Lymphomatoid Papulosis (LyP) is a rare skin disorder characterized by chronic, recurrent papules and nodules that heal spontaneously. This report discusses an 8-year-old Filipino female with a three-month history of erythematous pruritic papules evolving into plaques. A skin biopsy confirmed CD30-negative LyP, and treatment with Methotrexate resulted in significant improvement of the lesions. This case illustrates the complex diagnostic and therapeutic journey of LyP in children, emphasizing the importance of careful clinicopathologic correlation and the challenges of management due to the lack of curative therapy and the risk of malignant transformation.

18F-Fluorodeoxyglucose (18F-FDG) PET/CT scan is a vital imaging modality in the majority of oncologic situations. It is proven useful in staging, management and monitoring of lymphomas. Numerous subtypes of lymphomas exist; however, we present the first documented case of a 56-year-old, Filipino, male patient who is diagnosed with mantle cell lymphoma of the conjunctiva (MCL). MCL is an extremely rare type of extranodal non-Hodgkin lymphoma and has an aggressive nature with an estimated incidence of 2-4/1,000,000. This case highlights the critical role that PET/CT scans play in directing treatment decisions and monitoring the response of conjunctival MCL to therapy.

Duodenal-type follicular lymphoma (DFL) is a unique subtype of follicular lymphoma (FL), which often involves the second portion of duodenum (descending part of duodenum). Due to its specific pathological features, such as lack of follicular dendritic cells meshwork and disappearance of activation-induced cytidine deaminase expression, DFL presents an inert clinical course and is often confined to the intestinal tract. Inflammation-related biomarkers suggest that the microenvironment may play a likely role in the pathogenesis and favorable prognosis of DFL. Since patients generally have no obvious clinical symptoms and low progression rate, the treatment regimen for DFL is mainly observation and waiting (W&W) strategy. This study will review the latest research progress of epidemiology, diagnosis, treatment and prognosis of DFL in recent years.

OBJECTIVE: To analyze the clinical characteristics of the patients with B-cell chronic lymphoproliferative disease（B-CLPD） in the new drug era and the effect of new drug treatment on efficacy and survival. METHODS: The clinical and laboratory data of 200 cases B-CLPD patients diagnosed between April 2015 and August 2021 were analyzed retrospectively. The clinical efficacy and survival of the patients under different treatments including Bruton tyrosine kinase（BTK） inhibitors， rituximab， and chemotherapy alone were analyzed. The prognostic factors affecting the survival of patients were analyzed by univarite analysis and multivariate analysis. RESULTS: There were 119 male（59.5％） and 81 female（40.5%） in 200 cases B-CLPD patients， the sex ratio(male/female) was 1.5∶1 with median age of 61（30- 91） years old. The distribution of subtypes were as fallows: 51 cases (25.5%) of chronic lymphocytic leukemia/small lymphocytic lymphoma（CLL/SLL）， 64（32.0%） cases of follicular lymphoma（FL）， 40（20.0%） cases mantle cell lymphoma（MCL）， 30（15.0%） cases of marginal zone lymphoma（MZL）， 10（5%） cases of lymphoplasmacytic lymphoma/waldenstrom macroglobulinemia（LPL/WM）， 5（2.5%） cases of B cell chronic lymphoproliferative disorders unclassified（B-CLPD-U） . The main clinical manifestation of 102 patients was lymph node enlargement, 32 cases were complicated with B symptoms. Among CLL/SLL patients， there were 12（23.5%） cases in Binet A and 39（76.5%） cases in Binet B/C. There were 29 patients（20.9%） in Ann Arbor or Lugano stage I-II and 110 cases（79.1%） in stage III-IV of other subtypes. The complete remission（CR） rate was 43.1%（25/58）， 40.2%（39/97）， 7.1%（1/14）， and overaIl response rate（ORR） was 87.9%（51/58）， 62.9%（61/97）， 28.6%（4/14） in the groups of BTK inhibitors， rituximab-based therapy， and chemotherapy alone. The 3-year OS rate and PFS rate in all patients was 79.2% and 72.4% respectively. The 3-year OS rate of patient with MZL, CLL/SLL, FL,WM was 94.7%, 87.7%, 86.8% and 83.3% respectively, while the 3-year OS rate of MCL was only 40.6%, which was significantly lower than other subtypes. The median OS of patients treated with BTK inhibitors and rituximab-based therapy was 20.5 and 18.5 months respectively， and the 3-year OS rate was 97.4% and 90.7%. However， the median PFS of patients receiving chemotherapy alone was 4 months， and the 1-year OS rate was 52.7%， which was statistically significant compared with the other two groups（P<0.05）. Univarite analysis showed that anemia， elevated lactate dehydrogenase， elevated β2-microglobulin， and splenomegaly were the poor prognostic factors for OS（P<0.05）， elevated lactate dehydrogenase was also poor prognostic factors for PFS（P<0.05）. Multifactor analysis showed that anemia and elevated lactate dehydrogenase were the independent poor prognostic factors for survival（P<0.05）. CONCLUSION The clinical features of B-CLPD was various， anemia and elevated lactate dehydrogenase are the prognostic factors for poor survival. BTK inhibitors and new immunotherapy can improve the survival and prognosis of patients in the new drug era.

Objective: To examine the clinical characteristics and prognostic factors of elderly patients with mantle cell lymphoma (MCL) and the impact of nutrition and underlying diseases on the prognosis of elderly patients with MCL. Methods: retrospectively analyzed 255 elderly patients with MCL from 11 medical centers, including Peking University Third Hospital between January 2000 and February 2021. We analyzed clinical data, such as age, gender, Mantle Cell Lymphoma International Prognostic Index score, and treatment options, and performed univariate and multivariate prognostic analysis. We performed a comprehensive geriatric assessment on elderly MCL patients with medical records that included retraceable underlying disease and albumin levels, and we investigated the impact of basic nutrition and underlying disorders on MCL prognosis in the elderly. Results: There were 255 senior individuals among the 795 MCL patients. Elderly MCL was more common in males (78.4%), with a median age of 69 yr (ages 65-88), and the majority (88.6%) were identified at a late stage. The 3-yr overall survival (OS) rate was 42.0%, with a 21.2% progression-free survival (PFS) rate. The overall response rate (ORR) was 77.3%, with a 33.3% total remission rate. Elderly patients were more likely than younger patients to have persistent underlying illnesses, such as hypertension. Multivariate analysis revealed that variables related with poor PFS included age of ≥80 (P=0.021), Ann Arbor stage Ⅲ-Ⅳ (P=0.003), high LDH level (P=0.003), involvement of bone marrow (P=0.014). Age of ≥80 (P=0.001) and a high LDH level (P=0.003) were risk factors for OS. The complete geriatric assessment revealed that renal deficiency was associated with poorer OS (P=0.047) . Conclusions: Elderly MCL patients had greater comorbidities. Age, LDH, renal function, bone marrow involvement, and Ann Arbor stage are all independent risk factors for MCL in the elderly.

Non-Hodgkin lymphoma (NHL) is a common lymphoid hematological malignancy, the treatment and prognosis of NHL have always been the focus of clinical attention. Chemotherapy is the main first-line treatment, but there is still no effective treatment for patients with poor response to chemotherapy, recurrence or progression within a short period of time after treatment, and new and effective drugs need to be developed clinically. As the only clinically validated oral selective inhibitor of nuclear export (SINE), Selinexor has been approved for the treatment of relapsed/refractory diffuse large B-cell lymphoma and multiple myeloma, clinical attempts are being made to apply it to the treatment of other hematological malignancies.This article reviews the anti-tumor mechanism of Selinexor and the latest research progress in its application in NHL, and provides ideas for a more diverse, standardized and effective applications of Selinexor in NHL.
