Spindle Cell Hemangioendothelioma of the Temporal Muscle Resected with Zygomatic Osteotomy: A Case Report of an Unusual Intramuscular Lesion Mimicking Sarcoma

Abstract

Spindle cell hemangioendothelioma (SCH) was originally described by Weiss and Enzinger (1986) as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities. Few reports describe SCH of the head and neck region; even fewer note intramuscular SCH. Here, we describe a case of SCH involving the temporal muscle mimicking soft tissue sarcoma, who had a successful surgical treatment with a coronal approach and zygomatic osteotomy.

Successful outcome after intralesional curettage for spindle cell hemangioma of fibula: a case report

“…It also can be associated with several clinical syndromes, among which Maffucci syndrome is the most common [8,9]. In several uncommon cases, SCHs have been found in lips, nasal passage, temporal muscle, and even in lungs and spleen [2,[10][11][12][13]. In comparison, the reported cases of SCH arising in bones are even more unusual so far [14][15][16].…”

“…It also can be associated with several clinical syndromes, among which Maffucci syndrome is the most common (8,9). In several uncommon cases, SCHs have been found in lips, nasal passage, temporal muscle, and even in lungs and spleen (2,(10)(11)(12)(13). In comparison, the reported cases of SCH arising in bones are even more unusual so far (14-16).…”

Spindle Cell Hemangioma of the Nasal Cavity: A Rare Tumor with Unusual Presentation

“…5 As per our knowledge, only 10 cases of SCH have been reported in the head and neck region, six in the soft tissue and lip, three in the oral cavity and one in the temporal muscle. [1][2][3] Till date, no case of SCH occurring in the nasal cavity or middle turbinate has been reported.…”

“…Very few cases of SCH have been reported in the soft tissue of head and neck, oral cavity and in the temporal muscle. [1][2][3] Extensive literature search did not reveal any case of SCH occurring in the nasal cavity, reported till now. It is important to recognize these lesions, since they have high rate of recurrence, and metastatic potential of the tumor is still debatable.…”
