Background: Evaluation of patients with cutaneous or subcutaneous nodules,
especially if they are multiple, is a diagnostic challenge. This study aimed to investigate
smears and cell blocks and compare them with examination of tissue biopsies.
Methods: Fine needle aspiration cytology (FNAC) and cell blocks were done for 225
cutaneous and subcutaneous nodules. Furthermore, histopathological examination was
conducted using biopsies.
Results: According to tissue biopsy, benign lesions constituted the most common
finding in % cases. The detected cases were lipoma in .% cases,
adipose tissues in .% cases, fibro lipomas .%, fibromas .%,
juvenile fibroma .%, neurofibroma in cases .%, sebaceous cyst in cases
.%, implantation cyst, or dermoid cyst cases .%, pilomatrixoma cases
.%, seborrheic keratosis cases .% and Madura foot actinomycosis in
cases .%. )ntermediate lesions of atypical lipoma were found in cases .%.
Malignant lesions were cases .% as follows: cases .% basal cell
carcinoma, cases .% squamous cell carcinoma and cases .% basosquamous
cell carcinoma. For FNAC smear examination, the sensitivity test was .% and the
specificity was .%. For cell blocks examination, the sensitivity and specificity tests
were .%, and %, respectively.
Conclusion: Smear cytology is an easy and quick test for diagnosing skin nodules.
Performance of cell blocks improves sensitivity and specificity of smear outcome, but
both should be attempted, because the smear may be ineffective in some cases while a
cell block cannot be performed in others.
