Aspiration cytology, histology and hormone status in solid and cystic papillary tumor of pancreas--report of three cases.
Solid and cystic papillary tumor of pancreas (SCPT) are rare tumors. Of the well described cases 95% have occurred in women of reproductive age, suggesting a role of hormonal factors in the pathogenesis of this tumor. Only few studies evaluating estrogen and progesterone receptor status have found it to be positive. Cytohistocorrelation and immunohistochemistry for estrogen (ER) and progesterone (PR) receptors of three such cases are reported here. All three were diagnosed by fine needle aspiration cytology (FNAC) and showed cytoplasmic positivity for ER and PR receptors. May-Grunwald Giemsa, Papanicolaou and hematoxylin and eosin stained slides were evaluated for cytology and histopathology. Unstained methanol fixed slides were used for immunohistochemistry. The cytoplasmic staining of ER and PR receptors cannot be underestimated, as shown by Carbone A et al which represents ERII receptors. This study confirms the presence of ER and PR receptors in these tumors and highlights the already established cytological features.
