Glomus Tumor (Glomangioma) of Eyelid

Case Report: The first case of primary pulmonary collision tumor comprising mixed squamous cell and glandular papilloma and glomus tumor

A collision tumor is a rare entity, particularly if occurring in the lung. We report a case of a 57-year-old woman with a primary pulmonary collision tumor comprising mixed squamous cell and glandular papilloma (MSGP) and glomus tumor (GT). An abnormal mass was discovered in the right lung by computed tomography (CT) of the chest. A right lower lobectomy with mediastinal lymph node dissection was performed. Histological examination of the surgical specimen suggested that the lung cancer was composed of two neoplastic components. To the best of our knowledge, this is the first report of a primary pulmonary collision tumor comprising two benign tumors of different origins, which were MSGP and GT.

Orbital-conjunctival glomangiomas involving two ocular rectus muscles

PURPOSE

To report two glomangiomas in one orbit, each isolated to a rectus muscle.

DESIGN

Clinicopathologic correlation.

METHODS

A 12-year-old boy developed two separate vascular tumors, near the insertions of the medial rectus and superior rectus muscles, respectively. A biopsy of one tumor was studied by light microscopy and immunohistochemistry.

RESULTS

Histopathology revealed blood vessels surrounded by cuboidal cells characteristic of glomangioma. The cells showed immunoreactivity for smooth muscle actin and vimentin, supporting the diagnosis.

CONCLUSIONS

Glomangioma can involve the rectus muscles in the conjunctiva and orbit, and should be considered in differential diagnosis of vascular tumors in the ocular region.

Glomus cell tumor of the eyelid

BACKGROUND/METHODS

Glomus cell tumor, a vascular neoplasm, has been rarely reported to occur in the eyelid. The authors examined the clinicopathologic features of two patients with glomus cell tumor of the eyelid.

RESULTS

The tumors occurred as enlarging violaceous to bluish masses. One patient had a solitary eyelid tumor that contained sheets of individual glomus cells. The other patient had eyelid and wrist tumors and multiple family members with similar lesions.

CONCLUSION

This report provides clinicopathologic evidence that glomus cell tumor can occur in the eyelid in two different settings; in one setting, the tumor is solitary and sporadic, and in the second setting, it is multiple and familial.

Intraoral solitary glomus tumor (glomangioma): case report and literature review

The glomus tumor, or glomangioma, is a benign neoplasm arising from the normal glomus. Glomus tumors of the oral cavity are rare, with only ten cases reported in the literature. We report the light and electron microscopic features of an additional case of glomus tumor of the lip which occurred as a solitary, painless, submucosal mass in a 51-year-old woman. Clinical, diagnostic, and histogenetic aspects are discussed.
