Radiation-induced morphea of the breast-A case series.

Radiation-induced morphea (RIM) is a rare but recognized late complication of radiotherapy. It was first described in 1905, not long after the initial discovery of X-rays by Roentgen. Characterized by the deposition of excess collagen in the dermis, it results in thickening of the skin. Its frequency is approximately 2 in 1000. We present a series of three cases involving patients receiving radiotherapy treatment for breast cancer, each of which subsequently developed RIM. Because of its rarity, RIM is often misdiagnosed as infection or metastatic disease. This can lead to delayed diagnosis and treatment, leading to poorer outcomes such as chronic pain issues. Early dermatological involvement and tissue sampling to examine histopathological features can avoid this, leading to better care and improved results. A variety of treatment options are available, ranging from topical to systemic, with early induction more likely to result in a positive response.

Porokeratotic adnexal ostial nevus: A paradigm of cutaneous mosaicism.

Porokeratotic adnexal ostial nevus (PAON) is a term encompassing porokeratotic eccrine ostial and dermal duct naevus (PEODDN) and porokeratotic eccrine and hair follicle naevus (PEHFN). We present the case of a 7-year-old girl who presented with hyperkeratotic verrucous papules in a blaschkolinear distribution on the sole of her left foot.

Pregnancy-associated breast cancer: evaluating maternal and foetal outcomes. A national study.

PURPOSE: Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during the gestational period (gp-PABC) or in the first postpartum year (pp-PABC). Despite its infrequent occurrence, the incidence of PABC appears to be rising due to the increasing propensity for women to delay childbirth. We have established the first retrospective registry study of PABC in Ireland to examine specific clinicopathological characteristics, treatments, and maternal and foetal outcomes. METHODS: This was a national, multi-site, retrospective observational study, including PABC patients treated in 12 oncology institutions from August 2001 to January 2020. Data extracted included information on patient demographics, tumour biology, staging, treatments, and maternal/foetal outcomes. Survival data for an age-matched breast cancer population over a similar time period was obtained from the National Cancer Registry of Ireland (NCRI). Standard biostatistical methods were used for analyses. RESULTS: We identified 155 patients-71 (46%) were gp-PABC and 84 (54%) were pp-PABC. The median age was 36 years. Forty-four patients (28%) presented with Stage III disease and 25 (16%) had metastatic disease at diagnosis. High rates of triple-negative (25%) and HER2+ (30%) breast cancer were observed. We observed an inferior 5-year overall survival (OS) rate in our PABC cohort compared to an age-matched breast cancer population in both Stage I-III (77.6% vs 90.9%) and Stage IV disease (18% vs 38.3%). There was a low rate (3%) of foetal complications. CONCLUSION: PABC patients may have poorer survival outcomes. Further prospective data are needed to optimise management of these patients.

Novel agents for atopic dermatitis in patients over 50 years of age: A case series.

Lan et al recently highlighted the under-representation of older adults in clinical trials of systemic therapies for atopic dermatitis (AD). Late-onset AD is increasingly recognized in older adults. Spontaneous remission is uncommon with this phenotype. Existing drug treatments such as corticosteroids, methotrexate, ciclosporin, and azathioprine are complicated by adverse effects including increased malignancy risk, immunosuppression in the context of immunosenescence, and drug interactions in the setting of polypharmacy. A case series is presented of seven patients over 50 years of age with AD who were prescribed dupilumab or tofacitinib or upadacitinib for at least 6 months. All patients were clear or almost clear (investigator global assessment score 0/1) after 1 month of therapy. No significant adverse events were seen. This case series provides preliminary evidence about the safety and efficacy of these novel drugs for AD in older adults. Further studies with higher numbers of participants are needed to obtain real-world evidence for these drugs in older adults, given the limited data in clinical trials.
