Traction alopecia (TA) affects one-third of women of African descent who wear various forms of traumatic hairstyling for a prolonged period of time. The risk of TA is increased by the extent of pulling and duration of traction, as well as the use of chemical relaxation. The frequent use of tight buns or ponytails, the attachment of weaves or hair extensions, and tight braids (such as cornrows and dreadlocks) are believed to be the highest risk hairstyles. TA can also occur in the setting of religious and occupational traumatic hairstyling. In its later stages, the disease may progress into an irreversible scarring alopecia if traumatic hairstyling continues without appropriate intervention. The most common clinical presentation includes marginal alopecia and non-marginal patchy alopecia. A clue to the clinical diagnosis is the preservation of the fringe sign as opposed to its loss in frontal fibrosing alopecia (FFA). Dermoscopy can be helpful in the diagnosis and can detect the ongoing traction by the presence of hair casts. Histopathology can distinguish TA from alopecia areata, FFA, and patchy central centrifugal cicatricial alopecia. Currently, there is no cure. Therefore, it is imperative that clinicians educate high-risk populations about TA and those practices that may convey the risk of hair loss.
In the weeks following recognized local transmission of the Zika virus in the continental United States, reproductive-aged women had a high level of knowledge of the Zika virus, but those considering pregnancy harbored the greatest concern of personal risk of infection.
Primary cutaneous diffuse large B-cell lymphoma is an uncommon and aggressive lymphoproliferative disorder with a rapid growth rate and dismal prognosis. We present the case of a 91-year-old female with an unusual manifestation of primary cutaneous diffuse large B-cell lymphoma, mimicking other more prevalent diseases like chronic non-healing venous ulceration. Dermatopathologic evaluation rendered the correct diagnosis. A discussion of this rare presentation is important for clinician consideration to prevent misdiagnosis and prolongation of proper management in patients with chronic non-healing leg ulcers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
