ABSTRACT

Adenoid cystic carcinomas, the most common malignancies of the lacrimal gland, are rare overall. We describe a patient who presented with right periorbital swelling developing over 5 months and magnetic resonance imaging findings of a soft tissue mass in the lacrimal fossa with invasion of the adjacent bone. The patient underwent right lateral orbitotomy with tumor debulking. Pathologic analysis showed neoplastic cells in a predominantly cribriform pattern, and the patient was diagnosed with an adenoid cystic carcinoma of the lacrimal gland. We review the clinical, radiographic, and histopathologic features of these rare, aggressive malignancies as well as treatment options with reference to the current literature.

ABSTRACT

PURPOSE: As peritoneal dialysis (PD) is the preferred long-term dialysis modality in the pediatric population, we sought to identify risk factors for mortality and reoperation. METHODS: A retrospective review of patients undergoing PD catheter insertions at a single center from 1994-2009 was performed. The following variables were evaluated: age (<1 year), comorbidities, omentectomy, concomitant gastrostomy, and laparoscopic technique. Multivariable Cox regressions analyses were used to evaluate patient survival and reoperation-free survival of PD catheters. RESULTS: 207 patients with a median age of 10 years underwent PD insertion. Mortality was 7% with a median follow up of 72 months. Reoperation for malfunction and infection was required in 49% of patients with a median PD catheter survival of 11 months. Reoperation for hernias occurred in 14% of patients. Multivariate Cox regressions analyses identified age <1 year, lack of omentectomy, concomitant gastrostomy, and prematurity as variables significantly associated with higher rates of mortality or reoperation. CONCLUSIONS: In this large study of pediatric patients undergoing PD, higher complication rates were noted in infants less than one year of age. Concomitant gastrostomy was associated with a higher rate of reoperation for infection. Failure to perform omentectomy was associated with a higher rate of catheter failure.
