Pancoast Tumour (Superior Sulcus / Apical Lung Cancer) body chart — Illustrative, not diagnostic. Canva body chart for Pancoast Tumour (Superior Sulcus / Apical Lung Cancer).

The shoulder page you must know before you need it.

Illness script in one line: shoulder, scapular or medial arm pain with no mechanical cause, worse at night, unrelieved by rest or position, in a smoker or older adult, with hand weakness or numbness in a C8–T1 pattern and sometimes a drooping eyelid and small pupil on the same side.

Caseload frequency: rare. You may go a whole career without one, and you will absolutely see the presentation it hides inside — an unexplained shoulder.

The line that gets students

Classic teaching lists "normal shoulder imaging" under objective findings. Read that sentence again, because it is the trap.

A normal shoulder X-ray or ultrasound is what you'll be handed. It reassures the patient, it reassures the referrer, and it means nothing here — because the tumour is in the lung apex, not the shoulder.

"Normal shoulder imaging" doesn't mean it's clear. It means you imaged the wrong thing.

Pancoast tumour masquerading as musculoskeletal pain has been reported [1]. Read further: pulmonary pathology presenting as shoulder pain, written for physios [2], orthopaedic aspects and early diagnosis [3], shoulder pain as a diagnostic dilemma [4]. This is an old problem that keeps happening.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

On a red-flag pattern the subjective is not 70% — it is close to all of it. The examination confirms; the story is what saves the patient.

MAIN PROBLEM

"My shoulder's been aching for months and nothing helps." Often already seen someone. Often already had a scan. Often already been given exercises.

BODY CHART

Shoulder, scapular, or the medial (ulnar) side of the arm. C8–T2.
Ask them to trace it. Medial arm, medial forearm, into the little and ring fingers is not a rotator cuff pattern. The cuff refers to the deltoid insertion and rarely below the elbow.
± anterior chest wall or axilla.

BEHAVIOUR — this section decides the page

Feature	What it should look like	What this pattern looks like
Relationship to movement	Clear aggravating and easing positions	None that hold up. It doesn't behave mechanically.
Effect of rest	Eases	Unrelieved.
Night	Sore lying on it; position change helps	Wakes them, and no position helps.
Trajectory	Fluctuating, or slowly improving	Steadily worse.
Response to treatment	Something shifts	Nothing shifts.

One pearl applies directly: "not movement-provoked = not MSK until proven otherwise." Cross-link the cardiac and pulmonary referred pain page — the reasoning is identical.

HISTORY

Smoking — current, past, pack-years. Ask it as a number. Read further: lung cancer screening guideline [5], low-dose CT screening in a high-risk population [6]. You are not ordering it — but "ask your GP whether you're eligible for lung cancer screening" is inside your scope and it is a good sentence.
Weight loss, appetite, fatigue, cough, haemoptysis, breathlessness, hoarseness.
Age. Older, but not a rule.
Hand: dropping things, doing up buttons, grip changing.
Eye or face: has anyone said your eyelid looks lower? Do you sweat less on one side of your face?
What has already been done, and did any of it change anything? Failed treatment is data.

The delay is documented on both sides

Read further: patient and doctor delay [7], a delayed diagnosis missed by patient and clinician [8].

Nobody misses this because it's rare. They miss it because it looks treatable and someone kept treating it.

3 · HYPOTHESIS RANKING

The point of this page is that it should be ON the list, not top of it

Pattern	The discriminating feature
Rotator cuff–related shoulder pain	Load-related, painful arc, refers to the deltoid insertion, responds to something. Not C8, not nocturnal-unrelieved, not progressive.
Cervical radiculopathy (C8/T1)	Same distribution — this is the honest confusion. But: mechanical relationship, positive ULNT, relief with unloading or arm-overhead. Read further: cervicobrachialgia and Pancoast tumour [9].
Thoracic outlet syndrome	Postural, load-related, provoked by sustained overhead positions, no constitutional symptoms.
Adhesive capsulitis	True capsular pattern with PROM loss and a firm end-feel. Pancoast gives reduced ROM without a mechanical restriction.
Pancoast tumour	Non-mechanical, night-unrelieved, progressive, C8–T2, hand wasting, ± Horner's, smoker.
Cardiac or pulmonary referral	Exertional, or pleuritic with breathlessness. Its own page.
Metastatic disease, infection	Constitutional symptoms, cancer history.

The rule that runs this section

Every unexplained shoulder gets the non-mechanical question asked, and every shoulder with C8/T1 symptoms gets the hand and the pupils looked at. That costs you sixty seconds and it is the entire job.

4 · RED FLAGS — DON'T MISS THIS

Free forever. Safety is never behind a paywall.

On this page the red flags are the diagnosis.

Finding	What it means
Shoulder pain with NO reproducible mechanical pattern	The single most important finding. Not MSK until proven otherwise.
Night pain unrelieved by any position	Different from "sore lying on it". Ask specifically.
Progressive, despite treatment	Failed treatment is data. Escalate, don't intensify.
C8–T1 sensory or motor symptoms — medial arm, ring and little finger, grip loss	Lower trunk brachial plexus. Examine the hand.
Wasting of the hand intrinsics	Look at the first dorsal interosseous and the hypothenar eminence, both hands, side by side.
Horner's syndrome — ptosis and miosis on the same side	See section 5. And note it is also the sign of carotid dissection.
Smoking history, weight loss, cough, haemoptysis, hoarseness	Constitutional. Ask every time on an unexplained shoulder.
"Normal shoulder imaging"	Not a clearance. The chest has not been imaged.

The two sentences to hold

A shoulder that doesn't behave mechanically, doesn't settle at night, and doesn't respond to anything is a referral, not a rehab plan.

The referral is same-week. It is not conditional on failing another four sessions.

Any red flag: stop, escalate, and check it with your educator.

Guideline anchor

No Australian guideline for the physiotherapy recognition of this presentation.

The Australian anchor for when to investigate is Cancer Australia's Investigating symptoms of lung cancer: a guide for all health professionals (2020), which lists unexplained, persistent chest and/or shoulder pain lasting more than three weeks (earlier with risk factors) as a trigger for an urgent chest X-ray. The imaging anchor is the ACR Appropriateness Criteria for Horner syndrome (Dubey et al. 2025, PMID 41193044). The risk-profile anchor is the CHEST guideline and expert panel report on screening for lung cancer (Mazzone et al. 2021, PMID 34270968), with low-dose CT screening in a high-risk population reported in Lancet Oncology (Bhamani et al. 2025, PMID 40154514). The recognition anchor — and the most useful paper on this page for a physiotherapy student — is a report of pulmonary pathology recognised in a patient presenting with shoulder pain, published in Physiotherapy Theory and Practice (Brindisino et al. 2022, PMID 32459135), alongside a report of Pancoast tumour masquerading as musculoskeletal pain (Gadikota et al. 2025, PMID 40860246).

PubMed Source

The guidelines here govern imaging and screening decisions made by doctors. Nothing on this page is a treatment guideline, because the physiotherapy management of this condition is recognition and referral.
