Patient presents with signs and symptoms suggestive of neuroblastoma, a childhood cancer originating from immature nerve cells.  Presenting complaints may include abdominal pain, abdominal mass, fatigue, bone pain, fever, weight loss, and Horner syndrome (ptosis, miosis, anhidrosis).  Physical examination findings can include palpable abdominal mass, hepatomegaly, lymphadenopathy, and neurological deficits.  Differential diagnosis includes Wilms tumor, lymphoma, rhabdomyosarcoma, and other childhood malignancies.  Initial workup includes complete blood count with differential, comprehensive metabolic panel, urine catecholamines (vanillylmandelic acid, homovanillic acid), imaging studies such as abdominal ultrasound, CT scan of the abdomen and chest, and MIBG scan.  Diagnosis is confirmed by biopsy and histopathological examination revealing neuroblastic cells, often with Homer-Wright rosettes.  Staging workup may involve bone marrow biopsy and aspiration, bone scan, and additional imaging studies to assess metastatic spread.  Treatment planning for neuroblastoma is risk-stratified based on age, stage, and biological features of the tumor.  Treatment modalities include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, and stem cell transplantation.  Patient education and family support are crucial components of neuroblastoma management.  Prognosis and long-term follow-up care are discussed with the family and documented.  ICD-10 code C74.9 (malignant neoplasm of unspecified site, unspecified adrenal gland) or C74.1 (malignant neoplasm of adrenal medulla) may be applicable, depending on the specific location.  Appropriate CPT codes for procedures performed, such as biopsy, imaging, and treatment interventions, should be documented.
