1/32. larva migrans within scalp sebaceous gland.A case of larva migrans or serpiginous linear dermatitis on the scalp of a teenager is reported. An ancylostomid larva was found within a sebaceous gland acinus. The unusual skin site for larva migrans as well as the penetration through the sebaceous gland are highlighted. The probable mechanism by which the parasite reached the skin adnexa is discussed.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
2/32. Allergic contact dermatitis caused by dialkyl thioureas in a patient with sleep apnea.Allergic contact dermatitis of the scalp is relatively uncommon. This is a case report of a patient with chronic scalp dermatitis in the distribution of his continuous positive airway pressure (CPAP) mask neoprene rubber strap. Our objective was to identify any relevant contact allergens. Patch testing to the North American Contact dermatitis Group (NACDG) Standard allergens, a series of supplemental rubber allergens, and a sample of the neoprene from the patient's mask strap was performed. Relevant allergies to dialkyl thioureas, and the neoprene rubber portion of the CPAP mask strap were identified. Replacement with a cloth strap resulted in clearing of the dermatitis.- - - - - - - - - - ranking = 7.0565091991065keywords = dermatitis, contact (Clic here for more details about this article) |
3/32. Severe dermographism after topical therapy with diphenylcyclopropenone for alopecia universalis.We describe here a 19-year-old Japanese man with an 11-year history of alopecia universalis, who, after the 1st application of a 0.003% diphenylcyclopropenone (DPCP) solution to the whole scalp, developed acute contact dermatitis at the test site, together with widespread severe dermographism. Every 3 weeks, persistence of the severe urticarial reaction and efficacy of treatment were monitored by constant pressure stimuli in a series of pressure tests, and subsequently evaluated by laser Doppler flowmetry (LDF). Although, on pressure tests, the urticarial response was found to significantly improve after starting treatment, erythematous responses continued to appear for nearly 3 months. The persistent course of these side-effects in our patient strongly suggests that precautions must currently be taken in the therapeutic use of potent sensitizers such as DPCP.- - - - - - - - - - ranking = 1.0094181998511keywords = dermatitis, contact (Clic here for more details about this article) |
4/32. Four cases of sebopsoriasis or seborrheic dermatitis of the face and scalp successfully treated with 1a-24 (R)-dihydroxycholecalciferol (tacalcitol) cream.A 71-year-old woman visited our clinic due to the presence of widespread scaly erythema on her face, scalp, and lower extremities. She was tentatively diagnosed as having seborrheic dermatitis but the symptoms were difficult to distinguish from psoriasis vulgaris. As a result, she was diagnosed as having sebopsoriasis. She was treated topically with an active vitamin D3 compound, 1a-24 (R)-dihydroxycholecalciferol D3 (tacalcitol) cream. She applied tacalcitol cream twice daily for 4 weeks, and her facial eruptions thus cleared up completely. No recurrence was observed for 2 months thereafter, even though the use of tacalcitol cream was stopped. To investigate whether or not tacalcitol cream is generally effective for the treatment of such seborrheic dermatitis-like eruptions, three more patients were treated with tacalcitol cream. All patients exhibited scaly erythematous macules on the face and/or scalp, and their eruptions improved rapidly with tacalcitol cream. Tacalcitol cream was thus found to be effective and useful for the treatment of both sebopsoriasis and even seborrheic dermatitis of the face and scalp.- - - - - - - - - - ranking = 7keywords = dermatitis (Clic here for more details about this article) |
5/32. Telogen effluvium after allergic contact dermatitis of the scalp.OBJECTIVE: After observing 2 cases of acute telogen effluvium induced by allergic contact dermatitis to hair dyes, we decided to evaluate the effects of acute contact dermatitis of the scalp on the hair cycle. DESIGN: Single-center, 6-month study of consecutive patients affected by acute scalp dermatitis. SETTING: Department of dermatology, University of Bologna, Bologna, italy. patients: diagnosis of allergic contact dermatitis of the scalp was confirmed by patch testing. Eight women presenting with acute contact dermatitis of the scalp entered the study. Hair shedding was evaluated monthly for 6 months by pull test and wash test. Increased hair loss was detected in 4 of the 7 patients who completed the study. Hair loss was mild to moderate and appeared 2 to 4 months after the episode of scalp dermatitis. A scalp biopsy specimen from 2 patients confirmed the diagnosis of telogen effluvium. CONCLUSIONS: Allergic contact dermatitis of the scalp should be included among the possible causes of telogen effluvium. The pathogenesis of telogen effluvium caused by contact dermatitis is unknown but may be related to cytokine release during the inflammatory process.- - - - - - - - - - ranking = 12.094181998511keywords = dermatitis, contact (Clic here for more details about this article) |
6/32. netherton syndrome associated with idiopathic congenital hemihypertrophy.netherton syndrome is a rare genodermatosis comprised of anichthyosiform dermatitis, hair shaft defects, and atopic features. Other problems associated with netherton syndrome are delayed growth and development, immune abnormalities, recurrent infections, and intermittent aminoaciduria. We describe an 18-month-old girl with netherton syndrome who had idiopathic congenital hemihypertrophy on her right side with contralateral benign nephromegaly in addition to the characteristic clinical signs of the syndrome. To our knowledge, this is the first case of netherton syndrome associated with idiopathic congenital hemihypertrophy to be reported.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
7/32. Invasive synergistic fungal infection after motor vehicle collision.Primary invasive fungal infections occur after direct contact or direct inoculation of the skin with fungal spores. rhizopus species and aspergillus terreus are opportunistic fungal species that rarely cause disease in immunocompetent hosts. In susceptible patients, infection may progress rapidly. Aggressive surgical debridement and use of systemic antimycotic agents may successfully control disease and prevent systemic dissemination. We describe the case of a patient with a scalp infection, caused by rhizopus species and A. terreus, that occurred after contact with pavement during a motor vehicle collision. Control was achieved with repeated debridement and use of systemic antifungal therapy.- - - - - - - - - - ranking = 0.018836399702169keywords = contact (Clic here for more details about this article) |
8/32. A case of kerion celsi due to Arthroderma benhamiae identified by dna sequences of nuclear ribosomal internal transcribed spacer 1 regions.We describe a case of a 4-year-old boy with a 1-month history of a purulent lesion on his scalp. His hair samples revealed fungal organisms and trichophyton mentagrophytes was cultured from the sample. We analysed the dna sequences of the nuclear ribosomal internal transcribed spacer 1 (ITS1) region of the isolated fungus. These sequences were in accordance with T. mentagrophytes animal 4 type. In mating experiments, our strain only responded to the Arthroderma benhamiae Americano-European race ( ) mating type tester. We speculate that the patient was infected from contact with his pet guinea pig. This is the first case of a clinical isolate of A. benhamiae being identified by dna sequences of nuclear ribosomal ITS1 regions.- - - - - - - - - - ranking = 0.0094181998510847keywords = contact (Clic here for more details about this article) |
9/32. Ectodermal dysplasias associated with clefting: significance of scalp dermatitis.Several clinical syndromes are characterized by ectodermal dysplasia (ED) in association with clefting of the lip and/or palate. The three most commonly recognized entities are (1) the EEC syndrome (ectodermal dysplasia, ectrodactyly, cleft lip/palate); (2) the Rapp-Hodgkin syndrome with ectodermal dysplasia, cleft lip/palate, and mid facial hypoplasia; and (3) the Hay-Wells or AEC syndrome (ankyloblepharon, ectodermal defects, cleft lip/palate). The clinical characteristics of these entities as well as several less common syndromes are reviewed and summarized. The presence of scalp dermatitis in patients with the AEC syndrome and less often the Rapp-Hodgkin syndrome is emphasized.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
10/32. adult onset folliculocentric langerhans cell histiocytosis confined to the scalp.Langerhans cell histiocytosis (LCH) is a pleomorphic disease entity characterized by local or disseminated atypical langerhans cells found most commonly in bone, lungs, mucocutaneous structures, and endocrine organs. Cutaneous disease occurs in approximately one quarter of all cases. Cutaneous findings include soft-tissue swelling, eczematous changes, a seborrheic dermatitis-like appearance, and ulceration. We report a rare case of LCH confined to the scalp with folliculocentric infiltrates. This 32-year-old male patient presented with follicularly based erythema, scale, and pustules unresponsive to topicals and oral antibiotics. The patient's lesions mimicked lichen planopilaris and folliculitis decalvans during the disease process. On hematoxylin and eosin stain, scalp biopsy showed a perivascular interstitial patchy lichenoid mononuclear cell infiltrate that focally abutted follicular infundibula. Prominent mononuclear cells having reniform nuclei were present, and immunoperoxidase stains for CD1a confirmed Langerhans cell differentiation. Serological and imaging workup failed to display systemic involvement.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
