“…After a detailed examination of these studies, 49 papers were excluded from our review because they reported localizations other than head and neck or cases of metastatic tumors, or they had no data available. Patients’ demographics are reported in Table 1 [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ]. The 34 published studies of this literature review include a total of 231 patients, 106 males (46%) and 124 females (54%), 1 patient not specified (0.4%), with a male/female ratio of 85% (106/124).…”

Meningiomas represent the most common benign histological tumor of the central nervous system. Usually, meningiomas are intracranial, showing a typical dural tail sign on brain MRI with Gadolinium, but occasionally they can infiltrate the skull or be sited extracranially. We present a systematic review of the literature on extracranial meningiomas of the head and neck, along with an emblematic case of primary extracranial meningioma (PEM), which provides further insights into PEM management. A literature search according to the PRISMA statement was conducted from 1979 to June 2021 using PubMed, Web of Science, Google Scholar, and Scopus databases, searching for relevant Mesh terms (primary extracranial meningioma) AND (head OR neck). Data for all patients were recorded when available, including age, sex, localization, histological grading, treatment, possible recurrence, and outcome. A total of 83 published studies were identified through PubMed, Google Scholar, and Scopus databases, together with additional references list searches from 1979 to date. A total of 49 papers were excluded, and 34 manuscripts were considered for this systematic review, including 213 patients. We also reported a case of a 45-year-old male with an extracranial neck psammomatous meningioma with sizes of 4 cm × 3 cm × 2 cm. Furthermore, whole-body 68Ga-DOTATOC PET/CT was performed, excluding tumor spread to other areas. Surgical resection of the tumor was accomplished, as well as skin flap reconstruction, obtaining radical removal and satisfying wound healing. PEMs could suggest an infiltrative and aggressive behavior, which has never found a histopathological correlation with a malignancy (low Ki-67, <5%). Whole-body 68Ga-DOTATOC PET/CT should be considered in the patient’s global assessment. Surgical removal is a resolutive treatment, and the examination of frozen sections can confirm the benignity of the lesion, reducing the extension of the removal of healthy tissue surrounding the tumor.

Primary ectopic meningiomas, although widely reported in multiple sites of the body, are particularly rare in the pleura. Here, we report a 35-year-old asymptomatic woman who was found to have a large mass in the right pleural area on physical examination chest radiography. Chest CT scan showed a large irregular mass from the right second anterior costal pleura to the right supradiaphragm, in which calcified plaques of varying sizes were widely and heterogeneously distributed. The mass was connected to the pleura (anterior rib pleura, mediastinal pleura, diaphragmatic pleura) in a wide base, with oblique “Z” changes in the coronal view. After the contrast agent injection, the mass exhibited mild enhancement on both arterial and venous phase scans. Furthermore, a linear enhancement that was indicative of “pleural tail sign” changes in the pleura adjacent to the mass was observed. The disease was preoperatively misdiagnosed as malignant pleural mesothelioma, and the postoperative pathological diagnosis was right pleural meningioma (gritty type). Therefore, we carefully analyzed its imaging features and differential diagnosis by consulting relevant literature.

“…Ectopic meningiomas are also reported in oral cavity [20,21]. Despite the similarity of histopathologic and immunohistochemical features to the hamartoma, the hamartomas distinguish themselves by limited growth potential, poorly defined borders, and the meningothelial elements intermingle haphazardly within the collagen.…”

Choristomas and hamartomas within the oral cavity are relatively uncommon lesions and may present with diverse clinical and histopathological appearances. In this report, we describe two infant patients with hamartoma with ectopic meningothelial elements involving tongue and maxillary alveolar ridge. To the best of our knowledge, these are the first two cases in which a meningothelial proliferation has been identified in the oral cavity. Hamartoma with ectopic meningothelial elements is a rare condition that has been classically described occurring in the scalp. These lesions are characterized by bland round to spindle-shape cells that interdigitate through collagen bundles and express progesterone receptor and epithelial membrane antigen by immunohistochemistry supporting a meningothelial origin.
