BACKGROUND: Nonmycosis fungoides/Sézary syndrome (non-MF/SS) primary cutaneous lymphomas (PCL) are currently categorized under the 2005-World Health Organization/European Organization for Research and Treatment of Cancer (WHO-EORTC) classification for PCL. These differ in behavior from secondary cutaneous lymphomas (SCL) and to lymphomas limited to the oral cavity (primary oral lymphomas [POL]) both categorized under the 2016-WHO classification for lymphoid neoplasms. AIMS: This study aims to report the first series of non-MF/SS PCL, SCL, and POL in a Mexican cohort, examine the applicability of current classification systems and compare our findings with those from foreign cohorts...

Primary cutaneous spindle cell lymphoma is a rare variant of primary cutaneous B-cell lymphoma (PCBCL). Herein, we present 3 cases of primary cutaneous spindle cell B cell lymphoma, 2 males and one female (age range 66-76years). The patients presented with solitary skin lesions, distributed in the head and neck area and chest. The dominant cell size was in the intermediate to large cell size range. While the main cell type was a spindled one, other cells with a nuclear morphology quite typical for a centroblast were noted and as well careful inspection in the three cases revealed a focal residuum of germinal center-like structures...

BACKGROUND AND OBJECTIVES: Intralesional injection of anti-CD20 antibody (rituximab) has been described as effective therapeutic option for patients with indolent primary cutaneous B-cell lymphoma (PCBL). To date, no parameters that reproducibly predict favorable clinical outcome of this treatment have been identified. The study aims to evaluate the clinical response and adverse effects as well as patients' self-perception of intralesional injection of anti-CD20 antibody for treatment of indolent PCBL compared to other treatment modalities...

Cutaneous B-cell lymphomas (CBCLs) comprise a group of mature lymphoproliferative B-cell disorders that primarily affect the skin. Characterized by great biological and clinical variability among its various subtypes, CBCLs fundamentally differ from primary nodal or systemic B-cell lymphomas. Given their uncomplicated course and excellent prognosis, lymphoma classifications rank primary cutaneous marginal zone lymphoma (PCMZL) and primary cutaneous follicle center lymphoma (PCFCL) as indolent CBCLs. By contrast, diffuse large B-cell lymphoma, leg type (DLBCL-LT) in particular, represent more aggressive lymphoma variants associated with a poorer prognosis...

Diffuse large cell B-cell lymphoma of the skin is most commonly represented by diffuse large cell variants of primary cutaneous follicle center lymphoma and the leg-type lymphoma. In a minority of cases, the infiltrates are an expression of stage 4 disease of established extracutaneous B-cell lymphoma. We describe 1 female patient 85 years of age with an aggressive form of primary cutaneous B-cell lymphoma manifesting in multiple firm erythematous indurated solid nodules 1-2 cm each symmetrically on the face periorbitally and on the upper extremities bilaterally...

DISEASE OVERVIEW: Approximately one-fourth of cutaneous lymphomas are B-cell derived and are generally classified into three distinct subgroups: primary cutaneous follicle center lymphoma (PCFCL), primary cutaneous marginal zone lymphoma (PCMZL), and primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT). DIAGNOSIS: Diagnosis and disease classification is based on histologic review and immunohistochemical staining of an appropriate skin biopsy. Pathologic review and an appropriate staging evaluation are necessary to distinguish primary cutaneous B-cell lymphomas from systemic B-cell lymphomas with secondary skin involvement...

BACKGROUND: Primary cutaneous follicle center lymphoma (pcFCL) usually presents with reddish nodules, plaques, and tumors on the head and neck or the back. OBJECTIVE: We sought to describe a peculiar clinical presentation of pcFCL and secondary cutaneous follicle center lymphoma (FCL). METHODS: We report a series of 13 patients (7 male and 6 female; median age 58 years, mean age 58.2 years, age range 26-83 years) with either pcFCL (11 patients) or secondary cutaneous FCL (2 patients) presenting with lesions on the head deviating from the classic clinical manifestations characterized by plaques and tumors...

Thymocyte selection-associated high-mobility group box (TOX) is aberrantly expressed in cutaneous T-cell lymphomas. In a recent study, TOX expression was noted unexpectedly in the follicle center (germinal center) B-cells of reactive lymph nodes and tonsils, used as external controls. To evaluate whether TOX is also expressed by cutaneous B-cell lymphomas, TOX immunohistochemistry was performed on skin biopsies of 44 patients with primary and secondary cutaneous B-cell proliferations. TOX was expressed not only in the reactive follicle center cells of lymph nodes, tonsils, cutaneous lymphoid hyperplasia, and primary cutaneous marginal zone lymphomas, but also by the neoplastic follicle center cells of 16/17 patients with primary cutaneous follicle center lymphoma (PCFCL) and 7/7 patients with cutaneous manifestations of systemic follicular lymphoma (FL)...

Primary cutaneous follicle center lymphoma (PCFCL) is a common subtype of primary cutaneous B-cell lymphoma (PCBCL). The prognosis of this subtype is favorable and recurrence is observed in up to 50% of patients. The dissemination to lymph nodes or internal organs is rare. In this study, two cases of rare variant of PCFCL are reported. Both cases presented with multiple erythematous nodules, plaques and some annular configurations. Histopathological examination revealed dermal lymphocytic infiltrates consisting of admixed centrocytes and centroblasts...

The classification of cutaneous follicular lymphoma (CFL) into primary cutaneous follicle center lymphoma (PCFCL) or secondary cutaneous follicular lymphoma (SCFL) is challenging. SCFL is suspected when tumor cells express BCL2 protein, reflecting a BCL2 translocation. However, BCL2 expression is difficult to assess in CFLs because of numerous BCL2+ reactive T cells. To investigate these issues and to further characterize PCFCL, we studied a series of 25 CFLs without any extracutaneous disease at diagnosis, selected on the basis of BCL2 protein expression using 2 BCL2 antibodies (clones 124 and E17) and BOB1/BCL2 double immunostaining...

Primary cutaneous B-cell lymphomas are a heterogeneous group of mature B-cells neoplasms with tropism for the skin, whose biology and clinical course differ significantly from the equivalent nodal lymphomas. The most indolent forms comprise the primary cutaneous marginal zone and follicle center B-cell lymphomas that despite the excellent prognosis have cutaneous recurrences very commonly. The most aggressive forms include the primary cutaneous large B-cell lymphomas, consisting in two major groups: the leg type, with poor prognosis, and others, the latter representing a heterogeneous group of lymphomas from which specific entities are supposed to be individualized over time, such as intravascular large B-cell lymphomas...

Primary cutaneous lymphomas are non-Hodgkin lymphomas, which are broadly divided into cutaneous T-cell lymphomas and cutaneous B-cell lymphomas. These classifications include numerous distinct entities, all with varying clinical presentations and disease courses. Herein, we will review the cutaneous T-cell lymphomas, including Mycosis Fungoides, Sézary syndrome, CD30+ lymphoproliferative disorders, as well as other less common entities. Cutaneous B-cell lymphomas will also be discussed, including primary cutaneous marginal zoned lymphoma, cutaneous follicle-center lymphoma, diffuse large B-cell lymphoma, leg type, as well as other less common entities...

Primary cutaneous B-cell lymphomas (PCBCLs) constitute 25% of all primary cutaneous lymphomas. They present in the skin with no evidence of systemic or extracutaneous disease at the time of diagnosis, after adequate staging. Primary cutaneous B-cell lymphomas differ significantly from their nodal counterparts in relation to both clinical behavior and prognosis. The distinction between primary and secondary B-cell lymphomas is essential for defining prognosis/course of action. Such distinction is also very difficult to make, since primary and secondary B-cell lymphomas are clinically and histologically indistinguishable...

BACKGROUND: The increasing incidence of primary cutaneous B-cell lymphomas (PCBCLs) presents new challenges for clinicians. Despite advances in the clinical and pathologic characterization of PCBCL, the significance of the current staging approach as a risk profiling tool and the effect of various treatments on outcome remain unclear. MATERIALS AND METHODS: We retrospectively reviewed patients who presented with a diagnosis of PCBCL seen at The Ohio State University between 1998 and 2012...

OBJECTIVES: To study the diagnostic value of BCL2 rearrangement in follicle center lymphoma (FCL) presenting as primary skin lesions, evaluate its prevalence and the prognostic value in primary cutaneous FCL (PCFCL), and assess prognostic factors in PCFCL. METHODS: Fifty-three patients with a cutaneous presentation of FCL without a history of nodal lymphoma were selected retrospectively. Clinical and histologic data were collected together with staging and follow-up data...

Cutaneous lymphomas of both B cells and less commonly T cells can exceptionally exhibit spindle-cell morphology. Less than 30 spindle-cell B-cell lymphomas of the skin have been described, mostly before the adoption of detailed immunohistochemistry, and thus initially interpreted as variants of diffuse large B-cell lymphoma (DLBCL). Furthermore, some authors suggest that cutaneous spindle-cell B-cell lymphomas (cSCBCLs) may behave more aggressively than their conventional morphologic counterparts and may thus merit more aggressive treatment...

The oncogenic microRNA (miR) 17-92 cluster has a causative role in the lymphomagenesis of nodal B-cell lymphomas, by activating proliferation and inhibiting apoptosis. Here we analyzed primary cutaneous B-cell lymphomas for the miR-17-92 cluster and its paralogs miR-106a-363 and miR-106b-25. In 22 primary cutaneous diffuse large B-cell lymphomas, leg type (PCLBCL-LT) compared with 22 primary cutaneous follicle center lymphomas (PCFCLs), we found that miR-20a and miR-106a were overexpressed. Multivariate Cox analysis showed that higher miR-20a and miR-20b expression levels were associated with shorter disease-free and overall survival, independently from histological type...

Clinical features and treatment outcomes of primary cutaneous B-cell lymphoma (PCBCL) have rarely been reviewed, due to the rarity and pathologic obscurity of this disease. We reviewed 21 patients who were pathologically diagnosed with PCBCL from Samsung Medical Center's lymphoma cohort, following the WHO-EORTC classification system: primary cutaneous follicle-center lymphoma (PCFCL), primary cutaneous marginal zone lymphoma (PCMZL), primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL, LT), and cutaneous diffuse large B-cell lymphoma, other (PCDLBCL, other)...
