Pitfalls in the Diagnosis of Anaplastic Large Cell Lymphoma with a Small Cell Pattern

CLINICAL FEATURES AND TREATMENT OUTCOME IN 26 CASES WITH Ki-l (CD30) POSITIVE ANAPLASTIC LARGE CELL LYMPHOMA

In order to present the clinical features and outcome of patients with Ki-l positive lymphoma and also the role of treatment modalities in this type of malignant disease, twenty-six patients with peripheral lymphadenopathy and a biopsyproven diagnosis ofKi-l positive lymphoma referring to the Radiation Oncology Department during a seven year period were treated with chemotherapy and radioth...

Anaplastic Large Cell Lymphoma Associated with Breast Implant: A Case Report

Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

Anaplastic Large Cell Lymphoma Associated With Breast Implants

A forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. Tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. Subsequently the patient developed axillary lymph adenopathy. Excisional biopsy was performed. Flow cytometry was non-diagnostic. She conti...

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...

ALK- negative Anaplastic Large Cell Lymphoma of Bone

Hodgkin Lymphoma and Anaplastic Variants of Non-Hodgkin Lymphoma

  Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods:...
