Hidradenitis suppurativa, neutrophilic dermatoses and diverticular disease in a young African-American patient.

Hidradenitis suppurativa (HS) is a chronic skin disorder of the terminal follicular epithelium of apocrine sweat glands, manifesting as painful and exudative papules, pustules, cysts or nodules. This inflammatory condition often presents with other systemic and cutaneous disorders. We present the case of an African-American man with HS who was also diagnosed with neutrophilic dermatoses and diverticular disease. Neutrophilic dermatosis was identified based on histopathology findings. Our patient underwent multiple surgeries for flaring of his skin condition. Colchicine and doxycycline were started, but the patient was not able to tolerate them. Humira was planned for treatment of HS and neutrophilic dermatosis but could not be pursued because of the pericolic abscess. Colonoscopy and radiological investigation revealed multiple colonic diverticuli, for which he initially underwent percutaneous drainage followed by surgical removal of sigmoid mass and colocutaneous fistula. Culture from the specimen revealed abnormal growth of Actinomyces.
