Sickle-cell disease (SCD) a hereditary autosomal recessive disorder is the most common haemoglobinopathy worldwide. In India, it is the second most common haemoglobinopathy next to Thalassemia, prevalent in the tribal population of Central and Southern parts of India. The pathophysiology of the disease is point mutation in the beta globin chain leading to sickling of RBCs which causes obstruction in microvasculature leading to acute events like Vaso-occlusive crisis. Patients with SCD are also at an increase of orthopaedic manifestation like osteomyelitis, septic arthritis or osteonecrosis. We report a case of a 10 months old male child who presented with anaemia and fever. Child was diagnosed with SCD, later developed swelling of right shoulder joint and restrictions of movements. Diagnosis of septic arthritis of shoulder with scapular osteomyelitis was made with the help of radiological and laboratory investigations. Child was managed with injectable antibiotics and symptomatic treatment. Patients with SCD as a result of occlusion of microvasculature along with immunocompromised state are at higher risk of bacterial infections. Osteomyelitis is one of the dreaded complications. Its clinical presentation is similar to that of VOC hence there occurs a dilemma in diagnosis. A multidisciplinary approach including high degree of clinical suspicion, laboratory investigation and radiological imagining can help in early diagnosis and management.

Background: Subcutaneous fat necrosis of the newborn (SCFN) is a panniculitis characterized by the presence of violaceous subcutaneous nodules and indurated plaques on the back, buttocks, proximal extremities, or cheeks. It is a self-limiting benign condition sometimes associated with hypercalcemia that can lead to serious complications such as seizures, failure to thrive and renal failure. It usually develops in full term neonates who experienced some perinatal stress. The literature shows that hypercalcemia is found in nearly 51% of infants, with 95% of the infants developing it within 60 days of onset of skin  lesions. Clinical Description: In this case, we describe a full-term female infant presented to us with failure to thrive at 2 months of age with a postnatal history of meconium aspiration syndrome. On further evaluation, child was found to have hypercalcemia, anemia and bilateral nephrocalcinosis. Management & Outcome: The clinical findings and lab investigations were consistent with subcutaneous fat necrosis with hypercalcemia as its main complication. Child was successfully treated with oral corticosteroids. Conclusion: Being a rare clinical condition, it is important to consider it as a differential diagnosis in infants with significant perinatal stress and hence this case report.
