He presented with pallor, intermittent fever, and recurrent respiratory infections from an early age, along with anemia, splenomegaly, hepatomegaly, cervical lymphadenopathy, and growth failure noted in initial investigations. Still's disease was initially considered as the most likely differential diagnosis, leading to the initiation of treatment with methylprednisolone; however, the parents did not follow-up with the treatment. The child returned at 5 years old with appendicitis, which was surgically removed, and parents reported recurrent episodes of arthralgia and joint swelling accompanied by nearly daily fever. Although the child experienced delayed motor development, his cognitive abilities were normal. Genetic analysis identified a homozygous likely pathogenic variant in the <i>MVK</i> gene and a heterozygous likely pathogenic variant in the <i>MEFV</i> gene. The child remains reliant on corticosteroids, with limited response to colchicine and improvement noted after transitioning from tocilizumab to infliximab. The latest follow-up demonstrated significant improvement with no fever, joint swelling, or lymphadenopathy; however, signs of growth failure persist.

This case report aims to highlight the importance of prompt diagnosis and management of mediastinal mature cystic teratomas in pediatric patients. We present the case of a 10-year-old female patient who presented with persistent chest pain and dyspnea. Imaging studies, including a chest X-ray and contrast-enhanced chest CT scan, revealed a large, well-circumscribed anterior mediastinal mass with calcifications. The patient underwent a right thoracotomy, resulting in the excision of a 6 × 5 × 5 cm mature cystic teratoma. Histopathological examination confirmed the diagnosis. The patient had an uneventful recovery and was discharged in stable condition. Mediastinal mature cystic teratomas pose diagnostic challenges due to their nonspecific symptoms and heterogeneous imaging characteristics. Differential diagnosis includes other mediastinal masses containing fat and calcifications. Surgical excision is the preferred treatment, although complete removal can be challenging due to adhesions to neighboring structures. Close follow-up is necessary to monitor for recurrence and complications. Mediastinal mature cystic teratomas are rare tumors with variable clinical presentations.
