ABSTRACT
Abstract: 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.

Anal melanoma is a rare aggressive disease, representing 0.4% to 1.6% of all melanomas and 1% of tumors of the anal canal. Its diagnosis is complex and in most cases is made in later stages with diffused disease, which contributes to its poor prognosis. Due to its low incidence, most studies are based on case reports and there is no consensus on the best diagnostic and therapeutic course of treatment. As a rule, the cure rate is low and the expected 5-year survival is 20%. As a consequence, therapy should be individualized, evaluated on a case-by-case basis, aiming locoregional control to provide better quality of life for the patient.
