“…A single midline sinus posterior to the anus is characteristic, and while most affected patients present with acute abscess, some suffer chronic infection with discomfort and a purulent discharge [13]. Additional sinuses are also frequent, often with lateral openings [14]. Pilonidal sinuses often penetrate deep into the ischioanal fossa; however, they would not be expected to penetrate the sphincters and involve the anus [7, 10].…”

Squamous cell carcinoma arising from chronic sacrococcygeal pilonidal disease: a case report

BackgroundSacrococcygeal pilonidal disease is a chronic, well-recognized entity, characterized by the recurrent formation of an abscess or draining sinus over the sacrococcygeal area. It is one of the most common surgical problems. Rarely, chronic inflammation and recurrent disease leads to malignant transformation, most commonly to squamous cell carcinoma (SCC).Case presentationWe describe an extremely unusual case of SCC developing in a 60-year-old patient with a chronic pilonidal sinus complicated by an anal fistula. After wide surgical excision of the pilonidal sinus and fistulas and because of the poor healing process 6 months later, colonoscopy and a percutaneous fistulography were performed, revealing an anal canal-pilonidal fistula. Patient was treated with a more radical surgical resection with a prophylactic loop colostomy, but healing was not accelerated. Multiple biopsies were then taken from the surgical site at the time, which revealed the development of SCC. CT and MRI imaging techniques revealed SCC partial invasion of the coccyx and sacrum. As a result, aggressive surgical approach was decided. Histological examination revealed moderately to poorly differentiated SCC, and the patient was treated with adjuvant radiation therapy postoperatively. Nine months later, recurrence was found in the sacrum and para-aorta lymph nodes and the patient died shortly after. We discuss the clinical features, pathogenesis, treatment options, and prognosis of this rare malignant transformation.ConclusionsThe development of SCC in chronic pilonidal disease is a rare but serious complication. Symptoms are usually attributed to the sacrococcygeal pilonidal disease (SPD), and diagnosis is often made late by histological examination of biopsies. Malignant transformation should be suspected in chronic SPD with recurrent episodes of inflammation, repeated purulent discharge, poor healing, and chronic complex fistulas.

“…Pilonidal disease occurs predominantly in males at a ratio of about 3-4:1. [9] No specific laboratory studies or tests are needed to diagnose pilonidal disease and its sequelae or differentiate it from other disease entities; it is a clinical diagnosis best elicited by history and physical examination findings. Treatment of infection or abscess with oral antibiotics followed by surgical excision of the sinus is practiced.…”

Follicular occlusion tetrad is a symptom complex consisting of four conditions having a similar pathophysiology. It includes Hidradenitis suppurativa, acne conglobata, dissecting cellulitis of the scalp and pilonidal sinus. The exact pathogenesis of this group of disease is unknown but evidence suggests that they share the same pathological process initiated by follicular occlusion in apocrine gland bearing areas. Though each of these conditions is commonly encountered singly, follicular occlusion tetrad as a symptom complex has been rarely reported in the literature.

“…Some authors suggest that fallen hair get stuck in skin because of its prominences at sides and cause a foreign body reaction, which results granulation tissue and eventually causes pilonidal sinus. On the contrary, some authors think that apertures of hair follicles plug and these swollen follicles open up to subcutaneous tissue, yielding abscess formation and causing chronic pilonidal sinus [7][8][9][10][11]. Excessively hairy body, microtrauma of the intergluteal sulcus associated with long periods of sitting, moist and macerated skin because of bad hygiene are risk factors for the disease [7,[12][13][14][15].…”

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. Materials and Methods:Ninety-eight patients who had operation for PS in Atatürk University, Department of General Surgery between January 2012 and August 2014 were included in this study. The patients were categorized into two groups: first, the patients undergone total sinus excision with primary closure (Group 1), and second, patients undergone total sinus excision with modified primary closure (MPC) (Group 2). Among all 98 patients participated in this study, age, sex, type of operation, duration of operation, amount of excised skin, duration of postoperative stay at hospital and complications were evaluated.Results: Forty-four patients (44.9%) underwent primary closure method, while 54 patients (55.1%) underwent MPC method. Mean duration of operation was 39.1 (30-60) minutes, mean diameter of excised material was 9.3 (8-11) cm 2 and mean duration of stay at hospital was 1.4 (1-3) days for the patients in the first group. Meanwhile, duration of operation was 52.2 (35-70) minutes, mean diameter of excised material was 2.6 (2-4) cm 2 and mean duration of stay at hospital was 1.6 (1-3) days for the patients in the second group. There was statistically significant difference between the two groups by means of duration of operation, dehiscence of surgical wound, recurrence and development of general complications (p<0.001, p<0.05, p<0.05 and p<0.005, respectively). According to the multivariate analysis, during surgical treatment of pilonidal sinus, primary closure method increases the rate of complication 6.65 times and MPC method increases the duration of operation 1.2 times. Conclusion:We hereby suggest that MPC method could be a good alternative for surgical treatment of PS, because it causes fewer complications and recurrence. Keywords: Pilonidal sinus, complication, modified primary closure ÖzAmaç: Pilonidal sinus (PS) hastalığı özellikle sakrokoksigeal böl-genin edinsel olduğu kabul edilen bir hastalığıdır. Tedavisinde lokal küretaj, fenol tatbiki, elektrokoter, total sinüs eksizyonuna eşlik eden çeşitli primer veya flep yardımıyla kapama veya sekonder iyileşmeye bırakma yöntemlerinden biri kullanılır. Ancak henüz üzerinde fikir birliği sağlanan bir tedavi yöntemi yoktur. Gereç ve Yöntem:Ocak 2012-Ağustos 2014 tarihleri arasında Atatürk Üniversitesi Genel Cerrahi Kliniğinde pilonidal sinüs hastalığı nedeniyle opere edilen hastalar total sinüs eksizyonu ile beraber primer kapama yapılanlar (Grup 1) ve modifiye primer kapama yapılanlar (MPC, Grup 2) olmak üzere iki gruba ayrıldı. Çalışmaya katılan 98 hastanın yaşı, cinsiyeti, uygulanan operasyonun çeşidi, operasyon süresi, çıkartılan cildin miktarı, postopera...
