Diagn Cytopathol 2024; 52:E69-E75. [PMID: 38059387 DOI: 10.1002/dc.25263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/23/2023] [Accepted: 11/24/2023] [Indexed: 12/08/2023]
Abstract
Malignant rhabdoid tumor of the liver is a rare, highly aggressive primary hepatic malignancy occurring primarily in infants. Establishing a definitive diagnosis is challenging due to its rarity, non-specific clinicoradiologic findings, and overlapping morphologic features. Herein, we present the cytomorphologic and immunocytochemical characteristics of a rare case of primary hepatic Malignant rhabdoid tumor (MRT) in an infant. A 5-month-old female child presented with progressively increasing firm mass in the upper abdomen, progressive pallor, sudden onset respiratory distress, and difficulty feeding. On examination, the child had massive, firm nodular hepatomegaly. Ultrasonography of the abdomen revealed a heterogeneously hypoechoic lesion in the left lobe of the liver. Serum alpha-fetoprotein levels were within normal limits. An ultrasound-guided fine-needle aspiration cytology (FNAC) from the liver mass showed predominantly dispersed large, markedly pleomorphic tumor cells with round to oval eccentrically placed nuclei, prominent nucleoli, and moderate cytoplasm. On immunocytochemistry, tumor cells showed positivity for vimentin, cytokeratin, and EMA and demonstrated a loss of INI1, confirming the diagnosis of MRT. The index report highlights the distinctive clinicopathological features of a hepatic malignant rhabdoid tumor along with the key differential diagnoses, which may pose a diagnostic conundrum. A high index of clinical suspicion and a thorough understanding of its cytomorphological and immunochemical characteristics are crucial for an accurate diagnosis.

Review on Pediatric Malignant Focal Liver Lesions with Imaging Evaluation: Part II. Diagnostics (Basel) 2023; 13:3659. [PMID: 38132242 PMCID: PMC10743166 DOI: 10.3390/diagnostics13243659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/04/2023] [Accepted: 12/06/2023] [Indexed: 12/23/2023] Open
Abstract
Malignant focal liver lesions (FLLs) represent various kinds of epithelial and mesenchymal tumors. In pediatric patients, the understanding of pediatric liver diseases and associated imaging manifestations is essential for making accurate diagnosis and differential diagnosis. This paper will discuss the latest knowledge of the common pediatric malignant FLLs, including undifferentiated embryonal sarcoma, rhabdomyosarcoma, epithelioid hemangioendothelioma, angiosarcoma, and malignant rhabdoid tumor. Medical imaging features are not only helpful for clinical diagnosis, but can also be useful in the evaluation and follow-up of pre- and post-treatment. The future perspectives of contrast-enhanced ultrasound (CEUS) enhancement patterns of FLLs in pediatric patients are also mentioned.

[PMID: 36786382 DOI: 10.1002/dc.25115] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 01/09/2023] [Accepted: 01/31/2023] [Indexed: 02/15/2023]
Abstract
Ascitic fluid analysis is an important tool for diagnosis and staging. Cytological analysis is routinely done as a part of workup for ascites. This is challenging in paediatric malignancies where multiple differentials need to be considered at times with limited cellularity. We present a case of malignant rhabdoid tumour of liver in a young child presenting with abdominal lump and ascites. The diagnosis was offered on ascitic fluid cytology based on cytomorphology, supporting immunohistochemistry and later confirmed on biopsy. This report briefly discusses its differentials and approach to diagnosis.
