Cutaneous B-cell lymphomas (CBCLs) are a heterogeneous group of diseases that can have variable presentations, prognoses, and treatments. The proper identification of a CBCL hinges on proper histopathologic and clinical evaluation. Comprising 25% to 30% of the primary cutaneous lymphomas, incident cases of CBCL are rare. Given the variable natural history of the CBCL, proper classification is critical so that patients are treated appropriately. CBCLs can be divided into 2 main groups: indolent and aggressive...

Primary cutaneous marginal zone lymphoma most commonly represents an indolent form of cutaneous B cell lymphoma. However, epidermotropic marginal zone lymphoma, blastic marginal zone lymphoma and B cell dominant variants without isotype switching can be associated with extracutaneous dissemination. The presumptive cell of origin is a post germinal center B cell with plasmacytic features. In the extracutaneous setting, however, a naïve B cell origin has been proposed for a subset of marginal zone lymphomas, notably splenic marginal zone lymphoma...

Background: It is unclear whether the established association between cutaneous melanoma (CM) and lymphoid neoplasms (LNs) differs across LN subtypes. This study quantifies risk for developing CM after specific LNs and, conversely, for developing specific LNs after CM, as well as assessing clinical impact. Methods: We identified a cohort of Caucasian adults (age 20-83 years) initially diagnosed with CM or LN, as reported to 17 US population-based cancer registries, 2000-2014...

A 73-year-old man with left parotid gland swelling over 2 months was referred to our hospital in March 201X. Purpura on the lower legs had been recurrent for >20 years. Biopsy of the parotid gland demonstrated diffuse infiltration of abnormal lymphocytes that were negative for CD10 and positive for CD19, CD20, and κ-chain. The Ki-67 positivity was <10%; lymphoepithelial lesions were observed. The patient was diagnosed with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma)...

BACKGROUND: Primary cutaneous B-cell lymphomas represent approximately 25% of primary cutaneous lymphomas. Follicular centre cell lymphomas (PCFCL) and marginal zone lymphomas (PCMZL) are the two histological subtypes that present an indolent evolution. Radiotherapy is one of the recommended treatment options with few series reported. OBJECTIVE: This study aimed to evaluate radiotherapy outcomes in term of overall survival (OS) and disease-free survival (DFS) for patients suffering from a PCMZL or PCFCL, to search for predictive factors of recurrence, and to evaluate chronic and aesthetics adverse events and patient's satisfaction...

Primary cutaneous marginal zone lymphoma (PCMZL) represents an indolent subtype of non-Hodgkin lymphoma that is clinically characterized by slowly growing skin tumors with a very low propensity for systemic dissemination. The underlying genetic basis of PCMZL has not been comprehensively elucidated. To gain deeper insight into the molecular pathogenesis of PCMZL, we performed hybridization-based panel sequencing of 38 patients with well-characterized PCMZL. In 32 of the 38 patients, we identified genetic alterations within 39 selected target genes...

Herpes zoster virus reactivation in the lumbosacral dermatomal distribution is an unusual site of manifestation and atypical in presentation than its usual sites in thoracolumbar (D3-L2) and facial (V1) dermatomes. Here, we are reporting a patient of marginal zone lymphoma who on fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography scan performed for chemotherapy response evaluation showed hypermetabolic cutaneous and subcutaneous lesions in the right vulva and posteromedial aspect of the right thigh along with ipsilateral pelvic lymph nodes involvement as an incidental finding...

Primary Cutaneous B-cell Lymphomas comprehend a group of lymphoproliferative disorders characterized by being monoclonal proliferations of B-cell primarily involving the skin. Despite being recognized as autonomous and distinct clinico-pathologic entities since the late 80s, their classification is still an ongoing matter of debate. At the moment, WHO classification recognizes three disorders: primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma and primary cutaneous diffuse large B-cell lymphoma, leg type...

Over a 2-year period, swellings of all 4 eyelid margins developed in a 32-year-old woman and was accompanied by complete loss of eyelashes. An inflammatory dermatologic condition was considered the most likely cause. A full-thickness right lower eyelid biopsy revealed a multinodular lymphoid tumor at the eyelid margin which immunophenotypically and genetically was diagnosed as an extranodal marginal zone lymphoma. The mode of presentation of the disease was considered to be most unusual, as was its B cell lineage, since the majority of primary cutaneous lymphomas are of T-cell origin...

Immunoglobulin (Ig)G4 expression was recently observed in a proportion of primary cutaneous marginal zone B-cell lymphoma (PCMZL) with plasmacytic differentiation. IgG4-related disease is characterised by polyclonal lymphoplasmacytic infiltration with IgG4 expression, storiform fibrosis and obliterative phlebitis in histopathology. Here we report three cases of common variants of PCMZL with predominant and varied IgG4 expression, suggesting there is an underlying clonal progression between these two entities...

B-cell lymphomas represent approximately 20% to 25% of primary cutaneous lymphomas. Within this group, most cases (>99%) are encompassed by 3 diagnostic entities: primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma, and primary cutaneous diffuse large B-cell lymphoma, leg type. In this article, the authors present clinical, histopathologic, immunophenotypic, and molecular features of each of these entities and briefly discuss the rarer intravascular large B-cell lymphoma.

Primary cutaneous B‑cell lymphomas are rarely encountered and represent 25% of all cutaneous lymphomas. Follicular B‑cell lymphoma and marginal zone lymphoma belong to indolent subtypes which as a rule have no systemic dissemination and, thus, a mostly unchanged life expectancy. Therefore, skin-directed treatment options such as excision or radiotherapy are usually sufficient to control the disease. In contrast, cutaneous diffuse large B‑cell lymphoma and EBV-associated B‑cell lymphomas of the skin belong to more aggressive entities which demand a systemic first-line upfront therapy with R‑CHOP...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

AIMS: Distinction between primary cutaneous follicular lymphoma (PCFL) and primary cutaneous marginal zone lymphoma (PCMZL) is challenging, as clear-cut immunophenotypical and cytogenetic criteria to segregate both entities are lacking. METHODS AND RESULTS: To characterize PCFL and PCMZL more clearly and to define criteria helpful for the differential diagnosis, we compared expression of immunohistochemical markers [LIM-only transcription factor 2 (LMO2), human germinal centre-associated lymphoma (HGAL), stathmin 1 (STMN1), activation-induced cytidine deaminase (AID), myeloid cell nuclear differentiation antigen (MNDA)] and the presence of cytogenetic abnormalities described previously in nodal follicular lymphoma [B cell lymphoma 2 (BCL2) and BCL6 breaks, 1p36 chromosomal region deletion (del 1p36)] in a series of 48 cutaneous follicular and marginal zone lymphomas [cutaneous follicular lymphoma (CFL) and cutaneous marginal zone lymphoma (CMZL)]...

It is unclear whether AL amyloidoma of the skin/subcutis represents a distinct entity, an indolent precursor of systemic amyloidosis, or a manifestation of cutaneous marginal zone lymphoma (cMZL). We collected 10 cases of cutaneous AL amyloidoma in order to better characterize the clinicopathologic features of this elusive entity (M:F=4:6; median age: 62.5 y, range: 31 to 82 y). Nine patients had a solitary nodule or plaque on the lower extremity (n=7), upper extremity (n=1), or chin (n=1). One patient had an AL amyloidoma on the right thigh and a second lesion on the right arm showing histopathologic features of cMZL without amyloid deposits...
