Abstract

Objective:

To review our experience of managing patients with a dual diagnosis of metastatic cutaneous squamous cell carcinoma in the head and neck region and low-grade non-Hodgkin lymphoma. The secondary aim was to evaluate the utility of 18F-fluorodeoxyglucose positron emission tomography during diagnosis.

Methods:

Patients diagnosed with metastatic cutaneous squamous cell carcinoma of the head and neck and low-grade non-Hodgkin lymphoma, in a five-year period, were identified. Patient, tumour and treatment characteristics were identified. 18F-fluorodeoxyglucose positron emission tomography imaging was reviewed and correlated with histopathology findings.

Results:

Eight patients were identified. There was a delay in diagnosis of metastatic squamous cell carcinoma in two patients. 18F-fluorodeoxyglucose positron emission tomography differentiated metastatic squamous cell carcinoma from low-grade non-Hodgkin lymphoma with a sensitivity of 88.2 per cent and a specificity of 94.7 per cent. In 38 per cent of patients, compromises in management had to be made.

Conclusion:

The management of metastatic squamous cell carcinoma can be challenging in patients with low-grade non-Hodgkin lymphoma. 18F-fluorodeoxyglucose positron emission tomography can be useful in the diagnosis of metastatic squamous cell carcinoma in patients with low-grade non-Hodgkin lymphoma.
