Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Sowminya Arikapudi, M.B,B.S. [2]

Overview

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.^[1]]]

Genetics

Genes involved in the pathogenesis of primary cutaneous follicle centre lymphoma include:^[2]

Amplification of C-REL gene
BCL-2 rearrangements

Association

Primary cutaneous follicle center lymphoma (PCFCL) may be associated with:^[3]

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.^[3]

Multinodular mass on the scalp (A) and spectacular response after the second chemotherapy course (B).^[4]

Microscopic Pathology

Histopatological fingings. Biopsy of the mass of the scalp showing a dense and diffuse dermal infiltrate with nodular growth pattern (A) consisted of large atypical lymphocytes (H&E) (B), which are positive for CD20 (C) and Bcl6 (D) and negative for Bcl2 (E) on immunohistochemical staining. Bone marrow biopsy showing a hypercellular bone marrow with proliferation of megakaryocytes with hyperlobulated nuclei, sometimes in loose clusters (H&E) (F), positive for CD61 on immunohistochemical staining (G).^[4]
