Complex Medical Dermatology - Clinicopathologic Correlation of Erythema
Description
The presentation discusses two cases of full body erythema, emphasizing the clinicopathologic correlations associated with these presentations. The first case is a 54-year-old female with body-wide erythema, a significant medical history, and notable vital signs, which raised suspicion for conditions like toxic shock syndrome and drug eruptions. Despite an initially unremarkable workup, subsequent lab tests and biopsies indicated a CMV infection, leading to effective treatment after a diagnosis of disseminated CMV. The second case presents a patient who also exhibited full body erythema and had a history of dengue; her clinical condition quickly evolved with fluctuating labs leading to a dengue diagnosis confirmed via CDC testing. The discussion highlights the complexities of diagnosing conditions that manifest as erythema, the importance of thorough clinical assessments, and the need for appropriate testing in immunosuppressed patients. Key learning points include understanding the distinct cutaneous manifestations of CMV and dengue, the significance of clinical clues like perianal erosions for CMV, and the presentation differences between dengue and chikungunya. Ultimately, timely diagnosis and treatment can significantly impact patient outcomes.

- The presentation highlights the need for thorough differential diagnosis when encountering generalized erythema.
- In the first case, the patient's full body erythema was ultimately diagnosed as disseminated CMV infection, confirmed through PCR testing.
- Caution should be taken when considering diagnoses such as toxic shock syndrome, particularly when signs do not fully align with typical presentations.
- The biopsies and laboratory findings connecting to CMV were critical in the patient’s management and recovery.
- For the second case, the clinical features suggested dengue fever, which was later confirmed by laboratory testing.
- Generalized erythema can be a manifestation of various conditions, thus requiring a multifaceted diagnostic workup.
- Skin biopsies often yield non-specific results, reinforcing the need for clinical context and laboratory correlation.
- Dengue can present with skin manifestations including full body erythema, petechiae, and purpura, requiring attention to geographical exposure history.
- Patients with full body erythema and fever may require an infectious disease workup to rule out serious conditions like CMV or dengue.
