We report a case of actinomycotic infection in epiglottis. Actinomycosis in the head and neck area is relatively rare but extremely rare in the larynx. A 63-year old man presented with continuous discomfort of the throat while swallowing. He had a history of oral injury caused by a fish bone a few weeks prior. Upon Examination with a flexible laryngoscope, a whitish round mass was noted at the lingual surface of the epiglottis. Under local anesthesia, a punch biopsy was performed and showed the typical features of actinomycosis. The mass was removed using a Diode laser under suspension laryngoscope. Additive oral antibiotic therapy was done for 2 weeks. No definite recurrence was noted at the operation site and the patient is now free of disease.

연부조직에 발생되는 골육종은 매우 드문 종양으로, 세계적으로 소수의 예가 보고되었으며 한국에서는 2례가 보고되었을 뿐이다. 문헌상 세계에서 최고령의 증례인 91 세 남자에서 외상, 방사선 조사, 화골성 근염, 피부 근염 등과 관련없이 슬관절 주위에 발생한 연부조직 골육종을 경험하였다. 절제술만으로 치료하였으며, 환자는 수술 후 1년 추시 상 생존해 있고 국소재발이나 전이의 징후가 없으며 슬관절의 기능도 양호한 상태이다.

Beta tricalcium phosphate (${\beta}-TCP$) is one of allogenic bone substitute which is known to have interconnected pores that draws cell and nutrients for bone generation. It has been resulted in good outcomes for bone defect coverage or augmentation. However, several studies have also reported negative outcomes and associated complications including unexpected formation of cystic mass, continuous pain and secretion. We present the case of a 36-year-old man with a right cheek cystic mass who had a history of right zygomaticomaxillary (ZM) complex fracture and surgical correction with ${\beta}-TCP$ powder insertion to ZM bone defect. Excisional biopsy under local anesthesia revealed calcified mass in a sinus tract which was found to be connected to the ZM bone defect site in postoperative computed tomography image. Further excision under general anesthesia was performed to remove the sinus tract and fine granules which filled the original defect site. Pathologic report revealed bony spicules and calcification materials with chronic foreign body reaction. Postoperative complications and recurrence were not reported.

Cutaneous squamous cell carcinoma (SCC) is the second most common skin malignancy. This report describes the case of an unusual extensive SCC involving the whole hemiface, which required reconstruction with a combination of a dual vascular free transverse rectus abdominis muscle (TRAM) flap and a skin graft. A 79-year-old woman visited our hospital with multiple large ulcerated erythematous patches on her right hemiface, including the parieto-temporal scalp, bulbar and palpebral conjunctiva, cheek, and lip. A preliminary multifocal biopsy was performed in order to determine the resection margin, and the lesion was resected en bloc. Orbital exenteration was also performed. A free TRAM flap was harvested with preserved bilateral pedicles and was anastomosed with a single superior thyroidal vessel. The entire TRAM flap survived. The final pathological examination of the resected specimen confirmed that there was no regional nodal metastasis, perineural invasion, or lymphovascular involvement. The patient was observed for 6 months, and there was no evidence of local recurrence. Usage of a TRAM flap is appropriate for hemifacial reconstruction because the skin of the abdomen matches the color and pliability of the face. Furthermore, we found that the independent attachment of two extra-flap anastomoses to a single recipient vessel can safely result in survival of the flap.

Purpose: Epidermal nevi are hamartomas of the skin with multiple clinical variants. Normally, epidermal nevi present at an early age, are found on the head and neck area, and have a female predominance. Only very rarely do epidermal nevi have an adult onset. Most lesions are small and giant Epidermal nevi (> 5 cm at its greatest diameter) are quite rare. Huge verrucous plaque was observed on the scalp of a 70-year-old man. He had been reclusive for a long time, and this problem might have played a crucial role in the development of the giant epidermal nevi. Methods: A punch biopsy and MRI imaging were performed. The huge mass was resected. A local flap and split thickness skin graft was used for reconstruction. Results: The histology examination revealed the characteristic findings of epidermal nevus. Postoperatively, the patient did not suffer from complications or recurrence. Conclusion: A rare case of a huge epidermal nevus on the scalp of an elderly man was treated with a surgical excision. This is the oldest patient reported with an adult onset epidermal nevus in Korea.

Chondroid choristomais a rare tumor like lesion of normal tissue in an unusual location. Oral cavity chondroid choristoma is exceedingly uncommon. This lesion is commonly covered by normal oral mucosa and can develop during a whole lifetime. We experienced a case of 57-year-old man who presented as 6-months history of asymptomatic mass on the dorsal surface of the tongue. We performed surgical excision under local anesthesia, and the pathological diagnosis was chondroid choristoma. After surgery, patient was followed up without any recurrence and discomfort. Therefore, we report this case with a review of literature.

Columnar cell variant of papillary thyroid carcinoma (CCV-PTC) is a rare variant representing 0.15-0.2% of all PTCs. The CCV is aggressive, due to its rapid growth, high local recurrence rate, and frequent lung, brain and bone metastasis. Aggressive surgical and medical management are recommended for these neoplasias. The authors experienced a case of CCV-PTC in a 45-year-old man. We performed total thyroidectomy with neck dissection. The patient received radiation and radioactive iodine therapy. There were no recurrences or complications in the following 24 months after the operation. The patient will closely undergo continuous follow up. We present the clinical characteristics, pathology, treatment, and prognosis of the tumor with a review of the literature.

Intramuscular hemangioma is a rare vascular benign proliferation that can occur within any muscle, particularly in the trunk and extremities. In the head and neck region, the masseter muscle is most commonly involved, followed by the periorbital and sternocleidomastoid muscles. Diagnosing intramuscular hemangioma is challenging because there are no characteristic symptoms; instead, magnetic resonance imaging is the best imaging modality to diagnose these lesions. Complete surgical resection is the treatment of choice, although the local recurrence rate is high. Herein, we report a rare case of intramuscular hemangioma located in the zygomaticus minor muscle, which is related to smiling and usually runs along the orbicularis oculi muscle. Distinguishing or separating these two muscles is challenging. However, based on the muscle vector of the midface and radiological findings, the two muscles were successfully separated. The zygomaticus minor was cut very slightly to approach to the lesion and the muscle fibers were split to excise it. A follow-up examination revealed no nerve damage or muscle dysfunction at 4 weeks postoperatively. This rare case may serve as a reference for managing intramuscular hemangioma in the head and neck region.

Complete surgical excision within a margin of normal healthy bone is the treatment of choice for intraosseous hemangioma. A 56-year-old man visited with complaints of a firm, mildly tender, immovable, and palpable mass on the right forehead (size: 1.5×1.5 cm). Non-contrast brain computed tomography performed preoperatively revealed a 1.5 cm heterogenous osteolytic lesion with suspected internal trabeculation in the right frontal bone. Under general anesthesia, a 2 cm transverse incision was made on the forehead skin rather than bicoronal incision. Full-thickness en bloc resection of the frontal bone including the mass was performed. The frontal bone was removed with care taken not to damage the frontal sinus mucosa. The frontal sinus was sealed with a collagen patch (Tachocomb) and a cranioplasty was performed using bone cement. At 6 months postoperative, a clean wound was confirmed without any complications, and there was no local recurrence. Surgical excision of intraosseous hemangioma in the frontal sinus bone can be performed via direct incision or the bicoronal approach. In this case, the direct incision approach was used to achieve smaller scars and faster recovery than the bicoronal approach.
