An apocrine hidradenoma is a benign adnexal neoplasm, usually covered by intact skin,<br />
but may show superficial ulceration and serous discharge. This feature is raising the<br />
possibility of malignancy as it was in our case of macroscopically suspicious tumor. We<br />
described cytomorphologic features of cutaneous nodule that might be a lead to the cytologic<br />
diagnosis of hidradenoma, but primary or secondary malignant tumor has been<br />
ruled out first.<br />

US-guided fine needle aspiration cytology is currently the best diagnostic tool for thyroid<br />
nodules. However, it is not sensitive and specific enough for discriminating between<br />
benign and malignant follicular tumors. The aim of this research is to make a detailed<br />
and objective determination of the morphological characteristics of cells in cytological<br />
smears of aspirated material of pathohistologically verified follicular and Hürthle adenomas<br />
and carcinoma. The research included 62 patients with cytologically diagnosed<br />
follicular or Hürthle cell tumors, and 15 patients with hyperplastic nodules. Echographic<br />
findings are divided into three groups: isoechogenic, hypoechogenic and hyperechogenic<br />
nodules. The nodules are classified by size according to the WHO pT classification.<br />
The semiquantitative analysis determined the frequency of particular morphological<br />
elements in the cytological smear. We analyzed the cellularity of the smear, cohesion<br />
between follicular cells, acinar formations, bare nuclei, characteristics of the nucleus<br />
and the cytoplasm, and the presence of colloid. The statistical analysis of cytological<br />
parameters has indicated that none of the cytological parameters alone is discriminating<br />
enough between non-tumor and tumor changes, or benign and malignant follicular<br />
thyroid nodules. The analysis of age, sex, nodule size and ultrasound findings has not<br />
shown the correlation between any of these parameters with the malignant or benign<br />
follicular tumors. The cytological analysis of the smears for patients with follicular tumors,<br />
in combination with clinical data and other diagnostic methods, contributes to<br />
more precise diagnostics, but is not sufficient for the discrimination between benign and<br />
malignant follicular tumors.<br />
