Case Reports
Pilonidal sinus of the penis. A report of two cases, one of them associated with actinomycosis.
Pilonidal sinus is a long-standing chronic inflammatory condition which occurs most commonly in the sacrococcygeal area and it is rare in the penis. Two cases of penile pilonidal sinus in patients aged 25 and 28 years are reported and the literature is reviewed. The lesion is acquired and has to be distinguished from balanoposthitis, epidermal cyst and carcinoma. ⋯ Actinomycosis associated with pilonidal sinus of the penis is extremely rare and there are only two previous reports. It is suggested that pilonidal sinus may have been predisposed to the infection with the actinomyces organisms. Information stating that penile pilonidal sinus and actinomycosis may occur simultaneously is necessary to accomplish an early diagnosis.
