Clinicopathological characteristics, long-term prognosis and follow-up recommendations of primary and secondary cutaneous angiosarcoma: A Danish nationwide population-based cohort study.

Background: The prognostic impact of subclassifying tumors as primary and secondary cutaneous angiosarcoma (cAS) in terms of the risk of local recurrence, metastasis, disease-specific mortality, and overall survival has not been extensively investigated in previous studies. This study aimed to characterize the clinicopathological features and estimate the 2-, 5-, and 10-year rates of local recurrence, metastasis, disease-specific death, and overall survival for patients with primary and secondary cAS, and to propose a follow-up recommendation for these patients.

Methods: All Danish patients diagnosed with cAS between 2000 and 2023 were included.

Atypical fibroxanthoma and pleomorphic dermal sarcoma: Local recurrence and metastasis in a nationwide population-based cohort of 1118 patients.

Background: The prognosis of patients with atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) remains uncertain and no standardized follow-up programs have been established.

Objective: To recommend a standardized follow-up program of patients with AFX and PDS based on nationwide long-term estimates of local recurrence and metastasis.

Methods: All patients with AFX and PDS in Denmark between 2002 and 2022 were included.

[Primary cutaneous sarcomas].

Primary cutaneous sarcomas are a heterogenous group of malignant soft tissue tumours arising in the dermal and subcutaneous layers of the skin. These tumours are rare and have a variety of clinical manifestations. They differ from deep soft tissue sarcomas in terms of prognosis, which for most types of cutaneous sarcomas is favourable.

[Dercum's disease].

Dercum's disease is a rare disease, which mainly affects women and has an unknown prevalence and aetiology. The disease is characterised by generalised obesity and more than three-month painful subcutaneous adipose tissue not responding to usual pain treatment. A suggested classi-fication of the disease includes four types: generalised diffuse, generalised nodular, localised nodular and juxta-articular.

Self-reported problems and wishes for plastic surgery after bariatric surgery.

In the affluent part of the world, there is an increasing occurrence of obesity with Body Mass Index (BMI) above 40, which has resulted in an increasing number of operations such as gastric bypass (GB). After massive weight loss there will often be a need for subsequent plastic surgical correction, since some of the patients will experience problems due to excess skin. Foreign studies estimate that ∼30% of all bariatric surgery patients will at some point seek plastic surgical correction of excess skin.
