Humoral immunity against hepatitis B, tetanus, and diphtheria following chemotherapy for hematologic malignancies: a report and review of literature.

Malignancy and its treatment are major causes of secondary immunodeficiency in childhood. The authors investigated the effects of chemotherapy on humoral immunity against hepatitis B, tetanus, and diphtheria in children with hematologic malignancies. The authors recruited 54 patients with hematologic malignancies after the completion of chemotherapy (group A), 25 patients with newly diagnosed hematologic malignancies before initiation of chemotherapy (group B), and 74 healthy controls (group C).

Generalized myelolipoma.

Myelolipoma is a benign tumor originating from hematopoietic and adipose tissue. This tumor usually develops in the adrenal gland, but rare presentations of extraadrenal myelolipoma are also reported, which usually arise from the presacral region. Herein, we present a 6-year-old girl with myelolipoma with generalized involvement of her abdomen, pelvis, chest, and retroorbital region.
