ABSTRACT
Objective:
To investigate clinicopathological features of 4 cases of intravascular large B-cell lymphoma (IVLBCL) .Methods:
Clinical and pathological data were collected from 4 patients with histopathologically confirmed IVLBCL in Department of Dermatology, Peking Union Medical College Hospital from January 2020 to November 2020, and retrospectively analyzed.Results:
The 4 patients were aged 57 - 76 years, including 2 males and 2 females. Of the 4 patients, all had neurological symptoms, 3 had fever, 3 exhibited impaired exercise tolerance and suffocation, and 3 exhibited pitting edema of the body. Case 1 presented with a cherry hemangioma-like papule measuring 0.2 cm in diameter on the back, and case 2 with telangiectasia on the left breast and upper abdomen. Six skin samples were taken from the 4 patients for histopathological and immunohistochemical studies, and tumor cells were found in 1 cherry hemangioma-like lesion and 1 lesion of telangiectasia, as well as in 2 of 4 normal skin samples. Histopathological findings mainly were dilated dermal blood vessels filled with large atypical mononuclear cells, and the atypical mononuclear cells were positive for CD20 immunohistochemically.Conclusion:
For those patients with suspected IVLBCL, hemangioma-like and telangiectasia lesions tend to show characteristic histopathological and immunohistochemical findings, and a biopsy of normal skin can facilitate early diagnosis of IVLBCL.
