Key result
Excisional biopsy of pediatric oral epithelioid hemangioendothelioma demonstrates multiple local recurrences over 4.5 years.
Case Report (n=1)
This case report describes a rare presentation of epithelioid hemangioendothelioma in the oral cavity of a child.
May warrant extended surveillance after excision in pediatric oral cases; single report leaves optimal management open.
Epithelioid hemangioendothelioma is a rare vascular neoplasm which exhibits the potential for malignancy and recurrence as well as the ability to metastasize. Although numerous sites of involvement are possible, these tumors most commonly arise in soft tissues, lung, liver, bone, and lymph nodes. In this report, we describe a case of oral epithelioid hemangioendothelioma in a child. This tumor appeared as exophytic ulcerated painless masses in the maxillary and mandibular gingiva. Histologically, the tumor was composed of a proliferation of tumor cells arranged in nests, cords, and short strands. Epithelioid cells exhibited abundant eosinophilic cytoplasm with nuclear and cellular pleomorphism and intra-cytoplasmic vacuoles.

Mohtasham et al. (2008) conducted a case report in Epithelioid hemangioendothelioma of the oral cavity (n=1). Excisional biopsy was evaluated on Recurrence and histopathological diagnosis. Excisional biopsy of an oral epithelioid hemangioendothelioma in a 9-year-old boy was followed by multiple local recurrences over a 4.5-year period, highlighting the tumor's potential for recurrence.
