Generalized perforating granuloma annulare is a rare variant of granuloma. annulare, which was first described by Duncan et al 1) in 1973. A 21-year-old female had hundreds of 3 to 5mm papules over the whole body, which were mainly distributed in the extremities and trunk since three months ago. Individual papules developed a central umbilication with a peripheral collarette of scale. Histopathologic examination showed an epidermal perforation and transepidermal elimination of necrobiotic material. The epidermal perforation communicated with areas of necrobiotic collagen surrounded by palisading granulorna in the dermis. We treated her with oral prednisolone and dapsone, but there was no clinical improvement.

Subcutaneous form of neuromuscular hamartoma is extremely rare and histologically different from the conventional neuromuscular hamartoma of the peripheral nerve or benign Triton tumor by an indistinct nodular growth with ill-defined margin and marked collagen interposition. It is usually not associated with a major nerve. We report a case of subcutaneous neuromuscular hamartoma developed in the forehead of 24-year-old man. The tumor showed proliferation of dense, hyalinized fibrous tissue, in which single or group of mature skeletal muscle fibers and nerve fibers were haphazardly intermixed. Recognition of abnormally arranged muscle and nerve fibers is important not to miss this lesion.

The glomus coccygeum is a glomus body located close to the tip of the coccyx. Because of its large size and multiple anastomotic channels, it mimics glomus tumor. It is very unfamiliar to the pathologits. We describe a case of glomus coccygeum incidentally found associated with coccygeal dimple from 5-month-old infant.

Intravascular injection of hydrogen peroxide produces oxygen microbubbles suitable for echocardiographic contrast enhancement. To evaluate the effect of a method of myocardial contrast 2-D-echocardiographic delineation of myocardium during acute coronary occlusion, injection of a fresh mixture of 2ml of 0.2% H2O2 and 1ml of heparinized dog blood into aortic root were made in 12 poenchest dogs 10 minutes after occlusion of left anterior descending coronary artery distal to the first diagonal branch and left ventricular short axis 2-D echocardiographic images at the midpapillary muscle level were obtained. On injection of H2O2 blood mixture normally perfused myocardium was enhanced in echodensity but the area of malperfusion did not change in echodensity. The borderlines between the area of normal perfusion and malperfusion was well delineated. The malperfused area measured at mid papillary muscle level by planimetry area method was 29.7+/-6.0% and 32.6+/-6.7% by endocardial circumferential length method. There was a linear correlation between planimetric estimate of area of malperfusion by H2O2 contrast echocardiography and visual determination of regional wall motion abnormality by 2-D echocardiography(r=0.93, P<0.001). There was no change in heart rate before, during and after H2O2 injection. Infection of H2O2 blood mixture caused bradycardia(8.3%), second degree A-V block(16.6%) and ventricular fibrillation(8.3%). H2O2 clearance was achieved in 3-10 minutes. These findigs suggest that H2O2 enhanced myocardial contrast ehocargiography using 2ml of 0.2% H2O2 and 1ml of blood muxture is an accurate, reproducible, real-time in vivo method of quantifying the extent of myocardial perfusion defect during acute coronary occlusion in dog.

We report a case of primary cutaneous cryptococcosis on the left knee of a 67 year-old woman. She had a large ulcerated and indurated plaque with yellowish purulent exudates on her left knee. A histopathological examination from the lesion showed numerous encapsulated, round spores. Cultures from the lesion showed the presence of Cryptococcus neoforrnans. This may have resulted from an immunosuppressive state due to long-term use of oral corticosteroids.

Korean Journal of Pathology 1997;31(2):174-178
An ossifying fibromyxoid tumor of soft parts is a rare, recently described, fibro-osseous neoplasm of uncertain histogenesis. It occurs most frequently within the subcutis or skeletal muscle of the extremities. Its biologic behavior is generally regarded as benign with at worst a locally aggressive clinical course. But, atypical and malignant variants have been recently reported. Herein we report a case of a benign ossifying fibromyxoid tumor which occurred in the left upper back of 41-year-old man. The tumor is composed of uniformly round or polygonal cells arranged in cords or nests which are separated by myxoid and hyalinzed fibrous matrix and associated with irregular bony trabeculae. The tumor cells are strong positive for vimentin. Ultrastructural findings and a review of literatures are added.
