Abstract
BACKGROUND: Pulmonary epithelial-myoepithelial carcinoma is a very rare type of salivary gland lung tumor. No standard treatment plan yet. This article intends to analyze the clinical characteristics of pulmonary epithelial-myoepithelial carcinoma and discuss the diagnosis and treatment of pulmonary epithelial-myoepithelial carcinoma.Entities:

1左下肺病变影像学表现及纤维支气管镜检查图像,A:CT平扫提示左肺下叶见一软组织密度肿块影,边界欠清,肿物最大层面大小约5.4 cm×4.3 cm; B:PET/CT提示肺门区局灶性放射性摄取增高,SUVmax值为13.7,SUVmin值为0.4,平均值3.2,肿块大小约2.1 cm×1.8 cm,双侧肺门及纵隔未见肿大淋巴结。C:PET/CT显示头颅、颈部、腹部脏器、四肢等未见放射性摄取异常增高灶; D:纤支镜提示左肺下叶基底段支气管见新生物,外表光滑,见少量脓性分泌物,支气管远端阻塞
Imaging findings and fibrobronchoscopy images of the tumor tissue in left lower. A: CT scan showed a soft tissue density mass in the lower lobe of the left lung, the border was unclear, the maximum size of the mass was about 5.4 cm×4.3 cm; B: PET/CT showed an increased focal radioactive tissue uptake in the hilar area, SUVmax was 13.7, SUVmin was 0.4, MEAN was 3.2, mass size was about 2.1 cm×1.8 cm, and no swelling lymph nodes were found in bilateral hilar and mediastinum. C: PET / CT showed no abnormal and increased radioactive tissue in the skull, neck, abdominal organs, limbs, etc; D: fibrobronchoscopy showed that new organisms were found in basal segment bronchus of the left lung, with a smooth appearance and a small amount of purulent secretion, the distal bronchus is blocked
2肿瘤组织免疫组化染色,A:(HE染色法,×400)可见上皮细胞和肌上皮细胞的构成腺管双层结构,核异型性不明显,胞质透亮; B:(Ki-67, ×400)散在热点,约10%;C:(PAS, ×400)肌上皮细胞PAS染色呈阴性; D:(S-100, ×400)肌上皮细胞S-100染色呈阳性; E:(SMA, ×400)肌上皮细胞SMA染色呈局灶阳性; F:(TTF-1, ×400)肌上皮细胞及上皮细胞TTF-1染色均为阴性; G:(CK, ×400)上皮细胞CK染色呈阳性; H:(AB, ×400)上皮细胞AB染色呈阳性。I:(PD-L1, ×100)PD-L1蛋白表达为阴性
immunohistochemical of tumor tissue. A: the epithelial cells and myoepithelial cells constitute a bilayer structure of the glandular duct, the nuclear heteromorphism is not obvious, and the cytoplasm is translucent (Haematoxylin and eosin staining, ×400); B: scattered in hot spots, about 10% (Ki-67, ×400); C: myoepithelial cells were negative for PAS staining (PAS, ×400); D: myoepithelial cells were positive for S-100 staining (S-100, ×400); E: myoepithelial cells SMA staining was focally positive (SMA, ×400); F: myoepithelial cells and epithelial cells were negative for TTF-1 staining (TTF-1, ×400); G: epithelial cells were positive for CK staining (CK, ×400); H: epithelial cells AB staining was positive (AB, ×400). I: PD-L1 protein expression was negative (PD-L1, ×400)
