Role of skin biopsy in papulosquamous lesions—a comparative study

This study was done to assess the correlation between the clinical diagnoses of papulosquamous lesions made at dermatological clinics and the diagnosis of these lesions at biopsy. Our study lends insight into the list of most common to least common lesions of papulosquamous lesions. This is a cross-sectional study conducted at a dermatological clinic, on those patients who consulted to a dermatologist. This presumptive investigation on papulosquamous lesion was implied on 83 patients as lichen planus, lichen nitidus, lichen striata, lichenoides dermatitis, psoriasis, pityriasis rubra pilaris, pityriasis rosea, pityriasis lichenoides, pityriasis lichenoides et varioliformis acuta (PLEVA) and Reiter’s disease and then the biopsy was performed on these patients for the confirmation of the clinical diagnosis to assess that diagnosis given by biopsy in these patients matched to the clinical diagnosis and whether it showed any deviation from the clinical diagnosis made by dermatologist. The histopathology report confirmed the clinical diagnosis in 67.5 % and gave the diagnosis in 32.5 % of the total number of cases, which means that 32.5 % cases were those in which the diagnosis provided by the biopsy did not match the diagnosis provided by the clinical diagnosis. The total number of cases was 83: lichen planus occurred most frequently, i.e. 32.5 %, biopsy confirmed diagnosis in 21 patients and gave correct diagnosis in six patients, followed by psoriasis ...

We sought to determine whether AD could induce anxiety- and depressive-like symptoms in mice and to identify pertinen...

CONCLUSIONS: Short-term changes in exposure and subsequently in the spectrum of major contact allergens can best be illustrated by clinical surveillance based on routinely collected data and, if needed, preventive measures can be initiated. In addition to time trend analyses, subgroup analyses may offer important clues regarding the identification of sensitizing and eliciting exposures, respectively.

Authors: Merk HF Abstract Coal tar therapy was used for centuries to treat skin disorders characterised by inflammation and skin barrier damage. It has been shown that the aryl hydrocarbon receptor (AhR) is the key target structure for these pharmacological effects of coal tar. Since coal tar has been used less and less because of the carcinogenicity of many ingredients of coal tar, other ligands of AhR were studied. Tapinarof is such a ligand and proved to be a promising new drug to treat psoriasis and atopic dermatitis. Since many endogenous and exogenous ligands of AhR are known, it may be that this &q...

Authors: Bobrova M, Taranik M, Kopanitsa G Abstract The paper deals with neural networks for decision support in diagnosing in dermatology. There were several iterations during development. We classified six diseases using ANN: (1) Psoriasis, (2) Seborrheic dermatitis, (3) Lichen planus, (4) Pityriasis rosea, (5) Cronic dermatitis, (6) Pityriasis rubra pilaris. At first, we used all 35 attributes to conclude skin disease diagnosis with the accuracy of 96.9%. Then, we reduced the set of analyzed attributes by Pearson correlation approach to eight attributes and increased the accuracy to 98.64%. Data collection time ...

Discussion Hypopigmentation can be worrisome for many families because of cosmesis and the worry that “something is wrong.” The normal natural changes in skin-tone over the year due to different light exposure and wide variations within individuals is not something that many people are aware of. Post-inflammatory hypopigmentation is a common cause of hypopigmentation. Vitiligo is the most common cause of depigmentation. Vitiligo is an acquired, depigmenting disorder with typical lesions appearing as milky white macules with distinct margins that are not scaly. Hair (including eyebrows and eyelashes) can be dep...

Conclusion Dermoscopy could be considered a safe and rapid diagnostic tool that assists the clinical diagnosis and differentiation of frequently encountered PSD, and it could minimize the need for invasive skin biopsies with satisfactory reflection of the corresponding structure histopathologic alterations.

Abstract: 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. Immunohistochemical staining with anti-c-CBL antibody was performed on lesional biopsies from a total of 65 patients with atopic dermatitis, allergic contact der...

AbstractOver the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), pap...
