Background
- Inflammatory condition involving the apocrine gland-bearing areas of skin, characterized by recurrent painful draining nodules.[1]
- More common in women and black or biracial individuals.[2]
- Rarely occurs before puberty. Peak age of onset is 11–20 yo in women and 21–30 yo in men.[3]
Clinical Features
- Tender, nodular lesions most often in the axillae (can also affect gluteal folds, inframammary areas, perianal area, and pubic/genitofemoral areas)
- Malodorous drainage
- Pruritis
- Burning
- Erythema
- Hyperhidrosis
- Scarring[4]
Differential Diagnosis
- Epidermoid or dermoid cyst
- Inflammatory acne
- Granuloma inguinale
- Lymphogranuloma venereum
Skin and Soft Tissue Infection
- Cellulitis
- Erysipelas
- Lymphangitis
- Folliculitis
- Hidradenitis suppurativa
- Skin abscess
- Necrotizing soft tissue infections
- Mycobacterium marinum
Look-A-Likes
- Sporotrichosis
- Osteomyelitis
- Deep venous thrombosis
- Pyomyositis
- Purple glove syndrome
- Tuberculosis (tuberculous inflammation of the skin)
Evaluation
- Clinical diagnosis: skin nodules in characteristic sites, may have malodorous drainage
- Diagnosis may be difficult in the ED if single nodule is present.
Management
- Clindamycin 1% topic
- Antibacterial soaps
- Systemic treatments (typically prescribed by specialist): acitretin, finasteride, prednisone
- Incision and drainage should be avoided if possible due to risk of scarring[5]
Disposition
- Discharge with primary care/dermatology followup
