Diagnosis: Recurrent genital herpes simplex (HSV-2)
A 32-year-old male presents with recurrent painful vesicular lesions in the genital region that have persisted for several years. Examination reveals grouped vesicles on an erythematous base, consistent with a viral etiology. The patient reports multiple episodes triggered by stress and illness.
A 32-year-old male with a history of recurrent genital lesions presents to the clinic with complaints of painful vesicular eruptions in the genital area for the past week. Physical examination reveals multiple grouped vesicles on an erythematous base, localized to the penis and surrounding areas. The lesions are tender to palpation and crusted over in some areas.Grouped vesicular lesions: Clusters of vesicles on an erythematous base.Location: Primarily on the genitalia, with possible extension to the perianal region.Tenderness: Lesions are painful and tender to touch.Crusting: Some lesions have progressed to crusting, indicating healing.Associated symptoms: Possible prodromal symptoms such as itching or burning prior to vesicle formation.
The patient reports that his first episode occurred approximately five years ago, characterized by similar vesicular lesions. Since then, he has experienced recurrent outbreaks, typically triggered by stress or illness. He has previously been treated with topical antivirals with limited success, and he has not been on suppressive therapy. His past medical history is significant for anxiety, and he denies any other significant medical conditions. He has no known drug allergies and reports a non-smoker status. He is sexually active with multiple partners and does not consistently use barrier protection.Onset: First episode five years ago, with recurrent outbreaks.Triggers: Stress and illness frequently precipitate outbreaks.Previous treatments: Topical antivirals with minimal improvement; no suppressive therapy attempted.Past medical history: Anxiety, otherwise unremarkable.Social history: Multiple sexual partners, inconsistent use of protection.
Acute / First-Line ManagementAcyclovir: 400 mg orally three times daily for 7-10 days.Valacyclovir: 1 g orally twice daily for 7-10 days.Famciclovir: 250 mg orally three times daily for 7-10 days.Workup and Diagnostic ConfirmationViral culture: Can confirm active infection but is less commonly performed.Polymerase chain reaction (PCR): Highly sensitive and specific for HSV detection from lesions.Serology: May be useful for identifying previous exposure, particularly in asymptomatic individuals.Long-Term ManagementSuppressive therapy: Acyclovir 400 mg daily or Valacyclovir 500 mg daily to reduce frequency of outbreaks.Education: Patient should be educated on safe sexual practices and the importance of disclosing HSV status to partners.Regular follow-up: Assess treatment efficacy and any side effects.
Contact dermatitis: Erythematous vesicles can occur due to irritants or allergens; often associated with pruritus and a history of exposure.Syphilis: Chancre can present as a solitary ulcer; serologic testing is required for diagnosis.Condylomata acuminata: Caused by HPV, presents as warty lesions; usually non-painful and may be associated with itching.Scabies: Pruritic vesicles may occur in the genital region; typically presents with burrows and intense itching.Herpes zoster: Can present with vesicular lesions, but typically follows a dermatomal distribution and is associated with pain.Fixed drug eruption: May present as solitary or multiple vesicular lesions; history of drug exposure is key.Folliculitis: Can present with pustules or vesicles around hair follicles; usually associated with tenderness.
High-Yield PearlsVesicular lesions: Grouped vesicles on an erythematous base are characteristic of herpes simplex virus infection.Triggers: Stress and illness are common precipitating factors for recurrent outbreaks.Suppressive therapy: Daily antiviral therapy significantly reduces the frequency of outbreaks and transmission risk.Education: Patient education on safe sexual practices is crucial in managing herpes simplex infections.Diagnosis: PCR is the preferred method for confirming active herpes simplex virus infection due to its high sensitivity and specificity.Recurrent genital herpes is a manageable condition with appropriate antiviral therapy and patient education.
