Histiocytosis X is characterized by aggregates of Langerhans cells with other inflammatory cells. These Langerhans cells are antigen-presenting cells to T lymphocytes and identified by characteristic morphology, ultrastructural demonstration of Birbeck granules and immunologic reactivity with OKT-6 and HLA-DR antibodies. In this report, the tumor arising in a 2-years-old baby was examined byimmunostaining with several macrophage/dendritic cell markers. The main tumor cells showed cytoplasmic and nuclear staining with S-100 protein and ring-like surface and paranuclear staining with PNA. However, they were negative for follicular dendritic cell marker CD21, macrophage markers lysozyme, Mac 387, alpha-1 antitrypsin and CD68, and interdigitating reticulum cell marker ID4 and ID5. These observations demonstrate the usefulness of S-100 protein and PNA for the identification of Langerhans cells in paraffin-embedded tissue.

The pulmonary cavernous hemangioma is usually from birth and there may be without symptoms until adulthood. Larger or multiple pulmonary angiomata with considerable pulmonary arteriovenous shunts may cause cyanosis, finger clubbing, dyspnea and frequently accompanyingbruit. Recently, we experienced a case of cavernous hemangioma of the lung. A 34-year-old woman was admitted to our hospital for surgical evaluation of a 4 cm solitary, round nodule in the right upper lobe on the chest X-ray and CT scan. She had no symptoms. Laboratory findings are within normal limits except for elevated glucose levels. At surgery, the mass was well encapsulated and easily excised from the peripheral portion of the posterior segment of the right upper lobe. Grossly, it consisted of a 4 cm in diameter, round, soft, sponge-like, hemorrhagic, slightly lobulated mass with a smooth external surface. Microscopically, the mass was composed of vessels, which were thin walled, dilated and filled with blood. The wall of the abnormal vessels was thin and composed of endothelium and fibrous connective tissue with only a little smooth muscle. Immunohistochemically, the wall of the dilated abnormal vessesls showed negative reaction for cytokeratin(low and high) and epithelial membrane antigen but weakly positive reaction for UEA-1 in focal areas.

Background: Post-dural puncture headache (PDPH) is one of the well-known complication of spinal anesthesia. Epidural blood patch is the treatment of choice for PDPH but is rarely used for the prevention of PDPH after spinal anesthesia. The purpose of this study is to observe the effectiveness of epidural blood patch for prevention of PDPH and to evaluate the complications after epidural blood injection. Methods: Three hundred patients (ASA I or II) receiving spinal anesthesia were studied. They were randomly devided into two groups. Patients in Group I, the control group, were maintained in a supine position for 24 hour after spinal anesthesia. Patients in Group II, the study group, received 3 ml of autologous blood in the epidural space after spinal anesthesia. PDPH was evaluated for 5 days. The incidence, location, onset, and duration of headache in the patients presenting with PDPH were measured for 5 days, and the complications following epidural blood patch in Group II were observed for 2 weeks. Results: The incidence of PDPH in group I was 11%, but 0% in group II. There were no specific complications following epidural blood patch in Group II. Conclusions: This study suggest that the 3 ml epidural autologous blood patch is an useful method for the prevention of PDPH in patients with spinal anesthesia.

As a contrast to the surgery described in part I, a lamellar undermining was performed in a conventional way. The sclera was lamellarly undermined on the retinal hole areas which extended at least 3 mm beyond the disc edge of the retinal breaks. If the scleral buckling with a circling element is indicated the location of the undermined area determines whether the circling band must follow the globe's equator or another great circle around the eye, The technique for decreasing a vitreoretinal traction used in this series of cases was that proposed by Schepens. Of 56 surgical procedures for retinal detachment, there was a case of an unsuccessful closure of the retinal break due to fishmouthing of the posterior edge of the break. The technique proposed by Schepens was sufficiently promising. But it has the following drawbacks; difficulties in exact hole localization in a high detached retina, anchoring sutures of the circling band behind the equator and problems to protect the vortex veins from the circling band etc. Our experience since 1978, led us to modify the conventional view, in favor of the circumferential buckling on the equator.

Eosinophilic granuloma of the lung, first described by Farrinaci et al. in 1951, is rare. A 35-year-old male smoker presented with recurrent pneumothorax. Open thoracotomy with bleb resection and biopsy was performed. Microscopically there was histological changes consistent with typical eosinophilic granuloma and intertitial fibrosis. The Langerhans cells showed positive reaction for S-100 protein and typical Birbeck granules in their cytoplasm. A brief summary of histopathological aspect of this disease and a review of literature are presented.

Arteriovenous malformations of the uterus are extremely rare and they occur either in congenital or acquired forms. The most common clinical presentation is abnormal uterine bleeding, which may be aggravated by therapeutic curettage. Because of their rare incidence and clinical importance in management of patients, we report a case of arteriovenous malformation causing serious bleeding during a hysterectomy for uterine leiomyoma. The patient was a 47-year-old multiparous woman who had a history of chronic vaginal bleeding for one year. Numerous anomalous blood vessels draining into the right and left uterine arteries were found on the anterior wall of the uterus and parametrium.

Plasma cell cheilitis is an idiopathic, benign, inflammatory mucosal condition characterized histologically by a dense band-like infiltrate of plasma cells in the upper dermis of the mucosa. In addition to the lips, the disease can affect the penis, vulva, buccal mucosa, palate, gingiva, tongue, epiglottis, and larynx. Plasma cell cheilitis of the lip appears as a circumscribed, flat to slightly elevated, eroded area, usually on the lower lip of an elderly person. We report a 70-year-old man who had a well-demarcated, erythematous, erosive lesion on his lower lip for 1 year. A biopsy specimen showed an upper dermal infiltrate that consisted mainly of plasma cells. Oral griseofulvin, 500mg/day, was begun, and 8 weeks later the lesion showed marked improvement.
