Right Shoulder Pain due to Metastatic Lung Cancer: A case report

Frozen shoulder and risk of cancer: a population-based cohort study

Background:

Frozen shoulder might be a complication or a presenting symptom of cancer. We examined the risk of a cancer diagnosis after an incident diagnosis of frozen shoulder.

Methods:

We used prospectively collected data from Danish registries to identify patients with frozen shoulder during 1995–2013 and followed them for the development of cancer.

Results:

We observed 2572 incident cancers among 29 098 frozen shoulder patients. The expected number of incident cancers in the general population was 2434. The 6-month cumulative incidence of any cancer was 0.70%, corresponding to a standardised incidence ratio (SIR) of 1.38 (95% confidence interval (CI): 1.19–1.58). Risk increases were highest for lung cancer (SIR=2.19, 95% CI: 1.48–3.13), breast cancer (SIR=1.51, 95% CI: 1.02–2.15), and non-Hodgkin’s lymphoma (SIR=2.28, 95% CI: 1.09–4.20). The cumulative incidence of any cancer during the remainder of follow-up (>6 months to a maximum 18.9 years) was 24.8% with an SIR of 1.04 (95% CI: 1.00–1.08).

Conclusions:

Frozen shoulder might be an early predictor for a subsequent cancer diagnosis.

The Shoulder Pain due to Metastatic Breast Cancer -A Case Report-

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic neoplasm. However, metastatic cancer in the shoulder joint is difficult to diagnosis. We experienced a case in which a 46-year-old female patient complained of left shoulder pain and limited joint mobility, and these symptoms were due to metastatic breast cancer in the shoulder.
