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: At least 30 per cent of diabetics, which is said to comprise over 3% of general population in Korea, have one or more cutaneous complications during the course of the disease. These skin changes may be the consequences of microangiopathy, arteriosclerosis, direct metabolic disturbances and/or the sequelae of chronic therapy. OBJECTIVE: We tried to observe certain cutaneous and nail changes in diabetics and to relate them with systemic complications, blood sugar level and duration of diabetes. METHODS: During the period of 12 months from March, 1992 to February, 1993, a total of 1858 outpatients diagnosed as diabetes mellitus at Eulji General Hospital were examined. RESULTS: The cutaneous manifestations are observed in 79.5% of diabetics examined and cutaneous infections are the most prevalent(52.3%). Pruritus(p<0.01), anogenital pruritus(p<0.01), peripheral dedema(p<0.05) are more common in females and infections, shin spots, finger pebbles(p<0.01) are more common in males. Systemic complications are observed in 50.7% and the cutaneous manifestations are observed more frequently in patients with systemic complications(p<0.05). Shin spots, diabetic foot, peripneral edema diabetic bullosis are observed frequently associated with systemic microangiopathic complications such as retinopathy, nephropathy and neuropathy(p<0.01). There is a significant correlation between blood sugar level and fungal infections and anogenital pruritus(p<0.01). The frequencies of shin spots, diabetic foot and diabetic bullosis increase with the length of time diabetes has been present. Nail changes are observed in 39.6% of diabetics and onychomycosis is the most frequent(34.5%). CONCLUSION: It is suggested that cutaneous shgns especially fungal infections in diabetics are on the increase in Korea. A variety of skin conditions are encountered with diabetes mellitus and the dermatologist may be able to make a significant contribution in the control of diabetes mellitus by identifying skin signs and conditions as diabetic complications.

A case of congenital self-healing histiocytosis was studied with S-100 antibody and electron microscopy. Many tumor cells were positive for S-100 protein and a few contained Birbeck´s grandles and dense bodies. A pathlogic fracture was first noticed on the seventh day. The lesions involuted spontaneously by the end of a weeks

Synovial chondromatosis is a condition of metaplastic and focal formation of cartillage in the intimal layer of synovial membrane. The etiology is unknown. The cartilagenous foci become pedunculated and may be sequestrated into the synovial cavity to form loose body. The center of focus may calcify and ossify. Of the ten cases of synovial chondromatosis experiences by the authors, five cases invo1ved the knee joint, one case both knee joint, two cases the hip joint, two cases the elbow joint, one case the wrist joint. The diagnosis of synovial chondromatosis was made by the histopathological finding of the excised masses.

In this report, a case of a 70-year-old man with a large ganglion cyst formed after anterior transposition of the left ulnar nerve is presented. Three months after the index surgery, the patient presented with a painless superficial ovoid, soft mass measuring 5x4x2 cm in size located at the posteromedial aspect of the left elbow, the previously operated site. Magnetic resonance imaging showed a well demarcated cystic mass with a stalk connecting to the elbow joint. Excisional biopsy was performed and pathologic findings showed that the cystic wall had no definite lining cells with myxoid degeneration compatible with findings of ganglion cyst.

The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were purified through the FPLC system using Mono Q column chromatography. The polyclonal antibodies to the enzymes were produced in BALB/c mice. Immunolocalization studies revealed that both cysteine proteases were distributed at the linings of excretory bladder and excretory concretions of the metacercariae. It was suggested that the excretory epithelium of P. westermani undertake the secretory function of metacercarial cysteine proteases, in addition to its role as a route for eliminating waste products.

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.

9.Valproate-induced Hyperammonemic Encephalopathy: A Case Report.
Brain & Neurorehabilitation 2013;6(2):86-89
Valproate is widely used because of broad spectrum of action, but it can produce an encephalopathy resulting from hyperammonemia even at the therapeutic range of valproate and is called as valproate-induced encephalopathy (VHE). Delay in recognition of VHE can result in the development of potentially life-threatening complications. Fortunately, it is reversible with discontinuing valproate. A 65-year-old man became progressively lethargic with impaired gait and poor cognitive function while taking valproate as alternative to zonisamide. Routine investigations of admission profiles were performed but revealed no abnormalities. Next, we checked serum ammonia level to identify other possible causes and detected hyperammonemia despite the therapeutic range of valproate in the absence of any abnormalities in liver enzymes. On cessation of valproate, he has achieved dramatic clinical improvement including the reversal of hyperammonemia. We confirmed the diagnosis of VHE. This emphasizes the importance of rapid diagnosis and proper management of VHE in order to prevent the neurological damage and minimize complications.

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.
