Intermammary pilonidal sinus: rare location of a common condition

Pilonidal sinus in the intermammary region is a rare location of an inflammatory condition commonly occurring in the natal cleft. It is typically characterised by a pus and hair containing cavity in the skin lined by granulation tissue connecting the skin surface. A 22 year-old female presented with chronically discharging sinuses in the intermammary region with recurrent abscess formation for one year duration. Although a rare location, clinical diagnosis of pilonidal sinus was made. Complete excision of sinus tract with abscess cavity with primary closure was performed under general anaesthesia. Histopathological examination confirmed pilonidal sinus. On follow up, the scar was healthy with no keloid formation. Pilonidal sinus may rarely occur in intermammary region. Complete excision and primary closure is the mainstay treatment.
