Serum Inh-B cannot serve as a stand-alone marker of persistent spermatogenesis in men with NOA. Although limited, evidence on serum AMH and serum/seminal AMH do not support their diagnostic value in men with NOA.

ObJEctIVE: thyroglossal duct cyst (tGDc) carcinoma is a rare entity and its management is controversial. the aim of this retrospective study was to: (a) identify patients with tGDc carcinoma followed up in our clinic and (b) study specific characteristics of the disease and their association with thyroid carcinoma. DEsIGN: Medical files of patients with tGDc carcinoma were reviewed and tumour characteristics, lymph node metastases, treatment and follow-up were evaluated. rEsULts: A total of 6 patients, 4 females and 2 males, mean age 39.3 years (median 33.5), were treated for papillary thyroid carcinoma arising in a tGDc. carcinoma of the thyroid gland was found simultaneously in 4 of these patients, while in one patient thyroid carcinoma developed 10 years after the diagnosis of tGDc carcinoma. A variable clinical picture and presentation was recorded. the most aggressive manifestation of the disease in terms of local infiltration, local recurrence and lymph node metastases was observed in our youngest patients. cONcLUsIONs: Long-term follow-up is necessary for patients with thyroid carcinoma arising in a tGDc. In view of the frequent co-existence of thyroid cancer in these patients, we would recommend detailed thyroid evaluation and, eventually, total thyroidectomy at initial diagnosis of tGDc carcinoma.

Background: The association between chronic lymphocytic thyroiditis (CLT) and thyroid cancer is an interesting topic. The aim of the present study was to evaluate if demographic and histological characteristics as well as the long-term outcome of thyroid cancer was different in children and adolescents with and without CLT. Methods: The medical records of children and adolescents (%21 years old) were reviewed. The following data were recorded: gender, year and age at diagnosis, family history of thyroid cancer, history of external radiation therapy, histological type (papillary and variants, follicular and variants), tumour size, multifocality, infiltration of thyroid parenchyma or surrounding soft tissues, vascular invasion, presence of lymph node and distant metastases. Information about the presence of TgAb and TPOAb was also collected. Results: One hundred eight children and adolescents (median age 19.0, interquartile range 4.0 years) were diagnosed with differentiated thyroid carcinoma (DTC); 31 patients (28.7%) presented histological characteristics compatible with CLT. Infiltration of thyroid parenchyma was more frequent in patients with CLT compared to patients without (74.2% vs 48.1% respectively, PZ0.024). Familial papillary thyroid carcinoma (PTC) was more frequent in patients with CLT compared to those without CLT (20.7% vs 2.8% respectively, PZ0.009). There was no better outcome with respect to the presence of CLT or not. Conclusions: Children and adolescents with CLT present more frequently familial PTC as well as thyroid cancer with invasive characteristics.

Serum AMH levels differentiate control from subfertile men but not men with different causes of subfertility.

BackgroundParathyroid metastatic disease from thyroid cancer has not been studied extensively, mainly due to the need for parathyroid preservation during thyroid surgery.MethodsWe reviewed files from 1,770 patients with thyroid cancer followed up in our department and 10 patients with parathyroid metastases (0.5%) were identified. Patient and tumor characteristics were recorded.ResultsSix out of ten patients had metastases from papillary thyroid cancer, three from follicular thyroid cancer and one from anaplastic thyroid cancer. In nine patients parathyroid infiltration from thyroid cancer was found in direct contact with the thyroid cancer, and in one patient metastatic foci were observed not in continuity with the thyroid cancer.ConclusionsParathyroid involvement, although infrequent, may occur in thyroid cancer independently of patient age and tumor size. The clinical significance of such event is not clear. The influence on disease outcome remains to be elucidated.
