Castleman disease (CD) is a rare and highly heterogeneous lymphoproliferative disorder, with clinical and pathological features ranging from asymptomatic localized lesions to life-threatening systemic inflammatory responses. In recent years, the classification system of CD has been increasingly refined, with both unicentric CD (UCD) and multicentric CD (MCD) expanding into multiple subtypes with distinct clinical characteristics. Although the classification framework has become more sophisticated, some subtypes still lack specific biomarkers, and the categorization of certain entities remains controversial. This review summarizes advances in CD classification approaches over the past years, explores the clinical features and identification of newly proposed subtypes, and analyzes current challenges, aiming to provide a reference for optimizing diagnostic and therapeutic strategies.

Purpose: Corneal melanoma (CM) is a rare malignancy that develops from melanocytes within the cornea, constituting a minority of all ocular tumors. In this study, we sought to investigate the clinicopathological characteristics correlated with the prognosis of CM patients. Methods: We collected patients with CM between 1983 and 2018 from the Surveillance, Epidemiology, and End Results (SEER) database. Cox proportional hazards regression was used for univariate analysis to value hazard ratio of malignant CM versus spindle cell melanoma and nodular melanoma subgroups. Kaplan-Meier survival analysis and log-rank test were also performed to identify additional prognostic markers and confirm the findings of the Cox hazard ratio. Results: A total of 29 eligible patients were collected in our study. Age at diagnosis, laterality, primary site, tumor size, the extent of disease, marital status, income, residential area, and treatment showed no significant prognostic factors for CM patients (p > 0.05). However, when concerned with the primary site of malignant melanoma, spindle cell melanoma and nodular melanoma were found to show significantly poorer prognosis in CM patients (both p < 0.05). Conclusions Age at diagnosis, laterality, primary site, tumor size, the extent of disease, and treatment were not significant prognostic indicators for CM patients. Spindle cell melanoma and nodular melanoma were notable for showing worse survival outcomes than malignant melanoma. Although the sample size in the SEER database was limited, our findings may provide motivation for tailoring individualized treatments for patients with CM with different primary sites.

Objective To investigate the clinical characteristics,treatment responses,and prognosis of patients with idiopathic multicentric Castleman disease(iMCD)complicated by autoimmune hemolytic anemia(AIHA). Methods The patients diagnosed with iMCD in Peking Union Medical College Hospital from January 2010 to December 2023 and having complete baseline blood routine data were retrospectively enrolled in the study.The iMCD patients were further assigned into AIHA and non-AIHA groups based on baseline laboratory examinations,and the clinical characteristics and prognosis were compared between the two groups. Results A total of 341 patients with iMCD were enrolled in this study,including 277(81.2%)exhibiting anemia at baseline.Five(1.8%)patients were identified as having iMCD-AIHA,all of whom were iMCD-not otherwise specified type complicated by warm antibody-type AIHA,and two of them were simultaneously diagnosed with Evans syndrome.The timing relationship between the first onset of AIHA and iMCD diagnosis varied,with 2 patients experiencing their first hemolytic episode prior to the diagnosis of iMCD.In terms of treatment,the therapy targeting iMCD was effective in alleviating AIHA.The AIHA group had a poorer prognosis(HR=4.61,95% CI=1.08-19.80,P=0.040)and a lower 5-year survival rate(90% vs.60%,P=0.024)than the non-AIHA group.Conclusions iMCD-AIHA is clinically rare,and AIHA can occur at different stages of iMCD.Although the primary treatment principle remains targeting iMCD,great attention should be paid to the exacerbation of immune dysfunction caused by AIHA and the possible adverse prognosis it may bring.

Castleman's disease is a rare polyclonal lymphoproliferative disorder.This article reports the diagnosis and treatment of a 45-year-old female patient with idiopathic multicentric Castleman's disease.The patient presented recurrent fever,enlarged lymph nodes,and elevated levels of inflammation markers.After multiple serological examinations and tissue biopsies,she was diagnosed with hyaline vascular-type Castleman's disease.Initially,the patient received siltuximab targeting interleukin-6,which significantly improved her condition.Considering the cost and convenience of long-term treatment,she subsequently switched the therapy to an oral treatment regimen of thalidomide,cyclophosphamide,and prednisone (TCP),which maintained disease control.This report aims to highlight the diagnostic complexity and diversity of treatment options for idiopathic multicentric Castleman's disease,demonstrating the potential of the TCP regimen as a cost-effective treatment choice.

Objective:To investigate whether cavitation induced by ultrasound stimulated perfluorobutane microbubbles can enhance the therapeutic effect of colchicine and reduce its side effects on acute gouty arthritis (AGA) in rats.Methods:The AGA rat model was established by injection of monosodium urate (MSU) crystals. The rats were randomly divided into 6 groups (A: blank control group, B: model control group, C: cavitation group, D: standard concentration drug group, E: low concentration drug cavitation group, F: standard concentration drug cavitation group) according to whether they were given different doses of colchicine. The area under the curve (AUC) of contrast-enhanced ultrasound (CEUS) was calculated at 7 h and 8 h after MSU injection to compare the effect of cavitation on ankle blood perfusion. The symptoms of AGA were evaluated according to the degree of ankle swelling and gait score at 24 h. The infiltration of neutrophils was detected by HE staining, and the inflammatory response was analyzed by detecting the level of interleukin-1β (IL-1β) in plasma. Vascular dilatation was analyzed by detecting the concentration of endothelial nitric oxide synthase (eNOS). The degree of adverse reactions in each group was analyzed by gastrointestinal reaction score.Results:The CEUS blood perfusion and AUC values of the three groups with cavitation (groups C, E and F) were significantly higher than those of the non-cavitation groups (groups A, B and D) (all P<0.05). Compared with group D, there were no significant differences in the degree of ankle swelling, gait score, and plasma IL-1β level in group E (all P>0.05), but the plasma eNOS concentration was higher and the incidence of gastrointestinal reactions was significantly lower in group E (all P<0.05). Compared with group D, the degree of ankle swelling and gait score in group F were decreased, and HE staining showed that the degree of synovial infiltration of neutrophils in the ankle joints of AGA rats in group F was lighter (all P<0.05), but there was no significant difference in plasma IL-1β level and the incidence of gastrointestinal reactions between group D and group F (all P>0.05). Conclusions:The cavitation of perfluorobutane microspheres stimulated by ultrasound can enhance the blood perfusion of the ankle joint of AGA rats, enhance the therapeutic effect of local colchicine, and help to reduce the dosage of colchicine and its side effects.
