Pityriasis rosea (PR) usually presents as acute exanthema with oval erythematous-squamous lesions localized on the trunk, arms, and legs with spontaneous remission. We present an unusual case of PR with frequent relapses during a period of 7 years. An 11-year-old white female patient presented with many pruritic erythematous oval lesions on her trunk. Read More

Pityriasis rosea (PR) may have atypical presentations as regards morphology and distribution of the lesions. Recently, several forms of PR considered atypical for the course of the disease have been described. Differently from the typical PR that resolves within 2-12 weeks, relapsing and persistent PR forms (lasting longer than 12 weeks) have been described in adults and children. Read More

Understanding the effects of age on the epidemiology of diseases primarily affecting the skin is important to the practice of dermatology, both for proper allocation of resources and for optimal patient-centered care. To fully appreciate the effect that age may have on the population-based calculations of incidence of diseases primarily affecting the skin in Olmsted County, Minnesota, and worldwide, we performed a review of all relevant Rochester Epidemiology Project-published data and compared them to similar reports in the worldwide English literature. Using the Rochester Epidemiology Project, population-based epidemiologic studies have been performed to estimate the incidence of specific skin diseases over the past 50 years. Read More

Pityriasis rosea is a common self-limiting rash that usually starts with a herald patch on the trunk and progresses along the Langer lines to a generalized rash over the trunk and limbs. The diagnosis is based on clinical and physical examination findings. The herald patch is an erythematous lesion with an elevated border and depressed center. Read More

Background: The etiopathogenesis of (PR), a papulo-squamous skin disease, remains elusive and hypothesized to be caused primarily by human herpesvirus (HHV) 6 or 7 or immune dysfunction.

Aims: The recent increasing incidences of hepatitis B virus (HBV) infections, including asymptomatic occult HBV infections (OBIs), in a densely populated city in India, prompted us to investigate whether PR patients (from varied socioeconomic and immune status) harbor the underlying HBV infections. These cases were also investigated for HHV 6 and 7 infections. Read More

A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dilatation, metallic stent implantation and later overall colonoscopy, coupled with the newfound knowledge of compound Qingdai pill-taking, led to a subsequent diagnosis of ischemic or toxic bowel disease with sigmoid colon stenosis.

This review article focuses on the spongiotic tissue reaction pattern and some of the common entities that practicing pathologists can frequently encounter in their practice. The spongiotic tissue reaction pattern is the single most common one encountered in the routine analysis of inflammatory dermatoses, and the most non-specific one as well. Spongiotic dermatoses include a very large list of disorders which are best grouped under neutrophilic, eosinophilic, miliarial, follicular and pityriasiform forms of spogiosis. Read More

Paraviral exanthems are distinct skin diseases due to infections with different viruses. Although no virus has been identified so far in some exanthems, the main age of manifestation, the clinical course of the exanthem, and the extracutaneous symptoms are suggestive for a viral genesis. While many viral infections are a direct result of the infection, paraviral exanthems reflect the response of the immune system to the infectious pathogens. Read More

Dear Editor, Pityriasis rosea is a common, acute, and self-limiting dermatosis, which is associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7 (1). It predominantly affects individuals of both sexes in their second or third decade of life and is clinically characterized by the occurrence of an initial erythematosquamous plaque followed by the appearance of disseminated similar but smaller lesions one or two weeks later. Several patients develop systemic symptoms such as nausea, anorexia, malaise, headache, fever, arthralgia, and lymphadenopathy that may precede or accompany the eruption; the latter follows the cleavage lines of the trunk creating the configuration of a Christmas tree and spontaneously resolves within 4 to 8 weeks.

Human herpesvirus (HHV) 6 and 7 are involved in the pathogenesis of pityriasis rosea (PR). Our aim was to evaluate the role of the innate immune response in PR through the detection of Toll-like receptors (TLR) 2, 3, 4, 7, 8, and 9 expression in the skin of affected patients and to detect the possibility of being induced by HHV-6 and/or HHV-7 viral coexistence in these patients. Twenty-four patients with PR and 24 healthy controls were included in this case-control study. Read More

Prolonged survival of lesional T cells plays a central role in the pathogenesis of T-cell-mediated dermatoses. We have recently shown that the ubiquitin ligase c-CBL is highly expressed in cutaneous T-cell lymphoma (CTCL) and that its knockdown increases activation-induced cell death, a key pathway for T-cell apoptosis. Here, we extend our work on c-CBL expression in malignant T cells to their nonneoplastic counterparts in benign inflammatory dermatoses. Read More
