1/543. Novel TSC2 mutation in a patient with pulmonary tuberous sclerosis: lack of loss of heterozygosity in a lung cyst.

    A Japanese patient with tuberous sclerosis (TSC), who manifested with multiple lung cysts and pneumothorax, is described. All exons of two TSC genes, TSC1 and TSC2, in peripheral blood leukocytes from the patient were analyzed by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). A novel T-to-G transition was found in exon 19 of TSC2 at nucleotide position 2168. This mutation caused an amino acid change, L717R. There was no such mutation in any other family members or in 100 normal Japanese. An automated sequencer-assisted quantitative analysis of normal and mutated SSCP-bands revealed no loss of heterozygosity (LOH) in the lung cyst tissue of the patient.

2/543. Lymphoepithelial cyst with crystalloid formation. Cytologic features of two cases.

    BACKGROUND: The presence of amylase crystalloids (AC) in cystic lesions of the parotid gland is a rare occurrence and has been diagnosed to date as sialadenitis. We report the first two cases of parotid lymphoepithelial cyst (LC) containing this type of crystalloid. CASES: Case 1, a 56-year-old male, presented with a 3-cm parotid cyst. Fine needle aspiration (FNA) was performed on the mass. Smears showed numerous crystalloids identical to those described as crystallized amylase. Case 2, a 36-year-old female, had a 2-cm parotid mass. FNA smears exhibited the same features as did case 1. The two patients were treated with superficial parotidectomy, and an LC containing AC was diagnosed in both cases. CONCLUSION: When the above findings are present on FNA of parotid gland, the diagnosis of LC must be considered.

3/543. Inflammatory cysts of the pelvic peritoneum.

    Three young women with abdominal distension due to pelvic masses were investigated using ultrasound and conventional radiographic techniques. While the latter revealed masses of soft tissue density arising from the pelvis and displacing bowel, the sonogram indicated the morphologic features of thin-walled multiloculated cysts. They were located entirely within the peritoneal cavity and contained serous to serosanguineous fluid. The mesholelial lined walls were infiltrated with chronic inflammatory cells and were adherent to chronically inflamed fallopian tubes. Although these acquired cysts are familiar to pathologists and gynecologists, the literature contains little information about them.

4/543. pancreatitis caused by duodenal duplication.

    The authors present the investigations and surgical treatment of two cases of duodenal cystic duplication. abdominal pain and gastroesophageal reflux were the most important symptoms and signs associated with an history of recurrent acute pancreatitis. Computed tomography scan, ultrasound examination, and cholangiography confirmed preoperatively the diagnosis, and a transduodenal surgical approach was carried out in both children. A simple marsupialization of the cyst was performed in the former, and a sphincterotomy with papillosphincteroplasty was associated in the latter. The diagnosis was confirmed by microscopy, and both the children are asymptomatic after a 14 and 18 months of follow-up. This report focuses on the importance of the cholangiopancreatography for every child presenting with recurrent, unexplained bouts of acute pancreatitis, and underlines the technical surgical aspects on the basis of the anatomic identification of the malformation.

5/543. The Chiari II malformation: lesions discovered within the fourth ventricle.

    Structural lesions associated with the Chiari II malformation have been identified within the fourth ventricle in 8 patients. During the 42-month period encompassing the operations of the 7 patients treated surgically, only 9 other patients were explored without the discovery of some associated structural lesion. The patients ranged in age from 2 to 26 years. The following lesions were identified: glial or arachnoidal cysts (3 patients), glial or choroidal nodules (3 patients) and subependymoma (2 patients). These lesions were all situated in the roof of the fourth ventricle adjacent to or interspersed with the choroid plexus. Only the cystic lesions were identified by preoperative imaging. In only 1 case did the associated lesion, a 2-cm cyst, seem to contribute to the patient's clinical presentation. Structural lesions of the fourth ventricle associated with the Chiari II malformation are common in patients who are submitted to decompression. These lesions may be dysplasias of developmental origin, or they may be reactive lesions related to chronic compression and ischemia. They do not necessarily required biopsy or excision.

6/543. Interpseudophakos Elschnig pearls associated with late hyperopic shift: a complication of piggyback posterior chamber intraocular lens implantation.

    We report 3 cases of bilateral piggyback lens implantation in which late hyperopic shift occurred associated with Elschnig pearl formation in the peripheral interface between the 2 lenses.

7/543. Symptomatic cervical macrocyst as a late complication of subtotal hysterectomy. A case report.

    BACKGROUND: Ablation of the endocervical canal is sometimes performed as an adjunct to subtotal hysterectomy in an attempt to reduce mucous discharge and the risk of future neoplasia. Cystic accumulations within the canal of a partially obliterated cervical stump have not previously been reported to follow this practice. CASE REPORT: A 41-year-old woman presented with subacute cramping and cystic enlargement of the cervical stump on clinical, sonographic and magnetic resonance evaluation four years subsequent to a subtotal hysterectomy performed for menorrhagia. Cervical biopsies and cytology were benign, and vaginal trachelectomy was performed. pathology demonstrated the fluid pocket to be a very large retention cyst (nabothian) that had occupied and distended the partially obliterated endocervical canal. CONCLUSION: Ablation of the cervical canal at subtotal hysterectomy may result in symptomatic entrapment of nabothian cysts. Internalization of the transformation zone and partial obliteration of the canal are postulated as predisposing factors.

8/543. Evaluation and management of benign, non-congenital tongue masses in children.

    Lingual tumors are rare, primarily benign, lesions in the pediatric population. Congenital lesions, such as hemangiomas, lymphatic malformations, dermoids, hamartomas and thyroglossal ducts cysts, are seen more commonly. Primary, non-congenital lingual neoplasms are less common in children. We present three patients with benign lingual neoplasms. Evaluation, management, pathology and follow-up are discussed.

9/543. Expanding septum pellucidum cyst due to a traumatic ventriculoperitoneal shunt.

    A rare complication of a ventriculoperitoneal (VP) shunt is reported. Serial imaging studies demonstrated the formation of an expanding septum pellucidum cyst after an indwelling shunt tube penetrated the wall of the septum pellucidum. This complication should be borne in mind if patients have symptoms of intermittent obstructive hydrocephalus or related to pressure effects from the septum pellucidum after VP shunting.

10/543. A rare case of completely isolated duplication cyst of the alimentary tract.

    A rare case of a gastrointestinal cystic duplication in a 7-day-old infant is described. The duplication diagnosed antenataly at 25 weeks of gestation was found during surgery to be separated from the gastrointestinal tract, hanging on a vascular pedicle, with no connection to the mesentery. The duplication was excised, and postoperative follow-up of 14 months was uneventful. The possible pathogenesis of this malformation is discussed.
