We present an unusual case of radiation‐induced subacute cutaneous lupus erythematosus (SCLE) occurring in a patient with non‐Hodgkin lymphoma. Dermatologists should be aware of the ability of low‐dose radiation treatment to induce a first presentation or flare of SCLE, with the possibility of extension of disease outside of the radiation field.

Chronic skin disease is common in women of reproductive age. Although skin can improve or remain stable during pregnancy, it is also common for existing conditions to flare and for new conditions to develop. A small number of medications used to control chronic skin disease can potentially have adverse effects on the outcome of the pregnancy. This article forms part of a series on prescribing for pregnancy and highlights the importance of achieving good control of the skin disease prior to conception and during pregnancy. It emphasises the need for patient-centred, open and informed discussions around medication options to achieve good control. During pregnancy and breastfeeding each patient should be treated as an individual in accordance with the medications that are appropriate for them, their preferences, and the severity of their skin disease. This should be done through collaborative working across primary care, dermatology and obstetric services.
