한의학과 대체의학은 그 뛰어난 진단 기술 및 처방과 치료 효과에도 불구하고 선호도에 있어 서양의학에 많이 떨어지고 있는 것이 현 실정이다. 마찬가지로 한의학과 밀접히 연계되어 있는 대체의학도 그 효과에 대한 입증이 과학적으로 규명이 되지 못하고 있는 것이 가장 큰 단점으로 여겨진다. 본 논문에서는 대체의학에서 흔히 사용하는 이침 요법이 실제 인체 장기 기능 강화에 도움이 되는 행위인지를 생체신호를 분석하는 방법 중 얼굴의 피부색 변화를 살펴보는 망진 이론을 적용하여 이를 규명하는 방법을 제안하고자 한다. 이를 위해 폐 이혈 반사점을 자극한 후의 우측뺨 색상을 측정하여 자극 전과의 비교, 분석 실험을 수행하였다. 또한 검증과 규명을 위해 우선적으로 인체가 폐에 미치는 영향의 분석에 필요한 영상 분석 요소를 파악하였다. 실험 결과, 폐 이혈 반사점 자극에 의해 우측뺨의 a값과 b값이 증가하는 결과가 도출되었다.

Sialolithiasis is caused by the obstruction of a salivary gland or its excretory duct by the formation of calcareous concretions or sialoliths; this results in salivary ectasia and provokes subsequent dilation of the salivary gland. Sialolithiasis is relatively common, accounting for 30% of salivary diseases; however, it is rarely observed in childhood. This case report describes a 2-year-old male patient who complained of a painful swelling over the right cheek, and presented with palpable stones and pus discharge from the orifice of the right Stensen's duct. Computerized tomography of the neck confirmed the diagnosis, and the patient received intravenous empiric antibiotics combined with intraoral sialolithotomy. We also provide a review of the spectrum of concepts regarding the pathogenesis, diagnosis, and treatment of sialolithiasis.

Reported cases of a large dentigerous cyst involving the whole maxillary sinus are uncommon. A 22-year-old female patient suffering from swelling of the right infraorbital area and cheek with dull pain was referred to our department. Findings on computed tomography (CT) and magnetic resonance imaging (MRI) revealed a huge mass containing a displaced maxillary third molar involving the right maxillary sinus as a whole, with partial erosion of the posterior sinus cortical bone. Under general anesthesia, the mass was enucleated using the Caldwell-Luc approach, and, following histopathological analysis, was diagnosed as a dentigerous cyst. The case was followed for a period of seven years, and no evidence of sinus infection or recurring cyst formation was observed during that time.

About 20% of non-Hodgkin' lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer' ring. Malignant lymphoma arising in the parotid glands are relatively rare, although 90% of all salivary gland lymphomas, appear in parotid gland and are classified as extranodal non Hodgkin' lymphoma. We experienced one rare case of non-Hodgkin' lymphoma in the right parotid gland, with a painless swelling of the cheek region as the chief complaint. We treated with CHOP(cyclophosphamide, $750mg/m^2$ i.v. day1 ; doxorubicin, $50mg/m^2$ i.v. day 1 ; vincristine, $1.4mg/m^2$ i.v. day 1;prednisone, $50mg/m^2$ orally days 1 to 5. repeat every 21 days) and Rituximab combination therapy. We aimed to report here one case of non-Hodgkin' lymphoma in the right parotid gland with review of literature.

Sweet's syndrome is characterized by clinical symptoms, physical features, and pathologic findings which include fever, neutrophilia, tender erythematous skin lesions, and a diffuse infiltrate of mature neutrophils. This is a report of our experience of Sweet's syndrome with parotitis. A 57-year-old man initially presented with tender swelling on the right cheek similar to parotitis. His symptoms relapsed despite the use of an oral antibiotic agent for 3 weeks. He additionally presented with erythematous papules and plaques on the periocular area and dorsum of both hands. Histiopathologic findings on punch biopsy of the right dorsum of the hand showed superficial perivenular histiocytic infiltration without vasculitis. We confirmed this as histiocytoid Sweet's syndrome and used systemic corticosteroid. After initiation of treatment with systemic corticosteroids, there was a prompt recovery from both the dermatosis-releated symptoms and skin lesions. Sweet's syndrome should be considered in patients with therapy-refractory parotitis and unclear infiltrated nodules. We present a confusing case who initially appeared to have parotitis but turned out to have histiocytoid Sweet's syndrome.

Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

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.

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.

Parry-Romberg syndrome (PRS) is a rare, acquired disorder characterized by progressive unilateral facial atrophy of the skin, soft tissue, muscles, and underlying bony structures that may be preceded by cutaneous induration. It is sometimes accompanied by ipsilateral brain lesions and neurological symptoms. Here we present the case of a 10-year-old girl with right-sided PRS and recurrent monoplegic ataxia of the left leg. At 4 years of age, she presented with localized scleroderma over the right parietal region of her scalp; her face gradually became asymmetric as her right cheek atrophied. Brain magnetic resonance imaging revealed hemiatrophy of the face and skull base, and T2-weighted images showed increased signal in the right hemipons and hemicerebellar peduncle. Magnetic resonance angiography findings were unremarkable. She was treated with oral prednisolone, and her recurrent gait ataxia diminished within 2 months of the follow-up period. To the best of our knowledge, this is only the second case of PRS presenting with an abnormal involvement of the ipsilateral hemipons.
