Anaerobic peptostreptococcal positive case of hidradenitis suppurativa.

A 19-year old girl presented with painful recurrent abscesses in axillae and perineal region of 1 year duration. The abscess used to rupture and drain, resulting in healed sinus and scar formation. Routine investigations were normal. F N A C showed dense suppurative inflammation with macrophages, a few squamous and apocrine cells. Gram stain showed positive tiny cocci in chains. Culture yielded anaerobic peptostreptococcus. Thus the cytological diagnosis of hidradenitis suppurativa was made.
