1/11. Crusted (Norwegian) scabies in a patient with smoldering adult T-cell leukemia.Crusted (Norwegian) scabies is described in a patient with smoldering adult T-cell leukemia (ATL). The patient is an 84-year-old Japanese woman who presented with widespread scaling over the trunk and limbs and crusted lesions on the scalp and ears. Microscopical examination of scrapings from the scalp and ears showed extraordinarily large numbers of scabies mites. The white blood cell count was 5.1 x 10(9)/L with 6% abnormal lymphocytes with mature nuclei that showed convolution and lobulation. Anti-htlv-i antibodies were positive. Southern blot analysis revealed that the cellular dna extracted from this patient's peripheral blood cells, digested with Pst I, showed the same pattern of provirus genome as the dna from ATL patients. A diagnosis of crusted scabies with smoldering ATL was made. It is possible that crusted scabies could be an opportunistic infection and a pre-diagnostic sign of ATL.- - - - - - - - - - ranking = 1keywords = scalp (Clic here for more details about this article) |
2/11. Epidemic Norwegian scabies.Norwegian scabies is an ectoparasitic infestation by sarcoptes scabiei, characterized by hyperkeratotic lesions of the hands, feet, ears, and scalp, which contain many mites. An epidemic of Norwegian scabies involved 22 patients in a 25-patient ward of mentally and physically handicapped persons (mostly mongoloids). The pathogenesis of the prolific mite population is unclear, but either a specific immunologic deficit or the inability to effectively eliminate the mites by scratching is a plausible possibility.- - - - - - - - - - ranking = 0.5keywords = scalp (Clic here for more details about this article) |
3/11. Epidemic Norwegian scabies in a geriatric unit.Norwegian scabies is highly contagious and presents with a psoriasiform dermatosis. It afflicts particularly the elderly and patients with immunosuppression. Two weeks after the admission of an index case of Norwegian scabies to a geriatric ward, 13 and 25 patients and 6 of 18 ward nurses developed scabies. Despite comprehensive treatment, the ward epidemic recurred 6 weeks later probably as a result of inadequate treatment of the index case. This diagnosis should be considered when patients from high-risk groups present with an undiagnosed rash.- - - - - - - - - - ranking = 0.92918371921475keywords = dermatosis (Clic here for more details about this article) |
4/11. Atypical crusted scabies.Five cases of an atypical form of crusted (or Norwegian) scabies are described. Three cases occurred in patients who suffered from a malignant tumor, and two additional cases occurred in mentally retarded and physically debilitated patients. These cases should draw attention to the possibility of a scabietic infestation whenever a widespread, scaly, itchy dermatosis develops in a debilitated immunosuppressed patient.- - - - - - - - - - ranking = 0.92918371921475keywords = dermatosis (Clic here for more details about this article) |
5/11. Neonatal scabies.scabies contracted during the neonatal period demonstrates a distinct clinical pattern that differs greatly from manifestations seen in older individuals. Involvement of the face, neck, scalp, palms, and soles is a consistent finding, as is the tendency for these lesions to form pustules early in the course of the infestation. Poor feeding and failure to gain weight appropriately are also characteristic features. The skin lesions include erythematous papules, nodular crusts, and putules. The possibility of scabies should be entertained for any young infant who has these findings. Scrapings should be obtained from multiple sites to confirm the diagnosis. In the absence of positive findings for scrapings, examination of close contacts and a careful history should lead to the correct diagnosis.- - - - - - - - - - ranking = 0.5keywords = scalp (Clic here for more details about this article) |
6/11. Crusted scabies in systematic lupus erythematosus: a case report.Crusted scabies (Norwegian scabies) is uncommon in clinical practice and may present as papulosquamous dermatosis. A case of crusted scabies in systemic lupus erythematosus (SLE) is described. The skin lesions simulated those of subacute cutaneous lupus erythematosus of the papulosquamous type, and became the source of epidemic scabies in the hospital. The colonization with staphylococcus aureus within crusted lesions may have contributed to the patient's sepsis. This case illustrates the pitfalls in recognition of crusted scabies and the importance of rapid diagnosis.- - - - - - - - - - ranking = 0.92918371921475keywords = dermatosis (Clic here for more details about this article) |
7/11. Localized bullous scabies. Uncommon presentation of scabies.A previously unreported form of localized bullous scabies mimicking bullous pemphigoid is described. The patient presented with a localized, severely pruritic erythematous plaque with a cutaneous eruption consisting of several papules and a single tense bulla on an erythematous base. The histologic findings consisted of a subepidermal inflammatory bullous dermatosis with lymphocytes, neutrophils, and many eosinophils, and the results of direct immunofluorescence were negative. Correlation of the clinical course with the histologic and immunofluorescence findings were necessary to establish the diagnosis of infestation by sarcoptes scabiei.- - - - - - - - - - ranking = 0.92918371921475keywords = dermatosis (Clic here for more details about this article) |
8/11. scabies of the scalp mimicking seborrheic dermatitis in immunocompromised patients.Two children with acute lymphoblastic leukemia undergoing chemotherapy had a special form of scabies characterized by fine scaling of the scalp simulating seborrheic dermatitis. pruritus was mild or absent. Immunocompromised children and adults should receive whole-body and scalp antiscabietic treatment.- - - - - - - - - - ranking = 3keywords = scalp (Clic here for more details about this article) |
9/11. Crusted scabies associated with systemic lupus erythematosus: response to benzyl benzoate therapy.A 30-year-old Thai woman with systemic lupus erythematosus developed crusting, erythematous scaling plaques on the scalp and neck. Histologic section showed numerous mites in the stratum corneum. The diagnosis was further confirmed by identification of sarcoptes scabiei in scraping and potassium hydroxide preparations made from the cutaneous lesions. After applications of 25 per cent benzyl benzoate for one month, there was complete resolution of the parasitic infestation.- - - - - - - - - - ranking = 0.5keywords = scalp (Clic here for more details about this article) |
10/11. Localized crusted scabies of the scalp and feet.An atypical case of crusted scabies in a patient with acquired immunodeficiency syndrome is presented in which lesions at the time of evaluation were confined to the scalp and feet. Because of the unusual presentation, the scalp involvement (which clinically mimicked seborrheic dermatitis) was initially missed. Although both the crusted variant of scabies and scabietic involvement of the scalp are well documented to occur in immunocompromised patients, to our knowledge scabies confined to the scalp and feet has not been previously reported.- - - - - - - - - - ranking = 4keywords = scalp (Clic here for more details about this article) |
