The effect of the COVID-19 pandemic on perceptions of teledermatology
This study aims to assess the pandemic's impact on people's willingness to use teledermatology as well as to investigate influencing factors. We recruited 544 participants through Amazon Mechanical Turk (MTurk) and surveyed them using REDCap. Participants' willingness to use teledermatology before, during, and after the COVID-19 pandemic was measured via a 5-point Likert scale. The survey also included questions regarding factors influencing participants' attitudes towards teledermatology and their sociodemographic characteristics. Of the 185 participants who reported unwillingness to use teledermatology prior to the COVID...

Extranodal NK/T-cell lymphoma primarily presenting as two adjacent slowly growing skin nodules with prominent epidermotropism and CD30 expression, a case report and review of literature
We present a 54-year-old-man who initially presented with two ulcerations on the right lower leg which progressed despite antibiotic therapy. Histologic examination demonstrated dense lymphoid infiltrates exhibiting epidermotropism, angiocentricity and angioinvasion extending into the deep dermis. Immunohistochemical staining demonstrated expression of CD2, CD3, CD8, TIA-1, perforin, and granzyme-B, consistent with a cytotoxic... (Source: Dermatology Online Journal)

Photodermatitis following knee intra-articular hylan G-F 20 injection for osteoarthritis: two cases
Hyaluronic acid (HA) intra-articular injections are increasingly used for the treatment of knee osteoarthritis. Described adverse reactions of HA intra-articular injections include injection site pain or swelling. A 71-year-old man and a 65-year-old woman independently presented with photodistributed lesions shortly after receiving a repeat HA injection (hylan G-F 20) intra-articularly. A punch biopsy was performed which was consistent with a photodrug reaction or hypersensitivity reaction. Two cases are presented to describe a novel presentation of a photosensitivity reaction to HA. (Source: Dermatology Online Journal)

A pearly nodule on an indurated plaque
We present an 81-year-old man who presented for evaluation of an indurated plaque with an exophytic, pearly, skin-red-brown colored nodule with central ulceration on his chest that evolved over the course of several months and was initially suspected to be basal cell carcinoma. Biopsy demonstrated histological features of dermal spindle cell proliferation in a storiform fashion with CD34 positivity confirming a diagnosis of dermatofibrosarcoma protuberans (DFSP). Dermatofibrosarcoma protuberans are rare, slowly progressive soft tissue sarcomas. The rate of DFSP is greatest among African Americans (8.3/1,000,000), occurring...
