Abstract :

Introduction: The clinically solitary thyroid nodule may be defined as "A thyroid swelling, which on clinical examination appears to be a single palpable nodule in an otherwise normal gland". Solitary thyroid nodule still remains a mystery for surgeons and pathologists in these days of recent advances,

Aims and objectives: To study the incidence rate of solitary thyroid nodule in different age group of population with respect to different pathology, investigations and management.

Material and methods: The present study consists of study of 100 cases of solitary thyroid nodule. Complete history was taken and full clinical examination was carried out.

Results: The sensitivity and specificity of FNAC were 74% and 100% respectively. The sensitivity and specificity of USG were73% and 85.3% respectively, hence with the use of USG along with FNAC will improve the diagnostic accuracy to a higher level. Solitary nodule thyroid (SNT) more in females (M: F 1:2.33). Duration of swelling prior to the presentation was from 6 months to 3 yrs. The incidence of malignancy in our series in STN is 18%. On FNAC majority were benign with being more common. All the lesions suspicious on FNAC (31.3%) proved to be a malignant indicating need for surgery.

Conclusion: Majority of patients are euthyroid on presentation. FNAC is first investigation of choice. USG is a useful diagnostic aid. Modified neck dissection is advised for patients with enlarged nodes in papillary carcinoma and for those pos–op patients who are diagnosed to have malignancy with lymph node metastasis.
