Under general anesthesia, careful inspection revealed a 3-mm ulcerated site in the depth of the umbilicus from which bits of hair protruded. A vertical skin incision through the umbilicus skirting one side of the sinuses was made. Diathermy cutting was used to minimize bleeding and ensure visibility of the lesion. There were several strands of hair projecting through three sinus openings (Figur...

Pilonidal sinuses (PS) predominantly affect young male adults, usually occurring in the sacrococcygeal region. However, PS occasionally occurs in other parts of the body, referred to as extrasacrococcygeal pilonidal sinus (ESPS). We herein evaluate ESPS ethiopathogenesis and treatment. Of a total of 949 PS cases treated between 2006 and 2011, 21 were of ESPS (2.2% of the total), which were eval...

Background Pilonidal sinus (PS) is considered to belong in the category of follicular occlusion diseases (acne triad). Objectives The aim of our study was to elucidate the pathogenesis of PS by evaluating its cytokeratin (CK) expression. Methods CK expression in nine cases of PS was studied immunohistochemically using six antikeratin antibodies. Results Infundibular-like epithelium contained CK...

Pilonidal sinus is an annoying chronic benign disease causing disability in young adults, mainly affecting the intergluteal furrow. Treatment of this condition remains controversial and is represented by a myriad of techniques available. Most of the techniques are judged against open excision and secondary healing in terms of minimizing disease recurrence and patient discomfort. More recently s...

PURPOSE This study describes and reports the results of a new, minimally-invasive surgical technique for pilonidal disease. METHODS From March 1993 to January 2003, 1,358 patients (out of a total of 1,435 patients) with symptomatic pilonidal disease underwent treatment in a military surgical clinic dedicated for pilonidal disease. Patients were operated on under local anesthesia, utilizing tr...

BACKGROUND The aim of this study was to estimate the frequency and rate of the first 50 common types of invasive procedures in Iran. METHODS Data about the number of all invasive procedures and each type of procedure that were conducted in Iran in 2010 were collected using the main insurance organizations database. These numbers were sorted in an excel database, and the first 50 invasive proc...

OBJECTIVE Pilonidal sinus (PS) is considered to be the acquired disease of especially in the sacrococcygeal region. Various primary or secondary or flap methods, accompanied by one of local curettage, phenol application, electro-cauterization and total sinus excision methods, are used for the treatment of pilonidal sinus. However, currently there is not a single widely accepted treatment method...

Pilonidal sinuses usually occur in the sacrococcygeal area in young men, and occasionally can be found in other ectopic sites. We present a retrospective case review on unusual locations of pilonidal sinuses in the past 4 years. The lesion sites were as follows: one on the penis, two on the scalp, two on the abdomen, one on the neck, two in the groin and two in the axilla. Abdominal and penile ...
