Key result
Superficial parotidectomy and wide excision reveal masseter muscle epithelioid angiosarcoma in a 15-year-old boy.
Why the study?
Epithelioid angiosarcoma is a rare subtype of endothelial angiosarcoma, with no prior case reports documenting its occurrence in the masseter muscle.
Case Report (n=1)
This represents the first reported case of epithelioid angiosarcoma occurring in the masseter muscle.

First reported masseter epithelioid angiosarcoma in an adolescent; extends parotid mass differential but leaves optimal management unresolved.
Epithelioid angiosarcoma (EA) is a subtype of angiosarcoma which is a rare tumor of endothelial origin. Here, we report a case of 15-year-old boy who presented with soft tissue mass lesion in the parotid region mimicking as a benign parotid tumor. Cytology was suggestive of inflammatory swelling. Patient underwent superficial parotidectomy along with the wide excision of the swelling. On histopathology, it was diagnosed as EA. To the best of our knowledge this is the first case report of epithelioid angiosarcoma of the masseter.

Srivastava et al. (2020) conducted a case report in Epithelioid angiosarcoma of the masseter muscle (n=1). Superficial parotidectomy and wide excision was evaluated on Histopathological diagnosis. Superficial parotidectomy and wide excision of a parotid region mass in a 15-year-old boy revealed epithelioid angiosarcoma of the masseter muscle on histopathology.
