Secondary malignant neoplasm of left adrenal gland

Clinical Classification Guidelines

Medical Intelligence & Overview

Secondary malignant neoplasm of the left adrenal gland, classified under ICD-10 code C79.72, refers to a cancerous growth in the adrenal gland that has spread from another part of the body. Unlike primary adrenal cancers, which originate in the adrenal gland itself, secondary cancers are metastases, meaning they have traveled from a different primary tumor site and established in the adrenal glands. The adrenal glands are small, triangular-shaped organs located atop each kidney, responsible for hormone production and regulation of various bodily functions. When a secondary cancer involves the adrenal gland, it indicates the spread of malignancy, often signifying an advanced stage of cancer.
