Recommendations for Counseling and Education of Service Members on Endemic African Cutaneous Kaposi Sarcoma: A Case Study.

We report a case of Endemic African Cutaneous Kaposi Sarcoma (EACKS) on the lower extremity of an immunocompetent 31-yr-old male service member from Cameroon. Diagnosis was made using clinical and histologic findings. The service member was treated with local radiation therapy with resolution of his tumor.The goal of this article is to educate practitioners to counsel susceptible service members and leadership on the risk of developing EACKS when traveling to Sub-Saharan Africa, monitor for disease development, and guide in the diagnosis and treatment of patients with this rare disease.

Malignant transformation of oral leukoplakia in a patient with dyskeratosis congenita.

Dyskeratosis congenita (DC) is a rare, inherited, bone marrow failure syndrome caused by premature telomere shortening. The classic mucocutaneous triad of clinical features comprises reticulated skin pigmentation, nail dysplasia, and oral leukoplakia. Multiple somatic features, including bone marrow failure, pulmonary fibrosis, and liver disease, are also common. DC significantly increases the risk for malignant transformation, including myelodysplastic syndrome, acute myeloid leukemia, head and neck squamous cell carcinoma, and anogenital cancer. This case report describes a 23-year-old female with malignant transformation of oral leukoplakia to squamous cell carcinoma, demonstrated in a series of biopsies of the same site. Increased surveillance, proper biopsy technique, and a multidisciplinary approach are critical for patients with DC to ensure rapid diagnosis and treatment.

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.

Treatment of Psoriasis in the Deployed Setting.

Psoriasis is a chronic immune-mediated disorder that can be triggered by environmental changes, illness, smoking, or medications. This case describes a 25-year-old, active-duty Marine Corps Sergeant with a severe perideployment psoriatic flare, and illustrates treatment limitations, restricted access to specialized care, and the importance of mitigating triggers in the deployed setting.

Giant Basal cell carcinoma.

Servicemembers are often exposed to extreme environments with sun exposure, often laying the foundation for future skin cancer. Basal cell carcinoma (BCC) is the most common of skin cancers. We present the case of a 36-year-old male active duty Seabee who presents with a left shoulder plaque that initially started as an erythematous papule but has now increased to greater than 6 cm in the past 10 years and is diagnosed as giant basal cell carcinoma (GBCC). Although only 0.5% to 1% of BCCs develop into GBCCs, there is the potential for metastasis and even death. This article addresses the concerning and potentially fatal diagnosis of GBCC, including your initial impressions and differential diagnoses, available treatment options, and ways to prevent it from ever occurring in our military population.
