Hi, It seems that you are having Perifolliculitis capitis abscedens et suffodiens (PCAS), also known as dissecting cellultis of scalp, usually begins as a simple folliculitis, most often of the vertex and/or occiput, with clusters of perifollicular pustules rapidly followed by abscess and sinus formation......... Nodules range from a few millimeters to several centimeters in diameter and may be firm or fluctuant. Seropurulent fluid may be expressed from fluctuant nodules. Lesions may persist for years and frequently heal with a scarring alopecia. No systemic symptoms are usually evident. PCAS has a strong tendency to recur. It may confused with Acne keloidalis nuchae,Brocq pseudopelade,Tinea capitis or Folliculitis decalvans... Thorough clinical examination by competent dermatologist should be done. And he should advise to perform bacteriologic culture on pus from the discharging perifolliculitis capitis abscedens et suffodiens (PCAS) lesions in order to treat the secondary infection .....and then he shoul start treatment... Oral isotretinoin may be considered the treatment of choice. Intralesional corticosteroids (eg, triamcinolone acetonide) can be injected into boggy nodules and sinus tracts to decrease inflammation. Antibiotics such as doxycycline, ciprofloxacin, rifampicin, and dapsone have been used successfully in PCAS. Oral zinc sulfate has been used effectively and biologic agents such as adalimumab and infliximab have also been successfully employed... Other therapeutic methods are laser, surgery and X ray epilation.. I hope you must be satisfied with my answer.. Ok . So, immediately you consult competent dermatologist....ok Dr.Ilyas PatelMD,DVD
