Abstract
BACKGROUND Large cell neuroendocrine carcinoma (LCNEC) of the endometrium is an uncommon and highly aggressive tumor that has not been comprehensively characterized. We report a case of pure endometrial LCNEC and review the current literature of similar cases to raise awareness of the histological features, treatment, and prognosis of this tumor.
CASE SUMMARY We report the case of a 73-year-old woman who presented with irregular postmenopausal vaginal bleeding. Ultrasonography showed an enlarged uterus and a 5.1 cm × 3.3 cm area of medium and low echogenicity in the uterine cavity. Biopsy by dilatation and curettage suggested poorly differentiated carcinoma. Magnetic resonance imaging revealed a heterogeneously enhanced uterine tumor with diffuse infiltration of the posterior wall of the uterine myometrium and enlarged pelvic lymph nodes. The patient underwent a hysterectomy and bilateral adnexal resection. Gross observation revealed an ill-defined white solid mass of the posterior wall of the uterus infiltrating into the serosa with multiple solid nodules on the serous surface. Microscopically, the tumor cells showed neuroendocrine morphology (organoid nesting). Immunohistochemistry revealed the tumor cells were diffusely positive for the neuroendocrine markers CD56, chromogranin A, and synaptophysin. Thus, the tumor was diagnosed as stage IIIC endometrial LCNEC.
CONCLUSION Pathologic findings and immunohistochemistry are essential in making a diagnosis of endometrial LCNEC.

Abstract
Large-cell neuroendocrine carcinoma (LCNEC) of the endometrium is an extremely rare, high-grade malignant tumor. We herein report a case of a rapidly growing LCNEC arising in the endometrium. A 52-year-old woman was referred to Toyooka Hospital (Tooyoka, Japan) due to genital bleeding in February 2016. There had been no abnormalities on a regular gynecological and physical examination 3 months prior to the consultation. Imaging (computed tomography and magnetic resonance imaging) and a pelvic examination revealed a tumor sized 16.9×8.4×7.8 mm occupying the intrauterine cavity and extending into the vaginal cavity. Multiple metastatic pelvic and paraaortic lymph nodes were also identified. Continuous bleeding from the tumor was observed, and a blood examination revealed anemia, which was likely due to that bleeding. Biopsy of the tumor was performed, and large atypical cells were identified. The tumor cells were negative for cytokeratin AE1/AE3 and chromogranin A, but positive for CD56 and synaptophysin. There was also an abundance of Ki-67-positive cells in the tumor, altogether suggesting that the tumor was an LCNEC. The patient succumbed to the disease 36 days after the first consultation. Based on the findings of the present case and previously published cases, LCNECs arising in the endometrium may progress rapidly and are associated with an unfavourable outcome. LCNEC should be included in the differential diagnosis in cases of rapidly growing tumors of the uterine corpus.

Metastatic large cell neuroendocrine carcinoma of the lung arising from the uterus: A pitfall in lung cancer diagnosis. Pathol Res Pract 2016; 212:654-7. [PMID: 27113439 DOI: 10.1016/j.prp.2016.03.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2015] [Revised: 03/02/2016] [Accepted: 03/21/2016] [Indexed: 12/29/2022]
Abstract
A 41-year-old female smoker presented with a vaginal mass. Gynecological examination showed a mass filling the uterine corpus, cervix, and vagina. A total abdominal hysterectomy was performed. Macroscopic findings included a large fragile mass involving the uterine cavity, cervix, and vagina. Histology revealed atypical ducts admixed with solid components consisting of large atypical cells. The initial pathological diagnosis was grade 3 endometrioid adenocarcinoma. The patient was designated as stage II according to the 2008 International Federation of Gynecology and Obstetrics (FIGO) staging. Two years later, two nodules were found in the upper lobe of the left lung, and the patient underwent an upper lobectomy. The masses, which exhibited solid and organoid growth patterns of large atypical cells, had histological characteristics of large cell neuroendocrine carcinoma (LCNEC) of the lung. However, the tumor was immunohistochemically positive for neuroendocrine markers, such as synaptophysin in addition to estrogen receptor and progesterone receptor, and the tumor was negative for thyroid transcription factor-1. These immunohistochemical results were almost identical to those of the solid portions of the uterine carcinoma. The final diagnosis was LCNEC combined with endometrioid adenocarcinoma of the uterine corpus and lung metastasis of the LCNEC component of the endometrial carcinoma. LCNEC often arises in the lung, but it rarely arises in other organs. Some patients with metastatic components exhibited only a LCNEC pattern although the primary tumor was a mixed carcinoma consisting of LCNEC and other histology, like the present case. LCNEC is often poorly differentiated, especially in extrapulmonary primary organ LCNEC. Therefore, pathologists should consider metastatic carcinoma when they encounter lung LCNEC in a patient with a preceding extrapulmonary carcinoma composed of a poorly differentiated component or LCNEC component, and they should clarify tumor immunohistochemical characteristics to confirm the diagnosis.

Abstract
Sarcoidosis as a distinct disease entity was diagnosed more than 100 years ago. The signs and symptoms of the disease are nonspecific, posing a challenge for early and accurate diagnosis. IgG4 disease or syndrome has various clinical manifestations, such as sclerosing pancreatitis, sclerosing cholangitis, prostatitis, tubulointerstitial nephritis, interstitial pneumonia, and enlargement of salivary glands. This article discusses the role of the different diagnostic imaging modalities in sarcoidosis and IgG4 disease, including radiographs, computed tomography, magnetic resonance imaging, and conventional nuclear medicine, with a special emphasis on positron emission tomography as a superior modality for assessing these inflammatory diseases.
