Under specific light illumination, skin produces peculiar fluorescent aspects. Such property can be used to provide diagnostic arguments or to disclose some peculiar functions of the skin. Some superficial infections (erythrasma, tinea versicolor, dermatophytic tinea,..) reveal fluorescence that may be intense. The pilosebaceous follicles enriched in Propionibacterium spp show fluorescence. Such property is lost during some anti-acne treatments. A quenching effect is observed after application of sunscreens. The (pre)neoplastic areas prepared for dynamic phototherapy become fluorescent. Pyranine labeling of the stratum corneum exhibits fluorescence allowing the assessment of the renewal activity of the epidermis. [less ▲]

Skin diseases associated with Bartonella infection: facts and controversies.

The genus Bartonella is composed of a series of species and subspecies. Ten of them are responsible for human infections. The best-identified diseases are cat scratch disease (B henselae and possibly B clarridgeiae), trench fever (B quintana), bacillary angiomatosis (B quintana and B henselae), and the spectrum of verruga peruana, Carrion disease, and Oroya fever (B bacilliformis). Controversies exist about the implication of a few other microorganisms being involved in these diseases. Several other conditions have been associated with the presence of Bartonella spp, but these observations await confirmation. [less ▲]

Hair loss, also called hair effluvium is often considered as an ancillary complaint. However, this situation is quite common in both genders. It is part of numerous clinical presentations in internal medicine and dermatology. Obviously, any correlation between a biologic abnormality and hair loss does not prove a relationship of causality. In absence of pathogenic diagnosis and causality criteria, chances are low to control adequately hair effluvium by a treatment given by the whims of fate. In addition, the risk and frequency of therapeutic inertia are increased. When the hair loss is not controlled and/or compensated by growth of new hairs, several types of alopecia inexorably develop.

Faire un faux pas face a des syphilides "de deuxieme floraison".

In a recent past, the incidence of syphilis has increased in various geographical regions, particularly in urban areas. In addition, the disease is particularly associated with HIV infection. In secondary syphilis, the diagnosis may prove to be particularly difficult to reach because the clinico-pathological resemblance with other skin disorders is commonly high. The risk of diagnostic roaming is associated with therapeutic inertia which is highly prejudiciable to the patient. [less ▲]

Cutaneous malignant melanoma represents one of the most dramatic skin cancers because its incidence is steadily growing in White populations. Of note, its metastatic risk and mortality dramatically increase when the primary neoplasm reaches about one millimeter thick. It is believed that angiogenesis and lymphangiogenesis associated with cutaneous melanoma potentially influence the neoplastic progression of the primary tumor and its metastases. In some instances, both the intratumoral and peritumoral microvasculature are correlated to booming of the tumoral growth fraction. In addition, the vascular network serves as a migration path for the intravascular and perivascular neoplastic spread. Hence, the quantification of the microvasculature might help establishing a prognostic factor of evolution. Among the available methods, spectral analysis of immunohistochemical sections highlighting vessels helps defining the microvasculature distribution. The benefit of using spectral analysis is discussed and the modalities of application of this analytical method are scrutinized. [less ▲]
