The spectrum of intestinal mature T- and NK-cell neoplasms in a tertiary center in Taiwan with a high frequency of perforation. Pathol Res Pract 2022; 240:154184. [PMID: 36327820 DOI: 10.1016/j.prp.2022.154184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/30/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022]
Abstract
Primary intestinal T-cell lymphomas (PITLs) comprise enteropathy-associated T-cell lymphoma (EATL), monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), extranodal NK/T-cell lymphoma (ENKTL), anaplastic large cell lymphoma (ALCL), and intestinal T cell lymphoma, NOS (ITCL-NOS). MEITL is composed of monomorphic medium cells expressing CD8 and CD56, with a cytotoxic phenotype. We retrospectively analyzed 77 cases of intestinal T-cell lymphomas, 71 primary and six secondary, at a tertiary center in Taiwan from 2001 to 2021. Perforation occurred in 57 (74%) patients, including 56 (73%) at presentation and one after chemotherapy. The primary cases included MEITL (68%), ENKTL (14%), ITCL-NOS (13%), ALCL (4%), and EATL (1%). The perforation rate was 90%, 70%, and 22% in MEITL, ENKTL, and ITCL-NOS cases, respectively (p < 0.0001, Fisher's exact test). Most (75%; n = 36) MEITL cases were typical; while seven (15%) had atypical morphology and five (10%) exhibited atypical immunophenotype. The tumor cells of ITCL-NOS were pleomorphic, with various expression of CD8 or CD56. All METIL, ITCL-NOS and ALCL cases were negative for EBER; while all ENKTL cases, either primary or secondary, were positive for cytotoxic granules and EBER. The prognosis of PITL was poor, with a medium survival of 7.0, 3.3, and 3.7 months among patients with MEITL, ENKTL, and ITCL-NOS, respectively. Of the six secondary cases, the primary tumors orginated from nasal ENKTL (n = 5) and cutaneous PTCL-NOS (n = 1). We showed a wide spectrum of intestinal T-cell lymphomas in Taiwan, with MEITL as the most common PITL, a high rate of perforation, and a wider morphological and immunophenotypic spectrum.

Lai YL, Lin JK, Liang WY, Huang YC, Chang SC. Surgical resection combined with chemotherapy can help achieve better outcomes in patients with primary colonic lymphoma. J Surg Oncol 2011; 104:265-8. [PMID: 21472731 DOI: 10.1002/jso.21927] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2010] [Accepted: 03/14/2011] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND OBJECTIVES The colon is a rare location for gastrointestinal non-Hodgkin's lymphoma. We retrospectively analyzed the demographic data of patients with colonic lymphoma and the possible prognostic factors of the disease. METHODS We studied data obtained from 6,944 patients and performed a retrospective review of patients with primary colonic lymphoma (PCL) by using a pathology registry database. We employed well-established and accepted diagnostic criteria and clinical staging method. RESULTS Twenty-nine patients (19 men; 10 women) were diagnosed with PCL. The cecum was the most common tumor location (14/29 patients), and 17 cases (17/29) showed diffuse large-B-cell lymphomas. Four patients died of sepsis within 30 days of an emergency surgery for perforation of intestine. Two-thirds of the patients were in the early disease stages (stages I and II). The overall 5-year survival rate was 47.3%. Disease stage was not a prognostic factor for survival. The overall 5-year survival rate in patients treated with surgery followed by chemotherapy was statistically significant as compared to that in the patients treated with chemotherapy alone. CONCLUSION PCL is a rare malignancy of the gastrointestinal tract, and surgical resection should be considered a part of the standard treatment to achieve a better outcome.

Abstract
Perforation of the small intestine is the most lethal complication following induction chemotherapy for enteropathy-associated T-cell lymphoma (EATL). We report a case of EATL with a near perforated jejunal ulcer, and suggest a novel approach towards its management. Surgical resection followed by aggressive chemotherapy should limit chemotherapy-associated gastrointestinal toxicity, thus allowing patients to receive adequate dose and duration of chemotherapy. The presented case highlights potential benefits of surgical intervention prior to chemotherapy for EATL.

Abstract
GOALS Follicular lymphoma (FL) is a common nodal lymphoma. Primary gastrointestinal follicular lymphoma (GIFL) is rare and most commonly occurs in the elder women with indolent clinical course, mainly in the duodenum and terminal ileum. We conducted this study to characterize GIFL in Taiwan. STUDY A total of 13 cases were retrospectively collected in 4 hospitals in southern and eastern Taiwan up to 2006. Pathology review and immunohistochemistry were performed and the clinical data were obtained from chart review. RESULTS There were 5 men and 8 women with a median age of 58 years (range, 31 to 74; mean, 55). The most frequent site was ileum (7/13, 54%) with 4 tumors in the terminal ileum and the most common symptom was abdominal pain (8/13, 62%). Multiple lymphomatous polyposis was present in 6 patients (46%). Five (45%) of 11 tumors with surgical resection showed transmural involvement. Most of the cases revealed a predominantly follicular pattern (7/13, 54%) and low-grade disease (grades 1 and 2; 10/13, 77%). The tumors expressed CD10 (62%), Bcl-2 (77%), Bcl-6 (77%), and MUM1 (38%). Five patients (38%) were at stage IE and 8 (62%) at stage IIE. Treatment included surgery with or without chemotherapy. All patients achieved complete remission and relapse occurred in 3 patients. At a median follow-up time of 51 months (range, 3 to 180; mean, 63), 11 patients (85%) were disease free and no patient died of lymphoma. CONCLUSIONS We characterized the clinicopathologic features of the first series of GIFL in Taiwan. These tumors frequently involved ileum with a favorable prognosis.

Intestinal T-cell and natural killer-cell lymphomas in Taiwan with special emphasis on 2 distinct cellular types: natural killer-like cytotoxic T cell and true natural killer cell. Hum Pathol 2008; 39:1018-25. [PMID: 18482744 DOI: 10.1016/j.humpath.2007.11.003] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2007] [Revised: 09/01/2007] [Accepted: 11/07/2007] [Indexed: 10/22/2022]
Abstract
Primary intestinal lymphomas are rare, especially the T-cell and natural killer (NK)-cell types. Enteropathy-type T-cell lymphoma (ETL) is the most characteristic of the intestinal T-cell and NK-cell lymphomas (ITNKLs) defined in the World Health Organization classification. However, typical ETL is rare in nonendemic areas for celiac disease, which include Taiwan. With the exception of ETLs, ITNKLs comprise heterogeneous subtypes such as anaplastic large cell lymphoma, nasal-type NK/T-cell lymphoma and peripheral T-cell lymphoma, unspecified. Furthermore, the literature results with respect to the association between Epstein-Barr virus (EBV) and ITNKL are contradictory. To define the clinicopathological features of primary ITNKLs and develop a better understanding of their relationship with EBV in Taiwan, therefore, we investigated a sample of 11 patients based on the new World Health Organization classification using immunostaining, in situ hybridization for EBV detection, and polymerase chain reaction (PCR) for evaluation of T-cell receptor clonality. In conclusion, 2 distinct groups of primary ITNKLs were identified in our Taiwanese sample. The 6 group A cases were non-EBV-associated ETLs, prevalent in the jejunum and/or ileum. They were composed of monotonous round-ovoid medium-sized nuclei and had little pale cytoplasm. The immunophenotypes of these tumors were consistently CD3+, CD4-, CD8+, CD56+, T-cell intracellular antigen 1+, and Epstein-Barr early region- and monoclonal for T-cell receptor PCR, which indicated NK-like cytotoxic T-cell origin. The 5 group B cases were EBV-associated nasal-type NK/T-cell lymphomas prevalent in the ileum or cecum of younger patients. The neoplastic cells had polymorphous medium to large angulated nuclei and moderate cytoplasm, with immunologic phenotypes of CD4-, CD8-, variable cytoplasmic CD3varepsilon+, CD56+, T-cell intracellular antigen 1+, and Epstein-Barr early region 1+, and germ line PCR result for T-cell receptor, which indicated true NK-cell origin. The grave prognoses for the 2 groups did not differ significantly.

Abstract
A variety of miscellaneous conditions affect the appendix, both as incidental findings and as causes of clinical signs and symptoms that often mimic appendicitis. Congenital abnormalities of the appendix are rare; the two most commonly reported are congenital absence and appendiceal duplication. Diverticular disease may be an incidental finding, but when inflamed, can be clinically confused with appendicitis. Endometriosis of the appendix, which usually occurs in the setting of generalized gastrointestinal endometriosis, often presents as acute appendicitis, but may present as intussusception, lower intestinal bleeding, and, particularly during pregnancy, perforation. Peritoneal endosalpingiosis often involves the appendiceal serosa and occasionally the wall but has no clinical manifestations in contrast to endometriosis. Vasculitis may be either isolated to the appendix or part of a systemic vasculitis, most often polyarteritis nodosa. Neural proliferations of the appendix include lesions associated with von Recklinghausen's disease, as well as mucosal and axial neuromas that are theorized to progress to fibrous obliteration of the appendix. Mesenchymal tumors of the appendix are most often of smooth muscle type, usually leiomyoma but rarely leiomyosarcoma; nonmyogenic neoplasms such as gastrointestinal stromal tumor, granular cell tumor, Kaposi's sarcoma, and miscellaneous other curiosities occur rarely. Lymphoma affects the appendix exceptionally; in children, Burkitt lymphoma is most common whereas in adults, large cell lymphomas and low grade B-cell lymphomas predominate. Secondary involvement of the appendix by leukemia has been reported. Secondary involvement of the appendix by carcinomas of the female genital tract, particularly ovary, and diverse other sites are in aggregate common but only rarely a clinical or pathological difficulty. Occasionally, however, appendiceal neoplasia that is secondary from another site may dominate the clinical picture and lead to potential pathologic misdiagnosis as primary appendiceal disease.
