Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-year-old male smoker presented with a painless lesion with a verrucous surface and erythematous spots on the hard palate. Excisional biopsy revealed oral mucosa consisting of hyperkeratosis, acanthosis, and elongated rete pegs. Subjacent connective tissue showed numerous foam cells with clear cytoplasm and pyknotic nucleus, negative on periodic acid-Schiff staining. Immunohistochemical analysis revealed foam cells positive for anti-CD68 antibody, while anti-KI-67 antibody was restricted to the basal layer of the oral epithelium. A final diagnosis of OVX was established. The patient showed no signs of recurrence after seven months of follow-up. Physical trauma and smoking habits can be directly related to the etiology of verruciform xanthoma because the lesion is chronic and inflammatory with slow growth, and sites if high trauma are more often affected by such a lesion. The hard palate is the second most commonly affected site, and local trauma caused by smoking can be a cause of this type of lesion.

Xanthoma disseminatum (XD) is a benign, non-Langerhans cell histiocytosis characterized by disseminated xanthomatous lesions with face, flexures, and mucosa. Most of XD develops in mucocutaneous lesions including skin, oral cavity and pharynx, however laryngeal involvement is uncommon. While the natural course of XD is usually benign and often self-limiting, but XD develop in critical anatomical locations may result in morbidity and mortality. Localized mucous lesions in oropharynx and larynx lead to dysphagia, dyspnea and air way obstruction. The diagnosis of XD was based on clinical, histological and immunohistochemical findings. The treatment is complex and non-consensual. Local treatment with cryotherapy, radiotherapy, surgery, and carbon dioxide lasers have been attempted with various results. Systemic medication with peroxisome proliferator-activated gamma receptors, statins, fenofibrate, chlorodeoxyadenosine, cyclophosphamide, doxycycline, and cyclosporine have also been reported, but none have proven particularly successful. A 59-year-old man presented with respiratory symptoms because of laryngeal involvement of XD. We had to remove the obstructive lesion for relieving the symptoms. We experienced XD in Larynx that was rare in otorhinolaryngology. So we report this case with review of literatures.

A 2-year-old, 12.5 kg, castrated male, mixed-breed dog was presented with a 1-year history of pruritus and progressive alopecia. On physical examination, no remarkable findings were detected including body condition score (5/9). A dermatological examination of the dog revealed generalized erythema, papules or plaques, especially on the face, auricle, dorsum, and shoulder. A fine-needle aspiration of the dorsum and face lesions revealed various numbers of macrophages with foamy cytoplasm and multinucleated giant cells. A bacterial culture test showed the growth of Staphylococcus pseudintermedius. A complete blood cell count was unremarkable and biochemical abnormalities included hyperglobulinemia (4.8 g/dL, reference interval 2.5-4.5 g/dL), mild hypertriglyceridemia (277 mg/dL, reference interval 10-100 mg/dL) and mild hypercholesterolemia (383 mg/dL, reference interval 110-320 mg/dL). Additional diagnostic tests were performed to identify the underlying cause of hyperlipidemia. Canine pancreatic lipase immunoreactivity (<50 ng/mL, reference interval 0-200 ng/mL) and total T4 (1.4 ㎍/dL, reference interval 1.1-5.6 ㎍/dL) were within the reference intervals. For a definitive diagnosis, skin biopsy specimen was collected from the papular lesions on the dorsum by using a 4 mm biopsy punch. A histopathological examination revealed numerous large macrophages with abundant foamy cytoplasm in the dermis. The foamy macrophages were located diffusely between the collagen fibers. Extracellular amorphous lipid deposits were also presented in the dermal tissue. A definitive diagnosis of cutaneous xanthoma was made based on clinical signs and cytological and histopathological results.

Sclerosing hemangiomas of the lung are uncommon benign tumors. Although their histologic appearances are distinct and well-defined, their histogenesis is uncertain. Liebow and Hubbell reported seven cases of unusual pulmonary lesions which they named sclerosing hemangiomas in 1856. Similar cases had previously been reported under different names: Xanthoma, pulmonary histiocytoma, Xanthofibroma. We have experienced 3 cases of sclerosing hemangioma of lung at the Department of Thoracic and Cardiovascular Surgery, Yonsei University, college of Medicine, Seoul, Korea during a period of December 1985 through September 1988. This report is an early result of surgical treatment of three patients with pulmonary sclerosing hemangioma and their pathologic findings.

Allagille 증후군은 담즙분비의 감소로 인한 간의 손상, 황달, 황색종, 소양증 등의 다양한 문제들을 가진다. 구강영역의 문제점으로는 출혈 및 감염, 치아의 변색을 들 수 있다. 또한 증례의 환아와 같이 간이식을 할 경우 지속적인 면역억제제의 사용으로 인한 감염의 위험성은 평생 동안 계속되게 된다. 따라서, Alagille 증후군 환자에 있어서는 다음과 같은 사항들이 치과치료에서 필요하다고 생각된다. 의과 및 치과병력을 정확히 파악하고, 내원마다 전 치아들에 대한 평가를 철저히 실시하며, 발견되는 우식은 더 이상 진행이 되지않도록 즉시 치료해야 한다. 예방적 항생제를 투여하더라도 감염과 출혈을 예방하기위해 치료 시 최소한의 외상이 가해지도록 하며, 치료 후에도 감염의 소지가 있을 수 있는 치아는 제거하는 편이 유리하다. 성장이 끝난 후에는 심미적 기능적인 문제를 해결하기 위해 전 치열에 대한 재건이 필요하며 환자 스스로 구강위생에 신경을 쓸 수 있도록 예방 교육에 힘써야 할 것으로 생각한다.

Background: Xanthelasma palpebrarum (XP) is a benign periorbital lesion. The relationship between xanthelasma lesion size and serum cholesterol levels has been poorly studied. In this study, we investigated this relationship in the context of the clinical etiology of XP. Methods: We retrospectively reviewed medical records and pathology reports of all patients treated for XP at our hospital between June 2014 and June 2021; the data were used to analyze lesion size, underlying disease, serum cholesterol, and disease recurrence. Results: The mean values for patient age, serum cholesterol, and lesion size were 53.0 years, 235.0 mg/dL, and 69.2 mm², respectively. XP mainly occurred in women (64.7%); furthermore, the incidence of XP and lesion size was greatest among patients in their 5th decade of life (41.2%). There was no statistically significant relationship between xanthelasma lesion size and serum cholesterol level. Conclusion: This study compared lesion size with various clinical features in XP patients. In patients who underwent surgery for XP, serum cholesterol levels tended to be higher than those in the general population. However, the trend between the size of XP and serum cholesterol level was unclear. Therefore, if a patient with XP visits the hospital for surgery, it is recommended to check the lipid profile to confirm underlying dyslipidemia regardless of the size.

지방경화성 점액섬유종은 섬유골을 형성하는 양성 골질환으로 대퇴골 원위부의 전자간 부위에서 주로 발생한다. 이 질환은 지방종, 지방황색종, 점액종, 지방섬유종, 섬유형성이상 유사 병변, 낭의 형성, 지방괴사, 허혈성 골화 또는 연골 형성 등 다양한 조직학적 소견이 뒤섞여 있는 특징을 보인다. 비록 일부에서는 지방경화성 점액섬유종을 섬유형성이상이나 골내 지방종 또는 기타 다른 양성 병변의 한 변형으로 생각하기도 하지만, 최근에는 지방경화성 점액섬유종을 하나의 독립된 질환으로 인식하려는 경향이 강하다. 저자들은 48세 여자 환자의 대퇴골 전자간 부위에서 지방경화성 점액섬유종의 전형적인 방사선학적 그리고 조직학적 소견을 보이는 증례를 경험하였다. 방사선학적으로 이 병변은 방사선 투과성 및 젖빛 유리와 같은 특성을 보였고 주변은 경화성 골조직으로 싸여 있었다. 조직학적으로는 점액조직, 지방종 그리고 섬유형성이상 유사 조직이 주류를 이루었다.

목적: 아킬레스건의 황색종은 드물게 발생하며 증상이 심할 경우 수술적 치료가 필요한 경우가 있다. 전 절제술 후 재건술은 높은 수술의 숙련도를 요하며 다양한 합병증에 대한 우려가 있다. 본 연구에서는 양측 아킬레스건에 발생한 거대 황색종에 대해 자가 아킬레스건을 보존하는 쐐기형 절제술 후 추시 결과를 분석하고자 하였다. 대상 및 방법: 2010년 7월부터 2018년 5월까지 양측 아킬레스건에 발생한 황색종 환자 5명에 대해 자가 아킬레스건을 보존하는 쐐기형 절제술을 시행하였다. 평균 나이는 49세(범위, 40-55세)였고 추시 기간은 평균 21.4개월(범위, 12-31개월), 남자는 3명, 여자는 2명이었다. 수술 후 발생한 합병증을 기록하였으며 족관절 운동 범위, American Orthopaedic Foot & Ankle Society(AOFAS) ankle/hindfoot score, 치료 만족도 시각적 척도(visual analogue scale for overall satisfaction), single-limb heel raise 가능 여부, 그리고 직장으로의 복귀 시간을 측정하여 수술 후 임상적인 평가를 시행하였다. 결과: 1명에서 열개창(wound dehiscence)이 발생하였으며 추가적인 수술적 치료 없이 호전되었다. 마지막 추시에서 모든 환자들의 족관절의 운동 범위는 정상이었으며 AOFAS ankle/hindfoot score는 평균 91점(범위, 85-96점)이었고 치료 만족도 시각적 척도는 8-10점의 분포를 보였다. 직장으로의 복귀는 평균 27.6일(범위, 17-58일)이었으며 모든 환자는 single-limb heel raise가 가능하였다. 결론: 아킬레스건에 황색종이 발생하였을 경우 자가 아킬레스건을 보존하며 시행하는 쐐기형 절제술은 좋은 수술적 치료가 될 수 있을 것으로 판단된다.
