Lingual ASPS is a tumour of childhood with a distinctive, predominantly solid growth pattern. Despite typical vascular invasion, the early diagnosis and small tumour size may explain its relatively good outcome.

Angiosarcomas of the oral and salivary gland area are extremely rare, mostly presented as case reports. We wanted to study the clinicopathologic features of a series of oral and salivary gland angiosarcomas. Cases coded as "angiosarcoma" were retrieved from the Oral and Maxillofacial Pathology Department of the Armed Forces Institute of Pathology. Patient folders and pathology were reviewed and recorded; immunohistochemistry and follow-up were obtained. Inclusion required oral or salivary gland location, vasoformative growth, cytologic atypia, mitoses, and vascular markers. Skin, bone, and subcutaneous angiosarcomas were excluded. Primary and secondary (metastatic) oral angiosarcomas were included. The 22 primary angiosarcomas involved tongue (n ‫؍‬ 9), parotid (n ‫؍‬ 4), lip (n ‫؍‬ 4), submandibular gland (n ‫؍‬ 3), and 1 each of soft and hard palate. The 7 secondary angiosarcomas involved the gingiva (n ‫؍‬ 4) and parotid gland (n ‫؍‬ 3). Overall, patient ages ranged from 6 -90 years (mean, 55 years). There were 15 males and 14 females. Symptoms included a mass with recent enlargement and bleeding. Tumor sizes ranged from 0.8 -7.0 cm (mean, 2.6 cm). Histologically, all tumors were vasoformative; 86% had solid and 17% had distinctive papillary areas. Eight (28%) were classified as the epithelioid subtype. Immuno
