Although its etiology is unclear, it commonly coexists with Wegener’s granulomatosis, sarcoidosis, diabetes mellitus, leprosy, and connective tissue disorders. It is rarely reported in association with erythema nodosum.[1-3] Erythema nodosum is a reactive dermatosis with inflammation of the subcutaneous fat. It typically presents as an acute eruption of erythematous, tender subcutaneous nodules over the pretibial areas. Plantar erythema nodosum is rare and is usually seen in children or people with systemic diseases such as Crohn’s disease, Takayasu’s arteritis and after treatment with infliximab.[4,5] We were unable to find any previous reports of plantar erythema nodosum associated with granulomatous mastitis.eninfo:eu-repo/semantics/openAccessPlantar Erythema NodosumGranulomatous MastitisBreast CancerSarcoidosisDiabetes MellitusLeprosyLetter10.4103/0378-6323.164219822202203263456542-s2.0-84960439376Q3WOS:000372037400022Q2
