 A pilonytal sinus is a type of infected tract located in the skin, usually containing a tuft of hair. It is often found in areas of the body where there is friction between the skin and hair, such as the buttocks or axillary region. This condition is more common among men who have excessive amounts of body hair. When left untreated, this condition can lead to severe pain, swelling and infection. In some cases, it may even require surgical intervention. Our patient presented with a recurring infected sinus on his anterior chest wall, which had been previously treated by other physicians. After careful examination and exploration, we were able to identify the source of the problem of pilonytal sinus. This condition is not uncommon and should always be considered when evaluating patients with long-standing sinuses over hairy areas. This article was authored by Naya Sumro and Hira Purbas.
