A Unique Case of Bilateral Hürthle Cell Adenoma in an Adolescent

Unusual Thyroid Mass in an Adolescent Patient

Hurthle cell tumors are rare follicular-derived thyroid neoplasms. Hurthle cell tumors may be benign or malignant. Workup includes imaging, fine needle aspiration, and treatment usually consists of observation versus thyroidectomy. We describe a case of Hurthle cell adenoma in an adolescent; to the best of our knowledge, this represents only the third case described in the English literature of adolescent Hurthle cell adenoma.

Hurthle cell carcinoma in childhood: A retrospective analysis of five cases and review of pediatric literature

BACKGROUND

the available studies on Hurthle cell carcinoma (HCC) in pediatric age are scarce and based on isolated case reports. Aims of the present study were to review the available pediatric literature on HCC (2000-2019), to describe the cohort of children with this cancer histotype, and to estimate its relative prevalence in pediatric age.

PROCEDURE

We retrospectively reconstructed an HCC course in five patients < 19 years who were identified in our departments during the period 2000-2019, and we reviewed the available pediatric studies on this differentiated thyroid cancer (DTC) variant.

RESULTS

HCC occurred with a relative prevalence of 5.8% at a median chronological age of 12.5 years. None of HCC patients exhibited, at diagnosis, thyroid dysfunction, extensive lateral neck disease, or distant metastases, and all showed a persistent remission over time. Three patients showed, at diagnosis, antecedents of other diseases (Hashimoto's thyroiditis, neurofibromatosis type 1, and osteosarcoma).

CONCLUSIONS

(1) In childhood, the relative prevalence of HCC among different thyroid cancer histotypes is 5.8%, that is close to the one previously reported both in the general population and in other less numerous children's cohorts; (2) HCC may develop even early, at the age of 7; (3) in childhood, HCC does not seem to have a more aggressive behavior when compared with other DTC histotypes; (4) antecedents of other diseases are not infrequent in the history of children with HCC.

Typical manifestations of Hürthle cell adenoma of the thyroid on contrast-enhanced CT: A case report

RATIONALE

Hürthle cell adenoma (HCA) of the thyroid is a rare thyroid tumor, and there are limited studies on the contrast-enhanced computed tomography (CT).

PATIENT CONCERNS

We report the case of a 63-year-old woman with gradual enlargement of the thyroid over 10 years.

DIAGNOSES

Preoperative contrast-enhanced CT revealed typical lesion characteristics of HCA, confirmed by postoperative pathology.

INTERVENTIONS

Left thyroidectomy and partial right thyroidectomy were performed on the patient after general anesthesia.

OUTCOMES

At follow-up of 12 months after surgery, the patient was in good health without recurrence.

LESSONS

The typical imaging features of HCA on contrast-enhanced CT are helpful for the early diagnosis of thyroid eosinophilic adenoma. This will provide an important basis for the preoperative diagnosis and treatment strategy of HCA of the thyroid in future.
