To describe a case of an intravascular lobular capillary hemangioma arising in the temporal artery of an older patient.
Lobular capillary hemangiomas (LCHs) are common benign vascular tumors previously described in literature as arising in the skin and mucous membranes of children and young adults. They have very rarely been characterized as arising from the temporal artery or being present in older adults. This report details the case of a 60-year-old man with reported history of intermittent blurry vision and jaw pain, headaches, and fatigue with bilateral shoulder and neck pain. He subsequently developed a palpable, tender left temple mass over the course of three weeks. Ultrasound of the left forehead over the lesion identified focal outpouching of a blood vessel with a thickened wall and arterial flow. Biopsy of the lesion, initially intended to rule out vasculitis, demonstrated numerous capillaries amidst a fibromyxoid stroma with immunohistochemical staining confirming it as an LCH. The first reported case of an intravascular lobular capillary hemangioma (IVLCH) of the temporal artery involved a 27-year-old man in 1994; this was, followed by a second report of a 47-year-old man in 2022, both of which were confirmed via biopsy. .
This is a reported case of a temporal artery IVLCH in an older patient. This contributes to limited literature characterizing unusual IVLCH variants, and while rare, can be considered in the differential for temporal artery pathology and superficial temporal masses.
描述一例发生于老年患者颞动脉的血管内小叶状毛细血管瘤。
小叶状毛细血管瘤（LCHs）是常见的良性血管肿瘤，此前文献报道其发生于儿童和青年的皮肤及黏膜。它们极少被描述为起源于颞动脉或见于老年人。本报告详细介绍了一名60岁男性的病例，该患者有间歇性视力模糊、颌部疼痛、头痛以及双侧肩部和颈部疼痛伴疲劳的病史。随后，在三周内他左侧颞部出现了一个可触及的压痛性肿块。对病变上方左侧前额进行超声检查，发现一处血管局灶性膨出，血管壁增厚且有动脉血流。对病变进行活检，最初旨在排除血管炎，结果显示在纤维黏液样基质中有大量毛细血管，免疫组化染色证实为LCH。1994年首次报道了一例发生于颞动脉的血管内小叶状毛细血管瘤（IVLCH），患者为一名27岁男性；随后在2022年又报道了一例47岁男性的病例，两例均经活检确诊。
本文报道了一例老年患者颞动脉IVLCH病例。这为描述不寻常IVLCH变体的有限文献增添了内容，虽然罕见，但在颞动脉病变和颞浅肿块的鉴别诊断中可予以考虑。
