1/19. Vegetating iododerma with fatal outcome.A 65-year-old woman on whom a cardiac catherization using iodine contrast had been performed developed 5 days later acute renal failure, respiratory insufficiency and cutaneous lesions consisting of two great vegetating masses located on both cheeks and pustular vesicular lesions on the extremities. A fortnight later, the patient died. We would like to stress this case because of the exceptional nature of vegetating iododerma at present, and the importance of recognizing a possibly fatal disease.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/19. Severe cutaneous reaction to CS gas.Tear gas is used throughout the World for control of riots and civil disobedience. CS gas as used by the UK police force is issued as a 'spray' and is 5% CS in methylisobutylketone (MIBK), a potent irritant. Assaults on police officers in forces issued with CS spray have fallen significantly over the past 3 years, whilst having risen in areas without it. Thus, CS gas appears to be an effective deterrent. However, significant cutaneous reactions can occur as a result of exposure. We report a severe contact dermatitis to CS gas to highlight the clinical features. The nature of CS gas and potential cutaneous adverse reactions are discussed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/19. Necrotizing infundibular crystalline folliculitis.We describe a 22-year-old woman with a background of acne who developed multiple folliculocentric facial papules associated with sharply demarcated waxy, keratotic plugs. Multiple skin biopsies showed umbilicated craters that were filled with dispersed bundles of eosinophilic filaments embedded in a pale amorphous matrix forming a plug. The plugs bulged into the upper dermis. Serial sections showed vacuolar and filamentous destruction of the infundibular and adjacent perifollicular epithelium and a close relationship of the crystalline necrosis to follicles. Electron microscopy revealed that the filamentous bundles were tonofilaments. No fresh material was available for polarization and the paraffin sections failed to polarize. The clinical and pathological findings of the lesions in our patient were identical to those reported as a new perforating disorder with urate-like crystals. Our case indicates that the process may represent crystalline folliculocentric necrosis rather than a primary perforating disorder. The nature and basis of the crystals that have a urate-like appearance remain to be determined.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/19. Facial porokeratosis characterized by destructive lesions.porokeratosis is a rare group of keratinizing diseases. It is inherited as an autosomal dominant disease with variable penetrance, although sporadic cases are often reported. porokeratosis has as its histological hallmark the typical cornoid lamella. porokeratosis lesions localized on the face can vary from superficial to destructive in nature. Only 12 cases have been reported in the literature to date. We report one more unusual case of destructive facial porokeratosis.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/19. lupus vulgaris--report of a case with facial involvement.Cutaneous tuberculosis of the orofacial region is a rare condition and when it occurs, can cause confusion regarding the true nature of the lesion. This is compounded by the fact that neither mantoux test nor histopathology is confirmatory. In this report we discuss a case of lupus vulgaris with emphasis on the diagnostic approach to be followed by dental practitioners who come across a similar case.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/19. Folliculosebaceous cystic hamartoma arising within a port-wine stain.A 34-year-old woman presented with 2-year history of a dome-shaped papule on a well-circumscribed, thickened, port-wine stain on the left side of the chin. Squeezing on the port-wine-stain plaque revealed many comedos within dilated follicular orifices. The papule was excised and submitted for histological examination. Histopathological study showed a lobular neoplasm, comprising dilated, cystic pilosebaceous structures surrounded by fibrous stroma, bearing the characteristics of folliculosebaceous cystic hamartoma. The reported case shows that, in addition to the vascular nature, both ectodermal and mesenchymal abnormalities may be involved in port-wine stains.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/19. Excision of subcutaneous facial cysts and lipomas using cosmetic approaches.PURPOSE: The excisional biopsy of subcutaneoous facial cysts and lipomas can be problematic due to the high esthetic nature of the affected area. Remote scar placement has advantages in allowing access to subcutaneous pathology while placing incision lines in cosmetic locations. This article will review excisional biopsies of subcutaneous facial cysts and lipomas using cosmetic approaches. patients AND methods: patients with superficial facial cysts or lipomas undergoing excisional biopsies utilizing contemporary cosmetic surgery approaches (rhytidectomy, lower blepharoplasty, and submental) with tumescent anesthesia and either intravenous sedation or general anesthesia. RESULTS: All patients had successful removal of superficial facial pathology with good cosmetic results. CONCLUSION: The use of contemporary cosmetic surgical approaches for the excisional biopsy of superficial facial cysts and lipomas provides adequate surgical access, a cosmetically acceptable result, and is well-tolerated by patients.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
8/19. face--facial Afro-Caribbean childhood eruption.Five cases of a distinctive facial eruption in Afro-Caribbean children are described. Distinctive features include monomorphic papules that are confined to the face, especially around the mouth, eyelids and ears, its greater prevalence in black children, and its tendency to persist for several months before spontaneous resolution. The aetiology of this condition is unknown and its importance lies in reassuring patients of the benign and purely cutaneous nature of the eruption.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
9/19. Malignant melanoma simulating schwannian differentiation.A malignant melanoma demonstrating palisades of spindled melanocytes strikingly similar to Verocay bodies is reported. Immunohistochemical staining for S-100 protein and neuron-specific enolase revealed uniform positive staining of the neoplastic cells consistent with malignant melanoma. Immunohistochemical staining for myelin basic protein, a marker specific for schwann cells, was negative in neoplastic cells. Ultrastructural examination revealed numerous melanosomes, confirming the melanocytic nature of this neoplasm. The differential diagnosis and possible histogenesis of this neoplasm are discussed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
10/19. Atopic cataract induced by severe allergic contact dermatitis on the face.Although atopic cataracts commonly occur in adolescent and young adult patients with severe atopic dermatitis, we observed a 34-year-old woman with mild atopic dermatitis who abruptly developed atopic cataracts in both eyes when she suffered from severe allergic contact dermatitis on the face. This case seems to suggest that prompt control of severe dermatitis on the face in patients with atopic dermatitis is important for prevention of atopic cataract, whether the dermatitis on the face is atopic or nonatopic in nature.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
