Epidermal cyst is a benign lesion which is commonly encountered in practice, and malignant transformation of it is rare. There are few case reports in the literature about malignant transformation of an epidermal cyst into a squamous cell carcinoma. We present a case of squamous cell carcinoma arising from a 3-year epidermal cyst in the right temporal area of a 68-year-old man. The epidermal cyst was initially identified as a spot and treated with laser therapy. However, it recurred, leading to three surgical interventions at a different surgical clinic. Despite these procedures, the cyst persisted, leading to presenting to our department of plastic and reconstructive surgery. He presented with a 2.5cm sized subcutaneous mass with skin ulcerative lesion. After excision, histopathological examination confirmed squamous cell carcinoma from a ruptured epidermal cyst, with clear resection margins. This case underscores the importance of routine histological examinations in excision of epidermal cysts.

Because facial nerve injuries affect the quality of life, leaving them untreated can have devastating effects. The number of patients with traumatic and iatrogenic facial nerve paralysis is considerably high. Early detection and prompt treatment during the acute injury phase are crucial, and immediate surgical treatment should be considered when complete facial nerve injury is suspected. Symptom underestimation by patients and clinical misdiagnosis may delay surgical intervention, which may negatively affect outcomes and in some cases, impair the recovery of the injured facial nerve. Here, we report two cases of facial nerve injury that were treated with nerve grafts during the subacute phase. In both cases, subacute facial nerve grafting achieved significant improvements. These cases highlight surgical intervention in the subacute phase using nerve grafts as an appropriate treatment for facial nerve injuries.

A 76-year-old woman, initially thought to have a simple abscess on her right upper eyelid, presented to our department of plastic and reconstructive surgery. Enhanced three-dimensional facial computed tomography (CT) revealed an abscess on the right upper lid, with a pyomucocele present in the right frontal sinus, accompanied by bone erosion in the superior wall of the right orbit. Based on the results of the CT scan, we diagnosed an atypical Pott’s puffy tumor (PPT) with an abscess on the upper lid originating from the frontal sinusitis. First, surgical incision and drainage were performed in our department, and a percutaneous vacuum drain was placed. To provide a more definitive treatment, endoscopic sinus surgery (ESS) was subsequently performed by otorhinolaryngologists. The patient was discharged without any complications 5 days after ESS. At a 1-year follow-up, no recurrence or notable neurological symptoms were observed. In the case we observed, the patient presented with an upper eyelid abscess and cellulitis, indicating possible orbital involvement. For such patients, a CT scan is necessary. Given the possibility of PPT, it is critical to perform a comprehensive differential diagnosis rather than defaulting to a straightforward approach involving abscess treatment.

Nail growth disturbance commonly takes place after trauma or relevant diseases, such as infections and tumors. However, abnormal growth of the nail plate sometimes occurs without an obvious causative factor. This report presents the case of a patient who underwent male genital reconstruction with a radial forearm free flap for gender affirmation. Although the entire process was smooth, with no accidental events, the second, third, and fourth phalangeal nail plates of the hand from which the flap was harvested showed no evident growth of the fingernail 2 months postoperatively. Nail production was preserved in the remaining fingernails. Typical symptoms, such as redness, swelling, and tenderness, were noted upon clinical observation. Eventually, nail production restarted 5 months after surgery. Steroid and antibiotic treatment was attempted to reduce periungual inflammation. Additionally, close observation with psychological support was conducted.

The incidence of high-pressure injection injuries is increasing with the development of industry and use of injectors. Although high-pressure injection injuries are relatively rare, they commonly lead to complications such as skin necrosis, infection, and amputation. Moreover, the initial presentation is prone to be underestimated because of the small entry point at the patient’s first encounter in emergency care. A prompt surgical intervention is required, with appropriate and rapid initial treatments, including broad-spectrum antibiotics and tetanus toxoid. The surgical treatment involves wide debridement for foreign material removal and subsequent reconstruction. In this case report, we present three cases we encountered and the ensuing complications. All three patients who received the same treatments are discussed in detail.

Myxoma is a locally invasive neoplasm usually involving the jaw bones, typically occurs between the second and fourth decades. This tumor may comprise 3%-6% of odontogenic tumors. Myxomas of the soft tissue of the face are very rare. We present an unusual case of myxofibroma occurring in a 13-year-old man involving the soft tissue of the face. It congenitally occurred and was a 1 cm sized, ovoid in shape, swelling located on the glabella without any symptoms. An excisional biopsy was performed. A well encapsulated ovoid mass was attached to the corrugator supercilli muscle below the frontalis muscle. It was measured 1.1 x 1 x 0.8 cm and completely excised. Histological examination revealed myxofibroma showing stellate and spinde-shaped cells throughout myxoid ground substance. The unusual features of this case are the site of the tumor, which was localized to the non-tooth bearing area of the mandible and its congenital occurrence history.

Background: The efficacy and safety of equine cartilage as a competent xenograft material for rhinoplasty were evaluated and compared to the outcomes of rhinoplasty using silicone implants. Methods: We performed a multicenter, double-blind, non-inferiority, and randomized confirmatory study. Fifty-six patients were randomized 1:1 to the study group (using MegaCartilage-E) and control group (using silicone implants). The Rhinoplasty Outcome Evaluation (ROE) score, photo documentation, Global Aesthetic Improvement Scale (GAIS), and adverse event data were obtained until 12 months after surgery. The primary efficacy, which is the change in ROE score 6 months after surgery, was assessed in the modified intention-to-treat set. The secondary efficacy was evaluated in the per-protocol set by assessing the change in ROE score 6 and 12 months after surgery and nasofrontal angle, the height of the nasion, and GAIS 1, 6, and 12 months after surgery. Results: The change in ROE score of the study group was non-inferior to that of the control group; it increased by 24.26 ± 17.24 in the study group and 18.27 ± 17.60 in the control group (p = 0.213). In both groups, all secondary outcome measures increased, but there was no statistical difference. In the safety set, treatment-emergent adverse events occurred in 10 patients (35.71%) in the study group and six patients (21.43%) in the control group (p = 0.237). There were 13 adverse device events in the study group and six adverse device events in the control group (p = 0.515). Conclusion Processed equine cartilage can be used effectively and safely as xenograft material for rhinoplasty.
