Oral Manifestation of Lymphomatoid Granulomatosis
Lymphomatoid granulomatosis (LYG) is a rare B-cell lymphoproliferative disorder driven by Esptein–Barr virus (EBV) that most commonly affects the lungs, although extra pulmonary sites like the central nervous system, skin, liver and kidney can also be involved. It is microscopically characterized by an angiocentric and angiodestructive growth pattern, predominantly composed by small T-cells, although a smaller population of atypical large B-cells is considered the true neoplastic component. Oral cavity involvement of LYG has rarely been described and the diagnosis of this neoplasm is very difficult. The aim of this report is to present a rare case of LYG affecting an 86-year-old female patient that was diagnosed due to an extensive, ulcerated and painful oral lesion affecting the hard palate. Detailed microscopic evaluation together with a large immunohistochemical study were necessary to achieve the correct diagnosis of LYG.
