We report three infants who developed agminated pyogenic granulomas over congenital vascular malformations, all of which had an aggressive growth pattern. There were no precipitating events such as laser therapy or surgery. Lesions were excised. 相似文献

Infantile haemangiomas are among the most common growths during infancy. Their rapid growth during infancy and vascularity can easily cause confusion with other, less common growths. This article focuses on the myriad of diagnostic mimics of haemangiomas, including other vascular anomalies, benign growths, and malignancies. 相似文献

We report four infants born with necrotic caput succedaneum that led to a scarring alopecia with ongoing inflammation and persistent scale-crust. These lesions did not significantly improve with topical or oral antibiotics, but did respond somewhat to topical corticosteroids. Alopecia with chronic erosive scale-crust and a moderate response to topical corticosteroids are findings consistent with a diagnosis of erosive pustular dermatosis of the scalp. 相似文献

Cutaneous vascular malformations are rare disorders representing errors in vascular development. These lesions occur much less commonly but are often confused with the common infantile hemangioma. It is important to properly diagnose vascular malformations because of their distinct differences in morbidity, prognosis and treatment. Vascular malformations may be associated with underlying disease or systemic anomalies. Several of these syndromes are well defined and can often be distinguished on the basis of the flow characteristics of the associated vascular malformation. LEARNING OBJECTIVE: At the completion of this learning activity, participants should have a better understanding of the different types of cutaneous vascular malformations. Because of the importance of proper diagnosis of these lesions, participants should also be better able to direct correct management and treatment. 相似文献

DOCK8 immunodeficiency syndrome (DIDS) represents a rare primary immunodeficiency associated with cutaneous viral infections, allergy, and increased risk of malignancy. We report a case of folliculotropic mycosis fungoides with spontaneous resolution occurring in a patient with DIDS. 相似文献

This report describes a relapse of Salmonella paratyphi B infection in a child with biliary atresia, following 2 weeks of treatment with ciprofloxacin. The recrudescence was complicated by the development of osteomyelitis and was treated with chloramphenicol, trimethoprim, ceftriaxone and ampicillin in succession. 相似文献

动情间期母羊切除卵巢并皮下植入持续释放的E_2后,平均LH基础分泌水平和LH脉冲幅高比对照组显著减低,LH脉冲频率无明显改变。LH的平均基础分泌水平和脉?中幅高显著相关。表明植入E_2对垂体LH分泌的抑制作用主要是抑制LH对GnRH的反应,作用部位在垂体,不在下丘脑。LH基础分泌水平的下降,亦可能是E_2的抑制作用所致。 相似文献

The Asp84Glu variant of the melanocortin 1 receptor (MC1R) is associated with melanoma 总被引:7,自引:1,他引:6

Melanocyte stimulating hormone (MSH) plays an important role in determining
the cutaneous response to ultraviolet radiation and may also influence
melanoma progression. We have previously shown that variants of the
melanocortin receptor present on melanocytes, MC1R, are associated with sun
sensitivity and red hair in a UK population and therefore now consider the
gene as a candidate for melanoma susceptibility. We have compared the
frequency of known MC1R variants in the second and seventh transmembrane
domains in 43 melanoma cases and 44 controls. MC1R variants were more
common in cases than controls (chi 2 = 6.75, 1 d.f.; P = 0.0094) with a
relative risk to carriers of variant alleles compared with normal
homozygotes of 3.91 (95% c.l.: 1.48-10.35), and a population risk
attributable to carriers of 34.6% (95% c.i. 10.7-52.1%). The Asp84Glu
variant was only present in melanoma cases and appears to be of particular
significance. The contribution of variant MC1R alleles was largely
independent of skin type. Variants of the MC1R gene are likely to be
causally associated with the development of melanoma.
