Cutaneous Intravascular Natural Killer–Cell Lymphoma

Cutaneous intravascular natural killer-cell lymphoma: a rare case and review of the literature.

Intravascular large B-cell lymphoma with prominent cutaneous manifestation

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal diffuse large B-cell lymphoma (DLBCL) characterized by selective growth of neoplastic cells within the vascular lumen. IVLBCL involves all types of organs and mostly is associated with poor prognosis, but patients with cutaneous variant have significantly better survival. In this article we report a case of 80-year-old...

Primary cutaneous blastic natural killer cell lymphoma.

Sir, Blastic natural killer-cell lymphoma, also called “agranular CD4+ CD56+ haematodermic neoplasm” is an uncommon type of tumour, which is included in the new World Health Organization (WHO) classification as a malignancy derived from natural killer (NK) cells. It is very aggressive, affecting many organs, and skin involvement is highly characteristic. Several origins have been proposed, but ...

Intravascular Large B-cell Lymphoma: A Report of Two Cases

One of the rare variants of extranodal large B-cell lymphoma is intravascular large B-cell lymphoma (IVLBCL). Characteristics of IVLBCL include intraluminal selective proliferation of atypical lymphoid cells in small to medium-sized vessels. The etiologic of IVLBCL is unknown, but due to the growth pattern of this tumor, it is speculated that IVLBCL is caused by a defect in homing receptor of t...

Blastic CD56+ natural killer-cell lymphoma with primary cutaneous manifestation.

T/natural killer-cell lymphomas belong to a heterogeneous group of non-Hodgkin lymphomas with predominant extranodal, often cutaneous, manifestations. In contrast to B- and T-cell lymphomas, T/NK-cell lymphomas were only recently regarded as a distinct entity. These rather aggressive malignancies arise from cytotoxic T cells, NK-cells or NK-like T cells, which share several phenotypic and funct...
