RESUMO
BACKGROUND: Breast cancer patients may experience an increased chance of survival with adjuvant chemotherapy. However dermatologic adverse effects can cause major discomfort due to physical or cosmetic problems. This study aims to describe dermatologic complications in breast cancer patients during chemotherapy. METHODS: This longitudinal prospective observational study included data on women with non-metastatic breast cancer whom were treated with AC-T protocol (anthracycline, cyclophosphamide, and taxane) adjuvant chemotherapy and consecutively enrolled during two years. The study was performed in an educational and tertiary referral center. The patients' information including age, body mass index (BMI), past medical history, and different dermatologic complications were collected for all participants. RESULTS: Of 190 enrolled women, all patients experienced alopecia, which occurred in 131 patients (68.9%) after the first cycle. Skin, mucosal, and nail involvement were respectively seen in 46 (24.2%), 51 (26.8%), and 86 (45.2%) cases. Cutaneous complications were observed mainly between the third and sixth chemotherapy cycles. Palmoplantar erythema and palmoplantar dysesthesia were the most common cutaneous complications. Dermatologic adverse effects were significantly more frequent in the patients with an underlying disease. CONCLUSION: These findings suggest that dermatologic adverse effects of adjuvant chemotherapy are common and could be induced by all components of AC-T regimen. These complications should be skillfully managed to increase patients' comfort.

Pruritus is among the most common complaints in the field of dermatology. It is also a disturbing symptom of many systemic disorders. Chronic pruritus (CP) refers to the cases of the symptom which last longer than 6 weeks. We conducted a prospective analysis of patients with generalized pruritus without primary skin lesions. All patients underwent primary evaluations and then were followed from 12 to 18 months for further evaluations. Of the 5,127 patients referred to our dermatology clinic, 49 patients with generalized pruritus without primary skin lesions were evaluated. Most of the patients (44%) were in the age group of 40-60 years and female (58%). The duration of pruritus was 37.04 ± 30.4 weeks. Fifty percent of the patients with generalized pruritus had a systemic cause of pruritus. The most common underlying diseases were thyroid disorders (16.67%), diabetes mellitus (12.5%), and malignancy (8.33%). There were no significant statistical differences among the patients in terms of their age, gender, and disease duration with the underlying diseases (P = 0.47, P = 0.99, P = 0.816, respectively). However, the average age of the onset of pruritus was 12 years earlier in the women regardless of the underlying diseases (P = 0.011). Based on the findings of the study, we recommend considering endocrine disorders and malignancies as the most common underlying diseases leading to chronic pruritus without primary skin lesions.
