......................................... Received: 24/07/13 Accepted: 27/08/13 Abstract We present the case of a 60 year old patient suffering pain and the sensation of a foreign body in the anal region associated with traces of blood in stools. Digital rectal exam (DRE) revealed a hardened lesion located on the wall of the anal canal. Colonoscopy revealed a raised proliferating lesion with a ...
OBJECTIVE To determine the predictive dermoscopic features of amelanotic and hypomelanotic melanoma. DESIGN A total of 105 melanomas (median Breslow thickness, 0.76 mm), 170 benign melanocytic lesions, and 222 nonmelanocytic lesions lacking significant pigment (amelanotic, partially pigmented, and light colored) were imaged using glass-plate dermoscopy devices and scored for 99 dermoscopic fe...
A immber of workers have demonstrated uptake of DNA by mammalian cells (1-6). At least some of the donor DNA appears to be incorporated intact into the nuclei of the host cells (3-6). However, very few investigators have reported genetic transformation of mammalian cells by mammalian DNA (7-9). Two cases which did indicate genetic transformation depended upon measuring the growth of drug-sensit...
This article describes the case of a 62-year-old patient who developed an erosive nodular mass on the nail apparatus after receiving a trauma during a hunting incident. The lesion was initially diagnosed as an amelanotic melanoma of the nail apparatus, illustrating the fact that this type of lesion is often misdiagnosed – up to 85% of the time if the physician lacks dermatological expertise –an...
MATERIALS AND METHODS Murine malignant melanoma (B16) cells tolerant to 10 and 30 pg of BrdU per ml were maintained for more than one year in culture medium lacking the analog. The analog-containing environment was also eliminated by the injection of cells at several subcultures into host animals. Cells withdrawn from BrdU retained the enlarged, flattened, nonpigmented morphology that is charac...
Four months previously, the patient had presented to another clinic with a painless mass in the right parotid region. There was no skin lesion at that time. A fine needle biopsy was performed. The pathology results indicated that the mass was a malignant tumor, and the surgeon suggested total parotidectomy; however, the patient was afraid of surgery and did not seek medical attention again unti...
