Sebaceous carcinomas of the eyelids are uncommon but lethal tumors. Lesions are usually seen in the elderly, predominantly women. The meibomian glands of the tarsus are the most frequent site of origin. Less commonly, the tumor arises in other sebaceous glands, e.g., the gland of Zeis, eyebrow or caruncle. Regardless of the location, sebaceous malignancies must be considered aggressive neoplasms with a potential for regional and distant metastasis. Diagnosis may be difficult, given the low incidence and inconsistencies in histopathologic classification. Treatment requires wide surgical excision with removal of involved regional lymph nodes and exenteration is reserved for those patients with orbital involvement or diffuse intraepithelial neoplasia. Opinions are divided regarding the use of postoperative irradiation or chemotherapy. Recently we experienced 46-year-old male patient with a 12-month history of painless, firm nodule and conjunctivitis due to sebaceous carcinoma of the left upper eyelid. After surgery, serial sections of the entire conjunctiva and eyelids showed a positive cut margin in medial and lateral border. We report herein this patient that supports irradiation as the postoperative treatment of these tumors in selected patients with a review of literatures.

A 13-year-old neutered female Maltese was referred to Veterinary Medical Teaching Hospital of Seoul National University with 8-month-history of gradually enlarging retrobulbar mass in the right eye. On the ophthalmic examinations, exophthalmos, exposure keratitis, and cataract were observed, and menace response was absent in the eye. The fellow eye was normal except for nuclear sclerosis. On the ocular ultrasonographic evaluation, a mass was identified in retrobulbar and periocular region in the right eye. Exenteration was performed in order to remove the mass. Histopathologic evaluation revealed that most part of the mass was composed of epithelial-like neoplastic cells. Invasion into adipose cells and osseous metaplasia around the mass were also confirmed. Based on the radiologic and histopathologic examination, the mass in the right eye was diagnosed as primary retrobulbar meningioma. Eleven months after the surgery, recurrence was not observed.

There are various defects caused by trauma or resection of maignant tumor in the orofacial region, which can be reconstructed with various regional and pararegional flaps. Among these defects, it is very difficult to reconstruct palatal and midfacial defects after maxillectomy and patients have problems in speaking and swallowing of food. Therefore it is very important for surgeons to reconstruct these defects functionally and esthetically and to return the patients to the normal social activity. These defects are usually obturated with prosthodontic appliances to assist the phonation and swallowing. But nowadays surgical reconstruction by various flaps was considered and performed for better rehabilitation. For this purpose the forehead flap, the nasolabial flap, the tongue flap, the sternocleidomastoideous flap, the temporal flap, the latissimus dorsi flap, the scapular flap etc. are used. We reconstructed small-sized plalatal defects with tongue flap, medium-sized palatal and maxillary defects after maxillectomy with temporal myofascial flap and large midfacial defects including eyeball exenteration with latissimus dorsi myocutaneous flaps. Here we are to report 5 cases of these flaps used for the reconstruction of palatal and midfacial defects and consider the versatility, reliability and limitation in use of these flaps.

Background Excessive use of corticosteroids therapy along with gross immunocompromised conditions in the novel coronavirus disease 2019 (COVID-19) pandemic has raised the risks of contracting opportunistic fungal infections. Here, we describe our experience with the implementation of a surgical protocol to treat and reconstruct rhino-orbital-cerebral mucormycosis. Methods A retrospective review of our prospectively maintained database was conducted on consecutive patients diagnosed with mucormycosis undergoing immediate reconstruction utilizing our "Mucormycosis Management Protocol." All patients included in this study underwent reconstruction after recovering from COVID-19. Wide local excision was performed in all cases removing all suspected and edematous tissue. Reconstruction was done primarily after clear margins were achieved on clinical assessment under a cover of injectable liposomal amphotericin B. Results Fourteen patients were included. The average age was 43.6 years and follow-up was 24.3 days. Thirteen patients had been admitted for inpatient care of COVID-19. Steroid therapy was implemented for 2 weeks in 11 patients and for 3 weeks in 3 patients. Eight patients (57.1%) had a maxillectomy and mucosal lining resection with/without skin excision, and six patients (42.8%) underwent maxillectomy and wide tissue excision (maxillectomy and partial zygomatic resection, orbital exenteration, orbital floor resection, nose debridement, or skull base debridement). Anterolateral thigh (ALT) flaps were used to cover defects in all patients. All flaps survived. No major or minor complications occurred. No recurrence of mucormycosis was noted. Conclusion The approach presented in this study indicates that immediate reconstruction is safe and reliable in cases when appropriate tissue resection is accomplished. Further studies are required to verify the external validity of these findings.

직장암의 치료에 있어서 골반부위에 대한 수술후 방사선치료의 역할을 검중하기 위하여 1979년 2월부터 1980년 6월사이에 치료를 닫은 modified Astler-Coiler병기 B2+3, C1, 및 C2+3의 직장암 환자189명에 대한후향적 분석조사를 시행하였다. B2+3병기의 환자는 47명이었으며, Cl 병기는 17명, 그리고 C2+3병기는 125명이었다. 근치적 수술로 41명이 전방절제술을, 143명이 복부회음절제술을, 그리고 5명은 골반장기적출술을 시행받았다. 전체환자군의 5년 생존율 및 5년 무병생존율은 각각 $45.3\%$ 및 $44.1\%$였다. 각 병기별 5년 생존율은 B2+3에서 $63.4\%$, Cl에서 $62.4\%$, C2+3에서 $37.2\%$로서 이는 통계적으로 유의한 차이를 보였으며 (p<0.005), 5년 무병생존율은 B2+3에서 $55.7\%$, Cl에서 $65.7\%$, C2+3에서 $36.4\%$로서 이것도 역시 통계적으로 유의한 차이를 보여 (p<0.01) 병기가생존율 및 무병생존율에 있어 중요한 예후인자임을 알 수 있다. 재발시 가장 많이 침범되는 장기는 간이었으며, 그 다음으로는 폐 및 회음부였다. 전방절제술을 시행받은 환자군에서 복부회음절제술을 시 행받은 환자군보다 보다 좋은 무병생존율을 보였고 방사선에 의한 장합병증의 위험 이 더 높았다. 수술후 방사선치료로 국소재발억제에는 좋은 효과가 있었으나 진행된 병기에서 주로 문제가 되는 원격전이의 발생은 예방하지 못하였다.
