were found prior to primary lesions were reported in detail.
In the observation of smears from cutaneous metastases, it is the most important to find the characteristics of carcinoma cells in those smears and this is considered to be of help for elucidating their primary lesions.
