Thyroid tumors occur in many domestic species, but are most common in the dog, in which they are classified as follicular or medullary. During 2012-2016, we received tissue specimens or whole carcasses of 4 dogs with variable enlargement of the thyroid glands. The 2 males and 2 females were of mixed (mongrel) inbreeding, 3-4.5-y-old. All tumors had lobulated architecture forming follicular structures variably containing colloid. On immunohistochemistry of the tumors from 3 of the dogs, 2 were thyroglobulin positive, and all 3 were negative for calcitonin, confirming follicular thyroid carcinoma in 2 of the dogs. Thyroid carcinomas have not been reported previously in related mongrel dogs, to our knowledge.

Frequency of Malignancy in Multi-nodular Goiter in a Tertiary Care Hospital.

Mymensingh Med J

January 2025

Dr Md Mominur Islam, Junior Consultant (ENT), Department of ENT & Head-Neck Surgery, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh; E-mail:

Historically multi-nodular goiters have been thought of as a benign disease with a low risk of associated malignancy. Recent studies suggested that the incidence of malignancy in patients with MNG is not uncommon. With the aim of determining frequency of malignancy in multi-nodular goiter this cross sectional observational study was done at Mymensingh Medical College Hospital, Mymensingh, Bangladesh from June 2021 to March 2022.

One- or Two-Step Total Thyroidectomy for Cancer Indications: A 20-Year Retrospective Study from a Referral Center.

Ann Surg Oncol

December 2024

Department of General, Visceral, and Endocrine Surgery, Pitié-Salpêtrière Hospital, AP-HP, Sorbonne University, Paris, France.

Background: The ATA guidelines suggest lobectomy as an option for select patients with thyroid cancer (TC), but some may need completion thyroidectomy because of unfavorable characteristics on the final pathology. This study aimed to compare postoperative morbidity of patients with TC who underwent total thyroidectomy in two steps (TT2) or one step (TT1).

Methods: This was a retrospective comparative study in a high-volume endocrine surgery center.

Objectives: The authors sought to assess whether the age of 18 reflects a true pathological inflection point that justifies transitioning between pediatric and adult paradigms of care with differentiated thyroid cancer (DTC).

Methods: A retrospective chart review was conducted for patients aged 12-24 undergoing hemithyroidectomy or total thyroidectomy for papillary or follicular thyroid carcinoma from 2010 to 2020.

Results: A total of 153 patients receiving surgery for DTC were assessed for pathological stage, nodal metastasis, and thyroid neoplasm characteristics.

Electronic address:

Methylparaben (MP) belongs to the paraben class and is widely used as a preservative in personal care products, medicines, and some foods. MP acts as an endocrine disrupting chemical (EDC) on the hypothalamic-pituitary-thyroid (HPT) axis. However, the effects of MP have not yet been completely elucidated, as published results are scarce and controversial.
