Hyun Tae LEE ; Hyeon Dong SHIN
Mycobiology 2000;28(1):39-46
Eight species of Marssonina parasitic on 21 species of host plants from Korea are described and illustrated. They are Marssonina brunnea (Ellis & Everh.) Magnus, M. capsulicola (Rostr.) Magnus, M. celastri H.D. Shin & H.T. Lee, M. coronaria (Ellis & Davis) Davis, M. fragariae (Lib.) Kleb., M. juglandis (Lib.) Magnus, M. rosae (Lib.) Died. and M. sennenis (Gonz. Frag.) Vassiljevsky & Karak. Of these, M. capsulicola and M. coronaria sometimes poss three-celled conidia and M. sennenis is characterized by a short appendage at the basal end of the conidia. Morphological features of conidia and host ranges were of taxonomic values for species delimitation.

Korean Journal of Pathology 1988;22(2):169-179
Malignant mixed mesodermal tumor (MMMT) of the ovary is endometrioid tumor containing epithelial and mesenchymal components. The mesenchymal component may be homologous, in which case the term carcinosarcoma is often used, or heterologous, containing cartilage, striated muscle, osteoid, bone, or fat, or combination of these elements. MMMT usually afflicts the postmenopausal woman and occurs more often in the nulliparous female. The disease is usually advanced (stage III) when diagnosed. Cliniopathologic data were presented for 3 cases of MMMT of the ovary with review of literatures. Clinical history substantiated previous reports in postmenopausal women wit this tumor. Symptoms were the same as for ovarian malignancy in general. All the patients presented wit stage II disease, according to the International Federation fo Gynecology and Obstetrics (FIGO) classification. Two patients died of tumor 4 and 10 months after operation, respectively. One patient had been alive at 2 months after operation. None of 3 cases demonstrate evidence of endometriosis in the remaining ovaries. Microscopically, periodic acid-Schiff (PAS)-positive, diastase-resistant hyaline droplets were found frequently in undifferentiated mesenchymal stroma and epithelial structures. The clinical significance and origin of the hyaline droplets in MMMT should be further explored.

Korean Journal of Pathology 1988;22(3):340-347
A case of desmoplastic fibroma of mandible in a 18 years old woman is presented. She had complained progressive swelling of right mandible for 4 years. Radiographically, a multilocular radiolucent of right hemimandibulectomy showed multinodular external surface without cortical destruction. Cut surfaces revealed grayish white, fibrous homogeneous appearance with firm consistency, sparing head portion. The maximum diameter of the tumor was 13 cm. Microscopically, the tumor was composed of interlacing bundles of monomorphic spindle-shaped cells with abundant intercellular collagen. Ultrastructurally, most tumor cells were fibroblastic-like cells with abundant RER and cytoplasmic fibrils, but a few disclosed transition to myofibroblasts. However, no fully developed myofibroblasts were seen.

A boy (Hellman dental age III B) with mandibular prognathism was treated by means of the labiolingual appliance and the chin cap. Following results were obtained; 1) Except the problem of development, most of treatment objectives were achieved after 8 months of active treatment. 2) The axial inclinations of upper and lower incisors were changed by the treatment. 3) The most notable change was the reduction of genial angle. 4) The patient has retained the good occlusal stability till after 18 months of retention.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

Disseminated superficial actinic porokeratosis (DSAP) is one of the recently found skin disorderes, which was differentiated from classicaI porokeratosis (Mibelli) and senile keratosis etc. in view of clinical features and hietogenesis by Marvin E. Chernosky on 1967. The one was 60 years old female patient, who had been suffered from multiple dark-brownish keratotic uniform minute papules on dorsa of the hands, forearms and neck with accompanying itching sensation since about 20 year's old of her age. The another one was 38years old housewffe, wha had been suffered from same lesions of the former on the face, neck, extremities especially sun-light exposed area. In both cases, skin lesions were exacerbated during each summer season and increase in numbers of the skin lesions with more severe itching sensation. Chernosky postulated none of a dark-sklnned race affording natural protection against sun-light had skin lesion of D S A P, we were abIe to find out two cases of typical D S A P ih the Korea.

Because neuroblastoma is predominantly a tumor of childhood, patholgists and clinicians tend to exclude it from differential diagnosis when the patient is an adult. The diagnosis of neuroblastoma by light microscopy can be difficult because of similarities between neuroblasts and cells of other round cell neoplasms. The fine structural features of neuroblastoma is distinctive and is valuable in its diagnosis. We present 2 cases of neuroblastoma and a case of ganglioneuroblastoma arising in adults with their ultrastructural findings.

TO evaluate the histopathologic features of gastric mucosa by Helicobacter pylori (HP), we reviewed 70 endoscopically biopsied chronic gastritis and peptic ulcer. The results are as fonows. l. HP was detected in 923% (48/52) of active gastritis, 8l8% (9/l l) of peptic ulcer and l43% (1/7) of chronic gastritis. The prevalence of HP infection was significantly higher in active gastritis and peptic ulcer than chronic gastritis (P<0005). 2. The infiltration of intraepithelial neutrophil of the 58 HP-positive cases was significantly more than of the l2 HP-negative cases (P<0005). 3. The infiltration of neutrophil and chronic inflammatory cells in the lamina propria of the 58 HP positive cases were significantly more than of 12 HP-negative cases (P<0.005, P<0.01) 4. The gastric epithelium of 58 HP positive case showed characteristic degenerative change, such as epithelial pits (93.l%), irregular surface (84.4%), individua1 cell drop-out (46.5%) and microerosion (27.6%). The similiar changes were not seen in l2 HP-negative cases. In summary, HP is significantly correlated with inflammatory reaction of the gastric mucosa. It is also significantly correlated with the epithelial degenerative changes that is considered to the precursor of peptic ulcer.

Congenital subglottic stenosis of the larynx is one of the most common cause of chronic airway obstruction im infancy and childhood. It is defined as narrowing of the space bounded inferiorly by the inferior margin of the cricoid cartilage amd superiorly by the insertion of the fibers of the conus elasticus into the true vocal cords. In case we experienced was a female full-term baby delivered by Cesarean section. The stenosis was believed by hypertrophy of stromal soft tissue and cricoid cartilage in the subglottic area. The lesion was associated with tracheoesophageal fistula of H1 type. A brief review of the literature was done.
