Assessing the Impact of Prior Authorizations on Dermatology Residents.

Introduction: Prior authorizations (PAs) are administrative tasks commonly required by insurers to approve medications or therapies for patients. Dermatology practices frequently employ coordinators to focus on completing PAs, among other solutions. The degree to which this support is offered in academic centers and, importantly, how much time dermatology residents spend on PAs over educational pursuits is largely unknown.

Offering an Off-Label Therapeutic Algorithm for Lichen Planus.

Lichen planus (LP) is a poorly characterized, chronic inflammatory dermatosis notable for violaceous to brown/ black polygonal pruritic papules and plaques, often with lacey scale, and reticular white erosions involving mucosal sites.

Comparison of the Inflammatory Infiltrates in Tumoral Melanosis, Regressing Nevi, and Regressing Melanoma.

Background: Tumoral melanosis (TM) is a histologic diagnosis characterized by abundant pigment-laden macrophages in the dermis. It is generally thought to represent a regressed melanoma, although it has also been reported after benign pigmented lesions as well. Determining the antecedent lesion in cases of TM is of clinical importance to accurately guide therapy and prognostication.

Keratoacanthomatous Changes: Unifying the Histologic Spectrum of Actinic Granuloma.

Actinic granuloma (AG) manifests as annular plaques on sun-damaged skin. There remains no universal consensus on the nosology, etiology, or clinicopathologic criteria of AG as a distinct entity. Broadly, AG is characterized by granulomatous inflammation, multinucleated giant cells, elastophagocytosis, and the absence of mucin and necrobiosis.

Langerhans Cell Histiocytosis With Clinical and Histologic Features of Hidradenitis Suppurativa: Brief Report and Review.

Langerhans cell histiocytosis (LCH) is an uncommon histiocytic disorder in adults. Clinically, this rare entity can mimic other dermatologic conditions, including hidradenitis suppurativa. A case of LCH is reported with clinical and histologic features of hidradenitis suppurativa, along with a review of these unusual findings.
