Aggregates of melanocytes within the parenchyma of a supraomohyoid lymph node were found in a lymph node dissection from a 52-year-old woman who had a primary cutaneous melanoma that had arisen in association with a small congenital nevus. The melanocytes in the lymph node were interpreted to be those of a benign melanocytic nevus, and not those of malignant melanoma, based on similarities in morphologic features and immunohistochemical staining between the melanocytes in the node and those in the cutaneous congenital nevus. 相似文献

In order to provide a new reference point in the dermatological literature from which the naming of florists' chrysanthemums may be regularised and standardised, the case is presented for the use of the generic name Dendranthema together with a cultivar name in place of a specific epithet. A review of cultivar specificity in chrysanthemum dermatitis is also presented. 相似文献

Eyebrow threading is a practice of shaping the eyebrows. Many dermatological complications have been briefly mentioned in various publications. There are scant data regarding the appearance of molluscum in the line of eyebrows after a session of threading. We report a series of eight patients both males (3) and females (5) who had lesions of molluscum in the eyebrow region after threading. The earlier reported cases are only among the females. The present study is highlighting the appearance of molluscum in the region of eyebrow after a session of threading from beauty salon. So, to the best of our knowledge, this is the first report of its kind describing same pathology in males. The rational of reporting this case series is to create awareness among the dermatologists as well as in general population about potential hazards of threading. 相似文献

Hydrophilic polymer coatings were designed to reduce friction between the catheter and vessel wall and facilitate intravascular manipulations during catheterization and placement of drug‐eluting stents. One newly reported complication of such hydrophilic coatings is the fragmentation and embolization of the polymer, which can lead to ischemia and infarct by blocking the small vasculature. In this report, we present a patient with a non‐healing ulcer on the leg. Biopsy from the ulcer revealed the presence of hydrophilic polymer emboli within the dermal vessels. This is one of the few reports of such a complication involving the skin. Our objective is to emphasize the histopathologic features of this uncommon iatrogenic phenomenon. 相似文献

Paraneoplastic pemphigus in a patient with a thymoma 总被引:3,自引:0,他引:3
A 76-year-old woman, with a history of thymoma, presented with a painful extensive stomatitis, painful paronychia, lichenoid papules on the hands and superficial erosions on the neck and the trunk. Histological examination showed lichenoid changes, acantholytic blister formation and apoptotic keratinocytes. Direct immunofluorescence was positive for IgG both in the epidermal intercellular spaces and along the basement membrane zone. Indirect immunofluorescence was similarly positive in a pemphigus vulgaris pattern. There was only a partial response to intravenous corticoids. These findings allowed the diagnosis of paraneoplastic pemphigus. The diagnostic characteristics, histopathology and the differential diagnosis of this disease are discussed. 相似文献
