Introduction Carcinomas of the papilla of Vater make up a heterogeneous group of tumours arising from different types of epithelium. Regional lymph nodes, liver and lungs are the primary sites of metastatic progression of these tumours. Case presentation We present a patient with an abdominal incision site metastasis of low-grade (mixed type) adenocarcinoma of the papilla of Vater one year after pylorus-preserving pancreaticoduodenectomy. Implantation metastasis of low-grade ampullary carcinoma in the laparotomy wound after open Whipple’s procedure is unusual. Conclusion Adjuvant chemoradiation might be considered for patients with low-grade localised disease as a potentially preventative measure vs. metastatic progression.

Thirty tumors including 27 distinctive cutaneous neoplasms and 3 metastatic tumors from 26 dogs were collected from diagnostic submissions to 3 laboratories. Characteristic histopathologic features included location in the subcutis or dermis (or both); lobular, nodular, and nest-like architecture; and a component of epithelioid cells with clear cytoplasm. Additional features present in most cases included follicular dermal papilla-like structures, low mitotic index, nuclear pleomorphism, necrosis, and mineralization. Cytoplasmic periodic acid Schiff—positivity, which was abolished by pretreatment with diastase, indicated the presence of glycogen in all cases. The oil red O stain did not demonstrate cytoplasmic lipid. Melanin granules, accentuated by the Fontana-Masson method, were observed infrequently. A sparsely cellular mucinous stroma and stromal cartilaginous differentiation were uncommon. By immunohistochemistry, neoplastic cells stained positively for cytokeratin (29 of 29), vimentin (28 of 28), S-100 protein (24 of 29), and melan A (8 of 12); results were negative for smooth muscle actin and calponin in all cases. Clinical follow-up information was obtained on all 26 dogs. One tumor recurred, 1 metastasized to a regional lymph node, and 1 metastasized to regional lymph nodes twice. In another case, possible pulmonary metastasis was noted radiographically. The findings are consistent with a poorly differentiated, low-grade, adnexal carcinoma of the skin. Similar canine cutaneous neoplasms have been reported as “clear-cell hidradenocarcinoma” and “follicular stem cell carcinoma.” The authors propose the designation “cutaneous clear cell adnexal carcinoma.”

Introduction: PBL is a rare form of extranodal lymphoma. The most common pathology is diffuse large B cell lymphoma and most patients are diagnosed at stages 1 and 2. The therapeutic options undertaken so far include surgery, radiotherapy, and chemotherapy Case Presentation: The patient was a 54-year old woman with localized primary breast DLBCL. The patient underwent 6 courses of chemotherapy with an RCHOP regimen followed by radiotherapy of the breast and regional lymph nodes with a 40 Gy dose. The patient was in complete remission on PET scan 3 months later. Around one year after, the patient experienced relapse in the contralateral breast. Conclusions: In the pattern of relapse of patients, there is a tendency for extranodal relapse. In some studies maximum level of relapse occurring in CNS and some advocate CNS prophylaxis in these patients. The best outcome is for patients treated with chemotherapy including rituximab followed by radiation. We reviewed some studies in the aspect of treatment modalities and site of relapsed.

Abstract Context.—Alterations in molecular elements derived from the CXC chemokine receptor 4 (CXCR4)/stromal-derived factor 1 (SDF-1) cytokine system have been found to strongly correlate with neoplastic progression leading to metastasis in a number of tumors, including osteosarcoma. Excluding hematologic malignancies, chondrosarcoma of bone is the most common primary malignant tumor of bone in adults in the United States. Like osteosarcoma, chondrosarcoma preferentially metastasizes to lung, bone, and very rarely to regional lymph nodes. However, the role of the signal pathway(s) driving neoplastic progression in chondrosarcoma has not yet been clearly elucidated. Objective.—To test whether CXCR4 was detectable in chondrosarcoma and whether CXCR4 expression levels correlated with chondrosarcoma grade. Design.—Twenty-two chondrosarcoma samples banked at our institution between 2001 and 2006 were retrieved for study. By using invasive ductal carcinoma of the breast and osteosarcoma as the positive controls, immunohistochemistry was performed on paraffin-embedded tissue sections and the intensity of the tumor cells was analyzed by morphometric techniques. Results.—All chondrosarcoma cases (22 of 22) were immunoreactive for CXCR4. However, the staining intensity of the CXCR4 between the low- and high-grade groups was significantly different. There was a higher staining intensity in high-grade chondrosarcoma cells (P < .001). Conclusion.—CXCR4 is expressed in chondrosarcomas. CXCR4 expression levels were higher in high-grade chondrosarcoma cells than in low-grade specimens. A larger number of cases will be required to confirm these results and expand the observation, but preliminary data would argue for CXCR4 immunohistochemistry as a potential marker for biologic aggressiveness in chondrosarcoma of bone.

Cryopreservation of male germ cells is a strategy to conserve animal species and strains of animals valuable to biomedical research. However, to minimize damage that may occur during freezing and thawing, complex cryopreservation protocols that have been optimized for the stage and species of male germ cells are usually employed. Recently, we have found that mouse male germ cells can be cryopreserved at -80�C by freezing the whole epididymides and testes without cryoprotectant for at least one year (Ogonuki et al. 2006 Reprod. Fertil. Dev. 18, 286 abst). This study was undertaken to determine whether mouse male germ cells retrieved from the bodies of mice frozen at -20�C for 15 years could produce normal offspring by microinsemination. Mature males of BALB/c-nude and C3H/He (8 weeks of age) were euthanized by overdose of pentobarbital on February 20 and March 8, 1991, respectively, and kept in a -20�C freezer. The frozen body was thawed about 15 years after freezing (February 2006) by putting it in a water bath until the outer surface of the body was softened. The body was then removed from the water, and the testes were isolated through an abdominal incision. Testicular spermatozoa were collected from the testes and microinseminated into B6D2F1 oocytes. Within 24 h after sperm injection, over 80% of oocytes developed into 2-cell embryos. Apparently normal pups were born after embryo transfer in both strains of mice at rates of 21% (17/81) and 12% (12/97) per transfer, respectively. Two pups from the BALB/c-nude group died shortly after Caesarian section due to respiratory failure, but others grew normally and were proven to be fertile when they matured (at least 19 mice out of 20 mice tested). We further mated these F1 offspring and confirmed that the nude gene was safely propagated. The present study demonstrates that spermatozoa can retain their fertilizing ability in frozen whole bodies for longer than we anticipated. If spermatozoa of extinct mammalian species (e.g. woolly mammoth) can be retrieved from animal bodies that were kept frozen in permanent frost, live animals might be restored by injecting them into oocytes from females of closely related species.

Case Presentation. Mrs. X, 35 years old, case of primary infertility, was diagnosed to have genital tuberculosis on the basis of PCR positive and hysterolaparoscopy findings and received category I ATT for 6 months. Following ATT completion, her USG revealed no evidence of tuboovarian mass or hydrosalpinx. Since her tubes were patent, she underwent 3 cycles of ovulation induction and 2 cycles of IUI. The women presented with acute PID, five days after IUI, and was conservatively managed. She again presented 24 days after IUI with persistent low grade fever and abdominal pain. Suspecting relapse of genital tuberculosis, she was started on category II ATT. She had acute episodes of high grade fever with chills 2 weeks after starting ATT and MRI revealed bilateral TO masses suggestive of pyosalpinx. Emergency laparotomy was done, pus was drained, and cyst wall was removed and HPE was suggestive of chronic inflammation with few granulation tissues. ATT was continued for one year and the woman improved.Conclusion. The possibility of flare-up of PID (pelvic inflammatory disease) in treated case of tuberculosis undergoing infertility management should be kept in mind and aggressive management should be done.

Black Schist

Black schist ores in Finland are often enriched with sulfide minerals, containing a variety of base metals such as nickel, copper, zinc and cobalt. As these ores are low grade with respect to the metals contained and the sulfide minerals cannot be effectively concentrated from the schists, they are currently being studied with regard to their suitability for bioleaching [1]. As part of this investigation, a large-scale column measuring 3 x 3 x 9 m was built and filled with 110 tons of the crushed black schist ore. A solution was circulated in the column for 95 weeks; this solution was adjusted to 1.8 prior to entry in the column and averaged 2.7 when leaving the column. During this time, approximately 22% of Mn, 10% of Ni and 5% of Zn were leached from the ore. Iron was also leached, but precipitated in the column. Any soluble iron in the effluent was mainly Fe (II). During this same time period, total cell counts averaged 3.6 x 107 cells/ml of effluent. On three different occasions over nearly a one-year period, culturable cells were enumerated on a variety of solid media [2] and represented only about 1% of the total cell counts. Of the culturable cells, ironoxidizing acidophiles (namely Acidithiobacillus ferrooxidans) far outnumbered any other acidophile by at least a factor of ten. Changes in populations were also monitored by molecular means (T-RFLP and SSCP) on five different occasions during the same year; again, populations in early samples were dominated by Acidithiobacillus ferrooxidans (at least two strains/sub-species). As the temperature of the column was increased from ~20 to 35°C by heating both the recirculated liquor and the air used for column aeration, the relative abundance of At. ferrooxidans-like bacteria decreased while the abundance of unidentified bacteria increased. Some of these bacteria have also been detected in lab-scale column experiments using the same ore [3]. Total cell counts varied little as the temperature increased, nor was there any change in the rate of metal leaching. It was apparent that even though the leaching of metals from black schist ores was not greatly influenced by increases of temperature in the column, active microbial populations were present and were influenced by temperature.

Pseudomyxoma peritonei (PMP) is a rare disease usually originating from appendiceal neoplasm and its incidence is 1-2 cases per million. Extra-appendicular origin is less common and is related to ovary, urachus, stomach, colon and pancreas cancer. A few cases of mature ovarian teratoma associated with PMP have been described. We report an extremely rare case of a man treated for a mature teratoma recurrence as a PMP. A 57-year-old man with multiple surgeries for mature teratoma excision as a newborn was addressed to our institution. At the age of 55, a surgical exploration found a low-grade PMP. The patient was asymptomatic, and surveillance was performed. Nine months later, a sub-complete cytoreductive surgery (CRS) with Mitomycin C HIPEC (hyperthermic intraperitoneal chemotherapy) was performed. One year later, the residual mass volume was treated by a new CRS with Mitomycin C HIPEC. After a two-year follow-up patient has no recurrence. PMP extra-appendiceal origin in less than 10%. This is the first reported case of PMP originating as a mature teratoma recurrence in a man. A few cases describe PMP from ovarian teratoma in women. Despite PMP’s different origins, gold standard treatment still remains CRS and HIPEC.

Mucosa-associated lymphoid tissue-derived lymphoma (MALT lymphoma) arises not only from the stomach but also from various non-gastrointestinal sites. A thirty two year old woman, suffering from breathlessness for one year, had been treated for bronchial asthma. A chest radiograph showed a mediastinum and heart transposition to the right side and emphysema of the left lung. In the thorax spiral tomography, a mass narrowing left main bronchi, five centimeters in length from the carina, was seen. A fiberoptic bronchoscopy revealed millimetric polypoid lesions those nearly totally obstructed the left main bronchi. The bronchoscopic biopsy showed a diagnosis of MALT lymphoma. She was seen for check-ups following chemotherapy but no further treatment has been carried out.

Abstract BACKGROUND Postoperative neurological deficits may outweigh the benefit conferred by maximal resection of gliomas. We evaluated the incidence of ischemic events in patients undergoing surgery for low-grade gliomas (LGG) and the long-term neurological and cognitive sequelae. METHODS Between 2013–2017, 168 patients underwent surgical resection or biopsy for LGG at our center. A full dataset, including pre- and postoperative magnetic resonance imaging (MRI) and long-term clinical evaluation findings, was available for 82 patients (study group). Ischemic complications, overall and progression-free survival, and functional and neurocognitive outcomes were evaluated. RESULTS The immediate postoperative MRI revealed an acute ischemic stroke adjacent to the tumor resection cavity in 19 patients (23%), 13 of whom developed new neurological deficits due to the ischemic event. Infarcts were more common in patients with recurrent tumors, especially those involving the Sylvian fissure (p< 0.05). Surgery for insular gliomas had the strongest association with postoperative infarcts. Survival of patients w/wo a postoperative infarct was the same. The median Karnofsky-Performance Status was lower for the infarct group vs. the non-infarct group at 3 months post-surgery (p=0.016), with a gradual significant improvement for the former over one year (p=0.04). Immediately after surgery, 27% of the patients without infarcts and 58% of those with infarcts experienced a new motor deficit (p=0.037), decreasing to 16% (p=0.028) and 37% (p=0.001), respectively, at one year. Neurocognitive analysis findings before and 3 months after surgery were unchanged, but patients with an infarct had a significant decrease in naming (p=0.04). Confusion during awake craniotomy was a strong predictor of an ischemic stroke. CONCLUSIONS Intraoperative strokes are more prevalent among patients who undergo recurrent surgeries, especially in the insula. Although they do not affect survival, these strokes negatively impact the patients’ activity and performance status, especially during the first 3 postoperative months, with gradual functional improvement over one year.
