Axillary Swelling 1 (Differential Diagnosis Mastitis)

Left axillary region in a 1.9-year-old boy with a chronic, localized and hemi-spherical swelling. The diagnosis is chronic lymphadenitis of the left axilla after BCG vaccination on the left upper arm some months ago. Depending on the stage of inflammation local treatment with a tuberculostatic ointment, or a total excision of the involved lymph node is superior to a simple incision with the danger of following chronic fistulization. Such a finding in a hairy axilla of a teenager would also fit in with a sudoriparous abscess.
