Giant umbilical cord in a normal preterm infant: a case report and review of the literature.

BACKGROUND: Giant umbilical cord, defined as a cord diameter of more than 5 cm, is an extremely rare malformation. There are few case reports of giant umbilical cord often associated with patent urachus duct or cystic malformation. These cases are usually managed by surgical excision and repair of patent urachus or cyst resection. CASE PRESENTATION: We report the case of a 1-day-old Iranian boy with giant umbilical cord detected postnatally. The pregnancy course was uneventful, except for preterm premature rupture of the membrane and preterm delivery. There was no relevant family history. The patient was delivered by vaginal delivery with a good Apgar score. On clinical examination, the umbilical cord was very thick (about 6 cm in diameter), and huge fluctuating Wharton's jelly was observed. Other organs were normal. During the hospital stay, the patient did not develop any complications except borderline hyperbilirubinemia, which improved with conventional phototherapy. Since the umbilical cord had no discharge and was dried, the newborn was discharged with advice for cord drying care. CONCLUSION: The newborn was well, and the dried umbilical stump was detached after 32 days, leaving a granulomatous structure without discharge. The patient was followed up for 4.5 months and had no problems except delayed separation of the umbilical cord.

[Nonsurgical and surgical treatment of an urachal fistula in an alpaca cria. A case report]. / Konservative und chirurgische Therapie der Urachusfistel bei einem Alpaka-Cria. Ein Fallbericht.

Urachal fistula is a neonatal condition. There are two reported forms: a congenital and an acquired form. We describe the case of a 6-hour-old female alpaca cria that was presented with a damp umbilicus and a meconium impaction. Conservative treatment of the urachal fistula with local and systemic medication was unsuccessful after 6 days; therefore, a resection of the umbilicus under general anaesthesia was performed. Reconvalescence was uneventful.

Multimodality management of urachal carcinoma: the M. D. Anderson Cancer Center experience.

PURPOSE: Enteric type adenocarcinomas arising in the dome of the bladder or along the urachal ligament are uncommon. To improve our understanding of urachal carcinoma and define outcome with current management, we performed a retrospective review of cases seen at the M. D. Anderson Cancer Center. MATERIALS AND METHODS: We reviewed the records of 42 patients with urachal carcinoma evaluated at our institution from 1985 to 2001. Specifically, we sought to evaluate the importance of extent of disease, surgical characteristics and systemic therapy on clinical outcome. RESULTS: Of the 42 patients 7 had clinically evident metastases at diagnosis and 35 had resectable disease that was managed initially with surgery. Overall survival from diagnosis for all 42 patients was 46 months with 40% surviving at 5 years. Of the resected cases 16 (46%) remain disease-free (median followup 31 months). Covariates associated with long-term survival were negative surgical margins (p = 0.004) and absence of nodal involvement (p = 0.01). Median survival from recognition of metastatic disease was 24 months in 26 patients in whom metastases ultimately developed. Chemotherapy for metastatic disease produced only 4 significant responses, including 3 of 9 patients treated with 5-fluorouracil and cisplatin containing regimens. CONCLUSIONS: Urachal carcinomas are usually locally advanced at presentation with a high risk of distant metastases. However, long-term survival following radical resection occurs in a significant fraction of patients (16 of 35 in our series), supporting an attempt at margin-negative, en bloc resection if at all possible. Chemotherapy appropriate for enteric type adenocarcinoma can induce objective responses but meaningful improvement in survival is not yet demonstrated.

Adenocarcinoma of the urachus associated with elevated levels of CA 125.

Adenocarcinoma of the urachus is a rare genitourinary tumor with a poor prognosis. The treatment of choice is en bloc surgical resection, although combination therapy with surgery and chemotherapy has been used with mixed results. We describe a 69-year-old woman with adenocarcinoma of the urachus and elevated serum levels of CA 125 tumor marker. She was treated with resection plus 5-fluorouracil, doxorubicin and mitomycin, alternating with platinum-based chemotherapy. The serum CA 125 level decreased precipitously after the operation and became normal after 2 months of chemotherapy. The patient remained free of disease 1 year postoperatively. Serum CA 125 may be a useful tumor marker for urachal carcinoma and adjuvant chemotherapy may be effective in treating the disease.
