This case describes new onset mammary Paget disease arising in the background of Darier disease. Clinically and histologically, lesions of Darier disease can mask the lesions of mammary Paget disease. A high index of suspicion is necessary to diagnose Paget disease in a patient with Darier disease, for a potentially fatal disease could easily be missed.

A cat was presented with skin lesions consisting of slightly raised pigmented plaques, 2-7 mm in diameter with a rough slightly verrucous surface. Histologically these lesions were identified as papillomas. A papillomavirus infection was demonstrated: virus-like particles were present in the nuclei of cells within the lesions, and staining with an anti-bovine papillomavirus (BPV-1) antibody was...

BACKGROUND Remodeling of the arterial extracellular matrix participates importantly in atherogenesis and plaque complication. Increased expression of the elastinolytic and collagenolytic enzyme cathepsin L (Cat L) in human atherosclerotic lesions suggests its participation in these processes, a hypothesis tested here in mice. METHODS AND RESULTS We generated Cat L and low-density lipoprotein ...

Mammary fat is the main composition of breast, and is the most probable candidate to affect tumor behavior because the fat produces hormones, growth factors and adipokines, a heterogeneous group of signaling molecules. Gene expression profiling and functional characterization of mammary fat in Chinese women has not been reported. Thus, we collected the mammary fat tissues adjacent to breast tum...

coronary artery disease is the leading cause of death worldwide. in this study, we compared two surgical methods of left internal mammary artery (lima) anastomosis on left anterior descending (lad) artery in patients with severe diffuse lesions. a total of 40 patients were included in our study and randomly assigned into two groups. in group a, after a long arteriotomy on lad, the posterior sur...

Ileocolitis associated with spiral bacteria identified as an Anaerobiospirillum sp. was found in six cats. Two cats had acute onset of gastrointestinal signs characterized by vomiting and diarrhea in one cat and vomiting in another cat, one cat had chronic diarrhea that was refractory to medical therapy; one cat had acute onset of anorexia and lethargy, and two cats had clinical signs that were...

BACKGROUND Canine mammary tumors represent the most common neoplasm in female dogs, and the discovery of cancer biomarkers and their translation to clinical relevant assays is a key requirement in the war on cancer. Since the description of the 'Warburg effect', the reprogramming of metabolic pathways is considered a hallmark of pathological changes in cancer cells. In this study, we investigat...

These studies were undertaken to determine if altered growth potential of mammary epithelial cells could be detected in outgrowths derived from monodispersed mammary cells of virgin female BALB/c mice previously exposed to ionizing radiation or 7, 12-dimethylbenz(a)anthracene (DMBA). Monodispersed mammary epithelial cells were obtained by enzymatic dissociation of mammary tissues of 12-week-old...
