  • Background: To compare the pathological findings and oncologic outcomes of stage IA cervical carcinoma patients, between adenocarcinoma and squamous cell carcinoma cases. Materials and Methods: A total of 151 medical records of stage IA cervical carcinoma patients undergoing primary surgical treatment during 2006-2013 were reviewed. Information from pathological diagnosis and recurrence rates were compared with descriptive statistical analysis. The Kaplan-Meier method and Cox proportional hazards model were used for survival analysis. Results: The median age was 48.9 years. There was no significant difference in rates of lymph node, parametrium, uterine, vaginal, or ovarian metastasis, when comparing adenocarcinoma with squamous cell carcinoma. Overall recurrence rates of adenocarcinoma (5.7%) and squamous cell carcinoma (2.6%) were not statistically significant different, even when stratified by stage. When comparing progression free survival with squamous cell carcinoma, adenocarcinoma had an HR of 0.448 (0.073-2.746), p=0.386. Conclusions: Microinvasive adenocarcinoma of cervix has similar rate of extracervical involvement and oncologic outcomes to squamous cell carcinoma.

  • Basal cell adenocarcinoma is an epithelial neoplasm which is cytologically and histomorphologically similar to basal cell adenoma but is different because of the infilitrative growth. This tumor, a rare salivary gland tumor newly classified as basal cell adenocarcinoma by the WHO in 1991, is infiltrative, locally destructive and tends to recur but metastasis is less common. The differential diagnosis includes basal cell adenoma, adenoid cystic carcinoma, and basaloid squamous carcinoma. Nearly 90 percent of these tumors occurr in the parotid gland and can be classified into low grade carcinomas with a relative good prognosis. Basal cell adenocarcinoma of minor salivary gland is very rare and has a less favorable clinical course compared with that of the major salivary glands. This is a case of basal cell adenocarcinoma occurring at the minor salivary gland of the soft palate. We treated this patient with block excision and adjunctive radiation therapy.

  • This study is a report about a specific patient whose primary stomach adenocarcinoma metastasized to uterine cervix adenocarcinoma. A thirty-nine year old female patient was initially diagnosed as having metastatic adenocarcinoma in the supraclavicular lymph node. Upon further examination, she was diagnosed with stomach adenocarcinoma. 8 months later, a cervix punch biopsy was performed. The stains used for examination were H&E stain, PAS stain, Alcian blue stain, Mucicarmine stain, Papanicolaou's (Pap.) stain, and as immunohistochemical stains, cytokeratin 7 and 20 were done. In the H&E stain, the tumor cells showed prominent and eccentric nuclei, thin nuclear membrane in abundant mucous cytoplasm, and cylinder shape. In the PAS stain, intracytoplasmic mucin vacuoles were stained with pink, and in Alcian blue and Mucicarmine stains, intracytoplasmic mucin vacuoles were stained with blue and red. As in the above results, she was diagnosed with undifferentiated adenocarcinoma. As found on the cytologic smear preparation of the uterine cervix stained by Papanicolaou's stains, the background was relatively clear, the number of malignant cells was relatively low, and large and eccentric nuclei in abundant cytoplasm were observed. Upon observing the tissue preparation of the uterine cervix biopsy by H&E stain, a clear background, large and eccentric nuclei, and a signet ring cell types were observed, and the number of malignant cells were fewer than in the primary uterine cervix adenocarcinoma. The vacuoles in cytoplasm were observed. The nuclear membrane and chromatin were thick and very rough, and upon observation by cytokeratin 7 and 20 of immunohistochemical stain, the tumor cells indicated a positive rate of 70% and 20%, respectively. According to these results, also she was diagnosed with metastasized uterine cervix adenocarcinoma. In summary of the results of pathologic findings on stomach biopsy and cytologic, histopathologic, and immunohistochemical finding on uterine cervix biopsy, the adenocarcinoma of her uterine cervix could assert the adenocarcinoma of signet ring cell type that was metastasized from the primary undifferentiated adenocarcinoma in stomach.

  • Basal cell adenocarcinoma is a extremely rare low grade malignancy of the salivary gland. It is composed of basaloid cells with dark cell, light cells and pale cytoplasm which shows infiltrative growth pattern into adjacent glandular parenchyme. The pathophysiology of basal cell adenocarcinoma is not well known. First hypothesis is a malignant transformation of the monomorphic adenoma and second one is a de novo origin. Metastasis to the regional lymph nodes is rare. Recently, we have experienced a case of basal cell adenocarcinoma with neck metastasis after previous superficial parotidectomy. For this reason we report this rare case discussed with references.

  • Primary clear cell adenocarcinoma of uterine cervix is rare and cytomorphology in the vaginal smear have not been previously described in Korean literatures. The cytologic characteristics of clear cell adenocarcinoma of the uterine cervix include : malignant cells with abundant, finely vacuolated cytoplasm ; hobnail appearance, and distinctive basement membrane-like hyaline materials within cellular aggregates. A 36-year-old woman presented with vaginal bleeding. Cytologic examination of vaginal smear and histopathologic examination of a radical hysterectomy specimen allowed the diagnosis of hemorrhagic tumor in the uterine cervix as a clear cell adenocarcinoma. Cytologic findings were very characteristic. The tumor cells had abundant, pale, finely vacuolated cytoplasm with indistinct cytoplasmic membrane. The nuclei were round to oval with finely dispersed chromatin. Extracellular basement membrane-like hyaline substance, which stained a light green color in Papanicolaou's preparation, was frequently observed within the cancer cell clusters.

  • Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (extranodal MZL) is a distinct subgroup of non-Hodgkin's lymphoma. Pulmonary extranodal MZL is a rare entity and accounts for less than 0.5% of primary pulmonary malignancies. Only a few cases of simultaneous occurrence of lung cancer and pulmonary extranodal MZL have been reported. A 60-year-old woman was referred to our hospital with a pulmonary nodule. She was diagnosed with lung adenocarcinoma by percutaneous needle biopsy. The protrusions into the left main bronchus were found by accident while performing bronchoscopy during lung cancer evaluation. The bronchial lesions were diagnosed as extranodal MZL. Although the patient underwent surgical resection for the lung adenocarcinoma, the pulmonary extranodal MZL was left untreated; it was monitored during follow-up visits. To our knowledge, this is the first report of synchronous lung adenocarcinoma and primary extranodal MZL of the main bronchus.

  • Chelidonii Herba (Baekgulchae in Korean: CHE), a commonly used herb in Korea, Japan and China, is widely used in the treatment of stomach cancer, jaundice, gastric ulcer, edema and pain of stomach. In the present study, we demonstrated that CHE induces apoptosis in AGS cells, human stomach adenocarcinoma cell line. One of the most important recent advances in cancer research is the recognition that apoptosis plays a major role in both tumor formation and treatment response, In this study, CHE caused a decrease of viability in AGC cells. When AGS cells were treated with CHE, cells showed dose-dependent manner apoptotic cell death. Increased apoptotic cell death, exposured to CHE, resulted from induction of Bad translocation to mitochondria, cytochrome-c release from mitochondria to cytosol, activation of caspase-3, 8, 9, and PARP cleavage. These results suggest that CHE may be potential therapeutic approach in the clinical management of stomach adenocarcinoma.

  • Squamous cell carcinoma and adenocarcinoma are the major histological types of non-small cell lung cancer. Because they differ on the basis of histopathological and clinical characteristics and their relationship with smoking, their etiologies may be different; for example, different tumor suppressor genes may be related to the genesis of each type. We used microarray data to construct three regulatory networks to identify potential genes related to lung adenocarcinoma and squamous cell carcinoma and investigated the similarity and specificity of them. In the network, some of the observed transcription factors and target genes had been previously proven to be related to lung adenocarcinoma and squamous cell carcinoma. We also found some new transcription factors and target genes related to SCC. The results demonstrated that regulatory network analysis is useful in connection analysis between lung adenocarcinoma and squamous cell carcinoma.

  • A case of primary non-clear-cell adenocarcinoma of the vagina is reported occurring in a 65-year-old woman without exposure to diethylstilbestrol (DES) in utero. The adenocarcinoma did not appear to be associated with vaginal adenosis. It lacked clear cell component and interestingly composed of columnar epithelial cells of endocervical-type. Cytologically round to oval nuclei revealed one or more small nucleoli and fine granular chromatin pattern. Cytoplasm was plump, faintly basophilic and homogeneously stained. Histologically well differentiated columnar epithelial cells were arranged on trabecular pattern mainly, and also occasional glandular lumina and small solid sheets were found. Mitoses were hardly found.

  • Basal cell adenocarcinoma is 1 ~ 2 % of salivary gland carcinoma. It was recently classified as low grade malignancy. It is low grade malignant counterpart of basal cell adenoma. It has similar morphologic attributes with basal cell adenoma, but it has distinctive malignant potential including infiltrative growth into surrounding tissues and distant metastasis. Recently, we have experienced a case of basal cell adenocarcinoma arising from the bilateral parotid gland in a 38-year old woman who was previously operated on superficial parotidectomy due to pleomorphic adenoma. We report this rare case with a review of literature.
