ABSTRACT
Background: Rapidity and reliability are the major advantages of cytopathology in tumor diagnosis. The need for minimal turnaround time for assessing cytological smears has encouraged innovations in staining techniques that require lesser staining time with unequivocal cell morphology. Rapid Pap staining was introduced as a hybrid to conventional Pap stain. It improves staining quality, gets over the staining time in restriction, and is a more efficient technique financially. In the present study, a modified staining technique was adopted where phloxine is added as one of the cytoplasmic stain components in rapid Pap stain kits. Objective: The aim of this study was to assess whether the modification of the existing procedure by adding phloxine as one of the components of the cytoplasmic stain intensifies the cytoplasmic differentiation and cytoplasmic staining in gynecological smears. Materials and Methods: This was a prospective study done on 50 cases of gynecological smears. Two smears were collected from each patient and fixed in 100% propanol and stained with the rapid Pap stain kit procedure and modified rapid Pap stain with phloxine. Slides were then analyzed by two pathologists blinded to the staining method used. Five parameters were considered and scored (background, cell morphology, nuclear staining, cytoplasmic differentiation, and cytoplasmic staining). The quality index for each method was calculated by finding out the ratio of the actual score obtained to the maximum score possible. Results: Both the staining methods had comparable results. For both pathologists, the quality index calculated for modified Pap stain was found to be marginally higher than the quality index for rapid Pap. The mean quality index was comparable for modified Pap (0.91) and rapid Pap (0.89). Conclusions: The efficacy of modified Pap stain with phloxine to distinctly stain the cytoplasm is comparable with that of rapid Pap stain. In addition, the intensity of staining can be enhanced with little cost outlay, and this can be especially beneficial in low-resource settings.
ABSTRACT
Ectopic prostate tissue is a rare phenomenon. Histologically and immunohistochemically it is indistinguishable from normal prostatic tissue but it is difficult to recognize and may be confused with malignancy when presenting as ectopic lesion in the urinary system. Therefore, awareness of this entity is essential for both urologists and pathologists to prevent misdiagnosis.
