Abstract
INTRODUCTION
Epidermoid cysts (EC) are benign and slow growing lesions. A primary brain lymphoma development related to a EC is presented, second case described in literature.
CASE PRESENTATION
A woman 40 years old, harbouring a EC for more than 20 years, develops a fast growing brain lesion next to the EC. Surgery was performed and diagnosis was primary diffuse B cells lymphoma.
DISCUSSION
Malignant transformation of EC has been described, usually to squamous cells carcinoma, and much less frequently, to another tumours. Inflammatory mechanisms have been advocated to explain this evolution. Chronic inflammation and lymphoma genesis are related, and this could be the mechanism behind this rare evolution of an EC.
CONCLUSIONS
Even being benign lesions, EC can develop malignant tumours due to the chronic inflammation secondary to them.
