Angiosarcomas are rare malignant tumours that arise from endothelial cells lining vascular channels, representing 0.04% of malignant neoplasms of the breast. Breast angiosarcomas (BAs) were first described by Schmidt in 1887, and may be primary or secondary to the pre-existing conditions. Primary BAs are more common in young women and present as a palpable mass. Secondary BAs arise in older patients, frequently 5-6 years after radiotherapy, and present as a rash.The authors describe the case of an 83-year-old woman with no history of thoracic radiotherapy or surgery. She had been observed for a breast nodule where biopsy revealed phyllodes tumour. The patient refused surgery and returned 2 years later because of an impressive increase in tumour volume and skin ulceration. She underwent mastectomy with local skin flaps. Histopathological result revealed high-grade angiosarcoma of 15×12 cm. There was follow-up without evidence of recurrence, after radiotherapy.

Adenoid cystic carcinoma (ACC) is a rare malignant neoplasm, arising from glandular tissues, found mainly in the head and neck. Generally, it presents insidiously but can behave aggressively making its course unpredictable. Surgery and adjuvant radiotherapy continue to be the cornerstone for its treatment. ACC remains extremely difficult to treat. The authors report a case of a 37-year-old woman with bloody rhinorrhea for 6 months. She was diagnosed with a left nasal cavity lesion that was biopsied, and the anatomopathological result showed ACC. The patient was submitted to a left extended maxillectomy, microsurgical reconstruction and radiotherapy.

Morbid obesity is a huge problem of the twenty-first century, mostly treated by bariatric surgery. The authors report the case of a patient with port site metastases from an unknown rectal adenocarcinoma when bariatric surgery took place. Implants in the site of the subcutaneous access port to the band are problematic, particularly in patients with occult intra-abdominal malignancy. This case underlines the importance of preventive measures to avoid cell implant in port sites in benign such as malignant diseases.
