An Atypical Presentation, Diagnostic Challenges, and Treatment Response of a Malignant Small Round Cell Tumor in the Lumbo‐Inguinal Region of an Infant

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Malignant small round cell tumors are a heterogeneous group of aggressive neoplasms characterized by small, round cell morphology. The undifferentiated cells in these tumors exhibit a high nuclear‐cytoplasmic ratio, and definitive histologic diagnosis via light microscopy can be extremely challenging. Diagnostic accuracy significantly improves

The Atypical and Suspicious for Malignancy Categories of the WHO Reporting System for Lymph Node, Spleen, and Thymus Cytopathology: Review of their Diagnostic Utility, Limitations, and Clinical Impact

Diagnostic Cytopathology, Volume 54, Issue 6, Page 449-460, June 2026.
ABSTRACT Background Fine‐needle aspiration biopsy (FNAB) is the preferred first‐line diagnostic tool for evaluating lymphadenopathy due to its minimally invasive nature and cost‐effectiveness. However, cytopathological interpretation of lymph node FNAB remains challenging because of the wide morphological spectrum of lymphoid lesions.
