Pilonidal sinus cyst of the penis: a rare manifestation of a common disease

Abstract

Pilonidal sinus is a chronic inflammatory condition owing to the subcutaneous trapping of hair. Most commonly it is found in the sacrococcygeal region (natal cleft) but rarely it is found on the penis with very few cases reported in the literature worldwide. We are reporting a case of a pilonidal sinus growing on the distal penile shaft with the sinus opening to the mucosal layer of the foreskin, in a young and fit patient. The cyst was removed with a circumcision and found to contain hair. This was confirmed by histology as a pilonidal sinus cyst.

Pilonidal sinus of the penis: Merits of preoperative radiological diagnosis

“…In the penis, although rare, the theory of formation is that the coronal sulcus acts as a cleft where the hair accumulates and is pushed into the shaft of the penis by mechanical forces and the rolling movement at the junction of the glans penis and the uncircumcised prepuce. 9,14 In our case, actinomycosis was found to be present, in keeping with four previously reported cases. 6,9,15,16…”

A Pinpoint Orifice on the Glans Penis of a Young Man

“…1 Some authors propose that local trauma and friction produce subcutaneous trapping of hair, leading to the formation of a cyst and then a sinus to drain the suppuration. 1,2 However, more current reports suggest that these lesions may be localized forms of hidradenitis suppurativa. [3][4][5] Pilonidal sinuses in unusual locations have been reported, including the scalp, neck, abdomen, groin, axilla, and even amputation stumps; these locations correlate with the classic sites of hidradenitis suppurativa.…”

Pilonidal sinus of the cheek: an extremely rare clinical entity—case report and brief review of the literature

“…Pilonidal sinus is typically encountered in the sacrococcygeal region, but rare cases have been described at other unusual sites in around 2.2% cases [ 6 ], notably the axilla [ 7 , 8 ], suprapubic area [ 9 ], periumbilical zone [ 10 – 13 ], inguinal region [ 8 , 11 ], neck [ 8 , 11 ], periungal region [ 14 ], clitoris [ 15 ], penis [ 8 , 16 – 18 ], nipple [ 11 , 19 , 20 ], intermammary region [ 11 , 12 ], interdigital space of foot and hand [ 2 , 21 – 24 ], scalp [ 8 , 11 ], scrotum [ 25 ], endoanal canal [ 26 , 27 ] and the face. The first reported case of extrasacrococcygeal pilonidal sinus (ESPS) was located in the interdigital region and reported in 1942 [ 6 ].…”
