A malignant adrenal medulla tumor is a cancer that starts in the inner part of the adrenal gland (the medulla), which is made of “chromaffin” cells. These cells normally make stress hormones (adrenaline, noradrenaline, and sometimes dopamine). When a tumor grows from these cells, it can release too much of these hormones and cause high blood pressure, fast heart rate, sweating, headache, and anxiety. Doctors call this tumor a pheochromocytoma when it is in the adrenal gland. It is called malignant only when it spreads (metastasizes) to places that do not normally have chromaffin cells—for example bone, liver, lung, or lymph nodes. That spread is the accepted way to define cancer in this tumor. Oxford AcademicWJGNet
A malignant adrenal medulla tumor is a cancer that starts in the inner part of the adrenal gland (the medulla). This part makes stress hormones called catecholamines (adrenaline/epinephrine, noradrenaline/norepinephrine, and sometimes dopamine). When the tumor spreads to places like bone, liver, lungs, or lymph nodes, doctors call it metastatic pheochromocytoma (or metastatic paraganglioma if the original tumor is outside the adrenal). These tumors can release too much hormone and cause dangerous spikes in blood pressure, headaches, sweating, palpitations, and anxiety. Care needs a team: endocrinology, oncology, nuclear medicine, surgery, cardiology, genetics, and anesthesia. Today, all pheochromocytoma/paraganglioma (PPGL) are considered to have some metastatic potential, so life-long follow-up is important. Oxford Academic+1PubMed
Other names
Pheochromocytoma (PCC) — the standard medical name for adrenal medulla tumors.
Metastatic pheochromocytoma — when it has spread to bone, liver, lung, or lymph nodes.
Pheochromocytoma–paraganglioma (PPGL) spectrum — the family of related tumors; paraganglioma is the similar tumor outside the adrenal glands.
Adrenal chromaffin cell tumor or adrenal medullary tumor — descriptive names used in reports.
Cancerous pheochromocytoma — a plain-language term patients may hear.
These terms all point to the same problem: an adrenal medulla tumor, and it is called malignant when there are metastases. Oxford Academic
Types
By location:
Adrenal (pheochromocytoma) — inside the adrenal gland.
Extra-adrenal (paraganglioma) — outside the adrenal; not the focus here, but part of the same PPGL family. nanets.net
By behavior:
Non-metastatic (often called “benign”) — has not spread.
Malignant (metastatic) — has spread to non-chromaffin sites; this is the accepted definition of malignant disease. Oxford Academic
By hormones released (“biochemical phenotype”):
Adrenergic (mostly adrenaline/epinephrine → spells, palpitations).
Noradrenergic (mostly noradrenaline/norepinephrine → sustained hypertension).
Dopaminergic (dopamine excess → may be “silent,” needs 3-methoxytyramine measurement). NCBI
By genetics (germline or somatic drivers):
Syndromic or mutation-defined subtypes (e.g., RET/MEN2, VHL, NF1, SDHx cluster, TMEM127, MAX, EPAS1/HIF2A, FH, EGLN1/PHD2, and others). These subtypes often predict where tumors arise, what hormones they make, how they image, and their metastatic risk (for example, SDHB is linked to higher risk of metastasis). PMCMedscapeBy age group:
Pediatric vs adult presentations (pediatric disease is rare but recognized). Nature
Causes
(Most “causes” are inherited gene changes that raise risk. Many patients have no family history.)
RET mutation (MEN2A/2B): raises risk of adrenal pheochromocytoma, often adrenergic. PMC
VHL mutation (Von Hippel–Lindau): drives noradrenergic tumors; may be bilateral. PMC
NF1 mutation (Neurofibromatosis type 1): increases risk of adrenal tumors with catecholamine excess. NCBI
SDHB mutation: linked with higher metastatic risk; careful lifelong follow-up is needed. Medscape
SDHD mutation: predisposes to PPGL; often multiple tumors; imprinting effects. PMC
SDHC mutation: rarer, but part of the same mitochondrial complex II gene group. PMC
SDHA mutation: less common; still a recognized PPGL gene. PMC
SDHAF2 mutation: affects assembly of the SDH complex; can predispose to PPGL. PMC
TMEM127 mutation: tumor-suppressor pathway; usually adrenal tumors. PMC
MAX mutation: often adrenal and bilateral; can be noradrenergic. PMC
EPAS1/HIF2A mutation: “pseudohypoxia” signaling; may produce noradrenergic or dopaminergic tumors. PMC
EGLN1 (PHD2) mutation: also in the hypoxia pathway; increases PPGL risk. PMC
FH mutation: Krebs cycle gene; linked to aggressive disease in some reports. PMC
KIF1Bβ mutation: rare susceptibility gene reported in PPGL. PMC
MDH2 mutation: rare metabolic gene linked to PPGL. PMC
Somatic (tumor-only) mutations: not inherited but acquired in the tumor; can drive growth. ScienceDirect
Family history of PPGL: suggests a hereditary mutation even if the specific gene is unknown. PMC
Chronic hypoxia states (e.g., cyanotic heart disease, high altitude): may stimulate hypoxia pathways involved in PPGL. Nature
Male sex in SDHB families: some series suggest greater metastatic risk; genetics matter more than sex. (Inference from genetic cohorts; risk varies.) Oxford Academic
Age under 45 with PPGL: higher chance of a germline mutation compared with late-onset sporadic cases, so genetics is often checked. PMC
Symptoms
High blood pressure (sustained or in attacks): too much catecholamine tightens blood vessels and raises pressure. Many patients have paroxysmal “spells.” NCBI
Severe headache: sudden vessel tightening and pressure spikes trigger throbbing headaches. NCBI
Palpitations or fast heart rate: adrenaline speeds the heart, causing pounding or irregular beats. NCBI
Excessive sweating (diaphoresis): the body’s “fight or flight” response over-activates sweat glands. Wikipedia
Anxiety, panic, tremor: adrenaline makes the nervous system overactive and shaky. NCBI
Pallor or flushing episodes: fast vessel changes in the skin cause color swings. Wikipedia
Weight loss: long-term hormone excess raises metabolism and reduces appetite. Wikipedia
Chest pain or shortness of breath: blood pressure surges strain the heart; rarely, stress cardiomyopathy occurs. NCBI
Abdominal or back pain: from a growing adrenal mass pressing nearby tissues. NCBI
Nausea or vomiting: sudden hormone spikes upset the gut and brain centers for nausea. Wikipedia
Constipation: noradrenaline slows gut movement in some patients. Wikipedia
Light-headedness when standing (orthostatic symptoms): blood vessels fail to adjust normally after big hormone swings. Wikipedia
High blood sugar: catecholamines make the liver release glucose and block insulin action. Medscape
Vision changes (rare, in crises): severe hypertension can affect the retina or cause headaches with visual aura. NCBI
Bone pain, cough, or weight loss that worsens: may signal spread to bone or lungs in malignant disease. Medscape
Diagnostic tests
A) Physical examination
Resting blood pressure and heart rate (during and between spells): very important first clues; pressure may be persistently high or spike in attacks. NCBI
Repeat readings across visits: shows variability and surge patterns typical of PPGL spells. NCBI
Orthostatic vital signs (lying → standing): checks for dizziness and abnormal blood pressure drop after surges or medication; done carefully. Wikipedia
Skin, eyes, and thyroid/neck check: looks for sweatiness, pallor, tremor, and features of related syndromes (e.g., MEN2 with thyroid disease). NCBI
Abdominal exam: sometimes a large adrenal mass or tenderness is found, though many tumors are not palpable. NCBI
B) Manual or bedside functional tests
These are clinic-performed assessments or special procedures that complement labs/imaging. They must be used judiciously.
Home or clinic blood-pressure diary: documents the pattern of spikes and symptom triggers; helps target lab timing. NCBI
Ambulatory 24-hour blood pressure monitoring (ABPM): tracks day–night pressure swings and paroxysms that fit PPGL. NCBI
Orthostatic vitals protocol (formalized): repeated sets over time quantify autonomic changes linked to catecholamine excess. Wikipedia
Clonidine suppression test (CST): used only when plasma normetanephrine is borderline; clonidine should suppress sympathetic nerve activity but not tumor secretion—so failure to suppress supports PPGL. Not for patients on certain drugs. This is not a first-line test. Oxford AcademicARUP Consult
Glucagon stimulation test (historical, rarely used): can provoke dangerous pressure spikes and is not recommended because sensitivity is poor; largely replaced by CST. PMC
C) Laboratory and pathological tests
Plasma free metanephrines: first-line test; very sensitive. The patient rests quietly before the draw. Markedly elevated results strongly suggest PPGL. Oxford Academic
24-hour urinary fractionated metanephrines and catecholamines: useful confirmatory test; very specific when clearly elevated. Medscape
Plasma 3-methoxytyramine (3-MT): detects dopamine-producing tumors and can aid in finding aggressive disease, especially with SDHx mutations. NCBI
Chromogranin A (CGA): a neuroendocrine marker that supports the diagnosis when elevated, though not specific. Pheo Para Alliance
Basic labs for complications: glucose (often high), electrolytes, kidney function, and blood count to assess end-organ effects. Medscape
Tumor histology after surgery (if resected): classic “zellballen” nesting pattern; immunostains (chromogranin, synaptophysin; S100 in sustentacular cells). Risk scores (e.g., PASS/GAPP) estimate aggressive behavior but do not define malignancy. Oxford Academic
Germline genetic testing panel: many patients have an inherited variant; results guide follow-up, family screening, and imaging choices. PMC
D) Electrodiagnostic and physiologic monitoring
Electrocardiogram (ECG): looks for arrhythmias, ischemia, or stress cardiomyopathy during hypertensive spells. NCBI
Holter monitor (24–48 h ECG): captures rhythm problems during intermittent attacks. NCBI
Ambulatory blood-pressure monitor (noted above) plus symptom diary: correlates heart rhythm, pressure spikes, and symptoms to support laboratory diagnosis. NCBI
E) Imaging tests (for localization and staging)
Cross-sectional imaging
Adrenal MRI or CT: first imaging after biochemical proof; MRI is excellent for adrenal masses; CT helps stage chest/abdomen/pelvis. Oxford Academic
Functional (molecular) imaging
¹²³I-MIBG scintigraphy/SPECT: targets norepinephrine transporters; useful especially when considering MIBG therapy or when PET is unavailable. Journal of Nuclear Medicine
⁶⁸Ga-DOTATATE PET/CT: often more sensitive than MIBG for many PPGLs, especially with SDHx mutations and for metastatic mapping. Some lesions can be DOTATATE-negative, so choice is individualized. PMCJournal of Nuclear MedicineOxford Academic
¹⁸F-FDG PET/CT or ¹⁸F-DOPA PET/CT: complementary in aggressive or SDHB-related disease (FDG) or in certain biochemical phenotypes (DOPA). Choice depends on genes and prior scans. Journal of Nuclear Medicine
Why imaging matters:
To find the adrenal tumor, check both glands, and stage spread to bone, liver, lung, and nodes. Up to 15–25% of PPGLs can be metastatic; careful baseline staging and lifelong follow-up are advised in guidelines and consensus statements. nanets.net

Immunity-booster / regenerative / stem-cell” drugs—
There are no approved “stem-cell drugs” for malignant adrenal medulla tumors, and no proven immune-boosting medication that safely improves outcomes outside clinical trials. What is used:
Checkpoint inhibitors (e.g., pembrolizumab, +/- nivolumab) – investigational or selective use; responses are modest; best within trials; monitor endocrine side effects closely. PubMedMDPI
HIF-2α inhibitor (belzutifan) – targeted for VHL-pathway PPGL in selected patients per 2025 approval (molecularly defined). NCCN
Anti-angiogenic TKIs (sunitinib, cabozantinib) – not immune “boosters” but do change the tumor micro-environment and can be combined with immunotherapy only in trials. PubMed+1
Somatostatin analogs & PRRT (^177Lu-DOTATATE) – can modulate tumor-immune interactions but are primarily targeted radionuclide therapies. ESMO
AZEDRA® (iobenguane I-131) – targeted radiotherapy; not immune-boosting. Drugs.com
Clinical-trial vaccines/combination IO – experimental only; ask your team about open trials. Frontiers
Surgeries
Laparoscopic adrenalectomy
Procedure: minimally invasive removal of adrenal tumor (transperitoneal or retroperitoneal).
Why: standard for most localized adrenal pheochromocytomas; faster recovery if no local invasion. PubMedScienceDirectOpen adrenalectomy (en-bloc when needed)
Procedure: open operation with wider margins if tumor is large, invasive, or involves major vessels.
Why: better exposure and control when cancer extends beyond gland. PubMedMetastasectomy / cytoreductive surgery
Procedure: remove selected metastases (liver, lung, lymph nodes, bone) when feasible.
Why: symptom relief (less catecholamine output), disease control in carefully selected cases (multidisciplinary decision). NanetsResection of extra-adrenal paraganglioma
Procedure: remove sympathetic paraganglioma causing excess hormones or mass effect.
Why: control hormones and prevent complications (often staged with alpha-blockade). Oxford AcademicVascular reconstruction or vena cava thrombectomy (selected cases)
Procedure: open surgery to remove tumor thrombus or reconstruct invaded vessels.
Why: restore blood flow and enable complete resection when invasion occurs. SAGES

FAQs
Is “malignant pheochromocytoma” curable?
If all visible disease can be removed and there is no spread, cure is possible. With metastases, long-term control is the goal using surgery, targeted radiation (AZEDRA/PRRT), and TKIs. Drugs.comESMOWhy do I need alpha-blockers before surgery?
They prevent dangerous BP spikes when the tumor is touched. Beta-blockers come after alpha-blockers if needed. Oxford AcademicHow long is pre-op prep?
Often about 1–2 weeks (sometimes longer), with a high-salt/high-fluid plan to refill blood volume. FrontiersPheo Para AllianceWhat if surgery isn’t possible?
Options include AZEDRA (if MIBG-avid), PRRT (if SSTR-positive), TKIs (sunitinib, cabozantinib), chemotherapy (CVD), or clinical trials. Drugs.comESMOPubMed+1Wiley Online LibraryDo supplements cure PPGL?
No. They may help symptoms (sleep, nausea) but can interact with cancer drugs—always ask your team. American Cancer SocietyIs immunotherapy a game-changer here?
Single-agent PD-1 therapy shows modest activity; best in trials or selected patients. PubMedWhich scan is best?
Choice depends on genetics and tumor behavior: DOTATATE, FDOPA, or FDG PET plus CT/MRI. Your team picks based on pattern. Oxford AcademicWill I always have high BP?
Good blockade and tumor control can normalize BP; some people still need long-term BP meds. FrontiersDo I need genetic testing?
Yes—recommended for all patients; it affects screening and family care. NanetsCan I exercise?
Yes—low-to-moderate and guided; avoid intense bursts until cleared and on blockade. (Mind your BP/HR.)Are there foods I must avoid?
Some people react to aged cheeses, certain wines, soy, chocolate; note your triggers and avoid stimulants and unreviewed supplements. Mayo ClinicAmerican Cancer SocietyWhat’s the role of PRRT?
For SSTR-positive progressive disease, PRRT can control growth; your scans decide eligibility. ESMOWhat’s AZEDRA?
A targeted radioactive drug (^131I-MIBG) for MIBG-avid, unresectable/metastatic PPGL; given in two therapeutic doses ~90 days apart. Drugs.comDo TKIs raise blood pressure?
Often yes—your team will monitor and treat BP while on sunitinib or cabozantinib. PubMed+1How often will I be followed?
Usually lifelong: periodic metanephrines and imaging tailored to your genetics and prior treatment. Oxford Academic
