SPONTAN REGRESYON İZLENEN LANGERHANS HÜCRELİ HİSTİYOSİTOSİZ: OLGU SUNUMU

Pulmoner eozinofilik granülom olarak da bilinen Langerhans hücreli histiyositoz, pulmoner Histiyositoz-X sendromuna ait bir interstisyel akciğer hastalığıdır. Genç sigara içen hastalarda daha sık görülmektedir. Tanı klinik ve tipik radyolojik bulgularla konulabilse de esas tanı patolojik incelemeyle konulur. Tedavinin temelini sigarayı bıraktırma oluşturur. Beş aydır eforla artan nefes darlığı yakınması ile polikliniğimize başvuran 39 yaşında bayan hastanın 15 yıl bir paket/gün sigara içme öyküsü mevcuttu. Yüksek rezolüsyonlu toraks bilgisayarlı tomografisinde her iki akciğer parankim alanlarında üst ve orta zonlarda daha belirgin, alt zonlarda daha hafif ve küçük, kaviter ve kistik nodüler lezyonlar mevcuttu. Bronkoalveolar lavaj sıvısının immünohistokimyasal boyamasında S100 yüzey antijeni pozitifliği gösteren Langerhans hücreleri görüldü. Sadece akciğer tutulumu olan ve sigaranın bırakılması ile lezyonlarında gerileme görülen olgumuzu sunmayı uygun bulduk

SPONTANEOUS REMISSION IN LANGERHANS CELL HISTIOCYTOSIS: A CASE REPORT

Langerhans Cell Histiocytosis, also known as pulmonary eosinophilic granuloma, is a part of the pulmonary histiyositozis-X syndrome and is a form of interstitial lung disease. It is common among young smoker patients. Although the diagnosis is based on the clinical and typical radiological findings, pathological examination is necessary for final diagnosis. Smoking cessation is main stay of treatment. A 39-year-old female patient referred to our clinic with the complaint of dispne for the last five months. She is a current smoker and had a smoking history of 15 packedyear. In high resolution computed tomography, cystic-cavitary appearances markedly in upper lobes were observed. Bronchoalveolar lavage showed some Langerhans cells with S-100 antigen positivity. We report a case of eosinophilic granuloma in whom spontaneous disease regression was obtained with only smoking cessation
