Patient presents with complaints consistent with enterobiasis, commonly known as pinworm infection.  Symptoms include pruritus ani, particularly nocturnal anal itching, which is a hallmark sign of this parasitic infection.  The patient may also report disrupted sleep due to the intense itching.  In some cases, secondary excoriations from scratching may be observed in the perianal region.  Diagnosis is confirmed via the "tape test", formally known as the Graham Scotch tape method, revealing the presence of Enterobius vermicularis eggs.  Differential diagnoses considered include contact dermatitis, hemorrhoids, and other parasitic infections.  Treatment plan includes administration of a single dose of mebendazole or pyrantel pamoate, with a second dose administered two weeks later to prevent reinfection.  Patient education emphasizes hygiene practices such as handwashing, particularly after using the toilet and before eating, regular showering, and frequent changing of undergarments and bed linens to minimize transmission and recurrence.  Follow-up appointment scheduled in two weeks to assess treatment efficacy and reinforce preventative measures.  ICD-10 code B80 will be used for billing and coding purposes.
