Parathyroid carcinoma is a relatively rare endocrine tumor, accounting for approximately 1 to 5% of patients with primary hyperparathyroidism. Patients with parathyroid carcinomas are often symptomatic, have markedly elevated calcium levels, and have a palpable cervical mass. They are equally distributed between the sexes and usually present 10 years before their benign counterparts. The diagnosis is suspected when the tumor is large, parathyroid hormone levels are high, and a palpable mass is present in the neck. Parathyroid carcinoma is often misdiagnosed preoperatively, suspected intraoperatively, and only confirmed postoperatively. We experienced a case of hyperfunctioning parathyroid carcinoma in a 36 year old man, which was confirmed microscopically. The tumor showed: 1) capsular and blood vessel invasion; 2) frequent mitotic figures in the parenchymal cells; 3) a trabecular pattern, and 4) intervening thick fibrous bands. Immunohistochemical stain of p53 may be one of the useful methods in identifying malignancy of parathyroid gland.

A forty-nine-year-old woman with polycystic disease had a right nephrectomy for what was preoperatively thought to be a polycystic disease, but at surgery turned out to be a tumor based on frozen section. Microscopic examination revealed papillary type, renal cell carcinoma with classical features of adult polycystic kidneys. Radiologic findings revealed multiple cysts in the liver. The clinical recognition of a carcinoma developing in polycystic kidneys is often difficult because of the presence of preexisting large renal masses and occasional hematuria. Renal cell carcinoma should be thought of when confronted with abdominal pain or back pain, severe hematuria, sudden dysuria or a new renal mass occurring in a patient with polycystic kidneys.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

BACKGROUND: UVB is responsible for most of the carcinogenic effects of sun exposure. OBJECTIVE: Aim of this study was to investigate the regulation and intracellular redistribution of p53 protein after UVB irradiation. METHODS: Cultured normal human melanocytes and G361 melanoma cells were used for west-ern blotting and confocal microscopic examination for determining expression and distribution of p53. RESULTS: UVB irradiation increased p53 expression in cultured normal human melanocytes and G361 malignant melanoma cells according to increasing doses of UVB. Furthermore, p53 moved from cytosol to nucleus after UVB irradiation. CONCLUSIONS: UVB irradiation induced overexpression and redistribution of p53 in cultured normal human melanocytes and G361 malignant melanoma cells.

BACKGROUND: Actinic granuloma is an annular inflammatory reaction that develops in skin that has had long-term sun-exposure. OBJECTIVES: The purposes of this study were aimed to characterize the clinical and histopathologic features of actinic granuloma. METHODS: Examinations were performed on eight patients with actinic granuloma regarding the age, sex, duration, clinical morphology, distribution, associated diseases, and treatment and course. Histo-pathologic studies of ten specimens obtained from eight patients were performed with special stains, such as Verhoeff-van Gieson, Gomori-Methenamin silver and alcian blue.

Infection-induced panniculitis develops either through direct inoculation or as a manifestation of sepsis. However, it has rarely been considered as a disease entity within broader context of panniculitis. Moreover, panniculitis associated with a cardiac abscess without the evidence of sepsis has not been reported. We describe a case of infection-induced panniculitis associated with a cardiac abscess. We suggest that infection should be considered as a potentially important etiology of panniculitis, especially in the case of immunosuppression, and in such a case, meticulous efforts should be done to find the focus of infection.

We report a case of histiocytoid hemangioma (angiolymphoid hyperplasia with eosinophilia) in a 60 year-old female patient who was effectively treated with dapsone. The therapeutic effect of dapsone may support the hypothesis that immunologically mediated reactive process plays a role in the pathogenesis of histiocytoid hemangioma.

We report a case of meralgia paresthetica in a 25-year-old man who preferred to wear tight blue jeans. He complained of a tingling sensation and dysesthesia with progressive a nature on the right thigh that had been present for 2 years. The symptoms were relieved after wearing loose trousers.

We report a case of Winkelmann granuloma in a 63-year-old man. nstopathological findings of the biopsy specimens from the lesions of the ear, finger and iliac crest area were compatible with Winkelmann granuloma. Winkelmann granuloma is a rare disorder showing an association with systemic immunoreactive disorders. Although our patient did not have any definite systemic disease, he had characteristic clinical and histopathological findings of Winkelmann granuloma, arthralgia, an elevated erythrocyte sedimentation rate, positivity to the rheumatoid factor and antinuclear antibodies. Therefore, we believed that he was strongly suspected to have an unclassifiable systemic immunoreactive disease.

A total of 73 enucleated eyeballs is reviewed and analyzed clinicopthologically. These eyeballs were selected among the enucleated spceimens that had been removed at the Yeungnam University Hospital during a period of 10 years beginning from 1983 to 1992. Following results were obtained. 1) When the eyeballs were classified according to me direct cause of removal, the neoplasm was the most common single cause accounting for 26 cases(35.6%) out of 73 cases, followed by phthisis bulbi l6 cases(21.9%), trauma 10 cases(13.7%), glaucoma 8 cases(10.9%), inflammation 5 cases(6.8%), staphyloma 4 cases(5.5%), retinal detachment 1 cases(1.4%), Coat's disease 1 cases(1.4%), corneal disease 1 cases(1.4%) and choroidal hemorrhage 1 cases(1.4%). 2) 39 cases(53.4%) were male and 34(46.6%) were female. 23 cases(31.5%) were below 10 years of age, which was the highest rate. 3) The neoplastic lesion included retinoblastoma 20 cases(76.9%) in 26 neoplasms, malignant melanoma 4 cases(15.3%), hemagioblastoma of optic disc 1 cases(3.9%), adenocarcinoma of Meibomian gland 1 cases(3.9%). 4) Retinoblastoma was the commonest intraocular tumor accounting for 20 out of 26 cases, In growth pattern, 80.0% of the tumor grew endophtytically. True rosette were seen 60% of the retinoblastoma.
