Objective: To investigate the pathological features and the clinicopathological significance of TERT detection in those tumors that were difficult to diagnosis. Methods: A total of 93 cases of fibroepithelial tumors without definite diagnosis were collected from the Affiliated Hospital of Qigndao University between 2013 and 2021. The clinical details such as patients' age and tumor size were collected. All slides were re-reviewed and the pathologic parameters, including stromal cellularity, stromal cell atypia, stromal cell mitoses, and stromal overgrowth were re-interpreted. Sanger sequencing was used to detect TERT promoter status, and immunohistochemistry was performed to detect TERT protein expression. The relationship between TERT promoter mutation as well as protein expression levels and the clinicopathological parameters were also analyzed. Results: The patients' ages ranged from 30 to 71 years (mean of 46 years); the tumor size ranged from 1.2 to 8.0 cm (mean 3.8 cm). These tumors showed the following morphologic features: leafy structures in the background of fibroadenoma, or moderately to severely abundant stromal cells. The interpretations of tumor border status were ambiguous in some cases. The incidence of TERT promoter mutation was high in patients of age≥50 years, tumor size≥4 cm, and stromal overgrowth at ×4 or ×10 objective, and these clinicopathologic features were in favor of diagnosis of phyllodes tumors. TERT protein expression levels was not associated with the above clinicopathologic parameters and its promoter mutation status. Conclusions: The diagnostic difficulty for the breast fibroepithelial tumors is due to the difficulty in recognition of the leafy structures or in those cases with abundant stromal cells. A comprehensive evaluation combined with morphologic characteristics and molecular parameters such as TERT promoter may be helpful for the correct diagnosis and better evaluating recurrence risk.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by failure of embryologic growth of the mullerian ducts resulting to agenesis or hypoplasia of the uterus and upper part of the vagina while both ovaries and fallopian tubes are normal. Various associated malformation with MRKH syndrome are noted in literature, with a renal system anomaly as the most common. However, adnexal tumors in MRKH syndome are rare. To date there have been no reported cases of fallopian tube tumors in patients diagnosed with MRKH. This paper presents a case of an 18 year old nulligravida who presented with primary amenorrhea secondary to MRKH sydnrome, with an associated Papiliary Serous Cystadenofibroma of the right fallopian tube Management of the case as well as review of related literature are presented. 

Phyllodes tumor is an uncommon fibroepithelial neoplasm of the breast. And it is characterized by expanded stroma with increased cellularity and elongated epithelium-lined clefts. Mammary carcinomas within phyllodes tumors have been rarely reported. To date, however, no reports have described the invasive cribriform carcinoma arising in malignant phyllodes tumor. Here, we report a 62-year-old woman who presented with a large breast mass. Microscopically, the mass was a typical malignant phyllodes tumor showing well developed leaf-like architecture and stromal overgrowth with high cellularity and nuclear pleomorphism. In a portion of the tumor, however, the epithelial component showed a cribriform pattern of proliferation in the absence of myoepithelial cells, suggestive of the invasive cribriform carcinoma. To our knowledge, this is rare and it is difficult to make a differential diagnosis of it. Here, we report our case with a review of literatures.

Fibroepithelial polyp (FEP) and lymphangioma circumscriptum (LC) of the vulva are rare diseases that occur generally in young to middle-aged women. The pathogenesis of FEP is not clearly understood. Several previous cases have suggested that a hormonal influence may be a predisposing condition for developing FEP with or without chronic inflammation. A 68-year-old postmenopausal woman presented with a history of multiple raised lesions on the vulva with a 1-year duration. Additionally, a pedunculated mass had appeared 6 months earlier in the left lower labia minora. The patient underwent simple excision by electrocautery. The final pathological diagnosis was FEP with LC. In this case, the development of FEP was associated only with chronic inflammation induced by LC. Therefore, the case supports the hypothesis that a chronic inflammatory process may be related to the development of FEP even without hormonal influence.

Ovarian clear cell adenocarcinomas (CCACs) are frequently associated with endometriosis and, less often with clear cell adenofibromas (CCAFs). We encountered a case of ovarian CCAC arising from benign and borderline adenofibromas of the clear cell and endometrioid types with endometriosis in a 53-year-old woman. Regions of the adenofibromas showed transformation to CCAC and regions of the endometriosis showed atypical endometriotic cysts. This case demonstrates that CCAC can arise from CCAF or endometriosis.

We report a case of primary fibroepithelial polyps (FEPs) in the middle of both ureters in a patient with advanced gastric cancer and acute renal failure. Ureteral FEPs are rare benign lesions, and multiple, bilateral lesions are extremely rare. To our knowledge, this report is the seventh case of bilateral FEPs in the literature. Our case has clinical implications because FEPs should be considered as a cause of ureteral obstruction inducing acute renal failure in advanced gastric cancer.

A fibroepithelial polyp of the bronchus is a rare, benign, and endobronchial tumor, histologically consisting of fibrovascular stroma covered by normal respiratory epithelium. We report a case of a fibroepithelial polyp arising from the left main bronchus. On CT, a characteristic lobulating contour of the endobronchial nodule was well visualized, which histopathologically represented a typical papillary growth pattern of the nodule. Such a lobulating contour of the nodule might help make a correct diagnosis of this rare disease among other various endobronchial neoplasms.

Fibroepithelial polyps are a benign neoplasm of mesodermal origin that usually occur in the urinary tract. However, a giant fibroepithelial polyp of the glans penis is very rare and is strongly linked with long-term condom catheter use. In this article, we report a case of a 45-year-old man who presented with a giant fibroepithelial polyp originating from the glans penis. Physical examination showed a 6x3 cm sized mass lesion overlying the ventral surface of the glans near the urethral meatus without urethral communication. For the previous 10 years, the patient had been required to use a condom catheter secondary to paraplegia sustained during a T12-L1 spinal cord injury. He was successfully treated by wide local excision of the mass and suprapubic cystostomy placement. There was no evidence of recurrence after 12 months of follow-up.
