Abstract
Hamartomas are extremely rare splenic benign tumours in children. We present two cases, both in boys (6 and 8 years old), with left upper quadrant abdominal pain that were otherwise asymptomatic. Both patients showed a splenic mass on preoperative ultrasonography and magnetic resonance imaging (MRI). One patient had a focal splenic mass that was identified preoperatively with contrasted computed tomography (CT) scans. Both patients underwent a total splenectomy. Although multi-modality imaging findings were described preoperatively, the final diagnosis in each case was splenic hamartoma based on histology and immunohistochemistry. The postoperative courses were uneventful.
Highlights
Splenic tumours are relatively rare and include malignancies such as lymphomas, angiosarcomas, plasmacytomas, primary malignant fibrous histiocytomas, and metastatic disease
Splenic hamartomas or splenomas, which were described in 1861 by Rokitansky, are extremely rare benign tumours with fewer than 150 cases having been reported in the literature [3]
We report the cases of two paediatric patients with a solid lesion of the spleen, who required splenectomies and were pathologically diagnosed with splenic hamartomas
Summary
Splenic tumours are relatively rare and include malignancies such as lymphomas, angiosarcomas, plasmacytomas, primary malignant fibrous histiocytomas, and metastatic disease. Splenic hamartomas or splenomas, which were described in 1861 by Rokitansky, are extremely rare benign tumours with fewer than 150 cases having been reported in the literature [3]. The majority of these cases were found in adult patients, and only 20% of the cases were in children [4]. We report the cases of two paediatric patients with a solid lesion of the spleen, who required splenectomies and were pathologically diagnosed with splenic hamartomas. Physical examination revealed a palpable spleen 3 cm below the costal margin He had no significant past medical history, and the laboratory findings (such as blood routine test, serum chemistry test, and tumour biomarker) were unremarkable. No complications developed during postoperative follow-up, and the patient was asymptomatic 17 months after surgery
