Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

We describe an 11-year-old girl presenting with lichen simplex chronicus (LSC) and acute bilateral carpal tunnel syndrome (CTS) following herpes simplex virus type 1 (HSV-1) infection as evidenced by serological data and by detection of HSV-1 DNA in the blood with the use of PCR. Based on the literature search, this case represents the first childhood case of LSC and acute bilateral CTS followi...

Vulvo-vaginal symptoms are among the most common reasons that women seek health care; upward of 6 million physician office visits are made by women of all age ranges for vulvo-vaginal symptoms. Despite such staggering statistics, most clinicians are not adequately prepared to diagnose and treat chronic vulvo-vaginal symptoms. Overlapping clinical appearance, symptoms, and pathophysiology, compo...

The objective of this paper is to present general considerations which should be kept in mind by clinicians in charge of women with vulvar diseases. Four representative vulvar dermatoses are described. Lichen simplex chronicus is a pathological condition related to chemical and mechanical irritant agents. Detrimental effects of these irritants, in the presence of other dermatoses, have to be co...

Background: Lichen simplex chronicus (LSC), nodular prurigo (NP), and neurotic excoriation (NE) are considered as psychogenic pruritus disorders. Atopic dermatitis (AD) is also classified by some as a psychocutaneous disorder to point out the influence of psychologic factors in its recurrence, persistence and precipitation. AD and psychogenic pruritus share many common features including immuno...

The dysregulation of apoptosis occurs in many cutaneous disease states. Several apoptosis inhibitors have been shown elevated in neoplasms and in some inflammatory conditions, but their relation to proliferative and apoptotic states has not been defined. We examined the expression of the apoptosis inhibitor survivin in a panel of keratinocytic neoplasms and hyperproliferative skin lesions using...
