Carcinoid tumour in the lacrimal gland

Abstract

A case of carcinoid tumour in the lacrimal gland is described, thought to be a metastasis from a known primary lesion in the mediastinum. The results of light and transmission electron microscopic examination are presented, and the possibility of the lesion representing a second primary tumour discussed.

Lacrimal Gland Intravascular Micrometastasis From a Human Papillomavirus-Driven Anorectal Squamous Cell Carcinoma With a Review of Metastatic Disease to the Lacrimal Gland

“…To the authors' knowledge, only 24 cases have been described. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Herein, the authors review lacrimal gland metastatic disease and describe the first known case from a primary anorectal SCC. In this patient with human immunodeficiency virus, an HPV-driven tumor hematogenously spread to the lacrimal gland in the form of diffuse intravascular tumor deposits that did not erupt in the lacrimal parenchyma to create a discrete mass lesion.…”
