Best practices in diagnostic immunohistochemistry: pleomorphic cutaneous spindle cell tumors.
CONTEXT Pleomorphic cutaneous spindle cell tumors can be difficult to distinguish solely on histologic grounds. The use of ancillary immunohistochemical studies can greatly assist in this differential diagnosis. OBJECTIVE To review histologic and immunohistochemical aspects of cutaneous spindle cell tumors and discuss a basic panel of markers to assist in the differential diagnosis. DATA SO...
متن کاملGastrointestinal tract spindle cell tumors with interstitial cells of Cajal: Prevalence excluding gastrointestinal stromal tumors
Leiomyomas and schwannomas of the gastrointestinal tract (GIT) are mainly comprised of spindle-shaped tumor cells and should always be differentiated from gastrointestinal stromal tumors (GISTs). Mast/stem cell growth factor receptor Kit (KIT) and discovered on GIST-1 (DOG1) are well-known diagnostic markers for the detection of a GIST by immunohistochemical staining. The aim of the present stu...
متن کاملSpindle cell melanocytic tumors
pseudoinclusions are sometimes evident and mild nuclear pleomorphism is typical. Mitoses are either absent or extremely infrequent. By definition dendritic cells are said not to be seen in this lesion. The growth pattern often presents a plexiform appearance, fascicles of nevus cells following the dermal appendages and neurovascular bundles. Perineural or endoneural extension is a very common f...
متن کاملautoradiography in spontaneous canine tumors: comparison with pimonidazole hypoxia immunohistochemistry
Background: The aim of this study was to compare Cu-diacetyl-bis(N-methylsemicarbazone) (Cu-ATSM) and FDG PET uptake characteristics and Cu-ATSM autoradiography to pimonidazole immunohistochemistry in spontaneous canine sarcomas and carcinomas. Methods: Biopsies were collected from individual tumors between approximately 3 and 25 hours after the intravenous injection of Cu-ATSM and pimonidazole...
متن کاملDoes immunohistochemistry provide additional prognostic data in gastrointestinal stromal tumors?
BACKGROUND To investigate the predictive and prognostic effects of clinicopathologic and immunohistochemical (IHC) features in patients with gastrointestinal stromal tumours (GISTs). MATERIALS AND METHODS Fifty-six patients who were diagnosed with GIST between 2002 and 2012 were retrospectively evaluated. Relationships between clinicopathologic/immunohistochemical factors and prognosis were i...
