C74.90

Clinical Causes: Genetic mutations or inherited genetic syndromes Environmental factors such as exposure to radiation and certain chemicals Previous history of cancers that might spread to the adrenal glands Hormonal imbalances that may stimulate tumor growth Unknown factors in many cases, as research is ongoing

Key Symptoms: Unexplained weight loss Abdominal or back pain Detected as a lump in the abdomen Symptoms related to hormone excess, such as high blood pressure, muscle weakness, or rapid heartbeat Fatigue and general feelings of malaise Feeling of fullness or early satiety

Diagnosis Path: Diagnosing malignant tumors of the adrenal gland typically involves a combination of imaging and laboratory procedures. These may include: - **Imaging Tests:** Computed tomography (CT) scans, magnetic resonance imaging (MRI), and ultrasound to visualize the adrenal glands and assess the tumor's size and spread. - **Blood and Urine Tests:** To evaluate hormone levels and identify hormonal imbalances caused by the tumor. - **Biopsy:** Needle or surgical biopsy to obtain tissue samples for histopathological examination, confirming malignancy and ruling out other conditions. - **Additional Tests:** PET scans and adrenal vein sampling may be used to gather more detailed information about tumor activity and location. Early and precise diagnosis is essential for planning effective treatment strategies.

Treatment Protocols: The management of malignant adrenal tumors depends on the tumor's size, location, extent, and whether it has spread. Common treatment options include: - **Surgical Removal:** Often the primary treatment, especially if the tumor is localized. Complete adrenalectomy, the surgical removal of the affected adrenal gland, is generally performed. - **Radiation Therapy:** May be used to target residual cancer cells after surgery or to palliate symptoms. - **Chemotherapy:** Utilized in cases where the tumor has spread or cannot be entirely removed; specific agents depend on tumor type. - **Targeted Therapy:** Emerging treatments that focus on specific genetic or molecular characteristics of the tumor. - **Hormone Therapy:** To manage symptoms related to hormone production caused by the tumor. Treatment plans are usually tailored to each individual, often involving a multidisciplinary team of specialists.
