[Segmentary testicular infarction]. / Infarto segmentario de testículo.

OBJECTIVE: A new case of segmental testicular infarction is reported. METHODS: A 52-year-old man presented to the emergency department with severe pain in the left testicle over a few days period. Physical examination revealed a tender induration in the upper pole of the left testicle. Beta-human chorionic gonadotropin and alpha-fetoprotein were normal. Sonography demonstrated a poorly-defined, hypoechoic, 13 mm lesion. On power Doppler sonography, the hypoechoic area appeared completely avascular in contrast to the rest of the testicle. RESULTS: Since testicular tumor was the initial diagnosis, the patient underwent a left radical orchiectomy. Pathological study revealed a focal testicular infarction, without signs of malignancy or vasculitis. CONCLUSIONS: Segmental testicular infarction is usually diagnosed after radical orchiectomy, performed when testicular tumor is suspected. On certain occasions Doppler ultrasound and magnetic resonance imaging findings suggested a segmental testicular infarction. However, if tumor cannot be entirely excluded, exploratory surgery is necessary.

[Urinary stone in a Bricker's ileal conduit]. / Litiasis en conducto urinario tipo Bricker.

OBJECTIVES: To report one case of urinary stone as a relatively frequent complications of urinary diversion using bowel loops. METHODS: We perform a short bibliographic review using the case report format. RESULTS: Stone formation in Bricker's type urinary diversion is secondary to various factors such as urinary stasis, bacteriuria, presence of intestinal mucus, metallic sutures, metabolic disturbances, etc. CONCLUSIONS: Periodic control by radiological studies is recommended due to the high frequency of this complication in patients with urinary diversion. Treatment is usually conservative or minimally invasive, being surgery reserved for those cases in which stone extraction is not safe using other methods.

[Necrosis of the penis in a diabetic patient: presentation of a case]. / Necrosis de pene en paciente diabético, presentación de un caso.

OBJECTIVES: To present a short review of the diagnosis, clinical features, and treatment of male genitalia necrosis under the format of a case report. METHODS: We review the case of a diabetic patient without good blood sugar control who suffered from various diabetic complications diagnosed and treated at our hospital of a penile necrosis. We perform a bibliographic review about male genitalia necrosis regarding its etiology, diagnosis and treatment. RESULTS: Male genitalia necrosis is a rare disease but it is associated with high morbidity and mortality. The present case was diagnosed at the emergency room at our Hospital. Conservative treatment with antibiotic therapy and corticosteroid ointments was undertaken successfully. CONCLUSIONS: To perform an etiologic evaluation of the necrosis (dry or infectious) is important to select the right treatment. The high mortality of these diseases requires a precise and early diagnosis, since this influences the good or bad evolution of the disease.

[Fixed drug-induced exanthema of the glans]. / Exantema fijo medicamentoso en glande.

OBJECTIVES: To claim attention on an relatively frequent adverse reaction to drugs affecting genitalia, therefore a reason for consultation to the Urology Department. METHODS: We report a clinical case and a bibliographic review of this disease. RESULTS: Fixed drug eruption is a cutaneous eruption secondary to drug intake that appears every time the drug is taken, always in the same location, being more common in hands and feet. The course of the disease is usually progressive with increasing number of lesions after each dose of drug taken. CONCLUSIONS: Relapsing lesions in the same spot is key for the proper diagnosis of this eruption. To forbid causing drug intake is the treatment of choice, although it may be necessary to administer local or even oral corticosteroids.

[Acute scrotum secondary to testicular tumor]. / Escroto agudo secundario a tumor testicular.

OBJECTIVE: To report a case of testicular tumor, classified as seminoma, with a very uncommon form of presentation since it presented as acute scrotum. METHODS: The clinical features, treatment and outcome of this uncommon condition are presented. RESULTS: A review of the literature showed that this form of presentation is rare although in the present case it is impossible to determine if testicular inflammation was due to tumor necrosis or infection from the associated hydrocele. CONCLUSIONS: Testicular tumor should be considered in all male patients aged 20 to 35 years with acute scrotum.
