Pulmonary Lymphomatoid Granulomatosis: Report of A Case and Review of Literature.

Lymphomatoid granulomatosis (LYG) is a rare angiocentric lymphoproliferative process predominantly affecting the lung. The diagnosis of this condition is often difficult as the physical signs, history, chest x-ray, and routine laboratory investigations are usually non-specific. Nevertheless, it is important to establish a tissue diagnosis, as this lymphoproliferative disorder can be refractory to treatment and even progress to overt lymphoma. We report a case of pulmonary LYG in a 52-year old Nigerian man of Ibo extraction treated in our centre in 2001 and followed up for a year. The difficulty in making diagnosis is highlighted and treatment modality discussed.
