A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisional biopsy, the patient was diagnosed to have a solitary fibrous tumor. In immunohistochemistry, the patient's solitary fibrous tumor was characterized by the expression of CD34 and CD99 on the neoplastic cells, and negativity for Bcl-2 and S-100. No recurrence or complication occurred for a period of 5 years. The growth of a primary solitary fibrous tumor in the buccal cheek mucosa is extremely rare and has been rarely reported in the South Korean medical literature. A solitary fibrous tumor must be distinguished from other spindle cell tumors. Presented herein is a case of primary solitary fibrous tumor in the buccal cheek mucosa. The relevant literature is briefly reviewed.

The reconstruction of the mandibulofacial defects is a difficult task when there are full-thickness cheek defects involving mandible, inner mucosa and outer skin. There are several reconstructive options for the coverage of large defects, but most of the methods are complicated, and time- and effort-consuming. We hereby present a case of fibula osteocutaneous flap based on a single peroneal artery perforator in the reconstruction of a three-dimensional mandibulofacial defects.

Eccrine spiradenoma is an uncommon benign adnexal tumor originating from the eccrine sweat gland. We diagnosed a eccrine spiradenoma on a 55-year-old man with histopathologic confirmation upon biopsy followed by complete resection, who had visited our clinic with a chief complain of occipital scalp mass. The solitary eccrine spiradenoma occurring in the scalp is rarely to be seen and should be considered as a differential diagnosis for a solitary cystic mass of the scalp.

Sarcoidosis is a systemic inflammatory disease characterized by non-caseating granulomas of unknown origin. Of the fewer than 6% of sarcoidosis cases that occur in subcutaneous tissue, most occur on the face or forearm, but rarely in the toe. A 33-year-old man was admitted to our institute with a 2-cm mass on his chin and a 0.5-cm mass on his right fourth toe. Based on preoperative ultrasonography, epidermal cysts were suspected, and histopathological tests were performed after removing the masses. Histopathologically, the chin and toe tissue samples showed chronic granulomatous inflammation, without necrosis, indicative of sarcoidosis. Chest computed tomography revealed a large number of small nodules in both the interlobar fissures and the peribronchial area, and a large number of small lymph nodes in both the hilar and interlobar node areas. On the basis of the histopathologic and imaging findings, the patient was diagnosed with sarcoidosis. This very rare case of sarcoidosis, occurring in both chin and toe, suggests that thorough evaluation is needed to find other mass when we find sarcoidosis in facial area.

Angiomyolipomas are hamartomatous lesions consisting of smooth muscle bundles, thick-walled blood vessels, and mature adipocytes. They are usually found in the kidneys of tuberous sclerosis patients and more rarely in other organs, such as the liver, the oral cavity, the sinonasal tract, the heart, the large intestines, the lungs, and the skin. Cutaneous angiomyolipoma has shown to be very rare and generally occurs at the ends of the digits, the elbows, the ears, and the nose. Herein, we report the first documented case of angiomyolipoma of the glabellar region.

Maxillary sinus mucocele can occur due to many medical factors such as chronic infection, allergic sinonasal disease, trauma, and previous surgery. However, it occurs mainly after Caldwell-Luc operation, usually more than 10 years after surgery. There are a few cases of maxillary sinus mucocele with ocular symptoms. Also, a case causing ocular symptoms because of invasion to the orbital floor is rare. Therefore, we report a case of a 55-year-old male patient who underwent Caldwell-Luc operation about 30 years ago. Then, symptoms such as exophthalmos, diplopia, and visual disturbance developed suddenly 3 months prior to admission. Computed tomography showed a cyst invading the orbital floor which resulted in eyeball deviation. The orbital floor defect measured approximately 2.5×3.3 cm. Maxillary sinus mucocele was removed through an endoscopic approach. After this, we reconstructed the orbital floor through a subciliary incision. Observation was carried out after three years, and ocular symptoms such as diplopia and exophthalmos did not recur.

Basal cell carcinoma (BCC) comprising several lesions is not uncommon, but nonsyndromic multiple BCCs with parotid invasion are rare entities. We present two cases of multiple sporadic, nonsyndromic BCCs, and one of these cases is a unique case of parotid invasion associated purely with actinic keratosis. In Case 1, a 79-year-old female presented with multiple skin lesions on the face and left hand. All lesions were completely removed by surgery. The pathologic results showed lesions consistent with BCC and some lesions consistent with actinic keratosis. After 8 months, the patient presented with skin lesions in bilateral temporal areas and left cheek area. Surgical excision of the lesions was performed, and the biopsy results were squamous cell carcinoma in situ and actinic keratosis. In Case 2, a 43-year-old woman presented with multiple skin lesions on the face, scalp, right chest, abdomen and right leg. All lesions were completely removed by surgery. Pathologic evaluation confirmed the diagnosis of BCC. BCC is rarely metastatic, but it can lead to severe disfiguration or destruction. It is important to diagnose and treat BCC at an early stage.

We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired. An agreement was reached to remove the shunt device and observe the patient for any neurological symptoms, and after the shunt was removed and the previous cranial opening filled with fibrin glue by Neurosurgery, we debrided the deteriorated flap and provided coverage with 2 large opposing rotational flaps. During 2 months' outpatient follow-up no neurological symptoms appeared, and the new scalp flap displayed slight depression but remained intact. The patient has declined from any further follow-up since.

BACKGROUND: The use of leeches can effectively increase the salvage rate of flap congestion. However, the first reaction from patients and carers in using leeches in clinical fields is strong aversion. This can be due to the fact that development of our culture from agriculture to industrial society, coming across leeches became fairly rare. Also because of the biological traits that leeches carry; staying attached to a leg or other body parts of the host, sucking blood, and leaving wounds. METHODS: This study was conducted through questionnaires, divided into many subgroups. We scaled the compliance of the two therapies, with or without leech. Maximum scale of 10 showing no rejective response to the therapy and minimum scale of 0 showing the greatest rejective response. RESULTS: Overall subjects' compliance was improved after explaining the benefits of hirudotherapy. Irrelevant to the explanation, there was no significant difference in general compliance between male and female. Young-aged group and medical personnel or people studying medicine showed higher compliance over older-aged group and the general public. CONCLUSION: In the terms of general social cognition, recognizing leech as a therapeutic material may not be welcomed at first, but provided with proper information and explanations, overall compliance of patients and carers can be improved and consequently result in superior outcomes in flap salvage.

BACKGROUND: The conventional cervicofacial flap may cause the aesthetic problem of sideburns with a mismatched shape and arrangement. We developed a modified method with the goals of minimizing the destruction of the shape and arrangement of the sideburns and minimizing complications in comparison with the conventional method. METHODS: The incision line was designed to descend just in front of the sideburns, without passing through them, and then to ascend with the sideburns posteriorly when a cervicofacial flap is performed, unlike the conventional method. Patients in whom this method was applied (group B) and patients who underwent surgery using the conventional method (group A) were investigated in a retrospective study. The method was evaluated by assessing changes in the arrangement of the sideburns and patients' satisfaction, and differences in the complication rate. RESULTS: In group A, 23 of the 31 patients experienced changes in the arrangement of their sideburns. Most patients who experienced a change in the arrangement of their sideburns were dissatisfied with the change. The patients in group B did not experience such changes, and the defects were well reconstructed. Most of them were satisfied with the final sideburn arrangement. CONCLUSION: A novel method was used to preserve the sideburns while performing a cervicofacial flap. As a result, the appearance of the sideburns was well preserved and the satisfaction of patients was also high. Moreover, this technique could also prove useful for reconstruction without any increase in complications compared to the conventional method.
