“…While midline dermoids are not infrequently found to invade the cranium, there are fewer than 20 case reports which describe lateral frontotemporal dermoids with associated sinus tracts and bony invasion, of which 7 have extended intracranially [1,2,5,7,8,9,10,11,12,13,14,15]. Intradiploic dermoids represent between 0.04 and 0.7% of all cranial tumors [17].…”

“…They may appear as a lytic defect in the skull, giving a wide differential diagnosis by imaging alone. Frontotemporal dermoid cysts associated with sinus tracts or bony invasion are extremely rare, with only 20 case reports described in the literature [1,2,5,7,8,9,10,11,12,13,14,15]. We present a report of a rare intradiploic frontotemporal dermoid, without soft tissue extension, in the cranium of a 2-year-old male.…”

Background: Intradiploic dermoid cysts represent 0.04-0.7% of cranial tumors. Fewer than 20 cases of dermoid cysts occurring in the lateral frontotemporal region with a sinus tract and bony involvement are described, only 7 with intracranial extension. We present the first report of such a lesion arising within the lateral coronal suture. As the literature on this topic grows, the matter of preoperative imaging for soft tissue and bony lesions of the lateral frontotemporal region is evolving, and this report offers a preliminary set of criteria for when imaging is a necessity. Case Report: A 2-year-old male presented with a bony lesion in the right frontotemporal region. Since birth the lesion had grown commensurately with the patient. Examination revealed an immobile hard mass overlying the right coronal suture with no discernable abnormality. Computed tomography demonstrated a cystic lesion without evidence of intracranial extension. Intraoperatively, the exophytic lesion was fully enclosed by bony matrix, interrupting the coronal suture as it approached the pterion. Following resection, pathology revealed an intradiploic dermoid cyst. Conclusion: Intradiploic dermoid cysts occurring within patent cranial sutures away from the midline are rarely described lesions. Complete surgical resection with careful follow-up is the treatment of choice.

“…They are derived from the sequestration of the surface ectoderm at cranial suture lines during early embryological development [6]. They are lined with a keratinized squamous epithelium and can include ectodermal structures such as hair follicles and pilosebaceous glands with keratin or lipid material.…”

Craniectomy for a Bilobed Dermoid Cyst in the Temporal Fossa and Greater Wing of the Sphenoid Bone

Dermoid cysts are common periorbital lesions. They usually occur near the superolateral orbital rim, indenting but not extending within the bony outer table. We present an unusual case of a dumbbell-shaped dermoid cyst underlying the temporalis muscle with extension into the lateral wing of the greater sphenoid bone, approaching the optic canal. The cyst was successfully removed en bloc via a small skull base craniectomy without spillage of cyst contents. The patient recovered well without neurological or visual sequelae.

Multiple dermoid sinuses of type Vb and IIIb on the head of a Saint Bernard dog

et al. 2013

Dermoid sinus, a congenital malformation of neural tube development, has been reported in humans and several animal species including dogs. It is typically found in the dorsal midline and commonly occurs in the Rhodesian Ridgeback breed. A case of multiple dermoid sinuses in the fronto-occipital region is described. An 11-month-old, intact female Saint Bernard dog was presented with a 2 day history of discharge from a large irregular subcutaneous mass in the fronto-occipital region. The dog was otherwise healthy. The dog had two circular skin lesions (approximately 4 × 4 and 4 × 2 cm diameter) surrounded by multiple irregular elevated masses. The masses had multiple small openings on the skin surface with tufts of hair protruding from the apertures. The masses were surgically removed, and the diagnosis of multiple dermoid sinuses was confirmed by histological examination. Histopathological examination showed multiple, variably sized, spherical to tubular cysts expanding the dermis and subcutis. Cysts were filled with hair shafts and lamellar keratin and were lined by a stratified squamous epithelium. Sebaceous and apocrine gland adnexal structures were also observed. To the best of our knowledge, this is the first reported case of multiple dermoid sinuses of two different types in the head of a Saint Bernard dog.
