Photodamage spares the distal digits owing to primate-like hand flexion.

Dermatol Online J 2019 Jan 15;25(1). Epub 2019 Jan 15.

Center for Dermatology Research, Department of Dermatology, Wake Forest School of Medicine, Winston-Salem, North Carolina Department of Pathology, Wake Forest School of Medicine, Winston-Salem, North Carolina Department of Public Health Sciences, Wake Forest School of Medicine, Winston-Salem, North Carolina.

Sun-exposed areas of the body - including the face, neck, and extensor forearms - are chronically exposed to UV light and display signs of photoaging. The skin distal to the proximal interphalangeal (PIP) joint is, however, typically spared owing to the natural rest position of the hand. The inward curvature of the fingers, termed the finger flexion cascade, orients the skin distal to the PIP joint toward the ground as in knuckle-walking primates. Read More

Dermatol Online J 2019 Jan 15;25(1). Epub 2019 Jan 15.

Dermatology Research and Education Foundation, Irvine, California.

Development of lentigines in areas of resolving psoriatic plaques is a rare phenomenon that has been reported following various treatment modalities including phototherapy, topical therapies, and biologics. Although the exact mechanism is unknown, evidence suggests that the cause may be multifactorial, with factors such as skin type, sun exposure, inflammation, and immunologic cytokines all playing a potential role. Herein, we present the first reported case of a patient developing multiple lentigines following treatment of psoriasis with the IL-23 inhibitor guselkumab. Read More

A pink enlarging plaque on the plantar foot: amelanotic acral lentiginous melanoma.

Dermatol Online J 2019 Jan 15;25(1). Epub 2019 Jan 15.

Department of Dermatology, Harvard Medical School, Beth Israel Deaconess Medical Center, Boston, Massachusetts.

Acral lentiginous melanomas account for less than 5% of all melanomas, whereas amelanotic melanomas account for around 2-8% of all melanomas. Amelanotic acral lentiginous melanomas are even less common and can often be mistaken for other clinical entities, including pyogenic granulomas, non-melanoma skin cancers, and warts. We describe a man in his 50s with a twenty-year history of a skin-colored plaque on the right plantar foot; after enlargement and failure of wart treatment, a shave biopsy revealed an amelanotic melanoma.
