Abstract
Somatic endometrial carcinomas with trophoblastic components have only rarely been described. To better characterize this distinctive combination of histotypes, we report herein 4 new cases, representing the largest cohort reported thus far, and review previously reported cases. The 4 new patients ranged in age from 61 to 77 yr (mean, 68 yr). The first patient had a grade 2 endometrioid carcinoma, surgical International Federation of Gynecology and Obstetrics stage IA, that recurred 5 months later at the vaginal apex with purely choriocarcinoma elements, suggestive of unsampled trophoblastic areas in the uterus. The 3 other patients were all International Federation of Gynecology and Obstetrics stage III, and included 2 cases of dedifferentiated endometrial carcinoma with 40% and 20% choriocarcinoma components, and 1 case of grade 1 endometrioid carcinoma with a 40% choriocarcinoma component. Postoperative serum β-human chorionic gonadotropin was elevated in all patients. All received adjuvant combination chemotherapy, but all were dead of disease with distant metastases at an average of 11.75 mo (range, 7-16 mo) after primary staging. Data from our cases were combined with those from 24 cases that had previously been reported in the literature between 1972 and 2016. Analysis of this combined data indicates that endometrial carcinoma with trophoblastic component is a rare neoplasm that occurs primarily in postmenopausal patients. The trophoblastic component is most commonly a choriocarcinoma and the somatic component is most commonly an endometrioid carcinoma or an adenocarcinoma/carcinoma reported without further specification; the somatic component may be a diverse array of histotypes or histotype admixtures. Serum and/or urine β-human chorionic gonadotropin is elevated in almost all patients, and fluctuations of β-human chorionic gonadotropin generally correlated with tumor relapses or recurrences. The stage distribution and patient outcomes in the current and previously reported patients suggests that trophoblastic differentiation usually, but not invariably denotes clinical aggressiveness.

Abstract
Giant cell tumors, a well-recognized neoplasm of bone, can rarely be found in the uterus. Such tumors are characterized by a dual population of mononuclear and osteoclast-like giant cells that lack epithelial and specific mesenchymal differentiation. In this study, the clinicopathologic features of 3 giant cell tumors of the uterus were reviewed. Immunohistochemistry for CD68, CD163, h-caldesmon, desmin, SMA, AE1/AE3, CD10, ER, PR, cyclin D1, CD1a, CD34, CD30, S100, myogenin/myoglobin, and Ki-67 was performed in all tumors, along with ultrastructural analysis in one. The patients were 47, 57, and 59 yr and the tumors measured 2.5, 7.5, and 16.0 cm. One neoplasm was confined to the endometrium, whereas the other 2 were myometrial. All 3 tumors showed a nodular growth comprised of mononuclear and osteoclast-like giant cells. The endometrial-confined tumor consisted of histologically benign mononuclear cells, whereas the others exhibited marked atypia. Mitotic activity was up to 5/10 HPF in the benign tumor and up to 22/10 HPF in the malignant. No cytologic atypia or mitoses were observed in the giant cells. CD68 and CD10 were strongly and diffusely expressed in both components of 3 and 2 neoplasms, respectively. Cyclin D1 was focal in the mononuclear cells and focal to diffuse in the giant cells. CD163 was diffuse in the mononuclear cells, but absent to focal in the giant cells. Ultrastructural analysis lacked diagnostic features of epithelial or specific mesenchymal differentiation. Both malignant tumors demonstrated an aggressive behavior. In summary, although rare, giant cell tumor of the uterus should be included in the differential diagnosis of benign or malignant tumors containing osteoclast-like giant cells.

Abstract
Numerous histologic variants of uterine leiomyomas have been described. The main interest in recognizing these variants is differentiating them from leiomyosarcoma. Osteoclast-like giant cells (OLGC) have been described in association with leiomyosarcoma but to our knowledge, never with leiomyoma. We here report the case of a 58-year-old woman who underwent an elective total hysterectomy with bilateral salpingo-oophorectomy and bilateral pelvic lymphadenectomy for endometrial atypical complex hyperplasia. Multiple typical uterine leiomyoma were identified. One of them showed numerous OLGC admixed with fascicules of bland smooth muscle cells. No atypical features were identified in multiple sections of this otherwise classic uterine leiomyoma. The OLGC showed strong positivity for CD68. The patient, on follow-up, did not show any evidence of recurrent or metastatic disease. This unusual finding expands the morphologic spectrum of uterine leiomyomas. When confronted with a uterine smooth muscle cell tumor with an OLGC component, it is important to search for atypical features diagnostic of leiomyosarcoma.

Undifferentiated (anaplastic) carcinoma with osteoclast-like giant cells of the pancreas: a series of 5 cases with clinicopathologic correlation and cytomorphologic characterization. J Am Soc Cytopathol 2016; 5:321-330. [PMID: 31042543 DOI: 10.1016/j.jasc.2016.04.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Revised: 04/10/2016] [Accepted: 04/11/2016] [Indexed: 01/10/2023]
Abstract
INTRODUCTION Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas (UCOGCP) is a rare neoplasm involving the pancreas. Although typically diagnosed initially via endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), cytomorphologic characterization of the neoplasm has been limited to individual cases in the literature. MATERIALS AND METHODS Five cases were identified in a retrospective review of our institution's records from 2006 to 2015. Cytomorphologic, immunophenotypic, and corresponding clinical features of the neoplasm are examined and described. RESULTS UCOGCP accounted for 0.9% of all new pancreatic neoplastic diagnoses, had a median greatest dimension of 4.3 cm, were variably located within the pancreas, and had variable features by radiologic imaging. Patients were of a median age of 78 years old at diagnosis, and had a median length of survival of 10 months. Smear-based cytomorphology and histomorphology from cell block preparations show atypical/pleomorphic mononuclear carcinomatous and bland osteoclast-like giant cellular populations. The immunophenotype of the mononuclear carcinomatous component was CD68, CD99, CK7 (variably), CKAE1/AE3 (variably), and, rarely, p40-positive. The osteoclast-like giant cells positively expressed CD68 and CD99. CONCLUSIONS Initial diagnosis of UCOGCP is frequently made via EUS-FNA of pancreas tumors, with cytomorphologic features on smears and hematoxylin and eosin stained slides prepared from cell block material being characteristic for the diagnosis. Although the cellular constituents have a consistent immunophenotype, the diagnosis can be based on the morphologic features alone. UCOGCP is an important diagnosis as it may have a distinct clinical course from undifferentiated carcinomas of the pancreas lacking osteoclast-like giant cells.

Abstract
BACKGROUND Adenosquamous carcinoma (ASC) is a rare disease involving various organs, yet there are no large-scale population-based comparative studies on ASC among different organs. METHODS The incidence and overall survival of ASC among various organs in cases diagnosed in Taiwan from January 1, 2003 to December 31, 2010 were calculated and compared using data from the Taiwan Cancer Registry (TCR). The various organs were classified and divided into three different systems: the female reproductive, respiratory, and alimentary systems. Survival analysis were also compared among 30,850 patients diagnosed as ASC, adenocarcinoma (AC) or squamous cell carcinoma (SCC) in organs with frequent ASC. RESULTS During the study period, a total of 576 ASC cases were diagnosed in Taiwan. The most common primary system was respiratory (73.8%), followed by alimentary (16.2%) and female reproductive (10%). The overall survival were significantly higher for cases involving the female reproductive system, followed by the respiratory and alimentary systems (P = 0.016). The median overall survival were worse in males than females for cases involving the respiratory system (22.4 vs. 31.8 months, P = 0.044). Multivariate analysis showed that age ≧ 65, more advanced T and N categories were independent unfavorable prognostic factors of overall survival in ASC. ASC histology is an independent unfavorable prognostic factor compared with AC and SCC. CONCLUSIONS ASC at an old age and more advanced T and N categories were found to be associated with a poor prognosis.

Abstract
Osteoclast-like giant cells (OLGCs) are multinucleated cells of histiocytic lineage and have been identified in a wide array of neoplasms. In the uterus, they have most frequently been reported in association with leiomyosarcomas. This article describes a case of an osteoclast-like giant cell-rich uterine tumor that was essentially indistinguishable at the morphologic and immunophenotypic levels, from typical giant cell tumor of bone. This is the first example of such a case that has been reported in the uterus to the authors' knowledge.

Abstract
Poorly differentiated endometrial carcinomas of specific type include the rarely reported endometrial carcinoma with a malignant giant cell component [endometrial giant cell carcinoma (GCC)]. Since the initial description in 1991, there has only been 1 subsequent case report of this entity. We report another 5 cases. The patients ranged in age from 53 to 83 years, presenting with vaginal bleeding, anemia, or a pelvic mass. Four of the 5 tumors contained areas of endometrial adenocarcinoma of usual type, with a variable giant cell component. The conventional cell types present included 1 case with clear cell carcinoma (30% of tumor volume), 2 with high-grade endometrioid carcinoma (50% and 70% of tumor volume, respectively) and 1 with serous histology (10% of tumor volume). One was composed exclusively of giant cell carcinoma. The giant cell component in all cases consisted of poorly cohesive nests of bizarre multinucleated giant cells with mononuclear tumor cells. A striking peritumoral and intratumoral inflammatory cell infiltrate composed of lymphocytes, plasma cells and focal eosinophils, and neutrophils was present and emperipolesis was noted in 4 of the 5 cases. The giant cells showed focal staining for epithelial markers (AE1/AE3 and CAM 5.2). Three of the patients presented with stage 1A disease, 1 with stage 1B disease, and 1 tumor was advanced, presenting as stage IIIC2. One patient in whom the tumor was exclusively of the giant cell type, developed lung metastasis 4 years after diagnosis and 1 patient is disease free after 14 years. The remaining 3 patients showed no evidence of disease with 15 to 32 months of follow-up. As histotype supplemented by staging information is critical in selection of treatment modalities and in prognostication in uterine malignancies, accurate classification is mandated. Here, we present a series of endometrial carcinomas containing a component of GCC and discuss the spectrum of giant cell-containing uterine neoplasms. At this time, however, the cumulative data on endometrial GCC are limited and the prognostic significance of the presence and the extent of a giant cell component in endometrial carcinoma remains uncertain.

Abstract
Giant cell tumor of the salivary gland is extremely rare, with only 15 cases published in the English literature. The tumor characteristically contains a mixture of multinucleated giant cells, resembling osteoclasts of bone, and neoplastic mononuclear cells. In about half of the reported cases, there is an associated carcinomatous component. We are reporting an additional case of giant cell tumor of the parotid gland that was initially misinterpreted as an extraosseous osteosarcoma in the biopsy specimen. The histologic and immunohistochemical findings as well as a review of the literature with discussion of the histogenesis of this unusual neoplasm are presented.
