Skin cancer in organ transplant recipients
The high risk of skin cancer after organ transplantation is a major clinical challenge. Taking advantage of a high-quality national cancer registry, we have studied long-term changes in the risk of cutaneous squamous cell carcinoma after organ transplantation in Norway.

Fractional laser-assisted daylight photodynamic therapy for multiple actinic keratoses of the scalp in organ transplant recipients: a randomized half-side comparative trial
Organ transplant recipients (OTRs) are at high risk of skin cancer, especially squamous cell carcinoma (SCC). SCC often develops in the area of field cancerization, areas exposed for chronical sun damage and multiple actinic keratoses (AK). It is of high clinical value to treat precancerous lesions such as AK among OTRs. In order to evaluate more effective treatment of AKs/field cancerization in OTRs we set out a randomized half-side comparative trial to investigate the effect of pre-treating the skin with ablative, fractional carbon dioxide laser before daylight PDT.

Folliculotropic mycosis fungoides
Folliculotropic mycosis fungoides (FMF) is a variant of mycosis fungoides (MF) with distinct clinical and histopathological features. Folliculotropism may suggest that antigen-stimulation by particular antigens present in the hair follicle contribute to the pathogenesis.

Validation of staging systems for cutaneous squamous cell carcinoma: a population-based, nested case-control study
In this study, we aim to determine the rate of metastasis in cutaneous squamous cell carcinoma (cSCC) in Norway, by using high-quality population-based data. Also, we aim to assess the impact of reported risk factors for metastasis and to externally validate three existing current cSCC staging systems for their reproducibility and practicality.
