    ..Pleomorphic AFH should be included in the differential diagnosis of atypical mesenchymal tumors of skin and superficial subcutis and molecular testing may prove helpful in this regard. ..

    ..In this report, we describe two additional cases of INI1-deficient sinonasal carcinoma prospectively identified, both of which appeared to have a marked response to neo-adjuvant chemoradiation, a finding not previously described. ..

    ..These tumours may manifest largely as sarcomas appearing to be undifferentiated and should be considered in their differential diagnosis...

    ..Three cases showed skin or bone invasion. None had lymph node/distant metastases. In summary, OMEC behaves as a low-grade tumor, and is diffusely positive for p63, which may aid in its differential diagnosis...

    ..They showed negligible MIB-1 staining. This report describes, for the first time, an entirely intranodal location for a low-grade intraductal carcinoma (so-called low-grade cribriform cystadenocarcinoma)...

    ..The spindled component also expressed nuclear AR. AR positivity has not been described previously and may explain the occurrence primarily in men in postpubertal life...

    ..None of these markers definitively correlated with patient outcome. Neurotrophin receptors do not appear to have a prognostic role; however, Trk's may play an oncogenic role in olfactory neuroblastoma. ..

    ..Follow up demonstrated one recurrence (7.1%) higher than reported elsewhere in the body. These latter features may add to the challenge in diagnosing NF in these locations...
