Fine needle aspiration cytology- an accurate method for diagnosis of cutaneous and subcutaneous metastases

Abstract

Background: Cutaneous metastases from carcinoma are relatively uncommon, usually representing late events in the course of internal malignancies and indicate a dismal outcome of patients. Aim of the study was undertaken to evaluate the role of FNAC as a diagnostic tool for diagnosis of cutaneous metastases of various internal malignancies as it is of great value in the early diagnosis.Methods: Study of cutaneous metastases was undertaken for the period from April 2013 to July 2017. Out of over 12000 cytology cases, 25 cases were diagnosed as cutaneous metastases. Fine needle aspiration was done using 22-gauge needle without anaesthesia and smears were air dried and stained with MGG.Results: Out of 25 patients diagnosed with cutaneous metastases on cytology, 11 were males and 14 females with age ranging from 20-75 years. Chest wall was the most common site of metastases. Adenocarcinoma and Non-Hodgkin’s Lymphoma were the most common cytomorphological types observed.Conclusions: FNAC is minimally invasive, safe, rapid and reliable method for the diagnosis of cutaneous metastases.

Diagnostic utility of fine needle aspiration cytology in the evaluation of neoplastic cutaneous nodular lesions: experience from tertiary care institute

“…Srivastava et al16, Patel et al, Rastogi et al also noticed adenocarcinoma as most common cutaneous metastatic tumor. 10,17 The sensitivity FNA in the diagnosis of neoplastic nodular lesions in our study was 98.7% which was slightly less than the study by Jain et al18 while it is slightly more than study by Kusumastuti et al 19 The specificity and diagnostic accuracy of neoplastic nodular lesions was 94.6% and 97.4% respectively which was comparable to study by Jain et al 18…”
