[Primary retroperitoneal hydatid cyst]. / Quiste hidatídico retroperitoneal primario.

OBJECTIVE: To review the pathogenesis, clinical features and treatment of a rarely observed site of presentation of hydatid cyst. METHODS/RESULTS: A case of an isolated retroperitoneal hydatid cyst is presented. Diagnosis was based on the immunodiagnostic test and radiological examination. Treatment was by surgery. CONCLUSIONS: Isolated retroperitoneal hydatic cyst is rare. The abdominal mass is the most frequent sign, and less frequently, concomitant compressive syndrome. Diagnosis is based on the biological examinations, percutaneous puncture and radiological findings. Treatment is by surgery. Azoles are useful for intraoperative ruptured cysts and to reduce the risk of recurrence.

[Verrucous carcinoma of the penis: local excision with the Mohs micrographic technique]. / Carcinoma verrucoso de pene: exéresis local mediante técnica micrográfica de Mohs.

OBJECTIVES: We report on two cases of verrucous carcinoma of the penis that had been treated conservatively by local excision using the Mohs micrographic technique. METHODS/RESULTS: The clinical features, diagnosis and treatment of verrucous carcinoma of the penis are discussed. CONCLUSIONS: Local excision according to the Mohs micrographic technique may suffice in cases with non-invasive verrucous carcinoma of the penis. If the lesion involves the penile shaft, partial or total amputation of the glans penis is indicated, depending on the degree of involvement. Lymphadenectomy does not appear to be necessary since lymph node metastasis is rare.

[Uses of endoscopic video-camera in open surgery]. / Usos de la vídeo-cámara endoscópica en cirugía abierta.

OBJECTIVES: To describe a method to obtain images of open surgery at the lowest possible cost. The images provide useful information for patient records and teaching. METHODS: We have utilized a submersible endoscopic camera with no special features, close up lenses or automatic focussing device and a color printer. RESULTS: The quality of the images are similar to those obtained with a more sophisticated video camera. The pictures were processed with a video printer. CONCLUSIONS: We believe that using the endoscopic camera in open surgery is a low-cost alternative to the more sophisticated video camera systems.
