[Radiation-induced morphea-an overview]

Radiation-induced morphea is a fibro-inflammatory remodelling process of the subcutaneous connective tissue caused by ionising radiation, most commonly in the context of breast cancer treatment. The underlying pathomechanisms and putative risk factors are unknown. Therefore, misdiagnosis and inappropriate treatment pose a significant problem in the care of those patients.

The aim of the study was to provide an overview as well as guidance for the diagnosis and treatment of radiation-induced morphea based on current case reports and review articles.

Radiation-induced morphea is a rare condition that represents an interdisciplinary challenge for (gynaecological) oncology, radiotherapy and dermatology. Frequent misdiagnoses include infection (erysipelas), cancer recurrence or radiation dermatitis. Early histological diagnosis and the initiation of anti-inflammatory therapy using topical glucocorticoids or calcineurin inhibitors in combination with phototherapy and/or methotrexate are the most relevant success factors for an adequate clinical response.
