A 17-year-old neutered male Miniature Pinscher dog presented with a mass on the left side of the submandibular region. Fine needle aspiration revealed malignant epithelial cells from the salivary gland but no evidence of metastasis was found on radiography, ultrasonography, or computed tomography. The cervical mass was surgically resected, and the histopathological examination confirmed adenocarcinoma of the mandibular salivary gland. Seven months after the initial diagnosis, the dog is alive without any clinical signs. This report describes the clinical findings, cytology, diagnostic imaging, and histopathological characteristics of a mandibular salivary gland adenocarcinoma in a Miniature Pinscher dog.

Background: To study the clinical presentation of cervical carcinoma correlating with histopathological findings in a tertiary hospital situated in the southern part of India catering to rural and semi-urban populations Materials and Methods: 199 cases histopathologically diagnosed as cervical cancer over a period of one year were considered for the study. Clinical details of the patients were noted with the help of semi-structured proforma. The data was analysed by descriptive analysis using SPSS software. Results: Out of 199 patients, 109 had moderately differentiated squamous cell carcinoma, 51 poorly differentiated and 35 well differentiated. Adenocarcinomas numbered only four. 121 cases were in the age group of 40-59 years, 59 in 60-80 years and 19 in 20-39 years. All four cases of adenocarcinoma were seen between 40-59 years. 95 (47.7%) cases were in women who had 4 or more children, 120 presented with white discharge, 89 with bleeding per vagina and 68 had constitutional symptoms. Most of the patients with adenocarcinoma presented with bleeding per vagina. 151 was in stage IIIB, 29 in stage IIB, 14 in stage IVA and 5 in stage IB. Conclusions: Screening of cervical cancer should be emphasised in women with white discharge especially in rural areas for early detection of dysplastic cells and reduce mortality and morbidity in productive age. In addition health education has to be given to women regarding the awareness of hygiene, risk factors and symptoms of cervical cancer.

Purpose: Salivary duct carcinoma(SDC) is uncommon but high grade adenocarcinoma arising in the ductal epithelium of salivary glands. SDC is characterized by distinctive clinical and pathologic features. The most important histologic aspect of this neoplasm is its resemblance to ductal carcinoma of the breast. Clinically SDC is defined by cervical lymph node involvement and distant metastasis with a high rate of recurrence and mortality. We described some of the clinical and pathological features of SDC and the management using case report for our patient. Methods: We present a case of a 40-year-old male with 2-year history of a swelling arising in his left preauricular region. There was a single painless, firm and solid $2{\times}1.5cm$ mass in the left parotid area. Facial nerve function was intact and no cervical lymph node were palpable. In August 2005, we found out $1.7{\times}1.8cm$ sized cystic, nodular lesions that were located in the superficial lobe of left parotid gland through Computed tomography. And then superficial parotidectomy and postoperative radiation therapy were performed in Jan 2007. Results: Pathologically, the specimen were consisted of homogeneous, chondoid to myxoid type of tissues. It was yellow mass that has multiloculated cystic lesions. In postoperative PET(Positiron emission tomography) CT, there was no evidence of uptaking FDG(Fluorodeoxyglucose) into the deep layers of parotid gland and distant metastasis were not seen. Conclusion: Salivary duct carcinoma(SDC) is a rare but high grade adenocarcinoma related to pleomorphic adenocarcinoma. The prognosis of SDC can be different according to the type of tumor such as mucoepidermoid adenocarcinoma, adenoid duct carcinoma and acinar cell carcinoma. So we need to study more carefully for accurate diagnosis in early stage of diagnosis. Although radiotherapy has not yet proven to be a significant factor in overall survival, the combination of parotidectomy and postoperative radiation therapy can lead to more favorable results in treating of SDC.

Background: To determine rates of residual disease along with influencing factors in women with stage IA to IB1 cervical carcinoma after conization. Materials and Methods: A retrospective study was conducted of medical records of 198 stage IA to IB1 cervical carcinoma patients who had undergoing cervical conization followed by primary surgical treatment during 2006-2013. Independent factors correlating with residual carcinoma in subsequent surgical specimens were analyzed by stepwise regression analysis. Results: Mean age was 48.9 years. Cone specimens demonstrated free margins in 36 women (18.8%). In case of having disease at margin, high-grade cervical intraepithelial neoplasia (CIN) and carcinoma were evidenced in 58 and 97 women, respectively. Pathology of subsequent specimens revealed residual carcinoma in 78 women (39.4%), high-grade CIN or adenocarcinoma in situ (AIS) in 45 (22.7%), and no residual pathology in 75 (37.9%). Age more than 35 years, postmenopausal status, having symptoms, diseases or invasive lesions at conization margins or disease on endocervical aspect, and higher stage were significantly correlated with residual cancer in surgical treatment specimens. On regression analysis, postmenopause and stage were independent factors associated with residual carcinoma.Conclusions: Patient and tumor characteristics are predictive factors for residual cancer in the studied group of women.

Background: Atypical squamous cells of undetermined significance (ASCUS) feature a wide variety of cervical cells, including benign and malignant examples. The management of ASCUS is complicated. Guidelines for office gynecology in Japan recommend performing a high-risk human papillomavirus (HPV) test as a rule. The guidelines also recommend repeat cervical cytology after 6 and 12 months, or immediate colposcopy. The purpose of this study was to determine the clinical significance of ASCUS. Materials and Methods: Between January 2012 and December 2014, a total of 162 patients underwent cervical conization for cervical intraepithelial neoplasia grade 3 (CIN3), carcinoma in situ, squamous cell carcinoma, microinvasive squamous cell carcinoma, and adenocarcinoma in situ at our hospital. The results of cervical cytology prior to conization, the pathology after conization, and high-risk HPV testing were obtained from clinical records and analyzed retrospectively. Results: Based on cervical cytology, 31 (19.1%) of 162 patients were primarily diagnosed with ASCUS. Among these, 25 (80.6%) were positive for high-risk HPV, and the test results of the remaining 6 patients (19.4%) were uncertain. In the final pathological diagnosis after conization, 27 (87.1%) and 4 patients (12.9%) were diagnosed with CIN3 and carcinoma in situ, respectively. Conclusions: Although ASCUS is known as a low-risk abnormal cervical cytology, approximately 20% of patients who underwent cervical conization had ASCUS. The relationship between the cervical cytology of ASCUS and the final pathological results for CIN3 or invasive carcinoma should be investigated statistically. In cases of ASCUS, we recommend HPV tests or colposcopic examination rather than cytological follow-up, because of the risk of missing CIN3 or more advanced disease.

The development of skin metastasis is usually a morbid prognostic feature although they occur infrequently. Adenocarcinomas account for up to about 70% of all metastatic skin cancer. In general, adenocarcinomas are the most difficult metastatic tumor to accurately identify the primary site because they don't have distinctive histological features. For this reason, immunohistochemistry have been used to help identify the origin of metastatic adenocarcinomas. This study performed immunohistochemical staining with metastatic adenocarcinomas of the skin using a variety of antisera to find out characteristic immunohistochemical findings of them. This study was made upon the 29 cases of metastatic adenocarcinomas of the skin, which had been confirmed histopathologically in Chonbuk National University Hospital from January, 1986 to April, 2006, Paraffin blocks were colledted and homemade tissue arrays were made. We performed immunohistochemical staning using 12 antibodies (MUC1, 2, 5AC, 6, cytokeratin (CK) 7, 20, thyroid transcription factor-1 (TTF-1), estrogen receptor (ER), progesterone receptor (PR), beta-catenin, cox-2, claudin-1). The mean age at the time of diagnosis was 60.7 years and the male to female ratio was 1.2:1.0. The most common primary site was lung, followed by stomach and colorectum. MUC1 was expressed by most colorectal, breast and lung adenocarcinoma. MUC2 was expressed infrequently. MUCSAC was expressed by most gastric and colorectal cancer MUC6 was not specific of any primary site in this series. CK7+/CK20+immunophenotype was observed in gastric, lung, colorectal adenocarcinoma. CK7+/CK20- immunophenotype was observed in breast, lung, endometrial, uterine cervical, bile duct adenocarcinoma, while CK7-/CK20+ immunophenotype was observed only in colorectal adenocarcinoma. This results show the utility of TTF-1 to confirm the pulmonary origin. On the other hand ER and PR were not useful markers to assess the origin of primary tumor in this series.

This study was conducted to determine whether advancing age is an independent predictor of increased risk of high-grade pathologies among women referred for colposcopy after abnormal cervical cytology. Medical records were reviewed for women with abnormal cervical cytology who underwent colposcopy at Khon Kaen University Hospital. Logistic regression was used to determine the independent impact of age on the risk of high-grade pathologies. Mean age of the women was 42.8 years. Of 482 women, 97 (20.1%) were postmenopausal, and 92 (19.1%) were nulliparous. The rate of high-grade pathologies included cervical intraepithelial neoplasia 2-3, 99 (20.5%), adenocarcinoma in situ, 4 (0.8%), cervical cancer, 30 (6.2%), and endometrial cancer, 1 (0.2%). The prevalence of significant lesions was 26.9% (95% CI, 23.1%-31.2%). In total, 31 women had cancers (6.4%; 95% CI, 4.4%-9.0%). When controlling for smear types and parity, age was noted to be a significant independent predictor of high-grade histopathology. Women older than 35-40 years were approximately 2 times as likely to have severe histopathology as the younger women. This study illustrates the substantial risk of underlying significant lesions especially invasive cancer in Thai women with abnormal cervical cytology. Age was a significant independent factor predicting the risk of high-grade pathologies.
