A Caucasian female patient in her 90s was referred to the department of plastic and reconstructive surgery for surgical removal of a large invasive squamous cell carcinoma on the anterior chest wall. A skin biopsy prior to the referral indicated that the tumour was moderately differentiated. The patient suffered from severe congestive heart failure with a mechanical valve prosthesis and atrial fibrillation, and was therefore treated with anticoagulants. Hence, a surgical procedure would be hazardous. Therefore, other treatment options were considered. The principal aim was to reduce the amount of tumour tissue to an appropriate size suitable for later excision with primary wound closure. After interdisciplinary discussions, curettage and electrodessication combined with photodynamic therapy was judged the best alternative treatment in this case. At the 1.5 years follow-up after the intervention there was no indication for further surgery. The patient was at that stage content with the treatment and its outcome.
