A 30-year-old man presented to the clinic with a complaint of small painful lumps in his armpit. He stated that he initially experienced some itching and discomfort, but after a while he noticed some red, tender, swollen areas. He also mentioned an odorous yellow fluid that would sometimes drain from the lumps. Since first noticing them 2 years earlier, he reported that the nodules had disappeared and reappeared on their own several times.
On physical exam, several small red subcutaneous nodules were present in the axilla and tender to palpation (FIGURE 1A). The patient also had comedonal acne on his back (FIGURE 1B). The patient’s body mass index was 31, and he was a nonsmoker.
