Geospatial analysis of access to dermatology care in Los Angeles County: a cross sectional study
Geographic maldistribution of dermatologists contributes to disparities in access to dermatologic care. We aimed to investigate the geographic distribution of, and differences in wait times for medical dermatology services in Los Angeles County (LAC). We placed phone calls to 251 dermatology practices in LAC to ask for a new patient appointment for a changing mole. We found West LAC (Service Planning Area [SPA] 5) had the highest number of dermatologists and South LAC (SPA 6) had the lowest (26.1 versus 0 per 100,000 residents, P=0.01). Service Planning Area 6 has a higher non-White, uninsured, and impoverished population ...

Differences in accessing dermatology offices, primary care offices, and emergency departments between Hispanics and Non-Hispanic White Patients
This study aims to determine if differences exist in accessing the emergency department (ED), primary care, and outpatient dermatologic offices for skin diseases between Hispanic and non-Hispanic White patients. This cross-sectional study used nationally representative data from the Medical Panel Expenditure Survey (MEPS) from 2016-2019. A total of 109,337,668 (weighted) patients with any skin disease diagnosed at an ED, primary care, or dermatology visit were identified. Hispanics comprised 13.0% and non-Hispanic Whites comprised 68.8% of this subpopulation. Overall, 94.1% of Hispanic patients attended a primary care visi...

Novel teprotumumab treatment of severe thyroid dermopathy; ototoxicity as an adverse side effect
Pretibial myxedema, more generally thyroid dermopathy, results from mucopolysaccharide accumulation in the dermis, typically between the knee and dorsal foot. Thyroid dermopathy presents in Graves disease, but can occur in Hashimoto thyroiditis, primary hypothyroidism, and euthyroid patients. Treatment of thyroid eye disease with teprotumumab is established in the literature, with few case reports also showing improvement in pretibial myxedema. Reported is a 76-year-old man with thyroid eye disease and pretibial myxedema treated with teprotumumab; improvement was demonstrated in both conditions. He developed "muffled" hear...

A pediatric case of disseminated American cutaneous leishmaniasis in Rio de Janeiro, Brazil
We report a case of a 2-year-old girl vertically exposed to HIV who presented painful and itchy papules throughout her lower limbs with further dissemination of vegetative ulcers all over the body and scalp. The histopathological examination evidenced the amastigote form of Leishmania and the polymerase chain reaction was positive for Leishmania sp. in the tissue sample. The patient was treated with amphotericin B and demonstrated improvement of lesions. Despite successful treatment for American cutaneous leishmaniasis, she developed osteomyelitis related to a bacterial secondary infection over the site of a previous ulcer...

Atezolizumab-induced psoriasiform drug eruption successfully treated with ixekizumab: a case report and literature review
Immune-related cutaneous adverse events (ircAE) are commonly seen with immune checkpoint inhibitors such as atezolizumab. Atezolizumab-induced psoriasis has been previously reported as an ircAE, especially in patients with pre-existing psoriasis. The severity of the reaction influences treatment of the cutaneous eruption. Biologics should be considered as a treatment option for severe refractory psoriasiform eruptions even in patients with complex medical conditions like chronic infections and malignancy. This is the first reported case of successful treatment of atezolizumab-induced psoriasiform eruption with ixekizumab, ...

Bullous impetigo on a young man's abdomen
Bullous impetigo is a variant of epidermal infection by Staphylococcus aureus, representing 30% of impetigo cases. Its clinical appearance may mimic certain autoimmune blistering dermatoses and other cutaneous infections, sometimes necessitating careful evaluation. Herein we present a patient with bullous impetigo in a striking and characteristic appearance and briefly overview the approach to diagnosis, treatment, and prevention.

Pyoderma gangrenosum associated with pseudo-Pelger-Huet anomaly in a patient with idiopathic myelofibrosis
We describe the case of a 70-year-old man with idiopathic myelofibrosis who developed pyoderma gangrenosum. Histological examination showed an infiltrate consisting of granulocytic elements with features of dysmaturity and s egmentation anomalies (hypo- and hypersegmented forms), suggestive of pseudo-Pelger-Hu√ęt anomaly. Methylprednisolone treatment resulted in progressive improvement of pyoderma gangrenosum. (Source: Dermatology Online Journal)

An unexpected case of non-uremic calciphylaxis in a patient with multiple risk factors
A 58-year-old woman with a history of morbid obesity, asthma, and prior warfarin use presented to the hospital with shortness of breath and a three-month history of painful, ulcerated ulcers with retiform purpura of her bilateral distal extremities. A punch biopsy specimen demonstrated focal necrosis and hyalinization of the adipose tissue with subtle arteriolar calcium deposition, findings consistent with calciphylaxis. We discuss the presentation of non-uremic calciphylaxis and review the risk factors, pathophysiology, and interdisciplinary management approach of this rare disease.

Hitchhiking spider: a case of unilateral vasculitis
A 63-year-old man presented with two days of palpable purpura over the right anterior shin and calf with notable point tenderness on the distal mid-calf without any palpable deep abnormality. Localized right calf pain worsened with walking and was associated with headache, chills, fatigue, and low-grade fevers. A punch biopsy of the anterior right lower leg showed necrotizing neutrophilic vasculitis of superficial and deep vessels. Direct immunofluorescence showed non-specific focal granular deposition of C3 within vessel walls. Three days after presentation, a live spider was found and microscopically identified as a male...

Hemosiderotic (pigmented) atypical fibroxanthoma mimicking malignant melanoma
We report a patient who presented with a slowly enlarging pigmented lesion on his left ear that was clinically worrisome for malignant melanoma. Histopathologic evaluation with immunohistochemistry revealed an unusual case of hemosiderotic pigmented atypical fibroxanthoma. The tumor was successfully extirpated with Mohs micrographic surgery, with no recurrence at 6-month follow-up. (Source: Dermatology Online Journal)
