Modified H & E staining technique for fine needle aspiration cytology (FNAC) smears.
Papanicolaou (Pap) staining procedure has achieved worldwide acceptance in cytology practice due to its crisp cytological details. There are many centres or private laboratories in our country which cannot fulfill the economic requirement of Pap staining and hence employ comparatively cheaper haematoxylin and eosin (H & E) stain. Although routine H & E cannot replace Pap, this study is an attempt to modify H & E staining that would offer comparable diagnostic results. The present study is restricted to FNAC material from palpable lesions i.e.breast and lymph nodes. For this purpose 50 lymph nodes ( LN) and 18 breasts were aspirated. Out of two fixed smears, 1 was stained by Pap technique for routine reporting and other by modified H & E method which was examined and reported by other pathologist, Dr. Sangeeta B. Desai ( SBD) The diagnosis of both the techniques were compared. Emphasis was also given on cytomorphological characteristics. Out of fifty lymph node aspirates from various sites, no diagnostic discrepancy was observed in 46 cases. Three out of 4 had sampling errors whereas, poor nuclear staining was noticed in a single case. Out of eighteen breast aspirates concordant diagnosis was achieved in 16 cases. Out of two discrepant diagnosis 1 was due to sampling error, and the other was an interpretative error. All the cases were confirmed histologically. In conclusion, modified H & E staining is useful for common sites of aspirations of superficial lesions.
