Pilonidal sinus (PNS): is a sinus tract, or small channel, that may originate from the source of infection and open to the surface of the skin. [10] Material from the cyst drains through the pilonidal sinus. A pilonidal cyst is usually painful, but if it is a draining sinus, the pressure is relieved and patient might not feel pain.
The pooled incidence of OSD in patients with an atypical dimple, as observed in several studies, was significantly higher (8.8%) compared to patients with a simple dimple (0.6%). Given this increased risk, infants with atypical dimples require further evaluation through radiologic imaging and early referrals to neurosurgical specialists.

Congenital dermal sinus is an uncommon form of cranial or spinal dysraphism. [ 2 ] [ 3 ] It occurs in 1 in 2500 live births. [ 3 ] It occurs as a dermal indentation, found along the midline of the neuraxis and often presents alongside infection and neurological deficit. [ 2 ]
Dermoid sinus is thought to be a genetic skin condition in dogs. It is also known as pilonidal sinus. However, unlike pilonidal sinus in humans, the dermoid sinus in dogs is a neural tube defect. [1] Dermoid sinus is sometimes also confused with dermoid cyst (a teratoma). A dermoid sinus is rare in dogs and cats.
He was born June 6, 1925, in Richmond, Virginia, to Lillian and Dr. K.F. Bascom.His father was an anatomist and teacher at the Medical College of Virginia.

Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be primarily derived from remnants of the primitive streak. [1]
Recent studies have classified two types of maxillary sinus septa: primary and secondary. Primary septa are those initially described by Underwood and that form as a result of the floor of the sinus sinking along with the roots of erupting teeth; these primary septa are thus generally found in the sinus corresponding to the space between teeth, as explained by Underwood.
