Abstract

Even though Focal nodular hyperplasia (FNH) is a rare lesion of the liver in children, it is reported at increased rates in treated pediatric cancer patients. The aim of this retrospective study is to describe the clinical and radiological characteristics and clinical course of patients diagnosed as FNH after primary malignancy in childhood. We retrospectively evaluated the diagnostic work-up, radiologic findings, clinical course and outcome of 8 patients, diagnosed as FNH after pediatric cancer treatment at the Department of Pediatric HematologyOncology of the Kanuni Sultan Suleyman Training and Research Hospital and Istanbul University, Oncology Institute, between 1993 and 2011. FNH lesions were diagnosed in 8 of 1600 solid tumors (0.5%) after a median interval of 8 (2-18) years, from the termination of the antineoplastic therapy for the primary cancer. Five patients had a history of neuroblastoma and two patients had rhabdomyosarcoma and one of them had primitive neuroectodermal tumor. FNH was incidentally found at USG or MRI performed during routine follow-up. Two children underwent surgical biopsies to rule out liver metastases. The lesions were stable for a median of 12 months (3-108 months) followup, no malign transformation was detected. FNH may be encountered as a radiological finding during follow-up in pediatric malignancies without hematopoetic stem cell transplantation and may be misdiagnosed as liver metastasis. FNH should be considered in the differential diagnosis of liver lesions encountered during follow up children with cancer. After the diagnosis of these benign lesions radiologically without biopsy, close imaging follow-up is recommended.

Özet

Fokal noduler hiperplazi (FNH), çocuklarda karaciğerin nadir görülen lezyonlarından olmasına rağmen, tedavi edilmiş çocuk kanser hastalarında artmış oranlarda bildirilmeye başlanmıştır. Bu retrospektif çalışmanın amacı, çocukluk çağı primer malinitesinden sonra, FNH tanısı alan hastaların klinik ve radyolojik karakteristiklerini ve klinik gidişini tanımlamaktır. Kanuni Sultan Eğitim ve Araştırma Hastanesi ve İstanbul Üniversitesi, Onkoloji Enstitüsü Pediatrik Hematoloji-Onkoloji Bilim Dalında, pediatrik kanser tedavisinden sonra, FNH tanısı alan 8 hastanın tanısal tetkikleri, radyolojik bulguları, klinik gidiş ve sonuçları retrospektif olarak değerlendirildi. FNH lezyonları, 1600 solid tümörlü hastanın 8’inde (0.5%), primer kanser için kullanılan antineoplastik tedavinin sonlandırılmasından 8 yıl (2-18) sonra tanımlandı. Beş hasta nöroblastom, 2 hasta rabdomyosarkom, 1 hasta da primitif neuroektodermal tumor nedeniyle tedavi edilmişti. FNH lezyonları, rastlantısal olarak, USG veya MRI ile rutin izlem sırasında saptandı. İki hastaya karaciğer metastazlarını ekarte etmek için, biyopsi uygulandı. Lezyonlar 12 aylık (3-108 ay) izlemleri sırasında stabil kaldı, maliniteye dönüşüm saptanmadı. FNH lezyonlarına, radyolojik olarak hematopoetik kök hücre nakli yapılmayan maliniteli çocuk hastalarda da rastlabilinir ve bu lezyonlar karaciğer metastazı olarak yanlış tanı alabilir. FNH, kanserli çocukların izleminde karşılaşılan karaciğer lezyonlarının ayırıcı tanısında düşünülmelidir. Bu iyi huylu lezyonların radyolojik olarak tanısından sonra, biyopsi yapılmadan yakın görüntüleme ile izlem önermekteyiz.
