Papillary thyroid carcinoma in a 5-year-old child-case report

Papillary thyroid carcinoma in an 8-year-old Ethiopian child: A case report with literature review

Thyroid nodular disease can present in different forms, such as a solitary nodule, multinodular goiter, nodular goiter caused by autoimmune goiter, and nonpalpable thyroid nodules. Among children, thyroid cancer is the most common type of endocrine cancer. Pediatric thyroid cancer is usually detected as a neck mass without any symptoms, leading to variable stages of progression when diagnosed. Papillary thyroid carcinoma is the most common type of thyroid cancer in children with thyroid nodules. We are presenting a case of an 8-year-old male child who was referred to Jimma Medical Center after he developed swelling on the right side of his neck. On examination, multiple, matted 8 × 6 cm, firm to hard, non-tender right lateral neck masses were found, which moved with swallowing. Thyroid function tests were normal. An ultrasound diagnosis of thyroid carcinoma and a cytologic diagnosis of suspicion for papillary thyroid carcinoma (Bethesda V) was made, and an excisional biopsy was advised. A total thyroidectomy was done. A histopathology diagnosis of Papillary thyroid carcinoma (Classic variant) was made. This is an unusual case of Papillary thyroid carcinoma in an Ethiopian child, with plenty of examples previously recorded in the literature but no such report of its occurrence in our setup to our knowledge. When children under 10 have cervical masses, thyroid cancer should be considered. The evaluation of a palpable thyroid mass typically begins with a blood test to check thyroid function, along with ultrasound and fine-needle aspiration biopsy. Currently, fine-needle aspiration biopsy is the most reliable way to diagnose malignancy and determine the appropriate surgical approach. In most cases, treatment will involve a total thyroidectomy. Lymph node dissection is necessary only if lymph node disease is detected during preoperative evaluation.

Childhood Malignancies-Clinico-demographic Profile of Patients Attending the Department of Otorhinolaryngology at a Tertiary Care Centre in North-East India

INTRODUCTION

Malignancies in children are different from those found in adults and are a significant cause of childhood mortality.They have varied clinical presentation depending on site and type of disease.It is essential to recognize the early signs and symptoms of malignancies in childhood, especially those involving head and neck region, so as to reduce childhood mortality and morbidity.

MATERIALS

A total of 2384 children were admitted over a period of 7 years. Out of these, 1004 fulfilled the inclusion criteria and were chosen for further evaluation.They were thoroughly evaluated by undertaking a detailed history and clinical examination.Whenever required, additional investigations were performed.After carrying out the necessary investigations, the cases were accordingly managed. Data was evaluated using proper statistical tools.

RESULTS

Out of 1004 cases fulfilling the inclusion criteria, 42 turned out to be malignant, with a male-to-female ratio of 1:1.2. Malignancies in children were more common in the age group of 11-18 years, followed by 1-5 years,6-10 years and 0-1 years,with rates of 59.5%, 21.4%, 16.7% and 2.4% respectively. A wide variety of tumour types were recorded,e.g.,Hodgkin's lymphoma,non-Hodgkin's lymphoma,acute leukemia,papillary carcinoma thyroid, nasopharyngeal carcinoma,Langerhans cell histiocytosis,rhabdomyosarcoma, olfactory neuroblastoma and salivary gland neoplasm.

CONCLUSION

Incidence of head and neck tumors in pediatric age group was found to be 1.76% with lymphoma being the most frequent.Commonest age of presentation was above 10 years. There was an overall female predominance with a male:female ratio of 1:1.2. Awareness of a potential malignancy and careful follow-up of children with suspicious head and neck cancers is mandatory for early diagnosis and prompt treatment.

Long-term Follow-up of a Toddler with Papillary Thyroid Carcinoma: A Case Report with a Literature Review of Patients Under 5 Years of Age

Papillary thyroid cancer (PTC) is extremely rare in children. Herein, we present a case diagnosed with PTC at 15 months of age. We conducted a literature review of the published cases with PTC under five years of age. A 1.25-year-old male patient had initially presented with a complaint of progressively enlarging cervical mass that appeared four months earlier. On physical examination, a mass located in the anterior cervical region with the largest measurements of around 3x3 cm was detected. Cervical and thyroid ultrasonography showed a 50x27 mm solid mass in the right lateral neck. Excisional biopsy revealed a follicular variant of PTC with capsular invasion. Subsequently, he underwent a complementary total thyroidectomy. He was diagnosed with intermediate-risk (T3N0M0) PTC. He developed permanent hypoparathyroidism. In the first year of the operation, he was treated with radioiodine ablation (RAI) since basal and stimulated thyroglobulin (Tg) levels tended to increase. Whole-body scintigraphy was normal in the first year of RAI ablation. On levothyroxine sodium (LT4) treatment, levels of thyroid stimulating hormone (TSH) and Tg were adequately suppressed. He is now 8.5-years-old and disease-free on LT4 replacement therapy for seven years and three months. Pediatric PTC has different biological behavior and an excellent prognosis compared to adults. The optimal treatment strategy for pediatric TC is total thyroidectomy, followed by RAI ablation. Post-operative management should include regular follow-up, TSH suppression by adequate LT4 therapy, serial Tg evaluation, and radioiodine scanning when indicated.

Unusual case of papillary thyroid carcinoma mimicking paraganglioma in a 16-year-old girl

BACKGROUND

Papillary thyroid carcinoma is a common neoplasm arising from follicular cells of the thyroid. Differentiating the neck mass between thyroid paraganglioma and papillary thyroid carcinoma is often difficult.

CASE REPORT

We report a 16-year-old girl with painless neck mass. Physiological goiter was suspected initially but we found papillary thyroid carcinoma.

RESULTS

CT neck revealed hyper vascular lesions in bilateral lobes of thyroid. DSA imaging was done for further evaluation which showed high flow fistulous type of lesion supplying from superior thyroidal artery raising suspicion of paraganglioma. Postoperative biopsy ultimately revealed papillary carcinoma of thyroid in the background of hashimotos' thyroiditis with metastatic deposits in neck lymph nodes.

CONCLUSION

Thyroid paraganglioma is a rare type of tumor, it arises from inferior laryngeal paraganglioma within thyroid capsule and is as thus difficult to distinguish from thyroid carcinomas. A biopsy is the best diagnostic choice but immunohistochemistry is the only investigation which is considered as the gold standard for distinguishing between these two diseases.
