Most Osteomalacia-associated Mesenchymal Tumors Are a Single Histopathologic Entity: An Analysis of 32 Cases and a Comprehensive Review of the Literature
Most cases of mesenchymal tumor-associated OO, both in the present series and in the reported literature, are due to PMTMCT, and improved recognition of their histologic spectrum, including the presence of bone or osteoid-like matrix in otherwise typical cases and the existence of malignant forms, should allow distinction from other meschymal tumors.

Mammary Analogue Secretory Carcinoma of Salivary Glands, Containing the ETV6-NTRK3 Fusion Gene: A Hitherto Undescribed Salivary Gland Tumor Entity
The results strongly support the concept that MASC and AciCC are different entities. Expand
A Clinicopathologic Study of 45 Pediatric Soft Tissue Tumors With an Admixture of Adipose Tissue and Fibroblastic Elements, and a Proposal for Classification as Lipofibromatosis
The clinicopathologic features associated with 45 cases of this soft tissue entity, a rare pediatric neoplasm that has been variously interpreted as a type of infantile or juvenile fibromatosis, a variant of fibrous hamartoma of infancy, and a fibrosing lipoblastoma, are detailed. Expand
Mucinous Carcinoma of the Skin, Primary, and Secondary: A Clinicopathologic Study of 63 Cases With Emphasis on the Morphologic Spectrum of Primary Cutaneous Forms: Homologies With Mucinous Lesions in
It is demonstrated that primary cutaneous mucinous carcinomas span a morphologic spectrum compatible to their mammary counterparts, and most lesions seem to originate from in situ lesions that may represent, using mammary pathology terminology, ductal hyperplasia, atypical ductal Hyperplasia or ductal carcinoma in situ or a combination of the three. Expand
Lesions of Anogenital Mammary-like Glands: An Update
The best approach to the diagnosis of these lesions is to relate them to analogous well recognized lesions occurring in the breast, that is, through the eyes of a breast pathologist, to enable their recognition, precise classification and should introduce greater uniformity in how they are reported in the literature.

  • 14 November 2014
Although this tumor may undergo dedifferentiation and metastasize, sometimes after a prolonged delay, metastatic disease is rare in the absence of high-grade nuclear atypia or coagulative necrosis and showing a strong relationship with SDH germline mutation. Expand
Primary Thyroid-like Follicular Carcinoma of the Kidney: Report of 6 Cases of a Histologically Distinctive Adult Renal Epithelial Neoplasm
Thyroid-like follicular renalcell carcinoma represents a unique histologic subtype of renal cell carcinoma of low malignant potential and its primary importance is to distinguish it from metastatic carcinoma from the thyroid. Expand
High-grade urothelial carcinoma of the renal pelvis: clinicopathologic study of 108 cases with emphasis on unusual morphologic variants
The study highlights the fact that, in the renal pelvis, urothelial carcinomas show a tendency to frequently display unusual morphologic features and metaplastic phenomena, and attention to proper sampling as well as the use of immunohistochemical stains will be of importance to arrive at the correct diagnosis.

Mammary Analogue Secretory Carcinoma of Salivary Glands With High-grade Transformation: Report of 3 Cases With the ETV6-NTRK3 Gene Fusion and Analysis of TP53, &bgr;-Catenin, EGFR, and CCND1 Genes
Recognizing HG-transformed MASC and testing for ETV 6 rearrangement may be of potential value in patient treatment, because the presence of the ETV6-NTRK3 translocation may represent a therapeutic target in MASC. Expand
Pigmented (melanotic) neurofibroma: a clinicopathologic and immunohistochemical analysis of 19 lesions from 17 patients.
The clinicopathologic features associated with 19 specimens removed from 17 patients, including eight patients known to have neurofibromatosis and two others strongly suspected of having this disorder, are analyzed. Expand
