Neoplastic Implications in Patients Suffering from Hidradenitis Suppurativa under Systemic Treatments

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory skin disease of the apocrine glands. It typically involves the axillary, submammary, genital, inguinal, perineal, and perianal regions. The development of abscesses, sinus tracts, and scars can lead to pain, scarring, disfigurement and decreased quality of life. HS is associated with a wide range of comorbidities. Several studies of co-occurrence of HS and nonmelanoma skin cancer suggest a causal relationship. In an attempt to assess the link between HS and cancer, we performed a systematic review of the current scientific knowledge through a PubMed-based literature search. Results show that HS could be associated with an overall risk of cancer and numerous specific cancers such as: nonmelanoma skin cancer (NMSC), hematologic malignancies, and metastatic cancer. Among NMSC, squamous cell carcinoma (SCC) is considered the most common complication arising in long-standing HS. Based on our review, we suggest that cautious surveillance and active intervention may be warranted in patients with HS. Moreover, an age-appropriate cancer screening should be offered to all patients, especially those who developed HS later in their life or in long-standing moderate to severe HS with multiple comorbidities.

Hypofractionated radiotherapy for nonmelanoma skin cancer during the COVID-19 pandemic: experience in 31 cases

As a result of the coronavirus disease 2019 (COVID-19) pandemic, radiation therapies have been modulated to reduce the risk of infection during outpatient activities and hypofractionated regimens or radiotherapy delay for nonmelanoma skin cancer (NMSC) were suggested. Hypofractionated radiotherapy not only may confer no disadvantage in regard to outcome when compared to a more protracted schedule but might also reduce the risk of infection. We report the experience of a dermatologic radiation therapy department concerning a group of patients with a diagnosis of NMSC selected for a radiation treatment plan aimed to minimize the number of their accesses to our department.
