BackgroundSplenic littoral cell angioma (LCA) is an exceptionally uncommon malignant potential vascular tumor with infrequent occurrences in pediatric patients. Due to its reliance on histopathological analysis for diagnosis, LCA may be mistakenly identified as other splenic tumors. Patients with LCA may experience anemia or thrombocytopenia, but peripheral blood pancytopenia is infrequent.Case reportA 14-year-old boy presented with peripheral blood pancytopenia, necessitating hospitalization after splenomegaly was identified during a physical examination. Following the exclusion of hematological disorders, a splenectomy was conducted; histopathological examination confirmed the diagnoses of LCA. No metastases or recurrences were observed during the 8-month follow-up. To the best of our knowledge, this case represents the first instance of LCA associated with pancytopenia in a pediatric patient.ConclusionLCA can lead to iron-deficiency anemia or thrombocytopenia, with rare occurrences of pancytopenia, potentially resulting in misdiagnosis as a hematological disorder. Surgical intervention remains an effective treatment for LCA.
