RESUMO
Myiasis refers to Diptera larvae infesting vertebrate animals. There are two forms of the disease: primary and secondary. In primary myiasis, fly larvae invade and develop in healthy tissue; in secondary myiasis, flies lay their eggs in skin ulcerations, and the larvae develop in tissue necrosis products. Furuncular myiasis is a type of primary myiasis. Treatment for it consists of techniques such as the production of localized hypoxia to force the emergence of the larvae, and mechanical or surgical removal of the maggots. These techniques, however, are painful and often unsuccessful. We propose a new technique for extraction of myiasis larvae, which might facilitate the surgical procedure and constitute a virtually painless and aesthetic option for the patient.

Parasitic infection of the breast is rare, especially in cases of cysticercosis. This disease is acquired by ingestion of tapeworm eggs in contaminated food and water supplies or from hands improperly washed after a bowel movement. Diagnosis is usually made incidentally. We report a patient with cysticercosis of the breast. The patient was a 63-year-old woman who had no clinical manifestations, but cysticercus was observed to cause calcifications detected by mammography. Computed tomography demonstrated brain lesions. A definitive diagnosis of cysticercosis was made by demonstration of characteristic calcified larvae. The definitive diagnosis was confirmed by excisional surgery.

A case of a pseudoneoplastic lesion of the breast clinically and sonographically suggestive of a fibroadenoma is reported. Excisional biopsy revealed the nodule was an inflammatory process consequent to infection by Schistosoma mansoni.

Five patients with breast myiasis underwent mammography, and three also underwent ultrasonography (US). Mammography revealed indistinct masses in all patients, with associated pairs of microcalcifications in three. US showed each larva as a fusiform hyperechoic mass surrounded by a hypoechoic halo, which included larval movement in one patient. These imaging features of breast myiasis facilitate correct diagnosis.

We report the case of a 63 years old woman with a left mammary hidatd cyst. The patient presented with a left painless mammary mass of four months evolution. Mammography showed a dense image of 9 cm in the left breast. Ultrasound showed a solid and heterogenous lesion. The tumor was excised under general anesthesia. The initial macroscopic inspection showed a tumor with a well defined fibrous capsule filled with a grayish material that contained membrane debris. The pathological study confirmed the diagnosis of a hydatid cyst
