The synergetic effect of estrogens and androgens is known to play a crucial role in the physiopathology of the prostate gland. Bisphenol A (BPA) is an endocrine disrupting compound that can interfere with endocrine hormone functioning and thereby influence prostate development. The objective of this study was to examine the impact on prostate expression of aromatase, 5α-R isozymes, and prostate cancer-related genes of exposure to low doses of BPA from perinatal period to adulthood. Vehicle or BPA (2.5 μg/kg b.w./day) was administered to gestating Wistar rats from gestational day 12 (GD12) to parturition and then to their male pups from postnatal day 1 (PND1) until euthanization on PND90. Their prostate glands were examined by qRT-PCR, Western blot, PCR array, and morphological study. mRNA and protein levels of 5α-R2 were significantly reduced and mRNA and protein levels of aromatase were significantly increased in BPA-treated animals, which also showed modifications of 8 out of the 84 key genes implicated in the development of prostate cancer. Because BPA interferes with genes involved in intraprostatic androgen and estrogen production and others implicated in prostate cancer, research is warranted into the prostate disease risk associated with chronic low-dose BPA exposure throughout life.
Mesenteric inflammatory venoocclusive disease is an uncommon cause of intestinal ischemia. Certain diseases, such as hypercoagulation disorders, autoimmune diseases, or drugs have been associated with the pathogenesis of mesenteric inflammatory venoocclusive disease. Here, we report a patient with Sjögren’s syndrome who underwent surgery for suspected acute appendicitis with a subsequent pathological diagnosis of mesenteric inflammatory venoocclusive disease.
Hand metastasis represents between 0.007 and 0.2 % of all metastatic lesions [1, 2]. Renal cell carcinoma accounts for only 10–12 % [3, 4] of these infrequent lesions. Finger metastases are commonly misdiagnosed due to their low frequency and because they can resemble an infectious condition [5]. We report a case of renal clear cell carcinoma with distal phalangeal metastasis and review the related literature. This case highlights the need to consider acrometastasis in the differential diagnosis of digital lesions in patients with renal clear cell carcinoma. A 53-year-old right-handed man was seen by his family physician for pain and swelling in right fifth finger after a minor trauma; he had a history of disseminated renal clear cell carcinoma (RCC) with radiation-resistant metastases in lung and fourth lumbar and was under combined treatment with sunitinib and everolimus. The initial diagnosis was an infection, which was unsuccessfully treated with NSAIDs, cloxa ...
Objective: We present a case of eosinophilic pustular folliculitis, a rare dermatosis which is often associated with HIV infection or internal malignancies. Clinical Presentation and Intervention: We report the case of a 66-year-old man with a medical history of hypertension. Histopathological examination showed a dense follicular inflammatory infiltrate with abundant eosinophils. The clinical response to indomethacin was excellent with no recurrence during the follow-up. Conclusion: The patient responded well to indomethacin treatment.

Sarcoidosis is a systemic granulomatous disease with an uncertain etiology, characterized by the production of non-necrotizing granulomas. The most frequent presentation is pulmonary and mediastinal, although it might affect any other organ. Hepatic alterations occur in 50 to 65% of the cases. Nevertheless, it is commonly subclinical or detected during a study of the alteration of liver enzymes. It is very unusual that disease onset occurs as an isolated hepatic tumor. A hepatic biopsy is usually required to confirm the diagnosis. A differential diagnosis must be established via any hepatic granulomatous disease, infectious or autoimmune disease as well as the exclusion of malignancy. We present a clinical case of a female diagnosed with an isolated hepatic sarcoidosis that simulated a unique hepatic metastatic lesion.The hepatic biopsy was diagnostic.
