Malignant melanoma of the lacrimal sac is extremely rare. To our knowledge, there have been 17 cases of malignant melanoma of the lacrimal sacreported in the literature and no case has been reported in Korea. The authors have experienced a 56 year-old male patient complaining of epiphora and mass in the medial canthal and neck areas for two month duration in the left eye. Excisional biopsy showed typical malignant melanoma which was treated with radiation therapy. Metastasis occurred in spinal cord during follow-up period. Although malignant melanoma of lacrimal sac is very rare, it should be considered in differential diagnosis of a growing tumor in the lacrimal sac.

Itching is a rare symptom in neurological disease. Paroxysmal symptom is uncommon in neuromyelitis optica (NMO) or multiple sclerosis. We describe a 45-year-old woman who presented with paroxysmal pruritus in association with relapse of NMO on two separate occasions. Cervical MRI showed a lesion at a level corresponding to the dermatomal site of the itching. Paroxysmal pruritus could be a predictive symptom of relapse in NMO unless there are other comorbid causes such as systemic diseases, allergy, drug reaction, or emotional stress responsible for the itching.

PURPOSE: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. MATERIALS AND METHODS: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's(R) Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS(R) proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. RESULTS: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. CONCLUSION: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.

Surgical approaches to blowout fracture have been made through a skin inci-sion in the lower eyelid placed just below the eyelashes[a subciliary pproach], a conjunctival approach, a transantral approach, or a combined approach. Authors repaired the orbital floor fracture through the transconjunctival and transantral approaches simultaneously in 4 patients confirmed orbital floor fracture on CT scan from April to September 1998. Transconjunctival approach could avoid ectropion, lower eyelid retraction and transantral endoscopic orbital floor exploration could allow precise determination of fracture size, location, and replacement of prolapsed tissue and placement of implant over the bony defect. So it was possible to repair with a minimal size of implant and could avoid the complications caused by a too large implant in the posteriorly located orbital floor fracture.
