Pancreatic panniculitis (PP) is a rare cutaneous manifestation of pancreatic disease, often presenting as tender, erythematous, subcutaneous nodules, typically on the lower extremities. It can also affect the upper extremities, buttocks, and abdomen. PP is associated with conditions such as acute pancreatitis, pancreatic acinar cell carcinoma, and pancreatic adenocarcinoma.

Article Synopsis
  • - A 55-year-old woman developed alopecia areata (AA) after a year of treatment with upadacitinib for her atopic dermatitis.
  • - This case is significant as it suggests a potential link between upadacitinib and the onset of AA, a connection not previously documented.
  • - The report emphasizes the usual timeline for drug-induced hair loss and prompts further investigation into the possibility of upadacitinib causing such side effects.

Background: Empirical decisions to select therapies for psoriasis (PSO) and atopic dermatitis (AD) can lead to delays in disease control and increased health care costs. However, routine molecular testing for AD and PSO are lacking.

Objective: To examine (1) how clinicians choose systemic therapies for patients with PSO and AD without molecular testing and (2) to determine how often the current approach leads to patients switching medications.

Treating an acneiform eruption requires the discovery of its etiology. Often, the removal of the offending agent can lead to the resolution of the eruption, resulting in an excellent prognosis. Herein, we present a rare case of a vitamin B12-induced acneiform eruption occurring in a 68-year-old female due to an over-the-counter supplement.

In this case report, we outline a case of a 36-year-old woman who presented to the dermatology clinic with a history of a hypopigmented macule on her lip. After conducting hepatitis C antibody testing and a shave biopsy, the patient was diagnosed with lichen sclerosus. Because of the increased risk for squamous cell carcinoma, she underwent an anogenital exam, where no lesions were found.

Article Synopsis
  • Psoriasis is a long-term inflammatory skin condition with eleven FDA-approved biologic therapies available for treatment.
  • Recent studies have shown that IL-17 and IL-23 inhibitors are more effective for psoriasis compared to TNF-alpha inhibitors and ustekinumab (an IL-12/23 inhibitor).
  • Despite newer treatments, TNF-alpha inhibitors and ustekinumab still have significant roles in therapy, particularly for certain patient groups considering factors like infection risks, patient demographics, treatment resistance, and co-existing health issues.

Article Synopsis
  • TNF-a inhibitors (like adalimumab and infliximab) and the IL-12/23 inhibitor (ustekinumab) are FDA-approved treatments for psoriasis and have potential for treating other skin conditions due to elevated TNF-a levels.
  • High TNF-a levels are also associated with skin diseases such as hidradenitis suppurativa, while IL-12 and IL-23 are linked to conditions like systemic lupus erythematosus (SLE), alopecia areata, and vitiligo.
  • This paper explores the off-label applications of these inhibitors for various skin disorders beyond psoriasis.

Dupilumab is a biologic agent approved by the US Food and Drug Administration for the treatment of atopic dermatitis (AD). Here, we report 2 patients with AD who were treated with dupilumab and subsequently developed facial flushing after consuming alcohol. A possible mechanism of action for this side effect is discussed along with a potential role of dupilumab.

Article Synopsis
  • Phototherapy can be a cost-effective alternative to expensive systemic psoriasis treatments, particularly for patients with moderate to severe disease.
  • Limited access to treatment centers has hindered the use of phototherapy, creating a need for home-based options.
  • A pilot study indicates that a new home phototherapy device, which combines LED UVB light with a coal tar hydrogel patch, outperforms traditional treatments.

Genital and inverse psoriasis can develop in more than one-third of patients who have psoriasis. Psoriatic plaques in the genital and intertriginous skin are challenging to treat because the skin is thin and often occluded, making it more sensitive to certain therapies. Traditional guidelines indicate topical therapies, such as corticosteroids, topical calcineurin inhibitors (TCI), and vitamin D analogs as first-line recommendation in treating genital and inverse psoriasis.

The advent of biologic agents within the past two decades has dramatically improved the treatment of psoriasis and psoriatic arthritis. Given that there now exists 11 FDA approved biologic options available for psoriasis, with more in the pipeline, the therapeutic armamentarium has been greatly enhanced. However, the fact that there are so many available options has also caused confusion for providers.

The outbreak of the novel coronavirus known as SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) causing COVID-19 was first reported in late December 2019. Many patients with psoriasis on biologic therapy have asked their medical providers about the effect of biologics on COVID-19. However, it is currently unknown how biologic therapy for psoriasis might impact patients with psoriasis and COVID-19.

Easily accessible office-based procedures that require minimal resources may facilitate timely surgical management of hidradenitis suppurativa (HS). This review focuses on excision and unroofing as two surgical HS treatments that can be tailored to the outpatient setting. Fifty-five articles were included in our review, representing 3914 patients.

With the emergence of the novel coronavirus disease (COVID-19) viral pandemic, there is uncertainty whether biologic agents for psoriasis may place patients at a higher risk for infection or more severe disease course. This commentary offers patient counseling recommendations based on the current available evidence. While there are currently no specific data for psoriasis biologics and COVID-19, data are presented here from phase III clinical trials of psoriasis biologics on rates of upper respiratory infection, influenza, and serious infection.
