A case of calcifying synovial sarcoma, occuring in the deep muscle fascia of the left thigh is reported. The presence of extensive calcification in synovial sarcoma is a favorable sign for prognosis. The patient was a 31-year-old female. The tumor mass had been present for 3 years, accompanying local tenderness. X-ray revealed a soft tissue tumor with central calcification, which was located between the adductor magnus and brevis of the left thigh. The tumor size was 7 x 5.5 cm. There was no connection with the knee joint or the femur. Grossly, the tumor was a relatively well circumscribed hard tumor with massive calcification. Microscopically, the tumor was composed of predominantly spindle cells with accompanying hyalinization, numerous spherical concretions and ossification. The epithelial component was not clearly noted. Mitotic figures were rarely noted in the densely cellular area. Immunohistochemical staining for EMA, S-100, vimentin, and carcinoembryonic antigen was negative while vimentin and cytokeratin were weakly and focally positive. EM study revealed multiple desmosome-like calcification intercellular junctions with a slit-like lumen and an incomplete basal lamina, which suggest that tumor show these cells were undergoing epithelia] differentiation. Above evidence suggest that this tumor is a synovial sarcoma associated with a large area of calcification, a so called calcifying synovial sarcoma. No recurrence was noted in one and half years of follow up.

Obstruction on the urinary tract eventually results in damage to the kidneys and loss of function. The questions that concern the clinician are the degree of nephron loss in that kidney and the potential for recovery following the relief of obstruction. 99mTc DMSA accumulates in tubule cells and has been proposed as a marker of the tubular mass. The authors estimated the renal uptake ratio of 99mTc DMSA for the degree of nephron loss corresponding to duration of hydronephrosis following left ureteral ligation in 5 NewZealand white rabbits and the potential for recovery following percutaneous nephrostomy of hydronephrosis in 24 rabbits. While the renal uptake ratio of 99mTc DMSA of the kidney with unilateral hydronephrosis following ureteral ligation reduced dramatically within 24 hour, that of the opposite healthy kidney increased, and the total renal uptake ratio was same as normal functioning kidneys before ureteral ligation. Upon ureteral release, there was no evidence of definite recovery or impairment in the experimental kidneys for 5 days. The authors conclude that a combination of ureteral release and administration of some drugs such as renal vasodilator or diuretics is an appropriate treatment for the recovery of function in unilateral hydronephrosis.

Plexiform schwannoma is a relatively rare, benign peripheral nerve sheath tumor that can be located either in the deep soft tissues or in the dermis or subcutaneous tissue. This tumor may occur singly or as multiple lesions and may be localized to one anatomic site or diffusely distributed. Plexiform schwannoma should be differentiated with plexiform neurofibroma or other plexiform malignant tumors. We describe a case of a 6-year-old patient with multiple cutaneous plexiform schwannomas who had no other stigmata of neurofibromatosis 1 or family history suggesting a genetic disorder. The histopathological study revealed a tumor composed of multiple intradermal or subcutaneous interlacing and interconnecting fascicles and nodules that vary in size and shape. Characteristic Antoni A type cellular tissue showing frequent nuclear palisading and Verocay bodies were observed within well circumscribed elongated nodules.

A survey for nematode and cestode parasites of rodents in Korea has been carried out at the areas of Chulwon, Kumwha, Pochon, Paju and Chungpyong, Kyunggi-Do. A total of 300 rodents of seven species was examined, comprising of 219 A. agrarius, 33 R. norvegicus, 8 R. alexandrinus, 14 Mus musculus yamashinai, Microtus fortis pellceus, 21 Crocidura russula and a Cricetulus trition nester. The following fifteen species belonging to thirteen genera were identified: NEMATODA: Heterakis spumosa, Syphacia obvelata, Nippostrongylus muris, Protospirura muris, Capillaria hepatica, Capillaria sp., Heligmosomum sp., Heligmosomoides sp., Rictularia sp. and Gongylonema sp. CESTODA: Hymenolepis nana, Hymenolepis diminuta, Raillietina coreensis, Paranoplocephala sp. and Cysticercus fasciolaris(the larva of Taenia taeniaeformis).

Nevus lipomatosus cutaneous superficialis is a very rare skin disease, which usually is present at birth. The lesion shows groups of asymptomatic soft papules or nodules, which have a smooth or folded surface and are skin colored or yellowish. The area of predilection is the pelvic girdle (especially the buttock and sacrococcygeal areas). Microscopically, nevus lipomatosus cutaneous superficialis reveals groups of etopic fat cell nests within the dermis. Only one case was reported in Korea(1969). The authors observed a case of typical nevus lipomatosus cutaneous superficialis. The patient was 19 year-old male, who ha,ve had asymptomatic soft papules and nodules on the buttock, lower back and scalp since 14 years of his age. Routine laboratory findings were within normal limit. Histopathological findings showed etopic fat cell nests within mid and lower dermis (Fig. 3) Diagnosis was confirmed by clinical and histopathological findings. Litercature was briefly reviewed for the discussion.

Anetoderma or macular atrophies is a localized laxity of the skin, resulting from defect in the elastie tissue of the dermis. This defect produces a clinical picture consisting of circumscribed area of soft, thin and wrinkled skin, which can be pushed easily into the subcutaneous tissue by the examining finger. When the lesions appear without any preceding recognizable disorder, they considered to be primary macular atrophies. In this group, based on whether an inflammatory reaction has occurred before the appearance of macular atrophy, two types aer generally acknowledged: Anetoderma of Jadassohn-Pellizali has a preceding inflammatory reaction, whereas anetoderma of Schweninger-Buzzi has had no preceding discemible inflammatory changes. The authors observed a case of anetoderma of Jadassohn-Pellizali in a 34 year old male when showed bean to coin sized rovnd or oval, thin, soft and wrinkled macules on the trunk, shoulder and upper extremities. About 3 years ago, erythematous macules developed which extended for several months to reach a size of l.5 to 2.5 cm. Slowly each lesion faded from the cener to outward Ieaving soft and wrinkled macules(Fig.l). Routine physical and laboratory findings were within-normal-limit. Histopathological findings showed scanty and fragmentation of the elastic fiber of the dermis and perivascular non-specific inflammatory cell infiltration. (Fig. 2, 3 & 4) Diagnosis was confirmed by clinical and histopathological findings. Literature was briefly reviewed for the discussion,
