BACKGROUND Extranodal nasal-type natural killer (NK)/T-cell lymphoma represents a rare entity, typically originating in the nasal cavity, palate or midfacial region. Signs and symptoms include non-specific rhinitis and/or sinusitis, nasal obstruction, epistaxis, facial swelling and development of deep necrotic ulceration in the midline of the palate, causing an oronasal defect. Differential dia...

UNLABELLED Extranodal natural killer (NK)/T-cell lymphoma, nasal type, is an uncommon lymphoma associated with the Epstein-Barr virus (EBV). It most commonly involves the nasal cavity and upper respiratory tract. Primary pulmonary NK/T cell lymphoma is extremely rare. If a patient with a NK or T-cell tumor has an unusual reaction to treatment or an unusual prognosis, it is wise to differentiate...

Intravascular large cell lymphoma is a rare subtype of extranodal large cell lymphoma characterized by the presence of neoplastic cells within the lumina of small vessels. Most cases of intravascular large cell lymphoma have a B-cell phenotype. To date, 12 cases of intravascular natural killer (NK/)/T-cell lymphoma (IVNKL) have been reported. Our case is A 47-year-old female presented with eryt...

Cutaneous T-cell lymphoma (CTCL), a heterogeneous group of extranodal non-Hodgkin’s lymphoma. In this study, we sequenced skin T cells on single cell level from patients with mycosis fungoides (MF), the most common type CTCL, and segregated clonal malignant non-clonal bystander by natural clonality identifier – receptor (TCR). Based our attention-ANN, an artificial intelligent method, identifie...

BACKGROUND The prognosis for patients with most forms of T-cell lymphoma is poor. Allogeneic hematopoietic stem-cell transplantation (HSCT) may improve the outcome. PATIENTS AND METHODS This study examines the outcome of 52 patients who underwent ablative or nonablative allogeneic HSCT for peripheral T-cell lymphoma (PTCL) or advanced mycosis fungoides/Sezary syndrome over a 12-year period at...

non-hodgkin lymphoma usually presents with generalized lymphadenopathy, but it can also involve any part of the human body. lymphomatous involvement of muscles is a rare presentation and has been reported to occur in only 1.1% in non-hodgkin lymphoma. here we, present a 32 year-old iranian man with primary involvement of spleen, bone, bone marrow and muscle, mimicking soft tissue sarcoma; core ...

The relative frequency of lymphoma types varies in different geographic region. Human Tcell lymphotropic virus type I (HTLV-I) infection is endemic in south-western Japan which leads to a high frequency of adult T-cell leukemia/lymphoma (ATLL). As compared to the West, East Asian countries have higher relative frequencies of Tand natural killer (NK)-cell lymphomas, which account for about 15-20...
