Thirteen cases of primary thymic carcinomas are described. The patients' ages ranged from 19 to 64 years, with a median of 40 years. Nine of them were male. Chest pain with or without cough was the main presenting symptom. No patient had myasthenia gravis. Five histological types were identified; two were undifferentiated (lymphoepithelioma-like) carcinoma, one was a clear-cell carcinoma, two were mixed squamous and small-cell carcinoma, and six were squamous cell carcinoma. All the tumors were variably positive for anti-keratin antibody AE1 and AE3, but negative for AE2. Anti-neuron specific enolase antibody was useful in identifying and confirming the small-cell carcinoma component of the mixed carcinomas. Anti-epithelial membrane antigen antibody aided in revealing the glandular structures in mixed adenosquamous and small-cell carcinomas. Thymic carcinomas were histopathologically differentiated from thymomas by their malignant cytological appearance, increased mitotic activity, and central tumor necrosis. All six patients with pure squamous-cell carcinoma were still alive, with a median survival time of 27 months. All but one of the other patients of different histological types died, the exception being a recent case of mixed adenosquamous and small-cell carcinoma; their median survival was 19.5 months, or 18 months when the latter surviving case is included. The prognosis of patients with pure squamous-cell carcinoma was better.

Nineteen cases of thymic carcinoma treated in our hospital (mean age 60.0 years, seven males and twelve females) were studied clinically. Thirteen cases (68.4%) had subjective symptom; for example, chest pain, face edema or cough. Two cases (10.5%) had the associated diseases; one had gammaglobulinemia, the other one had Cushing syndrome and hypogammaglobulinemia. The histological subtypes were eleven squamous cell carcinomas (SCC) (57.9%), three undifferentiated carcinomas, two small cell carcinomas, one papillary adenocarcinoma and one lymphoepithelioma-like carcinoma. The 5 year survival rate of all cases was 42.7%. The 10 years survival rate was 21.4%. The median survival time was 56.1 months. There were one Stage I case, nine stage III cases, four stage IVa cases and five stage IVb cases. More than stage III cases were eighteen (94.7%). Five cases of stage IVb were T2N1M0, T3N1M0, T3N0M1 and T4N0M1. The 5 year survival rate of SCC was 65.6%, and that of the other subtypes was 14.3%. The cases resected completely were only eight cases (42.1%), and the 5 year survival rate of these was 70.0%. On the other hand, the rate of five cases resected incompletely was 53.3%. Metastasis occurred in 12 cases (63.2%). Metastasis occurred frequently in pleura, lymphnode, lung, bone and liver. The radiotherapy for SCC was effective and the 5 year survival rate was 83.3%. Furthermore, there were some long survivors in the cases undergone incomplete resections by postoperative radiotherapy jointly. On the other hand, the chemotherapy was not effective in our series. However, it was reported recently that the regimen including cisplatin was effective. So it was impressed that the combined therapy including surgery radiotherapy and induction chemotherapy would be important to obtain better results.

The present report describes a case of lymphoepithelioma-like carcinoma (LELC) of the lung and presents immunohistochemical and in situ hybridization (ISH) studies of the tumor. A 39-year-old Chinese woman, who was born in China and emigrated to Japan at the age of 29, suffered from a cough for 2 years and received a middle and lower lobectomy with mediastinal lymph node dissection after induction chemotherapy. The tumor consisted of undifferentiated carcinoma and areas of more differentiated squamous cell carcinoma with an intense lymphoid infiltrate. Serological studies and ISH studies showed EBV infection of the tumor. The immunophenotype of tumor-infiltrating T-lymphocytes (TITL) of the present case was examined immunohistochemically and was compared with that of an LELC case reported previously. Most CD3-positive T cells of TITL in both cases were labeled with both CD8 and TIA-1 but not with granzyme-B, indicating the TITL to be cytotoxic T lymphocytes (CTL) in the resting state. The lack of CTL activation at the tumor site might have been due to local inhibition of EBV-specific CTL responses such as T-cell anergy. Because the EBV-specific CTL derived from peripheral blood lymphocytes, in contrast to the TITL, may not be influenced by either tumor-produced suppressor factors or negative regulatory T cells, they may inhibit the hematogenous metastasis of EBV-positive LELC, possibly resulting in a better prognosis. Because LELC of the lung responded to preoperative chemotherapy in the present study, it may be useful for reducing the local tumor burden and facilitate subsequent local therapy, although the mechanism of chemosensitivity of LELC remains unknown.

A 31-yr-old Chinese female, a nonsmoker, presented with digital clubbing and coughing. Diagnostic evaluation revealed a pulmonary sequestration in the left lower lobe. During surgery a tumour was discovered, which turned out to be a lymphoepithelioma-like carcinoma. These tumours are mainly found in Asians, and are associated with the Epstein Barr virus and not with smoking. They are thought to have a better prognosis and to be more chemosensitive. The need for surgical treatment of pulmonary sequestration and the recognition of lymphoepithelioma-like carcinoma as a distinct clinicopathological entity is emphasized.

A 57-year-old Caucasian woman presented with nonproductive cough. Computed tomography revealed a peripheral solid mass in the upper lobe of the left lung. She underwent thoracotomy and upper lobectomy. Histology of the excised tumor demonstrated lymphoepithelioma-like carcinoma of the lung, with no associated Epstein-Barr virus activity. Being a rare entity and mostly seen in Asians, very few cases have been described previously.

Primary pulmonary lymphoepithelioma-like carcinomas are extremely rare tumors with better prognosis than other types of non-small cell lung cancer. An 83-year-old man presented with cough and hemoptysis for 2 weeks. Chest CT images showed a cylinder-shaped lesion in the right upper lung. F-FDG PET/CT showed strong FDG uptake (SUVmax, 34.5) of the tumor with ipsilateral hilar lymph node metastases. Video-assisted thoracoscopic lobectomy was performed. Histopathologically, the tumor was composed of epithelial tumor cells with high proliferation index (80%) and abundant lymphoplasmacytic cells, consistent with lymphoepithelioma-like carcinoma.

We report a rare case of collision of lymphoepithelioma-like carcinoma (LELC) and adenocarcinoma (AC) in the lung. A 59-year-old woman had a history of fever and cough. A mass was found by X-ray in the left upper lung. Magnetic resonance imaging (MRI) shows a dumbbell-like mass in the fore and tongue segment of the left upper lung with irregular spiculate margin. Positron emission tomography/computed tomography (PET/CT) (18F-FDG) shows strong concentration of radioactivity (SUVmax 6.9-12.3 cm) in the lung mass only. The patient subsequently underwent resection of left upper lung and associated hilar lymph nodes. Histological examination revealed it was a collision carcinoma comprising LELC and AC. The hilar lymph nodes were tumuor free. The immunoreactions, Epstein-Barr early RNA in situ hybridization and molecular analyses, such as EGFR mutation, c-Met, anaplastic lymphoma kinase were different in both tumuor components, indicating they derived from different cell origin. This rare case was discussed.

Lymphoepithelioma-like carcinoma, a large cell carcinoma with pronounced lymphocyte infiltration, is a rare entity mostly seen in the nasopharynx. But primary pulmonary LELC in children & adolescents is extremely rare. Here we present a 13 year old girl with chief complaint of fever, cough, shortness of breath and heaviness in the left side of chest. She underwent left upper lobectomy. Histopathological examination of the biopsy specimen confirmed it to be a case of large cell carcinoma of lung, lymphoepithelioma type, invading pleura (stage pT3N0M0) with high serum titre of anti Epstein-Barr virus IgG antibody.
