1/199. Surgically created fourth-third cranial nerve communication: temporary success in a child with bilateral third nerve hamartomas. Case report.

    Shortly after birth, an otherwise healthy infant developed eye deviation and ptosis due to a hamartomatous lesion of the interpeduncular segment of the right oculomotor nerve. The left nerve became similarly involved when the child was 1.5 years of age. Direct nerve repair was not possible. Instead, the trochlear nerve was divided and its proximal end was attached to the distal end of the third nerve. Elevation of the upper eyelid and partial adduction of the eye developed gradually over the ensuing 3 to 5 months. Both functions were lost after an additional 2 months, presumably as a result of tumor recurrence or neuroma formation. This case report shows that surgically created fourth-third cranial nerve communication is feasible and may merit consideration under similar circumstances.

2/199. Spontaneous rupture of splenic hamartoma: a case report.

    Splenic hamartomas are rare. The authors report a case of spontaneously ruptured splenic hamartoma in a 5-month-old boy. This rupture led to the death of the child. If abdominal pain is present and a mass is palpated, the splenic hamartoma should be managed surgically in an expeditious manner. There have been only two known previous reports of spontaneous rupture of splenic hamartoma in adults, but none in children.

3/199. spinal cord hamartoma: case report.

    OBJECTIVE AND IMPORTANCE: spinal cord hamartomas are infrequently mentioned in the literature. The authors present a unique report detailing the clinical presentation of a spinal cord hamartoma, with supporting radiographic and pathological data. CLINICAL PRESENTATION: A 26-year-old man presented with progressive right upper extremity weakness. Imaging studies revealed an exophytic cervical spinal cord mass. INTERVENTION: Open biopsy was undertaken and revealed tethering of the lesion to the dura. A pathological examination revealed a spinal cord hamartoma. CONCLUSION: The patient's symptoms improved postoperatively, suggesting that tethering of the spinal cord was responsible for the symptoms. Although unusual, hamartoma should be included in the differential diagnosis of an exophytic spinal cord lesion.

4/199. Chondroid hamartoma presenting as a neonatal nasal mass.

    We present a case of a 3-month-old female with a right nasal mass. Upon evaluation with computed tomography, magnetic resonance imaging and angiography, a large right intranasal mass extending through the cribiform plate, displacing the dura, was noted. The patient underwent a combined midfacial degloving and bifrontal craniotomy for complete resection of the tumor mass. Pathologic evaluation demonstrated a mesenchymal tumor with spindle and stellate cells from which islands of immature cartilage emerged. The spectrum of histologic features closely resembled a mesenchymal chondroid hamartoma typically located in the chest wall. It is the first reported case of a chondroid hamartoma of the head and neck in the literature to date. We examine the characteristics and treatment of this unusual tumor.

5/199. Brunner's gland hamartomas: report of three cases.

    Brunner's gland hamartoma is a rare duodenal tumor, which grew larger than 2 cm in diameter in a very limited number of cases. Since the first description in a patient with fatal duodenal intussusception by Cruveilhier in 1835, approximately 143 cases have been reported in the English literature, and only 25 cases had tumor growth to more than 2 cm in diameter. To the best of our knowledge, only 4 cases have been reported in taiwan. We present three of Brunner's gland hamartomas. In one patient the tumor was located on the secondary portion of the duodenum, which presented with massive tumor bleeding and measured 3.0 cm in diameter. The other two were both located on the duodenal bulb, which presented with abdominal pain and measured 2.0 and 1.3 cm in diameter, respectively. One of the patients received endoscopic ultrasonography which showed specific findings. Two patients received laparotomy and tumor excision; the other one received endoscopic polypectomy. All 3 patients recovered well without any complications.

6/199. A case of familial angiolipomatosis with Lisch nodules.

    Familial angiolipomatosis is a rare syndrome that may be confused clinically with neurofibromatosis type 1. This condition is most often inherited in an autosomal recessive manner; however, several reports have been published suggesting an autosomal dominant mode of inheritance. Angiolipomatosis, although somewhat disfiguring, is a benign condition with no known association with malignant neoplasms. This is in contradistinction to neurofibromatosis, an autosomal dominant syndrome associated with a myriad of benign and malignant neoplasms. It is, therefore, important to discriminate this entity from neurofibromatosis when a patient presents with multiple subcutaneous tumors and a family history of similar lesions. Described is a case of a prison inmate with a history of seizures and "neurofibromatosis" without clinical documentation. Lisch nodules were noted on the irides. Postmortem examination showed multiple subcutaneous yellow tumors on the chest and arms. Fine-needle aspiration of 1 mass yielded adipose tissue with prominent vessels; histologic sections of another mass showed angiolipoma. The remainder of the autopsy showed significant coronary artery disease and a remote cerebral infarction of the temporal lobe but no signs of neurofibromatosis. We feel that the presence of multiple angiolipomas in combination with Lisch nodules lends credence to the proposed relationship between fatty tumors and neurofibromatosis suggested by other authors.

7/199. Congenital smooth muscle hamartoma of the conjunctival fornix.

    PURPOSE: Congenital smooth muscle hamartomas are benign tumors composed of proliferating smooth muscle cells. They are usually seen as abnormal patches of skin. Ocular involvement of congenital smooth muscle hamartomas is unusual, with rare reports of patients with external eyelid involvement or proptosis resulting from orbital tumors. We describe a patient with a congenital smooth muscle hamartoma that involved the tarsal conjunctival fornix. methods: review of the patient's medical records, including the results of ophthalmologic, radiologic, and histologic examinations. RESULTS: A healthy 2-year-old boy was initially seen with a conjunctival mass. He had a discrete, gray, cystic-appearing lesion in the inferior fornix of the left eye. A magnetic resonance imaging study revealed no signs of extension of the lesion into the orbit. The lesion was surgically excised. Histologic sections showed large bundles of smooth muscle with a fibrotic background and interdigitating fat, consistent with a diagnosis of a congenital smooth muscle hamartoma. CONCLUSION: To our knowledge, this is the first report of a patient with a congenital smooth muscle hamartoma arising from the conjunctival fornix. It presumably originated from either the smooth muscle of the vascular endothelium or from the capsulopapebral muscle. Congenital smooth muscle hamartoma should be considered in the differential diagnosis of cystic-appearing conjunctival fornix lesions.

8/199. Fine-needle aspiration cytology of mesenchymal hamartoma of the chest wall.

    We report on an uncommon entity, the so-called "chest wall chondromatous hamartoma" or "mesenchymal hamartoma of the chest wall" (MHCW), diagnosed by fine-needle aspiration (FNA) cytology in a 6-mo-old boy. Radiologic features were those of an aggressive lesion with rib expansion and destruction, that contrasted with aspirate smears showing bland cartilage and spindled mesenchymal elements. The clinicoradiographic features together with the FNA yield of mixed cellular elements aided in the correct diagnosis of MHCW.

9/199. Pulmonary hamartoma. A rare case report.

    Pulmonary hamartoma is a rare lung neoformation, usually symptomless and by chance discovered, of a probable dysontogenetic origin with prevailing cartilaginous tissue and adult, onset age. The Authors report a rare case of a 25-year-old student, symptomless and fortuitously found by means of a radiograph of the chest. Many interesting features characterize the case report: histological nature of the pulmonary hamartoma, mainly vascular, so much as to feign an angiosarcoma at the macroscopical examination, and with small peripheral calcifications as shown by lung CT scan; the measures (about 7 cm) plentifully above the parameters usually reported in the literature (from 2 cm to 4 cm); the young onset age (about 10 years old). We may consider a case exceptionally reported in the literature. Besides, on the base of a few studies and of our experience, the results of the pulmonary hamartoma growth rate and doubling time are reported.

10/199. Cartilaginous hamartoma of the chest wall with secondary aneurysmal cyst-like areas in an infant: a case report.

    A case of a four-month-old infant diagnosed as cartilaginous hamartoma of the rib is presented. This rare tumor usually presents at birth. The patient had respiratory distress syndrome. Swelling of the ribs was palpable on physical examination and the infant underwent surgery for excision of the ribs. Histopathologically, the tumor showed benign focal overgrowth of normal skeletal elements with cartilaginous, vascular and primitive-appearing mesenchymal elements. Additionally, secondary aneurysmal cyst formation coexisted with the tumor. The diagnosis was infantile cartilaginous hamartoma of the rib. In this entity, primitive-appearing mesenchymal stroma may be mistaken for a malignant condition. Usually a benign clinical course is expected and treatment is by block excision.
