Panniculitis with Fever of Unknown Origin

We present a case of a girl in her early childhood with a background of chromosomal deletion 10q21.2, hypothyroidism, second-degree atrioventricular block, developmental delay, gastroesophageal reflux disease, constipation and recurrent fevers. She had subcutaneous nodules, which represented panniculitis. Diagnosis of fever of unknown origin (FUO) associated with panniculitis was very challenging despite the involvement of geneticist, dermatologist, rheumatologist and paediatrician. To detect possible malignant cases and start treatment plans promptly, the case emphasises the need for a comprehensive diagnostic examination, which includes an early biopsy of nodular lesions. To maximise patient outcomes in complicated paediatric presentations, it emphasises the need for continual multidisciplinary teamwork and close monitoring. This case adds to the body of knowledge on the treatment of panniculitis and FUO in paediatric patients, highlighting the need of a comprehensive approach to treatment.
