1/619. Bone involvement in a case of Kaposi sarcoma.

    BACKGROUND: Extracutaneous involvement is rare in the classical form of Kaposi sarcoma (KS). observation: We report a case of bone involvement revealed by bone pain. Magnetic resonance (MR) images demonstrated the local invasion of bone from cutaneous lesions. Bone biopsy confirmed bone involvement. The patient was treated with vindesine. Bone pain progressively disappeared. CONCLUSION: Bone involvement has rarely been reported in classical KS though 4.5% of the patients were affected when it was systematically sought. Treatment of symptomatic lesions requires radiotherapy or chemotherapy.

2/619. E.N.T. manifestations of Von Recklinghausen's disease.

    Von Recklinghausen's disease (VRD) is a neurocutaneous, systemic disease characterized by CNS tumors and disorders, cafe-au-lait spots, generalized cutaneous neurofibromata, skeletal deformities, and somatic and endocrine abnormalities. It is an autosomal dominant, hereditary disorder found in approximately 1:2500 to 3300 births. There are many manifestations of this disease in the head and neck region of interest to the otolaryngologist. case reports of three patients with multiple ENT involvements are detailed. A review of the literature is presented with a brief discussion of diagnosis and treatment. The most common intracranial tumor in the adult is the acoustic neuroma, usually bilateral, while in the child it is the astrocytoma. A defect in the sphenoid bone is common and may produce temporal lobe herniation into the orbit causing pulsatile exophthalmos. Involvement of the facial bones usually causes radiolucent defects secondary to neurofibromata within nerve pathways, and a variety of asymmetrical changes, especially within the mandible. "elephantiasis" of the face is a hypertrophy of the soft tissues overlying a neurofibroma, often quite extensive and disfiguring. Laryngeal and neck involvement may compromise the airway and early and repeated surgical intervention is required. The over-all malignancy rate approaches 30%, indicating that the patient with VRD may be predisposed to developing a malignancy. There appears to be an increased surgical risk in these patients, with some demonstrating abnormal responses to neuromuscular blockade.

3/619. Hemophiliacs bone pseudotumors.

    Four cases of proved hemophiliac pseudotumors caused by intraosseous bleeding are reported. Five lesions were found at the uncommon locations involving the cranial vault, mandible, phalanx, distal femur and distal tibia. The conventional radiographic and computed tomographic findings are expansile osteolytic destruction, cortical thinning, partial breaking cortex or pathological fracture, and sometimes associated soft tissue mass. Ultrasonographic feature of one case at the phalanx shows cortical expansion and thinning contained mixed echogenicity in the medullary canal with soft tissue extension. T99m DTPA of one case at the distal femur shows increased vascular flow and uptake at right distal tibia and left distal femur.

4/619. adult onset of multifocal eosinophilic granuloma of bone: a long-term follow-up with evaluation of various treatment options and spontaneous healing.

    We report a case of multifocal-monosystemic Langerhans cell histiocytosis (LCH), formerly usually referred to as eosinophilic granuloma (EG) of bone. The condition developed in a 36-year-old man. A notable infrequent thoracic spine location and two successive distinct costal lesions were observed. Both the first costal site and the vertebral location healed spontaneously; the second costal lesion underwent biopsy resection. The patient's disease course with an 8-year follow-up is discussed with reference to various treatment options, emphasising in selected cases a watchful conservative approach, in view of the widely documented potential for spontaneous healing.

5/619. Single bone involvement in congenital syphilis.

    A case of congenital lues with single bone involvement is reported. Such a presentation of this disease can cause problems in diagnosis. This aspect of the case is discussed and the literature on the subject reviewed. The uniqueness of this case is emphasized for only two other such cases have been reported in the literature.

6/619. The aetiology of congenital angulation of tubular bones with constriction of the medullary canal, and its relationship to congenital pseudarthrosis.

    It is suggested that there is a group of cases of congenital angulation of tubular bones in which the lesion is a defect of ossification of the primary cartilaginous anlage and in which neurofibromatosis is not implicated. It appears that in this group the prognosis with regard to the resolution of deformity and the prevention of pseudarthrosis with conservative treatment or relatively simple surgical procedures is better than that in the neurofibromatous type.

7/619. A surgical method for treating anterior skull base injuries.

    skull base surgery was performed on 18 patients with anterior skull base injuries. The operative technique consisted of opening the operative field in the anterior skull base via a coronal incision and a frontal craniotomy, debridement of the anterior skull base including the injured dura mater, performing drainage from the anterior skull base to the nasal cavity by ethmoidectomy, and reconstructing the resulting dural and anterior skull base defect using bilateral temporal musculo-pericranial flaps and a bone graft. Seventeen of the 18 patients recovered without any complications, although epidural abscesses in the anterior skull base had been present in four patients at the time of the operation. Only one patient developed an epidural abscess in the anterior skull base after the operation. None of the patients developed any other complications including meningitis, recurrent liquorrhoea or cerebral herniation. Satisfactory aesthetic results were achieved in 16 of the 18 patients. In one patient, uneven deformity of the forehead, which was caused by the partial sequestration of the frontal bone due to postoperative infection, was observed. In another patient, a depressed deformity of the forehead, which was caused by the partial loss of the frontalis muscle following the use of the frontal musculo-pericranial flap instead of a temporal musculo-pericranial flap, was observed. Anterior skull base reconstruction using bilateral temporal musculo-pericranial flaps provides excellent results in terms of patient recovery and aesthetics.

8/619. Elongated stylohyoid process: a report of three cases.

    The stylohyoid process is part of the stylohyoid chain--the styloid process, the stylohyoid ligament, and the lesser cornu of the hyoid bone. The stylohyoid chain is derived from the second branchial arch. Mineralisation of the stylohyoid ligament and ossification at the tip may increase the length of the styloid process. An elongated stylohyoid or styloid process is considered to be the source of craniofacial and cervical pain commonly known as Eagle's syndrome. In some instances the stylohyoid process may be considerably elongated, yet remain asymptomatic. This paper reports three patients with elongated stylohyoid processes discovered incidentally on routine radiographic examination.

9/619. Identification of calcium oxalate deposits in bone by electron diffraction.

    Oxalosis involving bone secondary to prolonged chronic renal failure and long-term dialysis occurred in a living patient. The cystalline deposit in the small fragment of bone was identified by electron diffraction.

10/619. A case report on aggressive fibromatosis with bone involvement.

    Aggressive fibromatosis is a locally infiltrative fibroblastic tumour that arises from fascial planes of soft tissue but does not metastasize. It is known to invade muscle, subcutaneous tissue and neurovascular structures. However, bone involvement is very rare and there has been few reports of bone involvement. We present a case of a young man with aggressive fibromatosis of the right lower leg with fibula involvement.
