[Clinical Characteristic of Castleman Disease with Renal and Orbit Involvement].

OBJECTIVE

To explore the clinical characteristics, diagnosis, and treatment methods of one patient with idiopathic multicentric Castleman disease (iMCD), in order to strengthen the understanding of this rare disease.

METHODS

The clinical manifestations, diagnosis and treatment process, and prognosis of one patient with iMCD admitted to our hospital were retrospectively analyzed.

RESULTS

The patient was a 45-year-old female with swollen bilateral orbit, edema of lower limbs, multiple serosal cavity effusion, thrombocytopenia, renal insufficiency, and multiple lymph node enlargement. Lymph node biopsy suggested mixed type of Castleman disease. Combined with pathology, imaging and laboratory examination, the patient was finally diagnosed with mixed type of iMCD. After six cycles of R-COP regimen chemotherapy, the patient achieved complete remission.

CONCLUSIONS

Castleman disease with renal and orbit involvement is rare in clinic and easy to be misdiagnosed. It should be distinguished from lymphoma. The patient has been treated with R-COP regimen, and obtained good short-term efficacy.
