11/254. aorta-cutaneous fistula as a rare complication of localized chronic mediastinitis.

    A 35-year-old man was admitted 5 years after congenital heart surgery complicated by staphylococcus aureus and a cutaneous fistula located at the left fourth intercostal space. He was febrile (40 degrees C), suffering from sternal pain and suppuration from the old fistula. During examination arterial blood suddenly discharged from the fistula, so that surgery was immediately instituted. An infected Dacron tube implanting on the ascending aorta for a central aorto-pulmonary shunt was at the origin of a false aneurysm: this had led to the repeat formation of an aorta-cutaneous fistula and outbreak of external bleeding.

12/254. clofazimine-induced crystal-storing histiocytosis producing chronic abdominal pain in a leprosy patient.

    clofazimine-induced crystal-storing histiocytosis is a rare but well-recognized condition in the literature. Besides the common reddish discoloration of the skin, clofazimine produces gastrointestinal disturbances-sometimes severe abdominal pain, prompting exploratory laparotomy, because pathologic and radiologic findings can produce diagnostic difficulties if the pathologic changes caused by clofazimine are not recognized. The authors report such a case in a leprosy patient to emphasize the importance of history taking, the radiologic abnormalities of the small intestine, and the pathologic findings in small intestine and lymph node biopsies. clofazimine crystals are red in the frozen section and exhibit bright-red birefringence. However, they are clear in routinely processed histologic sections because they dissolve in alcohol and organic solvents. They also appear as clear crystal spaces during electron microscopic study, but some osmiophilic bodies can be observed. histiocytosis caused by clofazimine crystals produces infiltrative lesions in radiologic studies mimicking malignant lymphoma or other infiltrative disorders. Associated plasmacytosis in the histologic sections can simulate lymphoplasmacytic lymphoma or multiple myeloma with crystal-storing histiocytosis. With the knowledge of this rare condition caused by clofazimine, appropriate management to avoid an unnecessary laparotomy is possible.

13/254. Chronic subdural haematoma presenting with transient ischaemic attacks--a case report.

    We report a middle-aged man who presented with repeated episodes of transient ischaemic attacks (TIA) in the setting of a chronic subdural haematoma. This case report discusses the various pathophysiologic mechanisms whereby such TIA may occur in chronic subdural haematoma. We also highlight the importance of cranial imaging in cases of TIA.

14/254. Macroscopic and microscopic mucinosis in chronic sclerodermoid graft-versus-host disease.

    Secondary cutaneous mucinosis is a well-recognized feature of connective tissue diseases such as lupus erythematosus and dermatomyositis. We report the first three cases of dermal mucinosis in association with severe chronic cutaneous graft-versus-host disease of the sclerodermoid variety. One patient had clinical changes due to abundant mucin accumulation within the papillary dermis (mucinoma). In the other two patients histological examination revealed extensive deposits of mucin predominantly within the reticular dermis. The microscopic appearances were striking, with numerous vacuolated spaces interspersed between collagen bundles. We speculate that this appearance is the result of ground substance becoming trapped within grossly sclerodermoid connective tissue.

15/254. Salivary gland choristoma of the middle ear: a case report.

    A choristoma is a nonneoplastic proliferation of histologically normal tissue that forms at an abnormal site. It is extremely uncommon in the middle ear space. It appears to be a developmental abnormality and may be associated with abnormalities of adjacent structures. It usually occurs with unilateral conductive hearing loss and requires a differential diagnosis from other mass lesions in the middle ear cavity. This article discusses a case of salivary gland choristoma of the middle ear that we believe to be the 24th case reported on this subject.

16/254. trichomonas vaginalis in a perinephric abscess. A case report.

    A patient with chronic vulvo-vaginitis due to trichomonas vaginalis, and obstructive uropathy associated with renal calculi, developed a perinephric abscess following trauma incurred in a motorcycle accident. T. vaginalis was seen on smear and cultured from the purulent drainage from the perinephric abscess. Although T. vaginalis is commonly pathogenic only to the lower genito-urinary system, the upper urinary tract may very rarely be involved by ascending infection. If this protozoan spreads to extraluminal sites the inflammatory potential is marked, as has been found in animals with experimental infection. Examination of a fresh smear of pus may be critically important in the diagnosis of closed-space infections of unknown etiology.

17/254. Spontaneous resolution of chronic subdural hematoma.

    BACKGROUND: Spontaneous resolution of chronic subdural hematoma has rarely been reported in the literature, and its mechanism has not been fully investigated. Response to surgery has been very satisfactory; in fact, this is generally considered the treatment of choice. methods: From a series of 24 cases of chronic subdural hematomas, we observed five patients between 1996 to 1998. These patients showed headache and decrease of cognitive level, 4-5 weeks after minor head injury. Neurologic evaluation revealed only worsening of mental function according to Mini Mental State Examination (MMSE). Computed tomography (CT) scans showed brain atrophy and chronic subdural hematoma without increased intracranial pressure. These patients were treated by clinical observation and serial cerebral CT scans. RESULTS: After 7 to 10 days, all patients showed improvement of clinical signs. After 30 to 45 days, radiological disappearance or marked reduction in size of the hematoma and complete clinical recovery were obtained. No neurological deficits and no recurrences have been observed during follow-up (3 months to 2 years). CONCLUSIONS: We believe that age greater than 70 years, decreased cognitive level (MMSE = 21), brain atrophy, and absence of increase of intracranial pressure are clinical and radiological signs that allow one to choose conservative treatment.

18/254. Subconjunctival cysts following silicone oil injection: a clinicopathological study of five cases.

    PURPOSE: To study the occurrence, risk factors and management of subconjunctival cysts formed following the use of intraocular silicone oil as a tamponade. methods: We analyzed 5 cases of single and multioculated subconjunctival oil cysts between 1986 and 1996. RESULTS: cysts were observed 15 days to 4 months following silicone oil injection. Clinically they showed minimal inflammatory signs but histopathology of removed cysts showed emulsified silicone oil globules with chronic inflammatory cellular infiltration. CONCLUSION: Though silicone oil is considered to be nontoxic, it can cause chronic inflammation when spilled into the subconjunctival space.

19/254. Arthrodiatasis for chondrolysis with hinge abduction: a case report.

    A 13-year-old boy with bilateral chronic slipped capital femoral epiphysis was referred to the Nagoya University Hospital. Chondrolysis occurred on the left side 3 months after a subcapital wedge osteotomy and a concavity of the femoral head appeared, which formed hinge abduction. Increase of the joint space and resolution of the hinge were achieved by arthrodiatasis. As arthrodiatasis can resolve hinge abduction by distraction and reduce mechanical stress, it may be taken into consideration as an option for diseases with hinge abduction.

20/254. Acute epidural hematoma developing during twist-drill craniostomy: a complication of percutaneous subdural tapping for the treatment of chronic subdural hematoma.

    BACKGROUND: This case illustrates that although percutaneous subdural tapping for patients with chronic subdural hematoma (CSDH) is successful and minimally invasive, it can be complicated by acute epidural hematoma. CASE PRESENTATION: A 62-year-old woman presented with headache two months after minor head trauma. Computed tomography (CT) scanning revealed CSDH with mixed density on the right side. Prior to percutaneous subdural tapping, twist-drill craniostomy was performed at the parietal tuber. When the drill-needle reached the dura mater, the patient began to complain of headache, which was followed by altered consciousness. CT scanning disclosed acute epidural hematoma abutting the CSDH; both hematomas were evacuated by emergency craniotomy. At surgery, no definite bleeding source was identified apart from oozing on the dura mater. CONCLUSION: Hemorrhagic complications after percutaneous subdural tapping are rare. The formation of acute epidural hematoma during twist-drill craniostomy has not been reported in the literature. This complication can occur when the blunt tip of the drill-needle remains on the dura mater without penetrating into the subdural hematoma cavity.
