Key Insight
This is a classic presentation of Erythema Nodosum (EN). EN is a form of panniculitis characterized by tender, erythematous nodules, typically on the pretibial surface (shins). It is a delayed hypersensitivity reaction that can be triggered by infections (like Streptococcal pharyngitis, as suggested by her history), sarcoidosis, inflammatory bowel disease, or certain medications.
