Spongiotic Gingival Hyperplasia in a Child with Asperger Syndrome: a Case Report.

Background: Asperger syndrome is a type of autism spectrum disorder that may affect oral health and dental management. Spongiotic gingival hyperplasia is a rare lesion with unique clinicopathological features and unknown pathogenesis that has not been previously reported in a patient with autism spectrum disorder. The purpose of this case report is to present the first case of spongiotic gingival hyperplasia in a child with Asperger syndrome.

Methods: A 14-year-old boy with Asperger syndrome was referred for diagnosis and management of bright red granular overgrowths of the marginal gingiva and interdental papilla of the mandibular right incisors and marginal gingiva of the mandibular left incisor. A biopsy was performed on the interdental papilla between the mandibular right incisors.

Results: Microscopic examination and cytokeratin 19 immunopositivity confirmed the diagnosis of spongiotic gingival hyperplasia. The parents of the patient declined any further intervention, and four months later the gingival lesions, including the biopsied area, did not show any significant difference from the initial examination.

Conclusions: Patients with autism spectrum diseases, such as Asperger syndrome, cannot achieve a good level of oral hygiene. Thus, it is expected that the incidence of spongiotic gingival hyperplasia should be higher in this group of patients, in case oral microbiome participates in its pathogenesis. Management of such lesions is challenging, as such patients do not comply with a proper oral hygiene program and do not cooperate with surgical excision.
