“…1,10,16,17 Certain key radiologic features outlined above distinguish these two tumors with a good degree of accuracy. 10,12 In these situations, the pathologist is only required to confirm the diagnosis.

“…21 However, if they present as pelvic or retroperitoneal masses where other lesions enter into a differential diagnosis, FNAC plays an important role in their evaluation. 12,22 Raised tumor markers such as AFP, b-HCG, or placental alkaline phosphatase levels can be extremely useful corroborative evidence. 22 In conclusion, aspirated material from pediatric intraabdominal masses needs to be interpreted in conjunction with clinical parameters such as patients' age at presentation, key radiological findings and biochemical marker levels for an accurate and clinically meaningful diagnosis.…”

The pathologist forms a very important part of the clinical team in the management of pediatric intra-abdominal masses in giving a rapid, accurate diagnosis for these potentially curable tumors. Fine-needle aspiration cytology (FNAC) is an invaluable tool in this regard when interpreted with clinicoradiologic parameters. With this in mind, we decided to evaluate the role of FNAC in pediatric abdominal masses in our institution. A total of 83 of 105 FNAC accessioned in the pathology department over 5 years (2003-2007) were studied. These included only cases where a diagnosis could be offered on cytology. Detailed clinicoradiological features were obtained from hospital records. Cytomorphological features examined included cellularity, architectural pattern, background, key cellular details. Immunocytochemistry were done where necessary. Lesions diagnosed on FNAC included Wilms' tumor (19), lymphoma (10), neuroblastoma (6), hepatoblastoma (5), PNET (5), rhabdomyosarcoma (2), DSRCT (2), germ cell tumor (6), and miscellaneous tumors (7). Definite diagnosis could be offered on cytomorphology in 74.7% (62) cases, while in 25.3% (21) cases only a diagnosis of round cell tumor could be offered. Concordance with final histopathology and biochemical parameters was subsequently obtained in 79/83 (95.5%) of cases. A clinically relevant classification is possible on FNAC in pediatric abdominal tumors when interpreted with clinicoradiologic parameters. This obviates the need for a more time-consuming biopsy procedure in critical situations and in stage II nephroblastoma where it is contraindicated.

“…Calcification of the mass is not uncommon. Other neoplasms that cause diffuse peritoneal masses in children include rhabdomyosarcoma, metastatic germ cell tumor, spread from retroperitoneal tumors including neuroblastoma and Wilms tumor, malignant mesothelioma, peritoneal carcinomatosis, and peritoneal seeding of intracranial tumors through ventriculoperitoneal shunts (80).…”

Intraperitoneal solid tumors are far less common in children than in adults, and the histologic spectrum of neoplasms of the peritoneum and its specialized folds in young patients differs from that in older patients. Localized masses may be caused by inflammatory myofibroblastic tumor, Castleman disease, mesenteric fibromatosis, or other mesenchymal masses. Inflammatory myofibroblastic tumor is a mesenchymal tumor of borderline biologic potential that appears as a solitary circumscribed mass, possibly with central calcification. Castleman disease is an idiopathic lymphoproliferative disorder that appears as a circumscribed, intensely enhancing mass in the mesentery. Mesenteric fibromatosis, or intra-abdominal desmoid tumor, is a benign tumor of mesenchymal origin associated with familial adenomatous polyposis. Mesenteric fibromatosis appears as a mildly enhancing, circumscribed solitary mass without metastases. Diffuse peritoneal disease may be due to desmoplastic small round cell tumor (DSRCT), non-Hodgkin lymphoma, or rhabdomyosarcoma. DSRCT is a rare member of the small round blue cell tumor family that causes diffuse peritoneal masses without a visible primary tumor. A dominant mass is typically found in the retrovesical space. Burkitt lymphoma is a pediatric tumor that manifests with extensive disease because of its short doubling time. The bowel and adjacent mesentery are commonly involved. Rhabdomyosarcoma may arise as a primary tumor of the omentum or may spread from a primary tumor in the bladder, prostate, or scrotum. Knowledge of this spectrum of disease allows the radiologist to provide an appropriate differential diagnosis and suggest proper patient management.

Malignant intraperitoneal neoplasms of childhood

Abstract: While rare in pediatrics, intraperitoneal neoplasms occur in children, and CT is useful in identifying these peritoneal neoplasms.
