The normal thyroid gland in an adult weighs 15-40 gm and is composed of two lateral lobes connected in the midline by a broad isthmus. The major function of the thyroid gland is to maintain a high rate of metabolism, which is done by means of iodine containing thyroid harmones. The thyroid is one of the most labile organs in the body and responds to numerous stimuli such as puberty, pregnancy, physiologic stress and various pathologic states. Herein, we present a rare case of PCT associated with HT involving the bilateral cervical lymph nodes.

A 16-year-male patient came with complaints of diffuse enlargement of thyroid from past nine months with no associated symptoms. The swelling was of size 5 × 4 cm. Patient complains of multiple swellings as well in the cervical region from past five months, of size 2 × 2 cm, as mobility was restricted and firm. Ultrasonography (USG) was done and diagnosed as PCT. Fine needle aspiration cytology (FNAC) was done from thyroid and from lymph nodes and diagnosed as PCT metastasizing to lymph nodes. Complete thyroidectomy was done and we received a thyroid specimen of size 5 × 5 ×3 cm, firm, externally show multiple papillae like projections [Figure 1]a. Cut section shows lymph node like architecture, gray white with normal thyroid tissue [Figure 1]b. We also received 10 lymph nodes. Largest node was measuring 2.5 × 1× 0.5 cm [Figure 2]. Histopathologically, we diagnosed it as PCT associated with HT and 5/10 cervical lymph nodes show metastatic deposits.

Thyroid gland, which plays a major role in day-to-day life is a common problem in females of all age groups. Hashimoto's thyroiditis (HT), also called chronic lymphocytic or autoimmune thyroiditis, is part of the spectrum of autoimmune thyroid diseases and is associated with various degrees of thyroid hypofunction and circulating antibodies to thyroid antigens.[1],[2] By strict criteria, it is a histological diagnosis that was first described by Hakaru Hashimoto, a Japanese surgeon working in Berlin, Germany.[3] The cause of HT is thought to be a combination of genetic susceptibility and environmental factors.[4] The incidence of HT is estimated to be 10-15 times higher in females; its annual incidence worldwide is estimated to be 0.3-1.5 cases per 1000 individuals.[5] Autoimmune disorders like Hashimotos does not pose a major serious problem, but carcinomas in thyroid should need appropriate treatment. Although the link between chronic inflammation and cancer is well established, the association between HT and papillary thyroid carcinoma has been controversial in medical bibliography since its initial description by Dailey et al., in 1955. The aim of our study was to determine the prevalence of PCT and HT coexistence and to assess the relationship between Hashimotos and the development, presentation, management and outcome of the PCT.

The prevalence of Hashimotos is significantly higher in patients with PCT. These patients typically have a dominant nodule, with 44% of which are discovered incidentally on routine examination. The prognostic variables at the time of a diagnosis of PCT and the approach to management are not altered by the presence of co-existent Hashimotos. In addition, the rate of surgical complications was not higher in patients with co-existent Hashimotos disease.

In the present case, FNAC from thyroid show highly cellular smears arranged in papillary pattern, showing nuclear grooving and inclusions [Figure 3]. FNAC from cervical lymph nodes also show the same picture [Figure 4]. Histopathologically, it shows a lesion consisting of multifocal dense lymphoid aggregates with germinal centers, with foci of Hurthle cells. The other areas show a neoplastic lesion comprising of papillae with central fibro vascular core and follicles lined by cells with optically clear nucleus with nuclear grooving [Figure 5]. Cytoplasm is scant and clear. Foci of calcific sperules (Psammoma bodies) seen with intervening normal thyroid tissue.

Sections from lymph nodes show (5/10) well-defined tumor deposits [Figure 6]. Isthmus is normal and no capsular or vascular invasion is seen.

The main aim of presenting this case is to highlight the importance of co-existence of PCT with Hashimotos, and to explain that there is an increased prevalence of HT in patients with PCT. The presence of co-existent HT does not affect the diagnostic evaluation or management of PCT. Generally, thyroid lesions are more commonly seen in females, but in this case, we present a 16-year-male boy, who is of unusual age group to present. The survival of patients who have PCT may be superior in co-existent with HT. The outcome and prognosis of PCT appear to be improved with the presence of co-existent HT.[6],[7]
