[Acquired lymphangiectases and breast cancer].

Acquired lymphangiectases represent superficial lymphatic dilatations caused by a wide range of processes. Many cases reported in the literature develop in patients with upper limb lymphedema secondary to mastectomy, radiotherapy, keloids or scleroderma. Clinically they consist of traslucent vesicles in a chronic lymphedematous area. Histologically they are characterized by the presence of dilated spaces with flattened endotelial cells in the papillary dermis. All these cases have a good prognosis and there have not been any reports of malignant transformation. We describe a 67-year-old woman that showed multiple papules along her left upper limb associated with lymphedema. She had undergone a mastectomy followed by radiotherapy fourteen years before due to a breast cancer. Laboratory and radiological exams were within normal limits. The cutaneous lesions showed characteristic clinical and histological features of lymphangiectases and they progressively resolve in several weeks without any treatment.
