Abstract:
A 46-year-old man was admitted in our hospital with hypoglycemia; his FPG was 43 mg/mL. Five years earlier, he underwent simultaneous surgeries for an adrenal adenoma, a benign Leydig cell tumor (LCT), and a malignant lymphoma. Based on the laboratory results, he was diagnosed as congenital adrenal hyperplasia (CAH) due to nonclassical 21-hydroxylase deficiency (21-OHD). On immunohistochemistry analysis using the antibody against adrenal-specific 11beta-hydroxylase antibody, the LCT showed both properties as a testicular cell and as an adrenal cell. The genetic background of 21-OHD might contribute to the development of malignant lymphoma. Such as a case of LCT and malignant lymphoma in a patient with 21-OHD seems to be rare.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
