Two Features of Annular Lichenoid Dermatitis of Youth (ALDY).

A healthy 14-year-old boy presented with a 2-month history of two slowly expanding asymptomatic lesions on his right trunk. No etymology of any new medications, recent travel, or tick bites was reported. Physical examination demonstrated two 4.5×2.5- cm and 3.5×2-cm annular hyperpigmented plaques with slightly elicited red borders on the right lower abdomen and right inferior flank. No evidence of atrophy or sclerosis was noted (Figure 1A). A 4-mm punch biopsy revealed irregular epidermal hyperplasia with alteration of thinned and quadrangular rete ridges, a dense band-like lichenoid infiltrate in the papillary dermis admixed with numerous melanophages and occasional necrotic keratinocytes. No evidence of epidermotropism was observed (Figure 1B). The dermal infiltrate was predominantly composed of CD3+ T-lymphocytes admixed with rare CD20+ B-lymphocytes and increased CD8-CD4 ratio. The patient showed significant improvement following the application of a potent steroid ointment for several weeks.

Cytophagic histiocytic panniculitis leading to a diagnosis of acute myeloid leukemia with monocytic differentiation: A case report and literature review.

Cytophagic histiocytic panniculitis (CHP) is associated with a number of systemic conditions and is characterized by the presence of benign phagocytic histiocytes ("bean bag cells"), including phagocytosed erythrocytes, leukocytes, and platelets. We describe a case of a 72-year-old female who presented with a papular eruption that clinically mimicked pityriasis lichenoides et varioliformis acuta (PLEVA). Given that her skin biopsy had multiple features concerning PLEVA, this diagnosis was classified as a superficial pityriasis lichenoides-like variant of CHP. The histopathologic presence of cytophagic histiocytosis prompted workup for a systemic malignancy, leading to a diagnosis of underlying acute monocytic leukemia of myeloid lineage.

Subcorneal Pustular Dermatosis Following SARS-CoV-2 Infection.

Subcorneal pustular dermatosis (SPD), also called Sneddon-Wilkinson disease, is a rare, relapsing pustular dermatosis.1 SPD has been associated with multiple myeloma, IgA Gammopathy, pyoderma gangrenosum and certain autoimmune diseases.2 However, SPD occurrence following SARS-COV-2 has not yet been reported. Herein, we report a case of SPD occurring after SARS-CoV-2 infection in a 52-year-old male. We hypothesize that the occurrence of SPD shortly following SARS-CoV-2 infection suggests the viral illness may have precipitated onset of SPD, and the patient may remain at risk for future flares of disease despite appropriate treatment and current remission status.

Off-Label Use of Baricitinib in Dermatology.

The current US Food and Drug Administration (FDA) indications for baricitinib include alopecia areata, rheumatoid arthritis, and COVID-19. However, increasing evidence indicates that baricitinib is effective in treating a variety of dermatological conditions. This review article comprehensively presents the available literature on this topic and will be of interest to practitioners in the field. These disorders may be broadly classified as connective tissue diseases, eczematous dermatoses, alopecias, vascular disorders, granulomatous diseases, neutrophilic dermatoses, vitiligo, psoriasis, lichenoid disorders, and other miscellaneous disorders.

Coffee, Citrus, and Alcohol: A Review of What We Drink and How it May Affect our Risk for Skin Cancer.

Climate change and environmental health are closely linked with agriculture and food supply. The environment influences accessibility, quality, and variety of foods and drinks that are available for consumption, which in turn influences population health. A growing area of research is the role of dietary intake of nutrients and how they may influence risk for skin cancer. In recent years, our group has studied dietary nutrients, particularly those found in commonly consumed beverages, such as those containing caffeine, citrus products, and alcohol, in large prospective cohorts to evaluate how their intake may influence risk for skin cancer. Our data suggest that intake of citrus juices, when consumed around once per day or more, or around 5 to 6 times per week, may be associated with increased risk for both keratinocyte carcinomas (KC) and malignant melanoma (MM). With regards to alcohol consumption, we have found that intake of white wine may be associated with increased risk for both KC and MM, while beer and red wine have not shown such associations. Lastly, our work suggests caffeinated beverages, including coffee, tea, and cola, may be associated with decreased risk for basal cell carcinoma (BCC) and MM. While the associations between food intake and skin cancer development are complex, and remain to be further analyzed in future studies, we hope that our summary may help guide individuals to small changes they may make towards potentially reducing their risk for certain skin cancers.

Considering Sun Safety Policies in the United States.

As they are collectively the most common malignancies, the personal and systemic burden of skin cancers represent a significant public health concern in the United States. Ultraviolet radiation from the sun as well as from artificial sources such as tanning beds is a carcinogen well-known to increase the risk of developing skin cancer in individuals. Public health policies can help mitigate these risks. In this perspectives article, we review sunscreen and sunglasses standards, tanning bed utilization, and workplace sun protection guidelines in the US and provide focused examples for improvement from Australia and the United Kingdom where skin cancer is a well-documented public health concern. These comparative examples can inform interventions in the US that have the potential to modify exposure to risk factors associated with skin cancer.

Understanding melanoma in situ: Lentigo maligna surgical treatment terminology and guideline adherence, a targeted review.

BACKGROUND: Malignant melanoma in-situ, lentigo maligna (MMIS-LM) can be successfully treated with several different surgical techniques; however, the literature is inconsistent in defining them. OBJECTIVE: To comprehensively define and describe the national guideline recommended surgical techniques used to treat MMIS-LM to help clarify and standardize this terminology to ensure compliance with the guidelines. METHODS: A targeted literature review was performed from 1990 to 2022 focusing on articles that discussed the national guideline recommended surgical techniques of wide local excision, Mohs micrographic surgery (MMS), modified Mohs surgery, and staged excision/Slow-Mohs for MMIS-LM, as well as the related methods of tissue processing. National Comprehensive Cancer Network and American Academy of Dermatology guidelines were reviewed to identify how the techniques need to be employed to be compliant with guideline recommendations. RESULTS: We describe the various surgical and tissue processing techniques and discuss advantages and disadvantages of each. LIMITATIONS: This paper was styled as a narrative review defining and clarifying terminology and technique and does not investigate these topics more broadly. CONCLUSION: Understanding the methodology and terminology for these surgical procedures and tissue processing methods is critical so that both general dermatologists and surgeons can employ these techniques effectively for optimal patient care.

When Surgery Won't Cut It: Successful Management of Eruptive Squamous Atypia With Combination Medical Therapy.

The termeruptive squamous atypia(ESA) is used to describe squamous proliferations that do not present with high-grade histologic features and for which surgical management may exacerbate the condition. Non-surgical management of ESA with radiation, local or systemic chemotherapy, retinoids, or immunotherapy have been reported with variable success. In contrast, combination treatment with retinoids, immunomodulatory or chemotherapeutic agents may result in a more durable response. We report a case of recalcitrant ESA of the lower extremities where complete clinical remission was induced with triple combination medical management with intralesional 5-fluorouracil, field treatment with topical 5-fluorouracil and imiquimod, and oral acitretin. Our case adds to the literature supporting combination medical therapy for challenging cases of ESA.

Annular Basal Cell Carcinoma Expanding Around Central Hypertrophic Scarring: A Case Report.

A case of annular basal cell carcinoma (BCC) with central atrophic scarring that developed secondary to spontaneous regression has been reported. We present a novel case of a large, expanding nodular and micronodular BCC with annular morphology with central hypertrophic scarring. A 61-year-old woman presented with a two-year history of a mildly itchy lesion on the right breast. Previously diagnosed as an infection, the lesion persisted after treatment with topical antifungal agents and oral antibiotics. Physical examination revealed a 5x6 cm plaque consisting of a pink-red arciform/annular edge with an overlying scale crust and a large, centrally positioned, firm, alabaster-colored portion. A punch biopsy of the pink-red rim revealed nodular and micronodular BCC features. A deep shave biopsy of the central bound-down plaque showed histopathology of scarring fibrosis with no findings of BCC regression. The malignancy was treated with two sessions of radiofrequency destruction, which led to the resolution of the tumor with no recurrence to date. Contrary to the previously reported case, BCC in our case was expanding, associated with hypertrophic scarring, and showed no signs of regression. We discuss several possible etiologies of the scarring centrally. With further awareness of this presentation, more such tumors can be detected at early stages to facilitate prompt treatment and prevent local morbidity.

Acquired port-wine stains: A report of two cases and review of the literature.

BACKGROUND: Acquired port-wine stains (APWS) are rare vascular malformations that share the same clinical and histological features as their congenital counterparts. Rare cases of AWPS secondary to trauma or in association with medications have been reported in the literature. PATIENTS AND METHODS: We report two cases of APWS. One case appeared at the age of 2 months, the earliest reported in the literature and continued to evolve till the age of 3 years presenting with multifocal distribution mainly affecting the lower face. The second case developed during oral isotretinoin intake and persisted after discontinuation of the treatment. RESULTS AND CONCLUSIONS: The second patient declined treatment, but the first patient had a remarkable improvement following treatment with the pulsed dye laser, which remains the standard of care for capillary malformations on the face.
