Herpes Zoster Case Study: Diagnosis and Treatment Plan
This case study examines a 73-year-old Hispanic female presenting with a painful ulcerative rash consistent with herpes zoster (shingles). The paper covers the chief complaint, history of present illness, clinical assessment, and a structured treatment plan. It discusses the pathophysiology of varicella-zoster virus (VZV) reactivation, the characteristic dermatomal presentation of shingles, risk factors including age and race, and the three primary goals of HZ management: acute antiviral therapy, postherpetic neuralgia prevention, and acute pain relief. Treatment options reviewed include acyclovir, famciclovir, valacyclovir, oral corticosteroids, and topical calamine preparations.
- Chief Complaint and History of Present Illness: Patient presents with painful dermatomal ulcerative rash
- Assessment: Herpes Zoster Diagnosis: VZV reactivation diagnosed as herpes zoster
- Clinical Features and Transmission: Staging, racial susceptibility, and transmission rates
- Treatment Plan and Management Goals: Antivirals, corticosteroids, and topical pain relief

What makes this paper effective
- The case study follows a clear clinical format — chief complaint, history, assessment, and plan — making it easy to follow and professionally structured.
- The assessment grounds the diagnosis in established pathophysiology, connecting the patient's childhood chickenpox history directly to VZV latency and reactivation.
- The treatment plan is organized around three distinct goals, giving the reader a logical framework for understanding the multi-pronged approach to HZ management.
- Multiple peer-reviewed sources are cited throughout, lending credibility to both the diagnostic reasoning and the therapeutic recommendations.
Key academic technique demonstrated
This paper demonstrates evidence-based clinical reasoning: the student moves from presenting symptoms to a differential-supported diagnosis, then anchors each treatment recommendation to published clinical evidence, including acknowledgment of variable research outcomes for oral corticosteroids and antiviral prophylaxis of postherpetic neuralgia.
Structure breakdown
The paper is divided into four functional sections. The first establishes the patient's presenting complaint and relevant history. The second provides a pathophysiology-grounded assessment leading to the HZ diagnosis. The third briefly covers clinical staging and epidemiological factors such as racial susceptibility and household transmission rates. The final section outlines the treatment plan across antiviral agents, corticosteroids, and topical preparations, with commentary on the evidence base for each.
Chief Complaint and History of Present Illness
Chief Complaint: Painful ulcerative rash for the past couple of days.
The patient is a 73-year-old elderly Hispanic female who presents complaining of a painful ulcerative rash that began a couple of days ago. The rash originates on the posterior right back, radiating to the front right side and following a dermatomal pattern. The patient reports that it is highly painful and pruritic; pain worsens when showering or when clothing contacts the affected area. Nothing appears to alleviate the discomfort. The patient self-rates her pain at 7/10. She reports having contracted chickenpox during childhood.
Assessment: Herpes Zoster Diagnosis
The patient reports a painful ulcerative rash that first appeared a couple of days ago. Her symptoms are consistent with a diagnosis of HZ (herpes zoster), commonly known as shingles. This condition arises due to varicella-zoster virus (VZV) reactivation, which occurs when VZV immunity declines as a result of immunosuppression or aging. HZ may develop among individuals of any age group; however, the most predominantly affected group is elderly persons (Sampathkumar, Drage, & Martin, 2009).
HZ normally presents as two distinct conditions: chickenpox (primary infection) and HZ or zoster (the secondary condition) (Cohen, Salbu, Frank, & Israel, 2013). According to the patient, she contracted chickenpox during childhood. Shah, Singaraju, Einstein, and Sharma (2016) note that a majority of individuals contract this virus during childhood and experience a bout of chickenpox. Ultimately, the immune system clears the virus from most areas of the body; however, the virus may remain latent or dormant within the dorsal root ganglia — located adjacent to the spinal cord — or within the skull's ganglion semilunar. Repeated shingles attacks are seldom reported.
