연구배경: 폐 랑게르한스세포 조직구증(pulmonary Lan gerhans cell histiocytosis, PLCH)은 랑게르한스세포의 증식으로 형성된 육아종이 여러 장기에 침범하여 발생하는 질환이다. 주로 폐에 침범하며, 무증상에서부터 호흡곤란등의 다양한 임상증상을 가진다. 국외뿐만 아니고 국내에서도 빈도가 적은 것으로 알려져 있어, 다기관에서 국내 증례를 모아 그 임상양상을 알아보고자 하였다. 방 법: 부위에 관계없이 조직학적으로 진단되고 폐의 병변이 있는 PLCH 환자의 임상증상을 ILD 연구회를 통하여 후향적으로 조사하였다. 결 과: 수집된 증례는 총 56명으로 남자 48명, 여자 8명이었고, 중간나이는 43세(18-67세)였다. 진단 당시 흡연자와 과거 흡연자는 79%로 흡연과 관계가 있었다. 가장 흔한 증상은 기침(39%)이었고, 이어 호흡곤란(38%), 객담(20%), 흉통(20%) 순이었다. 기흉은 16명의 환자에서 관찰되었다. 폐기능 검사에서 정상은 26명(61%), 제한성 7명(16%), 혼합형 7명(16%), 폐쇄성은 3명(7%)에서 관찰 되었다. 방사선 소견은 대부분의 환자에서 병변이 중엽과 상엽에 있었으며, 결절과 낭종이 같이 있는 경우가 59%로 가장 많았다. 결 론: 이 연구는 PLCH 환자에 대한 국가적 그리고 장기적 추적 연구의 필요성을 시사한다.

Germinoma is the most common type of intracranial germ cell tumors (GCTs). Pineal gland and suprasellar region are the most frequent sites of central nervous system (CNS) involvement. Intracranial masses caused by Langerhans cell histiocytosis (LCH) mimics features of CNS GCTs. LCH frequently involve spine and is the most common cause of vertebra plana in children. A 15-year-old boy presented with progressing symptoms of polydipsia, polyuria, general headache, nausea and severe back pain. Brain MRI showed brain tumor with simultaneous involvement of suprasellar region and pineal gland. An excisional biopsy of suprasellar mass was done. The pathologic assessment confirmed the diagnosis of germinoma. Patient's treatment continued accordingly. A spine MRI, done due to persistent backache, showed a vertebra plana. We reevaluated the primary diagnosis suspecting LCH. Germinoma of CNS was confirmed and a biopsy of vertebral lesion resulted in hemangioma. Thus we report a case of CNS germinoma with co-occurrence of vertebra plana. We emphasized the importance of histopathologic diagnosis of pineal/suprasellar masses and primary investigation of other CNS regions including spine for possible metastasis or comorbidities.

Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.

Erdheim-Chester disease (ECD) is a form of non-Langerhans cell histiocytosis that most commonly involves the skeletal system. We report an unusual case of ECD presenting as an anterior mediastinal tumor without skeletal involvement. A 60-year-old man with no remarkable medical history was referred for evaluation of a mediastinal mass. The patient underwent surgical excision of the tumor via video-assisted thoracoscopic surgery. Histologic examination revealed marked proliferation of atypical histiocytes with sclerosis, and the results of immunohistochemical staining were suggestive of ECD.

The present study reports a case of eosinophilic granuloma of the mandibular condyle. Eosinophilic granulomas on the mandibular condyle are very rare, but there are several common clinical and radiographic presentations. The clinical presentations involve swelling on preauricular area, limitation of opening, TMJ pain, etc. The radiographic presentations involve radiolucent lytic condylar lesion with or without pathologic fracture. Sometimes new bone formations are observed. The purpose of the article is to add new cases to the literatures.

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.
