Approximately 13–20% of infants with milk allergies concurrently exhibit beef allergies. Here, we report a 24-month-old infant who exhibited both pork and beef allergies, concurrently with a milk allergy. The infant's laboratory test results were: 3.73 ISU-E (ISAC standardized unit for IgE) for cow milk β-lactoglobulin, 23.8 ISU-E for casein, 12.8 ISU-E for cow milk Bos d 6 of serum albumin, and 4.85 ISU-E for cat Fel d 2. This case report summarizes an infant patient diagnosed with a meat allergy that was associated with cow's milk allergy, using ImmunoCAP ISAC®. Not only ImmunoCAP ISAC® but also immunocap can be used to diagnose milk allergy and meat allergy at the same time, immunocap testing for component antigen is rare. ImmunoCAP ISAC® is used to diagnose these allergies in our case study, as it has advantage that only 1ml of blood is needed to run various component antigen tests.

Mycoplasma pneumoniae is the most common bacterial strain causing atypical pneumonia in children and adolencents. Although it is known to cause mild symptoms, it can also cause severe pulmonary or extrapulmonary complications in rare cases. Necrotizing pneumonia (NP) is often reported as a complication of Streptococcus pneumoniae and is very rarely caused by M. pneumoniae. We report a case in which a 5-year-old boy was diagnosed with lobar pneumonia with symptoms that aggravated even with macrolide antibiotic treatment. Anti-mycoplasma pneumoniae Ig-M test yielded high values, and direct polymerase chain reaction results were also positive. NP caused by M. pneumoniae was confirmed on computed tomography. After treatment involving tosufloxacin and systemic steroid, the lesion decreased in size and improved gradually when followed-up for more than 1 year. The patient did not have any predisposing or risk factors for NP.
