[PMID: 38322452 PMCID: PMC10841960 DOI: 10.12998/wjcc.v12.i3.657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 12/17/2023] [Accepted: 01/02/2024] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND Anaplastic lymphoma kinase (ALK)-positive large B-cell lymphoma (LBCL) is an aggressive and rare variant of diffuse LBCL. Herein, we report an uncommon case of stage IE extranodal ALK-positive LBCL initially originating in the bulbar conjunctiva. CASE SUMMARY A 63-year-old woman presented with a mass in the left bulbar conjunctiva that had persisted for six months, accompanied by swelling and pain that had persisted for 3 d. Eye examination revealed an 8 mm slightly elevated pink mass in the lower conjunctival sac of the left eye. Microscopically, the tumor was composed of large immunoblastic and plasmablastic large lymphoid cells with scattered anaplastic or multinucleated large cells. Immunophenotypically, the neoplastic cells were positive for ALK, CD10, CD138, Kappa, MUM1, BOB.1, OCT-2, CD4, CD45, EMA, CD79a, CD38, and AE1/AE3, and negative for CD20, PAX5, Lambda, BCL6, CD30 and all other T-cell antigens. The results of gene rearrangement tests showed monoclonal IGH/IGK/IGL and TCRD rearrangements. Fluorescence in situ hybridization studies did not reveal any BCL2, BCL6 or MYC rearrangements. Furthermore, Epstein-Barr virus was not detected by in situ hybridization in the lesions. Based on the histopathological and imaging examinations, the neoplasm was classified as stage IE ALK-positive LBCL. No further treatments were administered. At the 6, 15, and 21 mo postoperative follow-up visits, the patient was in good condition, without obvious discomfort. This case represents the first example of primary extranodal ALK-positive LBCL presenting as a bulbar conjunctival mass, which is extremely rare and shares morphological and immunohistochemical features with a variety of other neoplasms that can result in misdiagnosis. CONCLUSION Awareness of the condition presented in this case report is necessary for early and accurate diagnosis and appropriate treatment.

Abstract
Anaplastic lymphoma kinase-positive (ALK+) large B-cell lymphoma (LBCL) is a rare CD20-negative aggressive lymphoma. Given its rarity, data on ALK + LBCL are scarce and limited to case reports and small case series. Our systematic review included 184 unique cases published in the literature and shows that ALK + LBCL can affect individuals at any age, has a male predominance and is not associated with chronic viral infections. The malignant cells express ALK, VS38c, BLIMP-1, EMA, c-MYC, and BOB-1. The STAT3/STAT5, PI3K/AKT, PLCG2, and ERK pathways are important in the pathophysiology of ALK + LBCL. The prognosis of ALK + LBCL is poor with a 5-year survival rate of 28%. Early disease stage is associated with better outcomes. ALK inhibitors and other targeted agents could be of value in the treatment of ALK + LBCL. Additional research is needed to better understand, diagnose and treat ALK + LBCL.

Diagnosis and treatment of pediatric anaplastic lymphoma kinase-positive large B-cell lymphoma: A case report. World J Clin Cases 2021; 9:4268-4278. [PMID: 34141790 PMCID: PMC8173411 DOI: 10.12998/wjcc.v9.i17.4268] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 03/15/2021] [Accepted: 03/29/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Anaplastic lymphoma kinase-positive (ALK+) large B-cell lymphoma (LBCL) is a rare type of lymphoma with high invasiveness and rapid progression. It occurs in all age groups, but is extremely rare in children. The lesions mainly involve the lymph nodes and may present with extra-nodal involvement. Response to conventional chemotherapies and local radiotherapy is poor, with a 5-year overall survival of less than 40%. Recently, the use of ALK inhibitors for the treatment of this disease has been reported.
CASE SUMMARY We present a case of a 12-year-old boy diagnosed with ALK+LBCL. The patient had a 2-mo medical history of a calvarial mass, extensive systemic involvement, and positive bone marrow clathrin heavy chain (CLTC)-ALK fusion gene. Complete remission 1 (CR1) was achieved using the modified LMB89 Group C regimen followed by autologous stem cell transplantation. The patient relapsed 3 mo later. He then achieved CR2 with three short courses of chemotherapy (COP, reduced-dose ICE, low-dose Ara-c+VP16) and continuous alectinib targeted therapy. Afterward, allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed. At 16 mo after the allo-HSCT, the patient was still in CR2.
CONCLUSION The modified LMB89 Group C regimen and ALK inhibitors are effective. Allo-HSCT should be performed after remission.
