Introduction Down syndrome is a congenital genetic disorder caused by an error in cell division, resulting in the presence of an additional third chromosome 21. Down syndrome is one of the leading causes of intellectual disability. Millions of these patients face various health issues. This study aimed to provide information about the challenges in the management of chronic ulcer mimicking OSCC in Down Syndrome child with motoric disorders. Case A 12-year-old boy with Down Syndrome and motoric disorders was referred to Oral Medicine Department. In the extraoral examination, the patient had a dysmorphic face and dry lips. Lymph node examination could not be assessed because the patient wore a cervical collar. The intraoral examination showed an irregular ulcer with 1×0.7 cm in diameter, indurated margin, and white-yellowish base at the right lateral border of the tongue. The 55 teeth were sharp and caused an occlusion trauma to the right lateral border of the tongue. The patient was diagnosed with a chronic traumatic ulcer mimicking OSCC based on clinical examination. The medication given to the patient were sodium chloride 0.9%, povidone-iodine mouthwash 1%, and petroleum jelly. Conclusion Children with Down syndrome often suffer from orofacial abnormalities which can affect their oral health and their family’s quality of life. Dental and oral care for Down Syndrome children with motoric disorders required some challenges and collaboration with their parents, families, and caregivers.
Introduction: Dermatitis herpetiformis (DH) is an autoimmune vesiculobullous disease associated with celiac enteropathy. The clinical manifestation of DH is the occurrence of a papulovesicular rash on the skin. Oral mucosal involvement in DH is very rare. This study aimed to describe the impact of COVID-19 on the acute exacerbation of oral dermatitis herpetiformis. Case Report: A 74-year-old woman was referred to the Oral Medicine Department with a chief complaint of the blisters on the skin for a week and ulcers in the oral cavity appeared two days ago. Extraoral examination revealed crusts on the neck and extremities. The lips appeared dry and desquamative. Intraoral examination revealed erosive lesions covered with a white-yellowish plaques on the right and left sides of the buccal mucosa, an ulcer with a diameter of 0.5 cm, and purpura hemorrhagic on left buccal mucosa and right lateral border of the tongue. Histopathological examination of the skin lesion revealed a subepithelial blister with eosinophils and neutrophil cells. The definitive diagnosis of dermatitis herpetiformis was made. She was given 5 mg intravenous dexamethasone, cetirizine 10 mg, and clindamycin 300 mg by the dermatologist. We gave hyaluronic acid 0.025% mouthwash for oral ulcers and petroleum jelly for the lips. The oral lesions had significant improvement after 4 weeks of treatment. Two months later, the patient experienced acute exacerbation after being infected with COVID-19 (anti-SARS-CoV-2 IgG S-RBD >40,000 AU/mL). The oral lesions healed after a month of treatment. Conclusion: COVID-19 can trigger the acute exacerbation of dermatitis herpetiformis. SARS-CoV-2 causes an immune dysregulation and hypersensitivity reaction.
