Overview
Primary cutaneous follicle center lymphoma is a tumor of neoplastic follicle centre cells, including centrocytes and variable numbers of centroblasts, with a follicular and diffuse growth pattern that generally presents on the head or trunk. This is the most common type of primary cutaneous B-cell lymphoma.[1] Primary cutaneous follicle center lymphoma (PCFCL) may be associated with borrelia burgdorferi, hepatitis C, and human herpesvirus 8. On gross pathology,solitary or grouped erythematous papules, plaques and tumor lesions, mostly non-ulcerated are characteristic findings of primary cutaneous follicle center lymphoma. On microscopic histopathological analysis, centroblasts (large noncleaved cells), centrocytes (small and large cleaved cells), and reactive T cells are characteristic findings of primary cutaneous follicle center lymphoma.[2]
Pathophysiology
Primary cutaneous follicle center lymphoma (PCFCL) is characterized by a proliferation of follicle center cells (centrocytes and centroblasts) with a follicular, follicular and diffuse, or diffuse growth pattern.[3]
Genetics
Genes involved in the pathogenesis of primary cutaneous follicle centre lymphoma include:[1]
- Amplification of C-REL gene
- BCL-2 rearrangements
Association
Primary cutaneous follicle center lymphoma (PCFCL) may be associated with:[2]
Gross Pathology
On gross pathology, solitary or grouped erythematous papules, plaques and tumor lesions, mostly non-ulcerated are characteristic findings of primary cutaneous follicle center lymphoma.[2]

 |
 |
Microscopic Pathology
On microscopic histopathological analysis, centroblasts (large noncleaved cells), centrocytes (small and large cleaved cells), and reactive T cells are characteristic findings of primary cutaneous follicle center lymphoma.[2]
