[Familial multiple bilateral carcinoma of the kidney: clinical strategy and surgical approach].

A case of familiar bilateral multicentric RCC in a young woman is an ideal model to evaluate preoperative and intraoperative diagnostic and surgical tools in order to achieve two distinct goals: the oncologic radicalness and the renal function preserved. Radical bilateral nephrectomy, the renal hypothermia by perfusion of both kidneys, the bench high resolution sonography of parenchyma, the choose of one kidney suitable for conservative surgery, the resection of suspect lesions with intraoperative pathology, the reconstructive bench surgery, the autotransplantation, are the steps accurately performed with particular concern to eradication of all the tumoral lesions present in the kidneys. The results confirm that renal function has been preserved with this method. Radicalness should be appointed by a longlasting follow up. However, as it is discussed, conservative surgery, when accurately performed can give results not different from radical demolitive surgery. In this paper tools to improve diagnostic and therapeutic methods are described in order to increase the diagnostic accuracy and the therapeutic efficacy. The possibility that this multiple RCC can be a part of the abnormalities occurring in the Von Hippel-Lindau syndrome does not change the surgical approach, being the RCC the worst prognostic factor of the syndrome.

[Plasmocytoma of the testis. Description of a clinical case and review of the literature].

Extraskeletal involvement of the testis during multiple myeloma is a rare disease; primary extraosseus myeloma of the testis is even more unusual, and shows progression to typical multiple myeloma after orchiectomy in most cases. A case-report of a multiple myeloma with testicular involvement is discussed; radiotherapy was performed successfully, instead of surgery, but diffuse skeletal lesions showed progression in spite of chemotherapy. A short review of the literature on this subject is made.

[Persistent hyperplastic primary vitreous. Middle-term results of vitrectomy].

In this study, the authors present a homogeneous series of seven children suffering from persistent hyperplastic primary vitreous, in its complete anterior and posterior form. These children were operated by pars plana lensectomy and vitrectomy. The surgical operation was beneficial in every case: not only were there no complications, but the operation also prevented progression towards neovascular glaucoma, vitreous hemorrhages and phtisis bulbi. In addition, one of the benefits of this technique was esthetic, with the disappearance of leucocoria, the occasional correction of strabismus and the reduction in microphthalmos. Visual recovery can be surprisingly good, in the absence of any associated retinal malformation.

Complications of radial keratotomy: eyes with keratoconus and late wound dehiscence.

BACKGROUND: Radial keratotomy requires a thorough preoperative examination, including photokeratography, to detect early keratoconus. METHODS: We compared, by light and transmission electron microscopy, the healing process of corneas from two patients after radial keratotomy. RESULTS: Clinically, one patient had a keratoconus and gained no visual benefit from the radial keratotomy. The other patient had a spontaneous corneal perforation at one incision and a hypopyon. Histological studies showed a prolonged healing process in both eyes, with a persistent epithelial plug. Bowman's layer was also interrupted and retracted in both eyes. The inflamed cornea had deep neovascularization. CONCLUSIONS: These observations imply that 2 years after surgery, wound healing and, therefore, refraction is not stable. The results show the inappropriateness of radial keratotomy performed on eyes with keratoconus, with the possible risk of delayed corneal perforation.

Undifferentiated granulocytic sarcoma: a case with epidural onset preceding acute promyelocytic leukemia.

This study reports a case of granulocytic sarcoma that developed in the epidural zone 25 days before clinical evidence of an acute promyelocytic leukemia. The case presented the diagnostic difficulties that are common to all aleukemic granulocytic sarcomas. Moreover, it highlights the very rare association between granulocytic sarcoma and acute promyelocytic leukemia, which is far from being explained.
