[Endometriosis of the bladder muscular layer as a cause of acute abdomen]. / Endometriosis de la capa muscular vesical como causa de abdomen agudo.

OBJECTIVES: A case of acute abdomen arising from endometriosis of the bladder is described. The rarity of this condition prompted us to report on the present case and the problems encountered in making the differential diagnosis. METHODS/RESULTS: A patient with endometriosis of the muscle layer of the bladder mimicking acute gynecological abdomen is described. CONCLUSIONS: Endometriosis of the bladder is extremely rare and usually presents as urinary problems and rarely as acute abdomen.

[Exophthalmos caused by orbital metastasis of prostatic carcinoma]. / Exoftalmos por metástasis orbitaria de carcinoma prostático.

A case of orbital metastasis from Whitmore stage D adenocarcinoma of the prostate is described. Clinically, it presented as rapidly progressing exophthalmos of the right eye with elevation (ptosis) and abduction paralysis. The associated clinical picture of a one-year history of prostatism prompted patient referral to our department. When a patient presents with an orbital tumor and a history of cancer localized to another site, the metastatic origin of the condition should be suspected and metastasis to other sites sought. A negative finding warrants performing orbital biopsy to confirm the diagnosis. Although excision of single metastatic tumors in this site has been described, coexisting metastasis to bone and lymph nodes, the hormone dependence that these present and prostatic cancer contraindicate resection of the orbital metastatic tumor. Following bilateral orchiectomy and hormone therapy with antiandrogens micturitional symptomatology improved, tumor size was reduced, and exophthalmos disappeared. The case described herein is not the first case of this type of metastatic lesion reported in the literature; 28 cases have been reported to date. This uncommon clinical presentation with extraurological manifestations gives us an idea of the broad clinical spectrum the biological behaviour of this tumor type can adopt.

[Partial parietal cystectomy and cystoplasty with a lyophilized human dura mater patch as and alternative in palliative oncological bladder surgery]. / Cistectomía parcial parietal y cistoplastia con parche de duramadre humana liofilizada como alternativa en cirugía oncológica vesical paliativa.

Fifteen patients with infiltrating bladder carcinoma underwent partial cystectomy and cystoplasty with lyophilized human dura at our hospital from 1983 to 1988. The 5-year survival rate was 75% for stage B1, 60% for B2, 40% for C and 0% for D1. There were no intra- or post-operative deaths and the post-operative complications were few. This procedure may be useful in selected patients with bladder tumors who cannot be submitted to more radical procedures due to a coexisting pathological condition representing a high surgical risk or in elderly patients.
