Follicular Lymphoma in Companion Animals

Lymphoma is an enigmatic and fascinating disease complex that involves almost all vertebrates and can be of B, T, or NK cell of origin. More than 70% of canine lymphomas are of B cell origin. Since the discovery of Hodgkin’s lymphoma by an anatomist Thomas Hodgkin in 1832, all malignant lymphomas in humans were characterized as either Hodgkin lymphoma or non-Hodgkin lymphoma at the beginning of the twenty-first century [2]. Follicular lymphomas (FL) are the common subtype of non-Hodgkin lymphoma in humans and are associated with an indolent i.e, slowly progressive biological behavior in early stages.
