When disease is chronic and extensive, removal of the affected area and the adjacent apocrine glandular zone to 2 cm beyond the diseased portion is the best option to minimize recurrence. The block of tissue excised should be adequately wide and sufficiently deep. To ensure that the deep coils of the apocrine gland are removed, the subcutaneous tissue down to the deep fascia, or at least 5 mm of subcutaneous fat, should be excised. The extent of the sinus tracts is intraoperatively marked by injecting 3-5 mL of a methyl-violet solution. Complete surgical excision is achieved when all color-coded areas are fully removed. In cases where blue-stained areas occurred in the operative field, further re-excisions must be performed to ensure complete clearance. [7]
