Fine needle aspiration biopsy of the major salivary glands was performed on 160 patients. In 146 patients with satisfactory samples, the cytologic diagnosis was correlated with clinical follow-up and histologic findings. There were 122 benign lesions, including 47 tumors. There were 24 malignant lesions, 10 of which were primary and 14 metastatic. The overall accuracy was 98%. The sensitivity of the technique was 87.5%. There was no false-positive diagnosis. There were three false-negative diagnoses due to sampling errors and inexperience during the initial period of the study. This study documents that needle aspiration biopsy cytology of the salivary glands is accurate, simple, rapid, inexpensive, well tolerated and harmless to the patient.

A radiopathomics model for predicting large-number cervical lymph node metastasis in clinical N0 papillary thyroid carcinoma.
Eur Radiol
January 2025
Department of Ultrasound, Chengdu Second People's Hospital, Chengdu, China.
Objectives: This study aimed to develop a multimodal radiopathomics model utilising preoperative ultrasound (US) and fine-needle aspiration cytology (FNAC) to predict large-number cervical lymph node metastasis (CLNM) in patients with clinically lymph node-negative (cN0) papillary thyroid carcinoma (PTC).
Materials And Methods: This multicentre retrospective study included patients with PTC between October 2017 and June 2024 across seven institutions. Patients were categorised based on the presence or absence of large-number CLNM in training, validation, and external testing cohorts.
The natural history of cytologically low-risk indeterminate thyroid nodules.

Department of Internal Medicine and Therapeutics, University of Pavia, 27100 Pavia, Italy.
Background: Thyroid nodules classified cytologically as low-risk indeterminate lesions (TIR3A) on fine-needle aspiration biopsy (FNAB) present a clinical challenge due to their uncertain malignancy risk. This single-center study aimed to evaluate the natural history of TIR3A nodules.
Materials And Methods: FNABs performed between July 2017 and December 2019 were retrospectively retrieved and patients with TIR3A nodules were evaluated at baseline and throughout a follow-up based on ultrasound (US) parameters and clinical data.

Department of Pathology, Yale University School of Medicine, New Haven, Connecticut, USA.
Objective: An accurate fine-needle aspiration (FNA) diagnosis of adrenal lesions may be challenging. This study was to investigate roles of imaging guidance, rapid on-site evaluation (ROSE) and additional tissue sampling in FNA diagnosis of adrenal lesions.
Methods: Adrenal FNA cases were retrieved from pathology archive.

Primary cutaneous anaplastic large cell lymphoma (ALCL) is a very uncommon type of CD30-positive T-cell lymphoma, and it very rarely affects the forehead. We report the case of a 68-year-old male presenting with an ulcerative lesion on the right forehead, initially suspected as a benign condition. Fine needle aspiration suggested a lymphoproliferative disorder, with biopsy and immunohistochemistry confirming primary cutaneous ALCL (CD30-positive, anaplastic lymphoma kinase [ALK]-negative).

Introduction: Limited information exists on next-generation sequencing (NGS) success for lung tumors of 30 mm or less. We aimed to compare NGS success rates across biopsy techniques for these tumors, assess DNA sequencing quality, and verify reliability against surgical resection results.
Methods: We used data from the Initiative for Early Lung Cancer Research on Treatment study, including patients with lung tumors measuring 30 mm or less who had surgery and NGS on biopsies since 2016.
