Annular configuration is conspicuous in the clinical manifestation of many skin diseases and can be helpful for the diagnosis and differential diagnosis. Variations may include arciform, ring-form, annular, circinate, serpiginous, gyrated, polycyclic, targeted or figurate forms, in different colors, sizes, and numbers, with various textures and surfaces. In infectious dermatoses, the annular reactions can be specific or nonspecific, while the underlying mechanisms remain largely unknown. Read More

Context: Inguinal skin is prone to various infectious dermatological conditions such as erythrasma, intertrigo, hidradenitis suppurativa, folliculitis, dermatophytic infection, and various sexually transmitted diseases, as compared to the skin elsewhere.

Aim: Our study attempts to compare the biophysical profile parameters (BPPs) of the genital skin with that of the rest of the body, while taking skin of the upper back as control. It also attempts to find out if there is a difference in BPPs of the two sites and that how the change in the BPPs, bring about change in microbiome and make inguinal skin more prone to infections.

To analyze the clinical and histopathological manifestations, immunohistochemistry, treatment, and prognostic factors of primary, extramammary Paget's disease (EMPD), we systematically reviewed the clinical presentations, histopathology and follow-up courses of 28 patients with primary EMPD. Clinically, their symptoms and morphology mimicked various types of dermatoses, such as seborrheic dermatitis, eczema, candidiasis, tinea cruris and erythrasma, so the initial diagnosis of EMPD was often delayed or missed. Histopathology showed invasive EMPD, and the tumor cells were mostly solid nests or had a glandular structure. Read More
