OBJECTIVE: To analyze the clinical features and prognosis of patients with Castleman's disease (CD) and improve the diagnosis and treatment of CD. METHODS: Clinical data of patients diagnosed with CD by pathological biopsy in Gansu Provincial Hospital from January 2009 to November 2020 were retrospectively analyzed. According to clinical classification, the patients were divided into two groups: UCD (unicentric CD) group (n=20) and MCD (multicentric CD) group (n=9). The clinical manifestations, laboratory examination, treatment regimens, pathological examination and follow-up data were statistically analyzed. RESULTS: There were no significant differences in average age and gender ratio between UCD group and MCD group. In UCD patients, 80.0% were hyaline vascular type, and 20.0% were plasma cell type. In MCD patients, 33.3% were hyaline vascular type, 55.6% were plasma cell type, and 11.1% were mixed type. There was significant difference in pathological classification between the two groups (P=0.039). The UCD patients usually presented asymptomatic single lymph node enlargement with mild clinical symptoms, while the MCD patients were characterized by multiple superficial and deep lymph node enlargement throughout the body. The incidences of asthenia, splenomegaly, serous effusion in MCD group were higher than those in UCD group (P<0.05). Meanwhile, the incidences of anemia, hypoproteinemia, increased ESR, elevated serum globulin and elevated β₂-microglobulin were significantly higher than those in UCD group too (P<0.05). There was no significant difference in the incidences of abnormal WBC, PLT and elevated LDH between the two groups (P>0.05). Among 20 patients with UCD, 13 cases reached complete remission (CR), 1 case achieved partial remission (PR). Among 9 patients with MCD, 3 cases received CR and 4 cases received PR. CONCLUSION Patients with CD requires pathological examination for diagnosis. Patients with UCD show mild clinical symptoms, good surgical treatment effect and good prognosis. Patients with MCD have diversified clinical manifestations and relatively poor prognosis, and these patients require comprehensive treatment.

Castleman's disease (CD) is a rare lymphoproliferative disorder. The etiology of CD may involve viral infection, abnormal modulation of cytokines, and angiogenesis. Human herpes virus (HHV) -8 infection and interleukin-6 (IL-6) overexpression may play key roles in the development of CD. Treatment options include surgical excision, radiation therapy, chemotherapy, antiviral therapy, and targeted therapy. No standardized treatment has been established for multicentric CD and the treatment efficacy usually is poor. Among newly available agents, the effectiveness of antiviral therapy against HHV-8 is unclear; anti-CD20 and anti-IL-6 receptor monoclonal antibodies have shown promising efficacy; thalidomide and bortezomib have shown their initial efficacy.

Objective: To investigate the clinical features, pathological phenotype, treatment and prognosis of Castleman's disease in children. Methods: Clinical data of 15 children diagnosed with Castleman's disease in Henan Provincial People's Hospital and the First Affiliated Hospital of Zhengzhou University from May 2010 to October 2019 were analyzed retrospectively. The clinical characteristics, laboratory examination and histopathological data were analyzed. Results: Among the 15 Castleman's disease patients, 12 were males and 3 females. The age of first visit was 12 (10, 15) years. The time from mass discovery to pathologic diagnosis was 9.0 (2.0, 13.0) months. The majority of patients were unicentric (13 cases), and the histopathological type was hyaline vascular (11 cases). Unicentric lesions were most common in the neck (11 cases), all 13 patients received complete surgical resection of the lesions, the follow-up time was 20.0 (13.5, 50.5) months, and the prognosis was good. Two cases were multicentric type, the pathological types were mixed variant, meeting the criteria of idiopathic Castleman's disease, the two children underwent partial surgical resection, one was treated with rituximab and prednisone and the other was treated with thalidomide and prednisone. The follow-up time was 32 months and 10 month, both of them had good prognosis. Conclusions: Most cases of Castleman's disease in children are diagnosed late, and the unicentric type is dominant. The most common pathological type is hyaline vascular, which is characterized by painless lymphadenopathy, while multicentric type has systemic symptoms and both of them have a good overall prognosis.

OBJECTIVETo discuss the clinical findings and treatment of paraneoplastic pemphigus (PNP) with Castleman's disease.

METHODSTo investigate the clinical, histopathologic and CT findings of 8 cases paraneoplastic pemphigus with Castleman's disease.

RESULTSAll of 8 patients were diagnosed PNP first and were found Castleman's tumor incidently during routine examination. All 8 cases showed severe erosion or ulcer of the oral mucosa with various skin lesions. Histopathologically, there were intraepidermal acantholytic vesicle, basal cell liquefaction, necrotic keratinocytes in the epidermis and lymphocyte infiltration in the upper dermis. CT scan appeared solitary mass in these patients. Some of them were attacked by bronchiolitis obliterans. All 8 patients were failed by use of predisone. Obvious relief of PNP and pulmonary lesion occurred after tumor was rescted.

CONCLUSIONSParaneoplastic pemphigus with Castleman's disease is a rare disease. The key step is to find and resect the tumor in abdomen. CT scan should be used to detect the tumor in patients with PNP, especially, when predisone was failed in treatment.

Paraneoplastic pemphigus is a rare autoimmune bullous dermatosis, which is caused by potential neoplasm, especially the Castleman's disease. Castleman's disease associated with paraneoplastic pemphigus is misdiagnosed frequently and easily in clinical practices. Furthermore, it is reported that the mortality rate for this disease is very high. Bronchiolitis obliterans is the most common complication and the most important cause of death. There was a female patient presenting recalcitrant mucocutaneous erosions, ulcers and scattered erythemas in the body. The patient was diagnosed and treated for pemphigus vulgaris with little success in Xiangya Hospital, Central South University in January 2015. Further investigations confirmed the diagnosis of paraneoplastic pemphigus with retroperitoneal tumor. Subsequently, the patient was treated with tumor resection in combination with intravenous immunoglobulin and corticosteroids. The pathology revealed that it was the Castleman's disease. Her mucocutaneous performance recovered obviously and the bronchiolitis obliteran did not appear in the follow-up. Castleman's disease associated with paraneoplastic pemphigus should be considered when mucosal and skin lesions showing no improvement under corticosteroids. Early and complete removal of the tumor together with immunotherapy could be beneficial to the patient's prognosis.
