Pseudolymphoma in Child
Triggers include insect bites or stings, which cause local reactions, or anticonvulsant drugs, which can cause widespread eruptions. Other causes include a broad range of non-anticonvulsant drugs (antihypertensives, lipid lowering agents, and antidepressants, among others), tattoo dyes, trauma, vaccinations, contact dermatitis, folliculitis, and infections (such as varicella, molluscum contagiosum, human immunodeficiency virus [HIV], or Lyme disease). Pseudolymphoma may be seen after scabies infection, particularly in children. Medication-related reactions may include fever, lymphadenopathy, and an erythematous skin eruption. Malaise, arthralgia, hepatosplenomegaly, eosinophilia, and abnormal liver function tests can also be present in medication-related cases.
While pseudolymphoma may occur at any age, it is most commonly seen in early adulthood.
