Most clear cell neoplasms of the ovaries are carcinomas; benign and borderline clear cell tumors are uncommon. To date, only 12 cases of benign clear cell adenofibroma have been reported in the literature. Here we report a case of benign clear cell adenofibroma of the left ovary in a 51-year-old postmenopausal woman. Histological examination revealed widely spaced simple glands embedded in a dense fibrous stroma. The glands were lined by one to two layers of cells with abundant clear cytoplasm. The nuclei were bland and uniform in size and shape. There was minimal cytologic atypia in some areas. In this article we discussed the criteria for the diagnosis of benign and borderline clear cell adenofibromas and reviewed the literature.
Nodular breast lesions of noncarcinomatous origin are often of fibroepithelial origin. They may cause classification problems when they are hypocellular or hypercellular; the latter setting may also raise the differential diagnosis of phyllodes tumors. Thirty equivocal nodular breast lesions were collected and one hematoxylin and eosin slide from each was assessed by six pathologists with special interest in breast pathology. The overall reproducibility of classifying these lesions into categories of fibroadenoma, phyllodes tumor or anything else was moderate (kappa value: 0.48). The lack of a uniform nomenclature was not felt disturbing for hypocellular lesions, but the discordant diagnosis of tumors resembling or representing phyllodes tumors was acknowledged to require intervention, such as more obvious implication of guidelines and quality assurance programs aiming at assessing diagnoses and prognostic parameters.
Tamoxifen therapy may result in a variety of endometrial proliferative lesions, including adenofibroma and endometrial stromal sarcoma (ESS). This report describes the MR findings of adenofibroma and ESS associated with tamoxifen therapy. When MRI demonstrates a uterine mass appearing as a heterogeneous mass in the endometrium or myometrium, adenofibroma and ECC must be considered as rare, but possible, diagnoses.
