1.Leiomyoma of the Skin: clinicopathological study of 19 cases.
Korean Journal of Pathology 1996;30(6):515-522
Nineteen cases of leiomyoma of the skin were examined clinicopathologically. This group included 12 cases of angioleiomyoma, 5 cases of solitary piloleiomyoma, and 2 cases of multiple piloleiomyomas. 1) All twelve angioleiomyomas occured as solitary lesion in the extremities. There was a preponderance in females with a ratio of 2:1. The ages of patients ranged from 24 to 80 years and only one was below the age of 30 years. Six tumors were either painful or tender. Nine tumors in subcutaneous fat were shelled out at surgery. All tumors did not exceed 4cm in diameter. Histologically they could be separated into ten cases of the solid type and two cases of venous type according to Morimoto's classification. Although actin or desmin was easily detected in all tumors, the diagnosis was better made using a combination of hematoxylin-eosin and Masson trichrome stains. 2) Five cases of solitary piloleiomyoma were slow-growing intradermal nodules. The ages of patients ranged from 10 to 77 years. All five cases were female. The lesions were located on the extremities, back and sholuder. Pain or tenderness was present in 3 cases among these tumors. Histologically, all tumors were characterized by subtle poorly circumscribed proliferation of benign smooth muscle in the dermis. 3) Two multiple piloleiomyomas from two female patients, aged 50 and 40 years, were situated on the shoulder and thigh, respectively. Pain was induced by change of temperature in the shoulder lesion. Histologically they were identical to the solitary piloleiomyoma.

Most instances of choriocarcinoma of the ovary are gestational in origin. In contrast, nongestational choriocarcinoma of the ovary is an exceedingly rare primary germ cell neoplasm that has worse prognosis than gestational neoplasm. We report a case of pure nongestational choriocarcinoma of the ovary in view of the rarity of its kind. The patient was a 35-year-old Korean unmarried woman who had suffered from vaginal bleeding and feeling of abdominal inflation for two months. The X-ray studies and CT scanning revealed a child head sized cystic mass on the right pelvic cavity and multiple nodular densities in both lung fields and the liver. The mass in pelvic cavity was excised and histologically confirmed to be a nongestational pure choriocarcinoma, arising from the right side ovary.

PURPOSE: Henoch-Schonlein purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. METHODS: 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) for 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) for 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. RESULTS: Complete remission rate of nephrotic syndrome was 5S.8% in CsA, 57.1% in RFP and 38.4% in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was 88.2% in CsA, 85.7% in RFP and 84.6% in AZA group. Disappearance rate of hematuria was 58.8% in CsA, 57.1% in RFP and 46.2% in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA(29.4%), none RFP(0%) and 2 AZA group(12.4%). Improvement on histologic immune-deposition was seen in 15 CsA(88.2%), 6 RFP(85.9%) and 4 AZA group(30.8%). CONCLUSION: In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant inprovement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and RFP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.

Congenital mesoblastic nephroma(CMN) is an important differential diagnosis of a renal mass occurring in the newborn or in early childhood. It was first described by Bolande as a separate disease entity distinct form Wilms' tumor. In 1974, Beckwith has predicted that this tumor has a pathologic spectrum with classic congenital mesoblastic nephroma at one extreme, unequivocally mallignant spindle cell sarcomas at the other, and intermediate "gray zone" lesions of indeterminate biologic significanse. In 1986, Joshi has described "atypical mesoblastic nephroma" as a potentially aggressive variant of CMN, which shows atypical gross and microscopic features such as hemorrhage, necrosis, high cellularity, and mitotic index. We report of a case of atypical mesoblastic nephroma presenting in a 38 days-old male infant. Grossly, the tumor involved the upper and midportion of the left kidney. On section, the cut surface was fleshy, grayish-white, and homogeneous. Microscopically, the tumorshowed high degree of cellularity and arrangement of fusiform cells in sheets and vague interlacing bundles. The individual tumor cells showed fusiform to oval nuclei, indistinct scanty pale-eosinophilic cytoplasm and many mitotic figures.

Though the primary carcinoma of the vermiform appendix is rare, the secondary carcinoma of the vermiform appendix is extremely rare. About fourty cases have been reported through the world. The breast is most common primary site, and adenocarcinoma is most common form. The metastatic carcinoma of the vermiform appendix, from squamous cell carcinoma of the uterine cervix, were extremely rare. The authors experienced a case of metastatic squamous cell carcinoma of the vermiform appendix, in thirty-two years old housewife. She was diagnosed with carcinoma of the uterine cervix on December, 1983, and treated with a radical hysterectomy on February, 1984, at Chicago, and with a radiation therapy. She had been suffered from palpable masses on left axilla and left neck region, and and coughing and chest pain. After an excision biopsy, on August, 1984, she showed intestinal obstruction sign including abdominal distension with abdominal pain. A right-sided hemicolectomy was performed on November, 1984. During gross examination, the wall of the distal portion of the vermiform appendix was moderatery thickened, and showed homogeneous light yellow cut surface. On microscopic examination, there were clusters of tumors that had negative stained preparations. On electron microscopic examination, the secretory granules were not found, and the characteristics of squamous cells, including intercellular spaces, desmosomes and tonofibrils, were noted.

Turner's syndrome results from complete or partial monosomy of the X chromosome and is characterized by hypogonadism or related other congenital anomalies in phenotypic females. In these patients, there are failure to develop normal secondary sex characteristics, amenorrhea, or short stature at puberty and the ovaries are reduced to atrophic fibrous strands devoid of ova and follicles(streak gonads). Individuals with this condition are particularly prone to the development of gonadoblastoma. For this reason, the gonads should be early removed and supplemental estrogen therapy given. We experienced a case of Turner's syndrome, 45, XO/46, XY karyotype in a 20-year-old phenotypic female complained an amenorrhea. On the exploratory laparotomy, the right gonadal mass is sevearly adhered to the adjacent organs and measures 8 x 5 x 5 cm in dimension and 75gm in weight and shows multiple foci of hemorrhage with necrosis. The left streak gonad measures 3.5 x 2 x 1.5 cm in dimension and shows multiple foci of calcification. Microscopically, the right gonadal mass reveals malignant mixed germ cell tumor, composed of endodermal sinus tumor, composed of endodermal sinus tumor with dysgerminoma and gonadoblastoma. The left streak gonad consists of mainly dense fibrous connective tissue and shows some foci of calcification associated with gonadoblastoma. On immunohistochemical and special stainings, the cytoplasm and hyalin droplets of the endodermal sinus tumor component reveal strong positivity to the a-fetoprotein and PAS. After removal of both gonads, the serum level of the a-fetoprotein is markedly down from 1742ng/ml to 2.6 ng/ml.

In this study, the trypsin gene (bgtryp-1) from the German cockroach, Blattella germanica, was cloned via the immunoscreening of patients with allergies to cockroaches. Nucleotide sequence analysis predicted an 863 bp open reading frame which encodes for 257 amino acids. The deduced amino acid sequence exhibited 42-57% homology with the serine protease from dust mites, and consisted of a conserved catalytic domain (GDSGGPLV). bgtryp-1 was determined by both Northern and Southern analysis to be a 0.9 kb, single-copy gene. SDS-PAGE and Western blotting analyses of the recombinant protein (Bgtryp-1) over-expressed in Escherichia coli revealed that the molecular mass of the expressed protein was 35 kDa, and the expressed protein was capable of reacting with the sera of cockroach allergy patients. We also discussed the possibility that trypsin excreted by the digestive system of the German cockroach not only functions as an allergen, but also may perform a vital role in the activation of PAR-2.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.
