Incidence of Squamous Cell Carcinoma Upstaged to Invasive Squamous Cell Carcinoma During Mohs Surgery.

Objective: We sought to record the incidence and risk factors associated with upstaging squamous cell carcinoma (SCCIS) to squamous cell carcinoma (SCC) during Mohs surgery with the largest sample size to date.

Methods: Patient records of preoperative biopsy-proven SCCIS being treated with Mohs between January 2019 to March 2022 were identified and reviewed. Postoperative diagnoses of invasive SCC proven by dermal infiltration on pathology were identified as upstaged SCCIS.

Cutaneous Manifestations of Sarcoidosis Seen in a Patient with a History of Tuberous Sclerosis.

This case report details a patient with a history of tuberous sclerosis presenting with new-onset cutaneous lesions that turn out to be sarcoidosis. There may be a shared dysfunction of mTOR present in sarcoidosis and tuberous sclerosis. As a dermatologist, it is worth understanding the cutaneous manifestations of both diseases and maintaining a wide differential when new lesions arise in a patient with a history of either disorder.

Leukocytoclastic Vasculitis following the First Dose of the Elasomeran COVID-19 Vaccination.

Our case highlights leukocytoclastic vasculitis as a potential side effect of the elasomeran COVID-19 vaccine. As the elasomeran vaccine becomes more widely available to the public, cutaneous reactions should be noted and looked for as potential side effects of the vaccine. Our patient had a history of immune thrombocytopenic purpura, making this a potential predisposing condition to the development of vasculitis following elasomeran administration.

Granuloma annulare on the palms.

We present the case of a 72-year-old man with a one-week history of a red rash on the palms of both hands. A 4mm punch biopsy revealed interstitial granulomatous inflammation within the dermis and a colloidal iron stain showed increased dermal acid mucin. Immunohistochemical staining for CD68 confirmed the presence of abundant histiocytes within the dermis.

Cutaneous Plasmacytosis Associated with Ehrlichiosis in an African-American Patient.

Cutaneous plasmacytosis is a rare disease that presents clinically with multiple red-brown papules and plaques with minimal to no epidermal change. Histopathologic findings include a perivascular dermal infiltration of polyclonal plasma cells. The etiology of cutaneous plasmacytosis is unknown, but hypothesized to be due to persistent or repeated antigenic stimulation.

A review of intralesional wart therapy.

Background: New treatment options for warts include intralesional wart injection with agents such as vitamin D, measles, mumps, and rubella (MMR) vaccine antigen, Bacillus Calmette-Guerin (BCG) antigen, and candida antigen but there have been limited studies to compare their efficacies.

Objective: The purpose of this systematic review is to compare the efficacy and safety of injectable agents used for the treatment of warts.

Methods: A PubMed search included terms "intralesional wart therapy," "wart injection" and "verruca injection.

Adherence and resource use among psoriasis patients treated with biologics.

Introduction: The emergence of immune-modulating drugs such as biologics has altered the treatment landscape for psoriasis. However, their use presents high financial costs to patients and healthcare systems. Patient demographic and socioeconomic status may influence adherence to biologic medications and usage of healthcare resources.
