Resumo
Background: Mammary neoplasms are frequent in dogs, and surgical excision by radical unilateral mastectomy is thefirst-choice treatment for most cases. Typically, inguinal lymphadenectomy is performed during mammary inguinal excision, whereas axillar lymphadenectomy is performed using dyes to guide surgical dissection and avoid iatrogenic trauma.This study reports the case of a bitch that underwent axillar lymphadenectomy and regional mastectomy. In this way, thiswork has the objective of reporting the case of a bitch referred to mastectomy and lymphadenectomy, which presentedcomplications due to the use of 1% methylene blue.Case: A 15-year-old female intact poodle weighing 6.2 kg presented with mammary nodules. Cytological examinationconfirmed malignant neoplasm in the mammary gland classified as Grade II (World Health Organization). Radical unilateralmastectomy and regional lymphadenectomy were performed. The surgical procedure involved intradermic injection of 0.5mL of sterile 1% methylene blue solution around the right cranial thoracic mammary gland divided in four sites beforeskin incision. Following right axillar lymphadenectomy, instead of radical unilateral mastectomy, regional mastectomywas performed in two ulcerated nodules at the right cranial abdominal gland to shorten the surgery time after the bitchdemonstrated severe trans-operative hypotension. The bitch was monitored during anesthetic recovery and was dischargedafter stabilization. At fourteen days after surgery, the patient was re-examined. Increased volume and pain in the mammaryglands of both chains were observed. In addition, a whitish liquid secretion was noted primarily from the thoracic caudalleft and thoracic cranial right mammary glands. The last mammary gland also presented a periareolar black area where thedye was applied. Progressive remission of the clinical signs was observed after therapy with...(AU)
