langerhans cell histiocytosis of the mandible
Description
● Case Example:
The left cheek of a 4-year-old child is uncomfortably swollen.
● Clinical examination:
• Diffuse left mandibular oedema;
• Pliable and painful submandibular lymph nodes;
• Limited mouth opening (trismus, ~20 mm);
• No oral abnormalities
● Imaging Findings:
• CT: Osteolysis, periosteal reaction, and cortical rupture in the left mandibular ramus.
• MRI (contrast-enhanced T1): A mass expanding outside the bone and inflammatory oedema.
Bone scintigraphy: aberrant uptake of the mandible.
• PET-CT: FDG uptake is limited to the mandible (SUVmax 4.9).
• Differentiators include myeloma, lymphoma, plasmacytoma, LCH, and ameloblastoma.
● Histopathology & Biopsy:
Granulation-like tissue and brown exudate are seen in incisional biopsies.
● Microscopy:
Proliferation of Langerhans cells with "coffee-bean" nuclei
IHC: Positive for S-100 and CD1a; capillary hyperplasia, necrosis, bleeding, and eosinophil infiltration.
● Diagnosis: Mandibular single-system (SS) type LCH.
Protocol
● Management:
• Surgery was first considered but eventually refused because of problems with jaw growth and teeth development.
• Because spontaneous relapse in SS-type bone LCH is probable, the cautious follow-up approach was employed.
● Nursing Strategies:
• A multidisciplinary strategy that included ongoing nursing care and cutting-edge medical procedures was used to handle the issues:
• Mechanical circulatory support to stabilise circulation and facilitate cardiac and respiratory recovery (e.g., Impella devices, venoarterial extracorporeal membrane oxygenation).
• When poisoning occurs, aggressive supportive treatment is provided, which includes correcting metabolic abnormalities, gastrointestinal lavage with neutralising medicines (such as coconut oil for aluminium phosphide poisoning), and early hospitalisation.
• Immunosuppressive treatment, complication monitoring, and rehabilitation may be required for vascular and autoimmune disorders.
• In every case, regular reevaluation and modification in response to changing clinical state were essential.
● Haemodynamic Monitoring and Support:
• Constant observation of vital signs, including oxygen saturation, heart rate, blood pressure, and respiration rate
• Prompt detection and treatment of arrhythmias, shock, and device-related issues.
● Device Maintenance and Surveillance:
•Frequent assessment of mechanical support devices (ECMO cannulas, ECPELLA, and Impella); sterile equipment upkeep to prevent infections; and monitoring for limb ischaemia and pressure injuries after device insertion.
● Prevention of Skin Infections:
• Regular skin examination to prevent deterioration and pressure ulcers strict adherence to infection prevention protocols, such as aseptic technique, daily wound care, and line and catheter management.
● Care for the Respiratory System:
• Monitoring for respiratory failure and putting a ventilator in place if needed
• Suctioning secretions and maintaining airways in intubated patients, encouraging deep breathing and, once stable, mobility.
● Support for Nutrition and Hydration:
assessing nutritional status, developing individualised meal plans in collaboration with nutritionists, promoting oral or enteral eating, monitoring intake and output, and maintaining enough water.
