摘要:

ABSTRACTFive patients developed pruritic, keratotic, perforating follicular papules and nodules within 2 months of starting maintenance hemodialysis. Clinically and histologically, the papules and nodules showed the features of perforating folliculitis with superimposed prurigo nodularis, a condition not previously described in patients on maintenance dialysis. The patients with perforating folliculitis constituted 10% of our patients on dialysis during the period of this study. Notably, all five patients were black and had chronic renal failure secondary to diabetic nephropathy. The precise pathogenesis of perforating folliculitis in these patients is unclear at this time.

摘要:

ABSTRACTThree patients developed perforating skin lesions on the legs shortly after beginning hemodialysis for chronic renal failure. All had long-standing insulin-dependent diabetes mellitus and all three were white. The skin disease was refractory to all attempts at management. In one patient, however, the eruption cleared completely when hemodialysis was stopped in favor of a renal allograft transplanted from a cadaver. Clinically and histologically, some of the lesions showed evidence of prurigo nodularis, a consequence of vigorous rubbing of a discrete focus.

摘要:

ABSTRACTThe term epidermal collarette has been used to describe the infoldings of epithelium frequently seen around or embracing pyogenic granulomas and verrucae. In this paper, collarettes are demonstrated in a variety of lesions, and are shown to be formed by epithelial adnexa and not of the epidermis. A theory about the collarette as a formation of adnexal epithelium is proposed.

摘要:

ABSTRACTBefore stains were available, pathologists had to rely on unstained sections viewed through crude microscopes, but they still were able to make diagnoses and discoveries. Unstained sections may still be used to advantage in making diagnoses of skin lesions quickly, accurately, and easily on the basis of negative image patterns. Low-power scanning by conventional microscopy of freshly cut and mounted, still wet, paraffin sections of skin specimens enables the histotechnologist and derma-topathologist to accomplish three things: 1) to check orientation of the sections at an early stage, 2) to cut complete sections, and 3) to find the area or areas of pathology to cut. Furthermore, because diagnoses can be made from unstained sections, extra cuts for special stains may be ordered in advance of routine staining. The dermato-pathology laboratory is able, therefore, to produce slides of better quality and diagnoses more accurately and quickly.

摘要:

ABSTRACTAn immunofluorescent serological finding, the “string of pearls” effect, was seen in 61 patients who were taking a variety of drugs. In the majority of these patients, this sign was thought to represent an adverse response to a drug. Its detection may be helpful in monitoring the ill effect of drugs.
