The objective of this study is to describe the case of a patient presenting advanced epidermoid carcinoma of the penis associated to myiasis. A 41-year-old patient presenting with a necrotic lesion of the distal third of the penis infested with myiasis was attended in the emergency room of our hospital and was submitted to an urgent penectomy. This is the first case of penile cancer associated to myiasis described in the literature. This case reinforces the need for educative campaigns to reduce the incidence of this disease in developing countries.

Penile cancer is a rare neoplasia with low incidence in developed countries (0.1 - 0.9/100.000 in Europe and 0.7 - 0.9/100.000 in the United States). In developing countries, the incidence of this neoplasia is alarming with indexes that reach 2.9 - 6.8/100.000 in Brazil and 2 - 10.5/100.000 in India (1). Myiasis is defined as a disease caused by the infestation by larvae or maggots, of numerous species of flies (2). The occurrence of myiasis in the genitalia is rare. The objective of this article is to describe a case of myiasis in a patient presenting carcinoma epidermoid of the penis.
41 year-old patient came to the emergency room of our hospital presenting
with dehydration, fever, paleness and claiming of strong pain in the genital
region. On physical examination, we noticed an extensive necrotic lesion
affecting the distal third of the penis (Figure-1A). We have also observed
the presence of gross keratinizations in the lesion and an intense infestation
due to myiasis (Figure-1B). The patient was previously healthy and had
been hospitalized 2 years before to be submitted to a postectomy in another
hospital. At the time of postectomy, a suspicious lesion in the gland
was biopsied; however, the patient abandoned the treatment without knowing
the result of the biopsy.
is the infestation of the organs or tissues of host animals by the larval
stages of dipterous flies, usually known as maggots or grubs. The fly
larvae feed directly on the host’s necrotic or living tissue, or
in ulcerated mucosa and cavities (2). The most common form in men is in
the skin, where the species Dermatobia hominis is the most common. The
severity of the condition depends on the location and the degree of tissue
