A 10-year-old black girl with a severe hypersensitivity reaction to phenytoin is described. Adverse effects included interstitial nephritis, hepatitis, and toxic epidermal necrolysis. An apparently permanent sequela of universal cutaneous depigmentation developed. Although the presence of clear cells in the basal layer of the epidermis suggested that melanocytes might still be present, these clear cells were shown, by electron microscopy, to be Langerhans cells and not melanocytes. This patient demonstrates a unique outcome, not previously described in the literature. 相似文献

A 10-year experience in eighty-six patients confirms the effectiveness of topical carmustine (BCNU) in mycosis fungoides (MF). Complete remission (CR) was achieved in 84% of those with less than 10% involvement (stage IA), median CR, 12 months, and in 52% with greater than 10% involvement (stage IB), median CR, 23 months. The probability of freedom from relapse for 1 year was 72% in stage IA and 37% in stage IB. No deaths in stages IA or IB were attributable to MF. Including all causes of death, the probability of 5-year survival for stage IA was 93% and for stage IB, 48%. Good results were obtained with only local BCNU in fourteen patients with mostly less than 5% involvement. Five of seven with poikilodermatous MF, two with parapsoriasis en plaques (PEP), and three with lymphomatoid papulosis did well. Persistent local therapy cleared deeply infiltrated lesions in some patients. With present schedules, the hazard of bone marrow depression is slight. Erythematous reactions and telangiectasia are troublesome but have not been accompanied by premalignant changes. 相似文献

The diagnostic value of the identification of T cell subsets in skin biopsies from a series of eight patients (clinical stages I-IV) with cutaneous T cell lymphoma (6 with mycosis fungoides and 2 with Sézary syndrome) was determined with an indirect immunoperoxidase technic using commercially available monoclonal anti-T lymphocyte antibodies. Each patient had a mixture of helper and suppressor T cells within both the dermis and the epidermis, although helper T cells predominated approximately 2:1 over suppressor cells in all except two patients. This pattern is not appreciably different from that reported in benign inflammatory dermatoses. One patient with Sézary syndrome who had had an unusually protracted course was found to have a greater number of suppressor cells than helper cells within the epidermis. We conclude that the in situ identification of T cell subsets adds little, if any, diagnostic sensitivity to standard histopathologic methods in cutaneous T cell lymphoma. 相似文献

Parapsoriasis is a group of uncommon but not rare disorders that was created in 1902 as part of a now long forgotten scheme to classify all inflammatory dermatoses. This artificial grouping has led to an enormously confused nosology of these disorders, that are, for the most part, otherwise unrelated. The use of a number of different terms at different institutions and by different physicians to denote the same diseases, together with the use of particular, single terms to denote different diseases, has caused much unnecessary confusion, In this review these terms are examined and an attempt is made to propose a new, unambiguous classification. Using this system, physicians with different views regarding which of the parapsoriases constitute distinct entities should have no difficulty communicating, and should have a clearer frame of reference within which to work. An attempt is made to evaluate critically which of the parapsoriases are distinct entities and whether one or more of them should be considered an early form of cutaneous lymphoma in light of currently available data. 相似文献

Seckel's syndrome consists of multiple congenital anomalies, including bird-headed dwarfism, mental deficiency, and skeletal and ophthalmic defects. We report a patient with this syndrome who demonstrated pigmentary changes, including streaks of brown pigmentation on the neck, groin, and axillae. Histologic examination revealed pigment incontinence. 相似文献

Frequent antihistaminic side effects noted during treatment of depression by tricyclic drugs, as well as the high affinity of tricyclic antidepressants for H1 receptors in mouse neuroblastoma cells, suggest possibly useful antihistaminic properties. We investigated the antipruritic activity of topically applied 5% solutions of doxepin hydrochloride (Adapin; Sinequan) and amitriptyline hydrochloride (Elavil) and compared such activity to that of a 5% solution of diphenhydramine and vehicle alone. Test solutions were applied to 25-cm2 areas on the flexor forearms of forty subjects, and the development of itch to single drops of eight dilutions of histamine phosphate instilled in each area was reported over a 3-minute period. The lowest concentration of histamine able to elicit unequivocal itching in each treated area was the histamine itch threshold (HIT). Doxepin, amitriptyline, and diphenhydramine all produced significantly higher mean and median HITs (p < 0.01) than did vehicle control. Sixty-eight percent of subjects had a HIT ≥2 × 10?4 mg/ml in doxepin-treated areas versus 58% for amitriptyline, 53% for diphenhydramine, and 25% for vehicle. Our data suggest that tricyclic antidepressants are effective topical antipruritic agents. 相似文献

Absence of human leukocyte antigen molecules in skin tumors and some cutaneous appendages: Evidence using monoclonal antibodies 总被引:3,自引:0,他引:3

Four highly sensitive monoclonal antibodies were assessed for their use in an immunoperoxidase technic on cutaneous sections. Three, B2, C23, and 2A1, were found to discriminate basal cell carcinomas (BCCs) from benign proliferative disorders of skin, and 2A1, a monoclonal antibody against the heavy chain component of class 1 human leukocyte antigens (HLA) for the first time directly demonstrated the absence of this structure from the malignant cell membrane. However, the deeper portions of hair follicles were also found to be unlabeled, and further study of benign follicular tumors which may histologically mimic basal cell carcinomas is suggested. 相似文献

Adequate instrument handling and sterilization are important aspects of office surgery. Heat sterilization is the most reliable choice. The steam autoclave is highly recommended. Dry heat is effective but can pose some storage problems. Gas sterilization is useful for heat-sensitive materials but not practical for the private office. Cold "sterilization" is not reliable for incisional surgery. In addition to proper sterilization modality selection, the surgeon must observe important standards of instrument care, packing, and storage. 相似文献
