Scleroderma-like cutaneous sclerosis has been reported as a rare adverse reaction to several drugs, including the chemotherapeutical agent paclitaxel, used in therapeutic regimens for several malignancies. The sclerosis is usually limited to the skin, most commonly presenting in the lower limbs after weeks to months of therapy but is often refractory to treatment and progresses even after discontinuation of the offending agents, with significant resulting morbidity. We report a rare case of severe cutaneous sclerosis secondary to chemotherapy with nab-paclitaxel and gemcitabine, which did not respond to treatment and led to discontinuation of chemotherapy.

Objectives: To set the goals, define criteria and unmet needs in UV diagnosis and differential diagnosis with CSU, and explore the possibility of coexistence of both diseases.
Methods: Thirteen experts experienced in UV research participated in a Delphi survey of European Academy of Allergy and Clinical Immunology taskforce.
Patients submitted to radiotherapy for tinea capitis in childhood have an increased incidence of scalp basal cell carcinomas (BCCs) but also of other neoplasms, namely, follicular tumors. In a cohort of such patients, we also found a high incidence of infundibulocystic BCCs, an otherwise rare variant. We thus hypothesized that postradiotherapy BCCs could be more prone to display follicular differentiation.

Post-radiotherapy BCCs are often multiple, and it has been suggested that they display more aggressive features. Our main objective was to study the clinicopathological aspects of post-radiotherapy BCCs to evaluate their biological behaviour and identify features that may differ from other BCCs.
