Oral Involvements of Hypersensitivity Reactions to ChemotherapyDrugs in Immunocompromised Child Patient: A Case Report
<p class="AbstractContent"><strong>Background:</strong> Hypersensitivity reactions (HSRs) may occur in children with cancer during the use of almost all chemotherapeutic drugs, commonly present with mild/moderate to severe clinical patterns.</p><p class="AbstractContent"><strong>Case report:</strong> A 7-year-old, male patient, was referred from the RSUP Hasan Sadikin Pediatric Department, with the diagnosis of Acute Lymphocytic Leukemia (ALL), acute otitis media and Toxic Epidermal Necrolysis (TEN) ec susp/ metrotreksat ec susp/ leucovorine. The patient was diagnosed with oral involvement related to anemia and TEN. Lesions of reddish black crusts manifested on upper and lower lips, and multiple red macules in labial and buccal mucosas. Oral lesions showed significant improvement after administration of comprehensive treatment including corticosteroid mixed ointment, antimitotic oral suspension and multivitamin.</p><p class="AbstractContent"><strong>Discussion:</strong> The mechanisms responsible for most HSRs, including drug-related are not known, as they have generally not been evaluated. Most reactions are of the type I category in the Gell and Coombs classification, but there also are instances of types II, III, and IV reactions caused by many of the antineoplastic agents. Oral involvements in children due to hypersensitivity reactions are likely to occurred because they are more susceptible to stomatotoxic effects of chemotherapeutic agents, possibly related to a higher epithelial mitotic rate.</p><strong>Conclusion:</strong> Knowledge of the different clinical presentations of chemotherapeutic agent’s hypersensitivity reactions ‘oral involvements can help to ensure a good treatment outcome, to improve the quality of patient care and to reduce healthcare costs.
