Abstract

An unusual clinical presentation of any pathology prompts a diagnostic dilemma, which further brings challenges in treatment planning. Pyogenic granuloma (microscopically lobular capillary haemangioma) is a benign vascular tumour that commonly involves the skin and mucous membranes and usually manifests as a solitary papule with a friable pedunculated base. Rapid exophytic growth and an ulcerated surface with bleeding on provocation are characteristic, with a gingival predominance for the site. This case report aims to elaborate on an unusual clinical presentation of oral pyogenic granuloma in a middle-childhood female patient. The clinical and radiographic characteristics of the lesion were unremarkable to the diagnosis but rather mimicked other intraoral lesions. It is histopathology that could solve the puzzle with the microscopic and immunohistochemical findings that rendered the final diagnosis of lobular capillary haemangioma.
