Introduction. Mucoepidermoid carcinoma (MEC) of the lung is a rare form of lung cancer that is classified into low grade and high grade based on histological features. Surgical resection is the primary treatment for low-grade MEC with excellent outcomes, while high-grade MEC is a more aggressive form of malignancy.Clinical Case. We report a case of a 46-year-old woman who presented with dyspnea on exertion. Imaging studies revealed a mass involving the right upper lobe bronchus. Bronchoscopy, surgical resection, and pathological examination revealed a low-grade MEC with tumor-free margins. No adjuvant treatment was given.Discussion. Primary pulmonary MEC is a rare type of lung cancer with only few reported cases. This patient illustrates a typical presentation for low-grade MEC wherein surgical resection is considered curative. In contrast, high-grade MEC is a more aggressive malignancy with a poorer outcome. The role of targeted therapy directed against EGFR or a novel CRTC1-MAML2 fusion protein expressed in some high-grade tumors is yet to be determined.

AbsztraktBevezetés:A daganatos haláloki statisztikát vezető malignus hörgőtumorok eseteiben hosszú túlélésre csak a radikálisan operált betegek számíthatnak. Mégis, jól lokalizált, centrális és low grade malignomák kezelésében a tüdőmegtartó centrális bronchusplasztikáknak is helye lehet.Célkitűzés:A parenchymakonzerváló műtétek az egyik oldali teljes tüdő eltávolításának vagy az inoperabilitásnak a pozitív alternatívái lehetnek. Értékét a mortalitás, a szövődmények és a túlélés alapján lehet megítélni.Beteganyag és módszer:1985–2012 között 7130 hörgőcarcinomás beteget operáltunk. 80 centrális bronchoplasztikai műtétből7 esetben a jobb vagy bal főhörgő izolált vagy az egész bifurcatiós carina resectiója és a tüdő autotranszplantációja révén teljes tüdőmegtartást értünk el.A 4 nő és 3 férfi átlagéletkora 28,5 (14–58) év volt. 4 beteg carcinoid, 1 laphámrák, 1 mucoepidermoid carcinoma miatt, 1 beteg kissejtes tüdőrák (SCLC) miatti kemo-radioterápia (KRT) után került műtétre. 1 esetben izolált carina-, 1 betegnél balfőhörgő-, 5 betegnél jobbfőhörgő-resectio történt. Az anastomosist csomós PDS öltésekkel a műtéti területen át bevezetett steril tubus (6 beteg), illetve jet-katéter (1 beteg) felett varrtuk. A betegeket műtét után extubáltuk.Eredmények:Műtéti mortalitás nem volt. A korai posztoperatív szakban ismételt bronchoscopos leszívásokat alkalmaztunk. A SCLC miatt operált betegnél subacut anastomosisstenosis miatt kétoldali ideiglenes stentimplantációt alkalmaztunk. 174 hónapja él, Karnofsky-index 90%. 5 másik beteg is tumorrecidíva, metastasis nélkül él. A laphámrák miatti izolált jobbfőhörgő-resecált beteg 83 hónap után bal oldali disseminált kissejtes tüdőrák miatt exitált.Átlagos túlélés: 118 hónap (7–233).Következtetések:Fiatal betegeknél, lokalizált centrális főhörgő rosszindulatú daganatok szelektált eseteiben, izolált carina-főhörgő resectióval nemcsak teljes tüdőmegtartás, hanem hosszú túlélés is elérhető. Az irodalomban vannak hasonlóan sikeres, kisebb szériák és esetbemutatások (összes esetszám 200 alatt), de hosszú távú eredményekről kevés az adat. Hazánkban ez a legnagyobb széria, eredményeink nemzetközi kitekintéssel mérve is helytállóak.

Aims: To investigate the efficacy and safety of minimally invasive bronchoscopic interventions for patients with tracheobronchial mucoepidermoid carcinoma (MEC). Methods: Patients with tracheobronchial MEC were included in this retrospective study, and the clinical features, histologic grading, treatments, and cumulative survival rates were calculated. Patients were categorized into child (n = 16) and adult (n = 19) group according to their ages. Histologic grading, treatments, and survival status were compared between the two groups. Results: In pathology, high-grade MEC counts for 6.77% and 42.10% in the child and adult group, respectively. As tumor growth pattern was concerned, 93.33% and 21.05% tumors in the child and adult group present intratracheal type. Multiple bronchoscopic interventions were conducted, including rigid bronchoscopy, argon plasma coagulation (APC), dioxide carbon cryotherapy, and electric loop. Tumors could be removed by multiple bronchoscopic interventions. Bronchoscopy-associated complications were rare, including an oral mucosa injury and a glottis edema. In the child group, one patient underwent left upper lung lobectomy. In the adult group, lobectomy and/or chemotherapy and/or radiotherapy were conducted in seven patients. The 5-year survival rate was 100% and 68.90% in the child and the adult group, respectively. Conclusions: Almost all children have low-grade and intratracheal MEC; 2/5 adults have invasive high-grade MEC. Multiple bronchoscopic interventions are effective in erasing low-grade intratracheal MEC without severe complications. For high-grade invasive MEC, aggressive and comprehensive therapy should be considered.

A 65-year-old with non-small cell lung cancer developed autoimmune haemolytic anaemia while receiving pembrolizumab containing chemoimmunotherapy. Initially thought to be due to pembrolizumab induced haemolysis, he was treated with steroids, and pembrolizumab was held. Haemolysis was refractory to steroids and blood was observed to agglutinate in cold room temperatures. Cold agglutinins in high titre and monoclonal serum IgM kappa protein were detected. Bone marrow biopsy showed marginal zone lymphoma confirming low grade B-cell lymphoma causing cold agglutinin disease. B-cell depletion by rituximab stopped haemolysis, and pembrolizumab was safely continued for lung cancer.

Mucoepidermoid carcinoma (MEC) of the lung is an extremely rare tumor, and a standard chemotherapy has not been established. Furthermore, little work has been conducted on the genetic characteristics of MEC. We herein report the case of a 42-year-old nonsmoking male patient who was referred to our hospital due to cough. Chest computed tomography demonstrated infiltration and atelectasis in the right lower lobe. He was eventually diagnosed with non-small cell lung cancer (NSCLC) with MEC differentiation corresponding to clinical stage IVA (cT4N2M1a[PLE]). Genetic testing for EGFR mutations was negative, but positive for anaplastic lymphoma kinase (ALK) fusion gene. After 2 weeks of first-line treatment with alectinib, the tumor decreased in size and his symptoms improved. Advanced MEC is a rare tumor, and reports on the treatment of ALK-positive NSCLC with MEC differentiation are rare.
