Sinonasal Lobular Capillary Hemangioma After Continuous Self-tests for COVID-19: A Case Report and Review of the Literature

Abstract

Sinonasal lobular capillary hemangiomas (LCH) are rare benign vascular lesions commonly arising from the nasal septum. Nasopharyngeal, nasal mid-turbinate, and anterior nasal swabbing is the preferred method of screening for coronavirus disease-2019 (COVID-19). Herein, we present a case of a sinonasal LCH in a child after continuous self-tests for COVID-19, with an anterior nasal swab. The child presented with a well-defined red mass in the anterior part of the nasal septum, which was removed endoscopically. Histopathology revealed a LCH. This is the first report of a complication other than epistaxis with the use of an anterior nasal swab. Our literature review identified 32 studies reporting complications of COVID-19 screening. Cerebrospinal fluid leaks and foreign body retention are the most common ones. A proper specimen collection technique and a quick patient history with an emphasis on risk factors are the best practices to prevent complications from COVID-19 screening.

“…Histologically, lobular capillary hemangioma reveals lobular vascular proliferation consisting of vessels of capillary caliber. 8 On the other hand, inverted papilloma is mucosal origin with cere-briform, lobulated, and firm appearance. 6,9 In contrast to GPC, inverted papilloma shows male predominance with a 2 to 3:1 male: female ratio and usually arises from maxillary sinus and lateral nasal wall.…”

“…However, it is still difficult to distinguish between these lesions because they usually present with a solid and soft texture. Histologically, lobular capillary hemangioma reveals lobular vascular proliferation consisting of vessels of capillary caliber .
