We report a new case of spermatic cord lymphangioma in a infant 2 years old. The initial diagnosis was funicular hydrocele. The treatment was the local excision of tumor and the diagnostic was histological. Postoperative course was excellent. Must be explored the transillumination of the mass which would have led us to think other the diagnosis different from that of the cord hydrocele before the operation since it would have given negative. During the operation, must the assured that the cystic anomaly is limited to spermatic cord, to evite recurrences in the postoperative course. 相似文献

Contribution of a retrospective series of 16 patients with type II absorptive hypercalciuria over a total of 1.041 patients undergoing metabolic study due to relapsing renal lithiasis. Clinical history of lithiasis, biochemistry prior to treatment and instituted therapy were examined in all cases. Stones composition, radiologic appearance of lithiasis and evolution of biochemical parameters after medical treatment with a mixture of phosphates were also studied. 相似文献

The schwannoma is a tumor resulting from the Schwann cells of neural shwath, being its retroperitoneal localization quite unusual. This tumor is clinically unspecified and in most of the cases it originates symptoms coming from the compression of the close structures when its localization is retroperitoneal. Its diagnosis is quite often fortuitous being confirmed by anatomopathological study afterwards. The treatment is surgical radical exeresis with subsequent followup. We report a new case of this uncommon retroperitoneal pathology in a female patient showing a nonspecific clinic. Two years after the surgery she remains asymptomatic without any radiological evidence of recidive. 相似文献

Primary melanoma of the urinary bladder is a rare neoplasm to which very strict diagnostic criteria apply. Although reports of previous cases exist, these criteria have yet to be met. We report a case of a young lady from whom a malignant melanoma of the bladder was resected. This was presumed to be primary as detailed investigation failed to find any other site from which metastases could have originated. We discuss the diagnostic criteria of this entity and stress the difficulty in conclusively demonstrating that, despite some of these criteria being met, a lesion such as this is primary in origin. This case could be the longest surviving patient with primary melanoma of the bladder, however we will never be able to prove that spontaneous regression of an undiagnosed extravesical primary malignant melanoma did not occur. 相似文献

Inverted papilloma is a rare tumour (2.2% of urothelial tumours) considered to be benign. The bladder is the most frequent site and growth tends to be endophytic towards the submucosa. Haematuria and obstruction symptoms appear to be the most typical clinical manifestations. Contribution of two cases of inverted bladder papilloma; one showing very unusual clinical development with relapsing acute urinary obstruction. Strict follow-up is recommended in spite of its benign behaviour as it may become associated to transitional cell carcinoma. Literature review on this tumoral entity in terms of etiology, clinical manifestations, diagnosis and treatment. 相似文献

Recurrent gastroesophageal reflux following fundoplication is a challenging problem, because it is usually refractory to medical treatment and a second, technically difficult, antireflux operation is required. Different factors that may contribute to surgery failure have been identified in children. We present 8 cases who underwent redofundoplication after failed procedures, from a total number of 96 patients operated on due to gastroesophageal reflux. Four patient's had their initial fundoplication performed at our institution. Six patients were neurologically impaired, six had chronic pulmonary disease, and two had esophageal atresia. The main presenting symptoms were recurrent vomiting (n = 8) and aspiration (n = 4). Gastroesophageal reflux was confirmed by barium swallow and endoscopy. Operative findings showed wrap breakdown in two cases, warp breakdown associated with hiatal hernia in five, wrap breakdown associated with paraesophageal hernia in two cases, and paraesophageal hernia with normal wrap in one. A second Nissen procedure were performed in five cases, whereas a Collis-Nissen gastroplasty was realized in three with a short esophagus. Six patients had a successful outcome remaining symptom free, one has severe disphagia, and one has recurrent vomiting. In our experience, patients with recurrent gastroesophageal reflux disease should undergo an antireflux procedure tailored to specific anatomic or functional abnormalities. 相似文献

We present 2-year-old patient with a allopecia lesions in scalp, and clinique diagnostic of Cutis Aplasia. The anatomopathologic study have diagnosed the lesions as Acquired Progressive Lymphangioma (APL). Is a rare vascular tumour that has a tendency to appear in childhood an to progress slowly over the years. It could present as a solitary erythematous macule or plaque and a simple excision is usually curative. Our patient is the youngest reported in the literature. 相似文献
