Background: Kaposi's sarcoma (KS) is a vascular malignant tumor characterized by human herpesvirus 8 infection of neoplastic cells. Diffuse cutaneous lesions represent the classical clinical presentation. This case report describes the first fine needle aspiration cytology findings of a primary lymph nodal KS, a rather unusual localization of the disease.
Case: A 28-year-old, apparently healthy man saw a surgeon for right inguinal node enlargement without other symptoms. The clinician performed fine needle aspiration and made a preliminary diagnosis of a neoplasm of probable mesenchymal origin, not otherwise specified. The lymph node was excised, and the final histologic diagnosis was primary lymphoadenopathic KS. A serologic test revealed antibody positivity for HIV.
Conclusion: The diagnosis of primary KS of the lymph node, in the absence of any other clinical manifestation, was the first sign of HIV infection.

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.

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).

This study aimed to evaluate the impact of different manipulation methods and storage environments on the microstructural, chemical, and mechanical properties of calcium-enriched mixture (CEM) cement. Four sample groups were examined, including nondried (ND-I) and dried (D-I) groups placed directly in an incubator, dried samples stored in phosphate-buffered saline (PBS) (D-P), and dried samples stored in distilled water (D-W). Various analyses, including Vickers microhardness, compressive strength, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) were conducted after incubating the samples for 7 days.

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.
