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 superior vena cava lymphoma originating from the endothelium of a large vein is very rare. A 70-year-old man was admitted to the hospital; computed tomography showed a tumor limited to the inside of the superior vena cava, completely occluding the vessel. A transjugular biopsy confirmed the diagnosis of diffuse large B-cell lymphoma, which was diffusely positive for CD30. Rituximab monotherapy followed by five courses of R-CHOP chemotherapy induced a complete remission. There was no recurrence after two years...

Intravascular lymphoma (IVL) is a rare entity. Most cases are a variant of extranodal diffuse large B-cell lymphoma, and fewer than 10% of the published cases are of T-cell origin. Only intravascular B-cell lymphoma is recognized as a distinct entity in the most recent WHO classification of lymphoproliferative disorders. We describe a case of cutaneous NK/T IVL, with a cytotoxic immunophenotype and EBV positivity. However, our case was immunohistochemically negative not only for TCR-βF1 and TCR-γ (TCR-silent), but also for CD56, making it the first triple-negative NK/T IVL case to be described...

BACKGROUND: Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal large B-cell lymphoma. It is characterized by the proliferation of tumour cells exclusively intraluminally in small blood vessels of different organs. The clinical manifestation depends on the type of organ affected, additionally, a haemophagocytic syndrome can be observed in some patients. OBJECTIVE: Due to the rarity of this lymphoma and in spite of detailed immunohistochemical investigations the exact nosology of this cancer is only incompletely understood...

BACKGROUND: In patients presenting with rapidly progressive dementia, prion disease may enter the differential diagnosis. The commonest malignancies masquerading as prion disease are primary CNS lymphoma and intravascular large B-cell lymphoma, both rare and difficult to diagnose without brain biopsy. CASE PRESENTATION: This 82-year-old lady with a past history of hypertension, presented with rapidly progressive cognitive impairment and ataxia. The possibility of sCJD was raised...

A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings...

Intravascular selective growth of neoplastic B lymphocytes is a characteristic finding of intravascular large B-cell lymphoma (IVLBCL). However, because neoplastic B cells of IVLBCL grow merely in the lumina of capillaries or small vessels, primary IVLBCL of the great vessels is considered exceptional. To our knowledge, only 2 primary B-cell lymphomas in the lumina of the vena cava have been reported. However, there has been no report of primary B-cell lymphoma with intra-aortic growth. We describe a novel manifestation of primary Epstein-Barr virus-positive large B-cell lymphoma mainly affecting the lumina of the aorta and its major branches in a 76-year-old man...

An 87-year-old woman presented with a 3-month history of fever, edema of the lower legs, and gait disturbance. A laboratory examination revealed high serum levels of myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA). Although microscopic polyangiitis was initially suspected and treated, the patient subsequently developed transient hemiparesis and disturbed consciousness. Brain magnetic resonance imaging/angiography revealed infarct-like lesions, pachymeningeal involvement, and diffuse cerebral vasoconstriction...

BACKGROUND/AIMS: This study examined the role of random normal skin biopsy in the diagnosis of intravascular lymphoma (IVL) in adult Western patients with clinically diagnosed hemophagocytic lymphohistiocytosis (HLH). METHODS: In a retrospective chart review study, we analyzed a total of 59 skin biopsies that were performed to diagnose IVL in 21 adult patients with HLH seen at Stanford Hospital between 2004 and 2016. RESULTS: Out of the 59 skin biopsies, 42 were taken from clinically normal-appearing skin and 17 from clinically abnormal-appearing skin...

BACKGROUND: Random skin biopsy (RSB) is a method for diagnosis of intravascular lymphoma (IVL). However, the indications for RSB to diagnose IVL have not yet been established. The aim of this study was to determine the appropriate indications for RSB to diagnose IVL. METHODS: Thirty-two patients with fever of unknown origin (FUO) and without skin lesion underwent RSB for diagnosis of IVL. Clinical data, including fever, neurological symptoms, hematologic disorders, organomegaly, bone marrow (BM) study, hypoxemia and serum level of lactate dehydrogenase (LDH), were evaluated...

A 63-year-old man presented with right-sided hemianopia and unsteady gait. Brain MRI revealed multiple hyperintense infarct-like lesions on diffusion-weighted images (DWI). Hyperintensity persisted in some of these lesions even after 6 weeks, although his symptoms were ameliorated then. The patient developed episodic dizziness and a transient event of apraxia at 18 weeks after the first episode. Brain MRI revealed additional hyperintense lesions on DWI, which persisted even after 7 weeks. Eventually, the patient manifested cauda equina syndrome 39 weeks after the first episode...

Intravascular accumulation of lymphocytes in any body site can raise concerns for a lymphoproliferative disorder, mainly intravascular lymphoma, leukemia, or a form of angiocentric lymphoma. We recently found an intravascular lymphocytic accumulation of non-neoplastic nature in a uterine cervix. The aim of the study was to define the frequency and the nature of this observation in the uterine cervix. Thirty cervical excision specimens including 23 cone biopsies and 7 hysterectomies were examined for the presence of intravascular accumulation of lymphocytes...

First described in 1959, intravascular lymphoma (IVL) remains one of the most clinically challenging diagnoses due to its diverse and non-specific clinical manifestations and evasiveness in detection by standard investigations. Indeed, IVL deserves the title of 'medicine's greatest imitator'. We highlight a case of IVL where the diagnosis came too late in the clinical course, detected by random skin biopsy. Clinicians should strongly consider this diagnosis in presentations with persistent symptomatology despite appropriate interventions...

RATIONALE: Intravascular large B-cell lymphoma (IVLBCL) is an extremely rare subtype of large B-cell lymphoma characterized by the presence of lymphoma cells within the lumen of small blood vessels. IVLBCL presents with nonspecific symptoms such as fever, weight loss, and bleeding. Because of its rarity and unremarkable clinical presentation, a timely diagnosis is very challenging. PATIENT CONCERNS: A 71-year-old Korean man complained of fever, but apart from pretibial pitting edema and mild thrombocytopenia, the physical examination and laboratory test findings were unremarkable...

BACKGROUND Intravascular lymphoma (IVL) is a rare lymphoproliferative disorder characterized by the proliferation of large B lymphoma cells within the lumen of small-caliber blood vessels. Clinical features are nonspecific, presenting as a systemic disease with fever and may be life-threatening. Antemortem diagnosis is difficult but may be made with biopsies of affected tissues or with random skin biopsies. CASE REPORT We report the case of a 66-year-old white woman presenting with fever of unknown origin (FUO) who developed neurologic, pulmonary, and hematologic manifestations...
