A case of biliary adenofibroma of the liver with malignant transformation: a morphomolecular case report and review of the literature.

BACKGROUND: Biliary adenofibroma is an exceptionally rare benign liver tumor with the potential for malignant transformation. In literature, only 21 cases have been described. CLINICAL PRESENTATION: In a healthy 63-year-old woman, a partly solid, partly cystic mass in the left lobe of the liver during a routine ultrasound examination was found. The computed tomography (CT) scan of the abdomen showed a 6.3 × 5.0-cm multilobulated cystic, partly hypervascularized mass in the liver segment IVa, with extension into segments II and IVb. There was no evidence of lymph node or distant metastases. Extirpation of the tumor was indicated by the multidisciplinary tumorboard. Microscopic examination showed a biphasic composed tumor with tubules embedded in fibrous stroma. In addition, there were also areas with pseudopapillary projections, as well as parts with focal cribriform-like growth pattern, which have been indicated as a possible sign of malignant transformation. Additionally, we found two different polymorphisms in the encoded TP53 und KIT in both distinct morphology tumor areas by molecular analysis, which ensured a tumor in malignant transformation. The patient has been alive for 24 months after R0 resection without tumor recurrence. Further investigation of more cases of this rare entity is necessary to proof molecular genesis. CONCLUSIONS: We report a rare case of a biliary adenofibroma with transition to an intrahepatic cholangiocellular carcinoma and present a brief literature review.

Long-term tumor-free survival in a metastatic pancreatic carcinoma patient with FOLFIRINOX/Mitomycin, high-dose, fever inducing Viscum album extracts and subsequent R0 resection: A case report.

RATIONALE: Metastatic pancreatic cancer has a dismal prognosis. Many patients seek integrative care as an add-on to their conventional cancer treatment. Viscum album extracts (VAE)-widely used as an adjunct to cancer treatment-have cytotoxic, apoptogenic, and immune stimulatory properties. A statistically significant survival benefit has been demonstrated for VAE in advanced pancreatic cancer. PATIENT CONCERNS AND DIAGNOSIS: A 28-year old patient presented with painless jaundice and was subsequently diagnosed as pancreatic adenocarcinoma with liver metastases. INTERVENTIONS: He was treated with FOLFIRINOX/Mitomycin, hyperthermia and fever-inducing VAE. OUTCOMES: Subsequently, the liver metastases regressed. Surgical intervention involved successful R0-resection of the primary tumor, as well as an atypical liver resection. A relapse was again treated with FOLFIRINOX/Mitomycin and hyperthermia. As of publication of this report, 49 months after initial diagnosis, the patient exhibits good condition, and is unrestricted in quality of life (till publication). LESSONS: This case demonstrates the favorable outcome of a patient with metastatic pancreatic cancer following treatment with chemotherapy, integrative medicine, and surgical excision. As other positive outcomes in pancreatic cancer patients are related to inflammatory events, we presume the immunologic effects of VAE to have contributed to the favorable outcome here. Based on this case, and the other positive results of VAE use in pancreatic cancer, further investigations seem highly worthwhile.

Primary choriocarcinoma of the liver: a rare, but important differential diagnosis of liver lesions.

The case of a 64-year-old man with spontaneous acute abdominal bleeding is presented. Under suspicion of an atypical hepatocellular carcinoma an extended left hemihepatectomy was performed. Histological diagnosis after surgical therapy revealed a primary hepatic choriocarcinoma. During follow-up within 5 months several metastases were detected. Because of the number and localization of the metastases, there was no further curative surgical option and palliative systemic chemotherapy was initiated. Primary choriocarcinoma of the liver is an important differential-diagnosis in hypervascularized lesions of the liver. This tumor-entity is highly aggressive, with rapid tendency for metastatic spreading. This correlates with the poor prognosis of 12 months after tumor-detection.

Depth-resolved measurement of the dermal matrix composition by multiphoton laser tomography.

BACKGROUND: In the last years, multiphoton laser tomography (MLT) has emerged as a promising tool for non-invasive diagnostics in dermatology and other medical specialties. The present work is dedicated to the question to what degree the measurement depth and the thickness of the epidermis influence the evaluation of dermal matrix composition and if recommendations for future measurement procedures can be given. METHODS: In a study group of 30 healthy volunteers aged 21-82 years multiphoton depth-resolved measurements of autofluorescence and second harmonics have been performed in order to evaluate the dermal matrix composition. RESULTS: Characteristic intensity curves depending on the penetration depth were derived and differences between age groups were found. CONCLUSION: With the present work we provide evidence for the accuracy of the measurement of dermal matrix composition by MLT and give detailed advice for the measurement procedure. Furthermore, we propose the use of depth-dependent emission intensity curves for monitoring of anti-aging treatment.
