background: the differential efficacy between long gnrh agonist with antagonist can partly be due to the preexisting differences in the early antral follicles before ovarian stimulation. objective: to compare the effect of pretreatment by estradiol with gnrh antagonist on antral follicular size coordination and basal hormone levels in gnrh antagonist protocol. materials and methods: on cycle da...

A 52-year-old Japanese woman who was eventually diagnosed with primary follicular lymphoma of the duodenum showed atypical endoscopic features, namely, erosions with peripheral whitish edematous mucosa. Initial biopsy specimens taken from the erosions revealed insufficient numbers of lymphoma cells for histological diagnosis. Subsequent biopsy specimens from the peripheral mucosa containing the...

In this issue of the JCEM, Walsh et al. (1) report the analytical validation of a molecular diagnostic method for indeterminate fine-needle aspiration (FNA) thyroid samples. Together with previous reports describing clinical performance and cost effectiveness of this method, this study highlights the capability of such a molecular test to reduce unnecessary surgery for benign thyroid diseases (...

Follicular carcinoma of the thyroid usually presents as nodules with rare cases showing metastasis at diagnosis. But occult follicular carcinoma without any thyroid enlargement and presenting as multiple lytic bone lesions is unusual and relatively rare. Here we report a 66-year old Malay man presenting with occipito-parietal swelling for last two years. He had no thyroid enlargement; no thyroi...

We report an unusual case of a 70-year-old male with history of hereditary spherocytosis (HS) and secondary paraspinal extramedullary hematopoiesis with a concurrent follicular lymphoma. The lesion presented as a thoracic paraspinal mass of 9 cm, extending longitudinally between T6 and T9 vertebral bodies. Incisional biopsy revealed that this mass included mature hematopoietic tissue compatible...

BACKGROUND Hyalinizing trabecular tumors (HTT) are rare follicular cell-derived tumors of the thyroid gland that are infrequently reported in otolaryngology literature. We present here an interesting case of HTT which provides the basis for review of this entity's clinical characteristics, criteria useful in making the diagnosis, and any currently available therapeutic modalities. CASE PRESEN...

We used proposed standard morphologic criteria as a guideline to conduct a 10-year retrospective review of thyroid fine-needle aspiration specimens that were originally interpreted as "follicular lesion of undetermined significance" and followed by surgical intervention. We sought to investigate whether the indeterminate diagnosis could be minimized by assessing various cytomorphologic features...

Abstract Background A hypertrophic / vegetating variant of Darier disease causing massive verruciform genital tumors is exceedingly rare. Case presentation woman in her late 50s underwent wide resection vulva and inguinal skin due to lesion. She had crusted keratotic plaques with appearance follicular keratosis (with a greasy, warty texture) the back, neck, face, extremities for 27 years. Previ...

Aim: In this study, the role of fine needle aspiration biopsy (FNAB) evaluated with Bethesda System in diagnosis thyroid nodules was investigated. Materials and Methods: Total 2284 FNAB materials 1846 patients were performed Pathology Department Kutahya Health Sciences University, Evliya Celebi Traning Research Hospital between 2016 2019 reported according to category. Among these cases, diagno...

Major purpose of the management of thyroid nodules is to distinguish between malignant nodules and the benign ones. Nodules with the cytology result Atypia of Undetermined Signifi cance or Follicular Lesion of Undetermined Signifi cance are still a diagnostic challenge. Initial presentation of the Bethesda System was based on 7% diagnosing rate and around 5-15% malignancy rate for these nodules...
