Myiasis associated with penile carcinoma: a new trend in developing countries?
International braz j urol, 2017
The aim of this study is to report an unusual form of penile cancer presentation associated with myiasis infestation, treatment options and outcomes. Materials and Methods: We studied 10 patients with suspected malignant neoplasm of the penis associated with genital myiasis infestation. Diagnostic assessment was conducted through clinical history, physical examination, penile biopsy, larvae identification and computerized tomography scan of the chest, abdomen and pelvis. Clinical and pathological staging was done according to 2002 TNM classification system. Radical inguinal lymphadenectomy was conducted according to the primary penile tumor pathology and clinical lymph nodes status. Results: Patients age ranged from 41 to 77 years (mean=62.4). All patients presented squamous cell carcinoma of the penis in association with myiasis infestation caused by Psychoda albipennis. Tumor size ranged from 4cm to 12cm (mean=5.3). Circumcision was conducted in 1 (10%) patient, while penile partial penectomy was performed in 5 (50%). Total penectomy was conducted in 2 (20%) patients, while emasculation was the treatment option for 2 (20%). All patients underwent radical inguinal lymphadenectomy. Prophylactic lymphadenectomy was performed on 3 (30%) patients, therapeutic on 5 (50%), and palliative lymphadenectomy on 2 (20%) patients. Time elapsed from primary tumor treatment to radical inguinal lymphadenectomy was 2 to 6 weeks. The mean follow-up was 34.3 months. Conclusion: The occurrence of myiasis in the genitalia is more common in patients with precarious hygienic practices and low socioeconomic level. The treatment option varied according to the primary tumor presentation and clinical lymph node status.
Penile myiasis as a differential diagnosis for genital ulcer: a case report
The Brazilian journal of infectious diseases : an official publication of the Brazilian Society of Infectious Diseases, 2008
The genital localized myiasis is a rare zooparasitic dermatosis. This case reported to a penile myiasis by Dermatobia hominis larvae in a 62 year-old man, who is a retired military official from São Gonçalo city, Rio de Janeiro state, Brazil. This patient was guided to the sexually transmitted diseases (STD) clinic from Universidade Federal Fluminense (UFF) by professionals from a urology outpatient clinic of a public hospital from Rio de Janeiro state. The exam showed a 2 cm diameter nodular lesion with a hyperemic area in the glands penis that had arisen 20 days before the exam. It evolved in a favorable way after larvae removal, through previous local anesthesia and slight pressure in lesion's base with the extraction of the larvae. Penile myiasis is not a very frequent situation, although it must be considered as an option in differential diagnosis of genital infectious diseases, even among people of low economical level, as in the case presented.
Invasive Penile Carcinoma: A Review
Dermatologic Surgery, 2004
BACKGROUND. Penile carcinoma is an invasive epithelial tumor that may arise from penile skin or mucosa. OBJECTIVE. To review the pathogenesis and the clinical and histopathologic features of invasive penile carcinomas, with emphasis on current guidelines for their diagnosis and treatment. METHODS. Information available from the authors' clinical experience, review articles, case reports, clinical trials, and in vitro research studies identified from a computerized literature search on MEDLINE database and from Meetings' Abstract Books, including those from non-English literature, was considered. RESULTS. Penile cancer may develop de novo or in association with underlying factors. Conditions predisposing to the development of penile cancer are delineated. The diagnosis should be suspected by clinical findings and must be confirmed histo-

Penile tumours are an important problem of male health affecting physical, mental and sexual health. Penile tumours can be subdivided into benign and malignant lesions. Their knowledge is important to prevent mutilating surgery in benign lesions. On the other hand, early recognition of malignancies is important for improved prognosis, and preservation of function. The most important tumour by epidemiology and prognosis is penile cancer. In contrast, malignant melanoma, sarcomas and lymphomas are rare. Clinical symptoms, histopathology and treatment options are discussed. Best possible treatment needs an interdisciplinary approach.
Extensive myiasis infestation over a squamous cell carcinoma in the face. Case report
Medicina oral, patología oral y cirugía bucal, 2008
Human myiasis is a parasitosis found in tropical and underdeveloped countries. It usually affects the elderly, unhealthy and mentally disabled individuals. It is caused by dipterous that lay their eggs in necrotic or infected tissues, although areas of the body that are apparently healthy can also be affected. Frequently the fly deposits several eggs on the peripheral parts of scratches and wounds. The treatment of myiasis involves mechanical removal of the larvae with hemostatic pincers. Larvae rupture must be avoided. Application of topical ether or similar volatile substance is useful. Preventive approach measures, including basic health care, hygiene, access to primary health service, and safe water and drainage, are fundamental to prevent human myiasis. The authors present a case report of myiasis infestation over an extensive head and neck squamous cell carcinoma from a 72-year-old patient living in a rural area. Approximately 200 larvae were removed and the patient was taken ...

in the last ten years. Results. A total of 34 patients were diagnosed and treated. The mean age at presentation was 71.27 years. The mean time between symptoms and the first consultation was 12.54 months with a median of 6 months. The most common form of presentation was balanoposthitis (32%) and the most common site in our series was the glans. Partial penectomy was performed in 22 cases, total amputation in 8, and local excision in 3. Discussion. Carcinoma of the penis is a pathology which mostly affects elderly patients; in our series, the highest incidence was observed in patients in the group aged 75-84 years. The most common histological type was epidermoid carcinoma in its various forms of presentation. We recorded a mortality of 23%. Conclusion. Penile carcinoma is a rare pathology which affects elderly persons and is diagnosed late.
Case report: Urogenital myiasis in an adult male
Urology Case Reports, 2020
Urogenital Myiasis is rarely documented in developed countries, so epidemiological data are limited and often associated with travel to endemic regions. We report a Case of urogenital myiasis, unassociated with travel, in a 31 year old male. The patient presented to the emergency department after passing a larval fly during micturition. Pathologic examination of the initial urine sample confirmed the presence of living fly larvae and further evaluation was arranged with the urology department. The patient had no further episodes, and resolution was confirmed via urinalysis and cystoscopy. Several common risk factors were identified, including poor sanitation and hygiene.
