Case 1
An inpatient dermatology consult was requested to evaluate white macules on a 22-year-old Hispanic male with congenital HIV hospitalized for progressive dyspnea and pyrexia. The patient reported that his skin findings first appeared at 18 years of age and had remained unchanged and asymptomatic. At the time of consultation, the patient was not taking highly active antiretroviral therapy (HAART) and had a CD4 count of 83 cells per microliter (normal range, >500 cells/μL) and a viral load of
Case 2
A 32-year-old African American HIV-positive male with acne vulgaris, pruritus of HIV, common warts, and condyloma acuminatum presented with a 4-month history of numerous flat-topped papules on his trunk. The patient was compliant on HAART therapy with a CD4 count of 253 cells per microliter and viral load of less than 50 copies per milliliter at the time of presentation. He was treated with narrowband ultraviolet B (NBUVB) light phototherapy for the previous 14 months for pruritus and topical
Discussion
The pathogenesis of congenital EV remains unknown. In 2002, families with EV were found to have missense mutations in the EVER1/TMC6 or EVER2/TMC8 genes on chromosome 17q25. These genes encode a cytoplasmic protein that colocalizes with calnexin, an integral membrane protein in the endoplasmic reticulum.2 However, the function of these proteins has yet to be elucidated. It has been hypothesized that the mutations down-regulate cell-mediated immunity by decreasing the ability of cells to present
Conclusion
With the prolonged survival of immunosuppressed patients and increased clinical awareness, we expect the incidence of AEV to continue to rise. There is currently no definitive treatment for the congenital or acquired forms of EV, and the risk of progression to malignancy in the immunosuppressed patient remains unknown, although likely. Therefore, as dermatologists, we must be diligent in performing regular full body skin exams on these patients and have a low threshold for biopsy and treatment

2023, JAAD Case ReportsCitation Excerpt :Sometimes they coalesce to form wart-like papillomatous lesions.1 Classically, EV was thought to be a purely genetic condition until Rogers et al2 coined the term “acquired EV” reporting the development of EV in immunocompromised patients. This landmark publication led to an influx of reports of similar cases; more than two-thirds of the publications about acquired EV came after this report, as documented by Limmer et al.3 Significant interest in understanding the etiology and pathogenesis of this condition stems not only from the psychosocial impact of EV on patients but also from patients’ increased susceptibility to develop nonmelanoma skin cancers, especially squamous cell carcinoma.
