Breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare, breast implant–associated T-cell lymphoma in which CD30 is expressed and anaplastic lymphoma kinase (ALK) expression is absent.

Excerpt ALK-negative anaplastic large cell lymphoma (ALK (-) ALCL) is an uncommon CD30-positive T-cell lymphoma that presents a major diagnostic challenge. It affects individuals in a wide age range and a variety of nodal and extranodal sites. anaplastic lymphoma kinase (ALK) into ALK+ or ALK– disease.(1, 6, 7) Breast Implant-Associated ALCL (BIA-ALCL) is found in either the fibrous capsule or seroma fluid (effusion) surrounding the implant and is similar to cutaneous ALCL with respect to the presence of CD30+ and ALK- cells.(7,8) How common is BIA-ALCL? CD30 immune staining: A laboratory test is performed on the fluid that was obtained to detect the presence of CD30, a substance that occurs when T-cell lymphocytes are activated. If CD30 is present, it indicates that BIA-ALCL cannot be ruled out and further tests are required. The differential diagnosis for ALK‐negative ALCL in this patient included primary sa‐, pc‐, primary systemic, and secondary ALCL. 6, 11-13 The primary tumor specimen from the patient was most consistent with a diagnosis of sa‐ALCL by tissue histology and immunostaining, although pc‐ALCL is a closely related disease with many shared Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a very rare CD30-positive ALK-negative T-cell non-Hodgkin lymphoma included as a provisional entity in the 2017 WHO classification of lymphoid neoplasms.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a newly included provisional entity in the 2016 revision of the World Health Organization classification, is a distinct form of CD30-positive T-cell non-Hodgkin lymphoma that arises in association with a breast implant after reconstructive or cosmetic surgery. Histological analysis of seroma fluid or excised tissue is the mainstay of diagnosis, and CD30 and ALK status is key to the diagnosis of BIA-ALCL. For disease localised to the implant capsule, in the majority of cases, removing the implant and any capsular tissue surrounding it successfully treats the disease.

19 Jan 2021 BIA-ALCL is an uncommon T-cell non-Hodgkin lymphoma characterized as CD30 positive and anaplastic lymphoma kinase (ALK) negative.

The average onset of seroma presentation is 8 to 9 years after implantation. The World Health Organization recognized breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) as a unique form of ALCL that can develop following breast implant, implantation.

It accounts for about 1 — 2% of all cases of non-Hodgkin lymphoma (NHL) in adults. ALCL usually starts in T cells but, in some cases, it is hard to tell what type of cell the cancer started in. This is called null-cell t 2017-05-25 This sub-type is always both CD30 positive and ALK negative. In most cases, BIA-ALCL is found in the scar tissue and fluid near the implant, but in some cases, it can spread throughout the body.

BIA-ALCL resembles CD30+ cutaneous lymphoproliferative disorder: ALK-, CD30+ anaplastic cells with an aberrant T-cell phenotype; overexpression of oncogenes (JUNB, SATB1, pSTAT3, SOCS3) in lymphomatoid papulosis; frequent apoptosis; complete spontaneous regression in lymphomatoid papulosis; partial spontaneous regression in cutaneous ALCL.

For disease localised to the implant capsule, in the majority of cases, removing the implant and any capsular tissue surrounding it successfully treats the disease. Anaplastic large cell lymphomas (ALCLs) are an uncommon group of T-cell non-Hodgkin lymphomas that universally express CD30. Tumor cells are CD30 positive, lack expression of anaplastic lymphoma kinase (ALK) and lack gene rearrangements involving the ALK gene on chromosome 2p23.

Suggested theories of the cause of BIA-ALCL include textured implant particulate which are CD30 positive and anaplastic lymphoma kinase (ALK) negative by

The fluid should be tested for CD30, a protein that is found in higher than normal amounts on lymphoma cells, particularly in BIA-ALCL. If the fluid tests positive for CD30, the fluid should also be tested for anaplastic lymphoma kinase (ALK), a protein that helps control cell growth.
