Purpose: Dermoid cysts are almost always caused by congenital events. The most widely accepted pathogenesis is that the cysts are dysembryogenetic lesions that arise from ectodermic elements entrapped during the midline fusion. We report a rare case of dermoid cyst, which occurred not congenitally but newly in the subcutaneous scar tissue secondary to trauma. Methods: A 26-year-old man had a deep submental laceration caused by a car accident and got a primary wound closure 16 months ago. There were 18 cm-long submental hypertrophic scar and newly developed palpable masses inside the subcutaneous layer at the center of the scar. Initial impression was an epidermal cyst or a thyroglossal duct cyst. Ultrasonographic finding showed two cystic masses inside the scars at the submental area, but impressed dermoid cysts. The cystic masses were completely removed with W-plasty and histological examination were followed.Results: The histological diagnosis was dermoid cysts which were mainly composed of keratotic squamous epithelium in their inner surface linings and numerous skin appendages such as sebaceous glands, sweat glands, and hair follicles in their cystic lumens histopathologically. During the follow-up period of 25 months, there was no recurrence of any subcutaneous mass in the site of scar. Conclusion: We report a very unusual case of dermoid cysts developed by an acquired cause, considering that the accidental inclusion of deep skin elements caused by a trauma can be a critical origin of dermoid cysts.

Purpose: Epidermoid cyst may be congenital or acquired. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Traumatic epidermoid cysts are rare tumors occurring on the nasal tip, especially resulting aesthetic procedure. So, we report a rare case of an iatrogenic epidermoid cyst in the nasal tip following rhinoplasty. Methods: A 44-year old man had undergone rhinoplasty for several times. First time, the previous augmentation rhinoplasty and wedge osteotomy were performed nineteen months ago, lastly implant removal and unknown filler injection were performed one year ago at another local clinic. He had induration and tenderness on nasal tip and dorsum continued for 3 months. We thought that it was caused by the foreign body reaction with residual alloderm in nose. For removal of residual alloplastic material, open approach using transcolumellar incision was done. But, incidentally we found cystic mass on the nasal tip. Results: The findings were of an 0.8×0.5×0.5cm sized round cystic mass containing cream coloured material with a thick cheese-like consistency. The mass was completely excised and submitted for histology. This confirmed the diagnosis of an epidermoid cyst lined by keratinizing squamous epithelium. There was no induration, tenderness or sign of recurrence after excision of the mass. Conclusion: Epidermal cyst of the nasal tip region represents an unusual clinical lesion and it presents as foreign body reaction. And then, our case demonstrates that meticulous surgical approach and suture technique are the keys to prevent iatrogenic nasal epidermoid cyst, especially in secondary rhinoplasty.

Full mouth rehabilitation with iliac bone graft for a patient with traumatic neuroma in mandible

Damaged sensory nerves in the facial area might show spontaneous recovery. However, imperfect regeneration, such as paresthesia, numbness, and painful pathologic regeneration can occur in some cases. Therefore, iatrogenic nerve damage should be avoided during implant placement in patients with alveolar bone atrophy. For placement of implants in the posterior area of the mandible, the corresponding anatomical structures including the inferior alveolar nerve are of concern. Herein, we presented a case of a patient who developed traumatic neuroma after undergoing full mouth rehabilitation with implants in another hospital. Treatment at our facility included the removal of all implants posterior to the mental foramen, followed by an autogenous iliac bone graft performed on the atrophied alveolar ridge of the mandible. Subsequently, implants were placed in the grafted sites. Finally, the patient showed functional and esthetic results.
