Cervical adenocarcinoma represents approximately 3-6% of the uterine cervical neoplasms. Recently, its relative incidence tends to be increased in contrast to squamous cell carcinoma. Sixty nine cases from 1985 to 1990 diagonsed as adenocarcinoma of the cervix by radical or total hysterectomy were analyzed to know their histopathological characteristics and related prognostic factors. The results wer as follows. (1) The age distribution ranged from 24 to 60 years and the mean age was 44 years and 47 years in adenocarcinoma in situ and invasive adenocarcinoma, respectively. Staging by FIGO classification showed the range from stage 0 to IIb, of which 63.8% was stage Ib. (2) Cases were composed of 7 cases of adenocarcinoma in situ(10%) and 62 cases of invasive adenocarcinomas(90%). The latter included 16 cases of adenosquamous carcinoma and 46 cases of pure adenocarcinoma which showed endocervical, endometrioid, clear cell, minimal deviation adenocarcinoma subtypes. The most frequent subtype was endocervical adenocarcinoma(51%) and the endometrioid subtype showed slightly higher incidence rate(13%) in comparison to the previous studies. (3) Coexistent squamous lesions ranging from mild dysplasia to invasive carcinoma were found in 4 out of 7 cases(57%) of adenocarcinoma in situ and 18 out of 62 cases(29%) of invasive adenocarcinoma. Severe dysplasia and carcinoma in situ comprised most(77%) of them. (4) Analyses of histopathological and clinical characteristics of adenocarcinoma of the uterine cervix revealed positive correlations between tumor size or mucin leakage and depth of invasion. The prognostic factors in relation to lymph node metastasis were considered to be th stage of disease, the size of tumor, mucin leakage in the stroma, and histologic subtypes.

Adenosquamous carcinoma originating in the stomach is relatively rare, and the occurrence of such tumor is interesting with respect to its histogenesis. We describe three cases of gastric adenosquamous carcinoma in a 39-year-old man, a 58-year-old woman and a 52-year-old man. They were grossly classified as Borrmann type III or II, revealing no difference from usual advanced gastric adenocarcinomas. Microscopically three cases showed well or moderately differentiated squamous cell carcinoma component occupying large areas of the tumors. Areas of transition from glandular to squamous epithelium were frequently observed. Metastatic foci in the regional lymph nodes also were consisted of two elements. On immunohistochemical study, CEA immunoreactivity was found not only in adenocarcinoma component but also in squamous cell components, in comparison to cytokeratin which was detected only in squamous areas. The immunohistochemical findings of CEA reactivity in both components, and the presence of microscopic transitional zones support the hypothesis of squamous metaplasia occurring in an already existing adenocarcinoma in the development of adenosquamous carcinoma of the stomach.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchiotoalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Adenoid cystic carcinoma of the lung is histologically and ultrastructurally identical to the salivary gland tumor of the same name and is characterized by infiltrative growth, local recurrence, and usually a prolonged clinical course. We have recently experienced two cases of adenoid cystic carcinoma arising in the lung. Case 1 was a 59 year-old male who presented with cough, fever, and chill of 1.5 months' duration, and case 2 was a 61 year-old male who was incidentally found to have a 3 to 4 cm sized lobulated mass in the right upper lobe. After being worked up, both patients underwent right pneumonectomy. In case 1, a 3x2 cm sized tumor was located in the lower bronchus, partly elevating toward the lumen and partly infiltrating into regional lymph nodes and lung parenchyma showing grayish-white and solid cut surface. Case 2 was a 3.5x3.5 cm sized upper bronchial tumor resembling the former in appearance. Histologically, the tumors were composed of small round hyperchromatic cells, forming solid, cribriform, acinar, or tubular structures. Luminal spaces in tumor cell nests contained PAS-positive mucinous or hyaline material. Among the tumor cells, scattered islands of normal submucosal gland were noticed.

Leiomyosarcoma of the soft tissue is a well-defined and characteristic entity histologically, but cytomorphological studes are lacking. A correlative cytological study of 2 cases of leiomyosarcoma is presented. The smears from case 1 were rich in tumor cells and most cells were arranged in large sheets or clusters. The cells showed round to oval nuclei containing fine chromatin and small prominent nucleoli. The smears from case 2 were moderate in cellularity with loose clusters or isolated cells. The characteristic blunt-ended and cigar-shaped nuclei containing coarse chromatin and prominent nucleoli were identified in case 2. Nuclear atypia, prominent nucleoli and high cellularity permit diagnosis of malignancy, although the atypia is generally less pronounced than in the histology. The cytological diagnosis of leiomyosarcoma may be auxiliary in the diagnosis of recurrence or metastasis in the patients with alleged leiomyosarcoma.

The purposes of this research were to assess the quality of worklife of university foodservice managers and workers by operation type, and to investigate the characteristics of demographic variables in university foodservice employees. A questionnaire was administered to 27 managers and 180 personnels who are working in 9 university foodservice facilities. And 21 managers and 160 workers were responded with a response rate of 78% and 89%, respectively. Statistical data analysis was completed using the SPSS programs for descriptive analysis, ANOVA, T-test and SNK test. The results of this study can be summarized as follows : 1. Almost all respondents were female(87%), 40.5 percent of the respondents were between 40 to 49 years of age, 42.9 percent of the respondents had been in their current job between 2 to 5 years, and 55.2 percent of the respondents eamed pays between 500,000won to 800,000won per month, Only 42.6% percent of the respondents were full-time employee. 2. The mean scores for the quality of worklife was 3.07 on a 5-point scales of 1=disagree very much and 5 = agree very much. 3. Factors receiving the higher ratings included "optimum levels of work variety"(3.83), "positive attitude toward work"(4.14), and "cooperative relationship with coworkers"(4.22). But respondents were least satisfied with "promotion"(2.07), "temperature of workplace"(2.17) "rest time"(2.25), and "pay"(2.28) factors. 4. There was a significant difference in the perception of the quality of worklife according to the operation type(self-operated, contracted, and rented management), but no difference was noted by position(managers vs workers) Results can be user to develop intervention and training strategies for enhancing positive attitude and the quality of work of employees.
