Objective: Nested type transitional cell carcinoma of the bladder is a rare histological variant among bladder tumors. Although clinical presentation is similar to the other bladder tumors, its macroscopic appearance may be equivocally benign, with submucosal growing which is difficult to detect on cystoscopy, so that diagnosis may be delayed.
Methods: We present the characteristics of nested type transitional cell carcinoma and review the differential diagnosis for this entity with possible counterfeiters.
Objective: Two cases of metanephric adenoma are presented, a rare benign renal tumor, and a literature review is done under the current WHO classification (2016).
Methods: Standard histopathological study was performed with hematoxylin-eosin and immunohistochemistry to analyze the expression of WT, Vimentin, Racemase, CK7, CD10 and RCC.
Results: Neoplasms of 3 and 4.
DOG1 is a highly-sensitive marker often included in the immunohistochemical panel for the diagnosis of gastrointestinal stromal tumors (GISTs). Recent research has shown that DOG1 may also be expressed by low-grade fibromyxoid sarcomas (LGFMSs); this may give rise to diagnostic error when the sarcoma is located in the abdominal cavity. This paper reports on immnohistochemical expression of DOG1 in 19 LGFMSs using two different monoclonal antibodies: K9 (Leica, Novocastra Laboratories, Newcastle upon Tyne, UK) and SP31 (Thermo Scientific, Freemont, USA).
