Accelerated Progression of Disseminated Coccidioidomycosis Following SARS-CoV-2 Infection: A Case Report.

We describe a patient with subclinical coccidioidomycosis who experienced rapid disease dissemination shortly after SARS-CoV-2 infection, suggesting host immune response dysregulation to coccidioidomycosis by SARS-CoV-2. We hypothesize that disrupted cell-mediated signaling may result after SARS-CoV-2 infection leading to functional exhaustion and CD8+ T-cell senescence with impairment in host cellular response to Coccidioides infection.

Epidermolysis Bullosa Acquisita: A Case Report.

BACKGROUND Epidermolysis bullosa acquisita is a rare, subepithelial bullous disorder, which is distinguished from other autoimmune blistering diseases by the production of antibodies against type VII collagen. CASE REPORT Here, we describe the case of a 79-year-old male resident of the Northern Mariana Islands who presented to the clinic with multiple blistering skin lesions. CONCLUSIONS The primary focus of treatment is to prevent disease progression and serious complications of scarring (including blindness and respiratory obstruction) by avoiding physical trauma and suppressing the immune systems with agents, including corticosteroids, colchicine, dapsone, methotrexate, and cyclophosphamide. Successful treatment of the condition should involve a multidisciplinary team of medical professionals with regular monthly follow-ups during periods of active disease.

Melanoma in an Active Duty Marine.

Given that the majority of active duty service members are young and healthy, potentially malignant diagnoses such as skin cancer may be overlooked. Although melanoma accounts for only approximately 1% of skin cancers, it causes the greatest majority of skin cancer deaths. We present the case of a 27-year-old active duty Marine who presented with a hyperpigmented macule at his lateral neck that was a malignant melanoma in situ. This article reviews risk factors for the development of melanoma, offers guidelines for primary care providers, reviews resources for providers in a deployed or austere environment, offers recommendations for prevention and early diagnosis, and discusses follow up.

Lesions Arising in a Tattoo of an Active Duty US Marine Corps Woman.

Tattoos are ubiquitous in modern society; however, they do not come without risk of medical complications. When complications arise in the military community, a particularly thorough differential diagnosis should be considered based on the increased exposures service members have during deployment and throughout their military career. We present a case of a 38-year-old active duty US Marine Corps woman with worsening skin lesions arising within a tattoo 6 weeks after acquiring the tattoo on her right chest. Given environmental exposures from a recent deployment to the Middle East, a wide differential was considered. Ultimately, a skin biopsy revealed early hypertrophic scar formation responsive to therapy with intralesional triamcinolone acetonide (Kenalog® [ILK]). However, given the Marine had recently deployed and is part of the active duty population, consideration of alternative, albeit rare, etiologies was imperative.

Primary Cutaneous Coccidioidomycosis Presenting as a Recurrent Preauricular Cyst.

A 31-year-old Filipino active duty marine presented with a 2-year history of a waxing and waning nodule on his left cheek that had been incised and drained on multiple occasions. The patient had no significant medical history other than a positive purified protein derivative test with negative chest x-ray finding treated with a 9-month course of isoniazid in 2010. He denied cough, fever, chills, night sweats, weight loss, joint/bone pain, or prior trauma to the area. On initial examination, there was a 1×1-cm erythematous indurated nodule associated with an overlying violaceous scar on his left preauricular cheek. Since the lesion was presumed to be an inflamed epidermal cyst, it was initially treated with 0.1 cc of interlesional triamcinolone acetonide (10 mg/cc). At 1-month follow-up, the lesion was slightly less indurated, but an excisional biopsy was performed to remove the residual nodule. The biopsy showed an essentially normal epidermis with focal dermal fibrosis below which were multiple collections of histiocytes and multinucleated giant cells surrounded by a dense lymphoplasmacytic infiltrate with numerous eosinophils (Figure 1). A few multinucleated giant cells contained large thick-walled spherules, some with endospores, consistent with Coccidioides immitis (Figure 2). Serological tests showed positive serum for C immitis IgG antibodies with low levels of complement-fixing antibodies (1:2). IgM antibodies were negative. Findings from chest x-ray and bone scan failed to reveal evidence of systemic disease. Although the infectious disease physician felt that the patient most likely had primary cutaneous coccidioidomycosis (PCC), since the duration of the infection was unknown and the patient was Filipino, thereby increasing his risk of dissemination, he was placed on a daily regimen of 400 mg of oral fluconazole until his complement fixation titers became undetectable.

Pityriasis versicolor: avoiding pitfalls in disease diagnosis and therapy.

Pityriasis versicolor is common among young active duty members with overactive sweat glands working in humid environments and results in pigmentary changes that can be profound in those with darker skin. This article addresses several issues related to making the correct diagnosis and providing appropriate treatment, as well as the specific challenges military providers may face in these cases.
