Objective: To describe the clinical features and epidemiology of leprosy in patients evaluated in a Midwestern dermatology clinic.

Patients And Methods: We performed a retrospective review of clinical and laboratory data from patients with leprosy who were evaluated in the Department of Dermatology at Mayo Clinic in Rochester, Minnesota, from January 1, 1994, through December 31, 2017.

Results: Nine patients, 7 male and 2 female, were identified, ranging in age from 15 to 63 years (mean age, 38 years).

A 46-year-old woman with a 30 pack-year smoking history presented with a worsening eruption on the left cheek that failed to improve with metronidazole gel. The cutaneous eruption spread to most of her face and did not respond to a brief tapering course of prednisone. During the initial evaluation at our institution, approximately 6 weeks after the onset of the cutaneous eruption, the patient had erythematous, crusted plaques on her face and scalp (Figure 1A); they were also present on the V-area of the anterior aspect of the neck and upper region of the chest, the shoulders, and the arms, with isolated lesions on the trunk and legs.

Pneumocystis jiroveci pneumonia is an opportunistic infection associated with substantial rates of mortality in immunosuppressed patients. Prophylaxis recommendations are mostly targeted toward patients with non-dermatologic diagnoses. This study was conducted to determine when dermatology patients treated with immunosuppressive medications should be offered P.

Background: Cutis laxa-like features were observed in a subset of patients with scleromyxedema. Given this observation, clinical and histopathologic features of scleromyxedema were reviewed in correlation with elastic tissue staining.

Methods: We retrospectively reviewed clinical records and histopathologic features from patients with scleromyxedema seen at our institution from 1992 through 2013.

Skin and soft tissue infections caused by nontuberculous mycobacteria are increasing in incidence. The nontuberculous mycobacteria are environmental, acid-fast bacilli that cause cutaneous infections primarily after trauma, surgery and cosmetic procedures. Skin findings include abscesses, sporotrichoid nodules or ulcers, but also less distinctive signs.

Importance: Mutations in the CERC1 gene associated with deficiency in the ADA2 protein (DADA2) have been implicated in the pathogenesis of cutaneous polyarteritis nodosa (cPAN) and early-onset vasculopathy. DADA2 is not only limited to cPAN and vasculopathy but also includes immunodeficiency that affects several cellular compartments, including B cells; however, some patients appear to have a more indolent, skin-limited disease.

Observations: In this report, we describe 2 white siblings (female and male) with a history of cPAN with DADA2 as a result of novel compound heterozygous mutations inherited in trans in the CECR1 gene (c.

In this review, we summarize the recent literature and use case examples to reach diagnostic criteria for the diagnosis of immunoglobulin G4 (IgG4)-related diseases that may be of relevance to the practicing dermatologist.

Purpose: The purpose of this case report was to demonstrate evidence of indocyanine green angiography leakage consistent with choroiditis in a patient with scleroderma.

Methods: In this case report, the patient underwent a variety of tests and examinations, including systemic evaluation, full ocular examination, skin biopsy, indocyanine green, and fluorescein angiography testing. A 52-year-old man had blurred vision centrally in both eyes.

Objective: To determine the population-based incidence of leukocytoclastic vasculitis (LCV).

Patients And Methods: This is a retrospective population-based study of all Olmsted County, Minnesota, residents with a skin biopsy-proven diagnosis of LCV from January 1, 1996, through December 31, 2010.

Results: A total of 84 patients (mean age at diagnosis, 48.

Background: Deep cutaneous fungal infections (DCFIs) are responsible for significant morbidity and mortality, particularly in immunocompromised patients. Although a direct correlation between histopathologic examination and culture is expected, discordant findings may be seen, presenting a unique diagnostic and therapeutic challenge.

Objectives: We sought to determine the correlation between skin tissue cultures and histopathologic examination in patients with DCFI.

Epidermodysplasia verruciformis (EDV) is a rare genodermatosis characterized by susceptibility to human papilloma virus (HPV) infection. An acquired form of EDV has been described in the setting of immunosuppression, including in patients with the human immunodeficiency virus (HIV). We present the case of an HIV-positive, adopted Haitian boy who presented with EDV.

Extramedullary plasmacytoma (EMP) of the skin is a rare indolent neoplasm that shares morphological and immunophenotypic features with plasma cell myeloma (PCM), but the molecular features that distinguish these two entities have not been defined. We reviewed the clinical characteristics, course, and molecular abnormalities in 7 cases of cutaneous EMP (cEMP); 2 patients had primary cEMP and 5 had secondary cEMP. Two patients died of progressive extramedullary plasmacytoma, 1 without PCM; 1 patient who had only a hyperdiploid clone, died within 17 months of the diagnosis of cEMP; and 3 died of PCM.

Livedoid vasculopathy (LV) is characterized by painful purple macules and papules that subsequently ulcerate. The lesions heal over weeks to months resulting in smooth, porcelain-white, atrophic plaque-like areas with surrounding telangiectases and hyperpigmentation. The specific cause of LV is still to be determined and it is believed to be multifactorial in nature.
