ABSTRACT Bckground: Brest lesions re one of the most commonly encountered lesions in women which require prompt pthologicl confirmtion y fine needle spirtion cytology (FNAC) nd histopthologicl exmintion. Methods: We conducted prospective study from Jnury 2015 to Decemer 2015. A totl 98 cses included presenting with plple rest lump in which 80 cses were lso sujected to surgicl iopsy or mstectomy. Results: Out of 98 cses, 34.7% enign cses, 59.2% mlignnt cses, nd 6.1% non-neoplstic cse were dignosed cytologiclly in which 7 (7.1%) cses of mstitis, 2 cses (2%) of grnulomtous mstitis, 22 cses (22.4%) of firodenom, 11 cses (11.2%) of enign rest disese or firocystic disese, 10 (10.2%) cses of dyskryotic chnges, 45 cses (45.9%) crcinom. Men ge ws 46.4±14.2 yers. Mjority of cses 29(29.6%) elonged to 41-50 yers ge group. Mjority of the msses were situted in the left rest (57.2%) in the upper outer qudrnt (40.8%). In ddition to rest lump, pin in 22 cses, loody dischrge in 5 cses, ulcertion in 8 cses nd nipple retrction in 11 cses were present. Histology ws ville for 80 cses in which 5 (6.3%) cses of non-neoplstic, 27 cses (33.7%) enign nd 48 cses (60%) of mlignnt histology. FNAC proved to e 91.25 % sensitivity in the dignosis of ll rest lesions in our study. Conclusions: So we concluded tht rest lesions re esily ccessile to FNAC, which is n esy, cost effective nd less time-consuming procedure. FNAC is used to dignose oth enign nd mlignnt lesions. Keywords: Brest, Cyto-histologicl correltion, Ductl crcinom, FNAC Brest INTRODUCTION Brest lesions re one of the most commonly encountered lesions in women. All physicins ccept the necessity of otining prompt pthologicl confirmtion of the nture of ny mss in the rest suspected s enign or mlignnt. Since the most importnt prognostic fctor t the time of presenttion is the extent of the disese, it is impertive tht relile preopertive dignosis is estlished s erly s possile with view to institute proper tretment nd reduce the mortlity rtes. In recent yers, mmmry cytology hs een considered s n effective mens of erly dignosis of rest msses. 1 It is minimlly invsive yet mximlly dignostic method, often oviting n open iopsy. It is simple, fst, nd cn e performed s n OPD procedure, since it requires no specil equipment, cuses miniml moridity, nd hs high ptient cceptnce. It is commonly used s prt of the dignostic trid, which in ddition to the FNA include clinicl rest exmintion nd mmmogrphy. The min purpose of Fine Needle Biopsy of rest lumps is to confirm cncer preopertively nd to void unnecessry surgery in specific enign conditions. 2 The dvntge of these cytologicl procedures lies in the fct tht they re simple to perform, cost-effective, rpidly ccepted y the ptient, nd cosmeticlly lest disfiguring. This more rpid dignostic pproch helps to lly the nxiety cused y delys in scheduling, performing, nd interpreting n open iopsy. So, the purpose of this study is to evlute nd to check the ccurcy of Fine-needle spirtion cytology in the dignosis of plple rest lumps.

METHODS The study ws crried out in the deprtment of Pthology, Srdr Ptel medicl college nd ssocited group of hospitls, Bikner. This study included 98 cses presenting with plple rest lump from Jnury 2015 to Decemer 2015. Comprison etween cytology nd histology ws done ccording to vilility of smples. FNA ws performed on ll the plple lumps without locl nesthesi. FNA ws crried out using 10 ml plstic disposle syringe nd disposle needles of 22-23 guge on ll of them, stined with H & E nd Giems stin nd the mteril studied in the Deprtment of pthology. Figure1: Distriution of 98 cses ccording to cytologicl dignosis. 80 cses were lso sujected to surgicl iopsy or mstectomy. All iopsy specimens were processed y fixtion, dehydrtion, nd clering followed y impregntion with wx. The wx locks were cut in 5-6 μ sections & stined y hemtoxylin nd eosin stin. The dignoses in ll the cses were mde on histopthologicl exmintion of routinely processed tissue. All cses were reviewed y the uthors nd dignosis ws confirmed. The reltive frequency of tumors nd the distriution of ge, sex nd loction were nlyzed. Figure 2: Distriution Of 80 ccording to Histologicl Dignosis.

80 cses out of 98 FNAC hd corresponding histologicl dignosis. Out of 80 iopsies done, the discrepncies t cytology were s follows: Three cses of enign prolifertive rest disese in histology were reported s mstitis t cytology (flse negtive dignosis in disese) One cse of Tuerculr mstitis ws wrongly reported s Grnulomtous mstitis t cytology (flse negtive dignosis in disese) (Figure 11) Three cses reported s intrductl crcinom in histology were reported s enign prolifertive rest disese in cytology (flse negtive dignosis in disese). One cse reported s intrductl crcinom disese in histology ws reported s Hypocellulr in cytology (flse negtive dignosis in disese) (Tle 1).

Pttri SK et l. studied 71 histologiclly confirmed cses nd documented infiltrting ductl crcinom s the most common lesion (24/71). 3 Unlike our study, Jyrm G et l. in their study of 543 cses of FNAC found firocystic disese (39.8%) s the most common lesion. 4 Khnn R et l showed 61.3% enign nd non-neoplstic nture of lesions nd 38.7% mlignncy. 5 Mlignnt lesions were much higher in our study s cses were tken minly from cncer l. Oservtions mde in our study differ from other studies proly ecuse of difference in smple collection from cncer l, smple size nd durtion of study. Most common nture of lesions were mlignnt 58 (59.2% confirmed cses) which includes Intrductl crcinom (96.6%), Mucinous crcinom 1 (1.7%), Squmous cell crcinom 1 (1.7%). Benign lesions were 34 (34.7%) which include minly firodenom (64.7%) nd firocystic disese 12 (35.3%). Non-neoplstic lesions were 6 (6.1%) including mstitis 4 cses nd grnulomtous mstitis 2 cses. The ge of the sujects in the present study rnged from 18 yers to 85 yers. Mjority elonged to 41-50 yers ge group (29.6%) with the men ge of 46.4 yers. Averge ge ws slightly lower thn the study undertken y Bhrgv V et l. who found the men ge t 52.26 yers. 6 In the study undertken y Doussl VL et l. the medin ge ws higher nd found to e t 57 yers. 7 Gnit O et l. reported mximum numer of ptients with mlignnt lesions in the fourth to seventh decde of life. 8 In the present study, ll the 98 sujects (100%) presented with rest lump. Out of these, 63 cses (64%) presented with lump s the min presenting symptom while 22 (22.44%) with lump nd pin, 11 (11.22%) with lump ssocited with retrcted nipple nd 8 (8.10%) with lump ssocited with ulcer. In 3(3%) with lump were ssocited with nipple dischrge. In concurrence with this study, rest lump ws the min presenting symptom in the study y Rin V et l. 9 In our study, mjority of the msses were situted in the left rest (57.2%) in the upper outer qudrnt (40.8%). Mjority of non-neoplstic cses were situted in the right rest (66.8%) in the Upper inner Qudrnt (50.2%), enign cses were situted in the left rest (64.7%) in the upper outer qudrnt (50%) nd mlignnt cses were situted in the left rest (55.2%) in the upper outer qudrnt (38%). Out of 122 cses, 60 cses (49.18%) were in left rest, 54 cses (44.26%) were in right rest, nd 8 cses (6.55%) presented ilterlly. 10 Hussin MT et l. reported left rest involvement in 27 ptients (54%) nd right rest involvement in 23 cses (46%) nd concluded similrly tht left rest ws involved more commonly thn right. 11 In the present study, mjority of the tumors (40) were in the upper outer qudrnt (40.8%) followed y upper inner qudrnt 18(18.6%). Meen SP et l. lso found mjority of the tumors in the upper outer qudrnt (54%). 12 In our study, the totl numer of cses dignosed cytologiclly s firodenom ws 22. All were femle ptients ged 18-65 yers. The min fetures of stghorn clusters nd single re ipolr nuclei were seen in ll the cses. Frgments of firomyxoid strom were seen in 21 cses (95.5%) nd Monolyered sheets were seen in 19 cses (86.4%). Cellulr dissocition, nucler pleomorphism, multinucleted gint cells were not seen. Interntionl Journl of Reserch in Medicl Sciences June 2016 Vol 4 Issue 6 Pge 1947
All iopsied firodenoms (18 cses) correlted with the FNA dignosis, giving sensitivity of 100%. The sensitivity of FNAC in dignosing firodenom in our study ws comprle to study y Kollur et l, which gives sensitivity of 100%. 13 In our study, eleven cses were dignosed t cytology s enign prolifertive rest disese. The ge of the ptients ws from 24 to 70 yers. These presented with ill-defined to well-formed msses nd the smers were poorly to modertely cellulr showing few enign clusters of epithelil cells nd myoepithelil cells rrnged minly in sheets. Nucler pleomorphism ws seen in 3 cses in the form of nucleomegly nd prominent nucleoli in some clusters. Bre nuclei were seen ll 11 cses. Few cyst mcrophges were seen in some cses. In 2 cses were lso showed metplstic pocrine cells nd cyst mcrophges with ductl epithelil. Tle 4: Dignostic ccurcy of FNAC in the dignosis of plple rest Lesions.

Infiltrting ductl crcinom ws documented in 199 (71%) cses. The men ge for presenttion of rest crcinom ws 44.1 yers. 14 Our study documented 59.2% incidence of Brest crcinoms, mong which Infiltrting ductl crcinom ws 96.6 % in the ge group 27-80 yers. Mucinous crcinom of rest is reltively rre, pure form ccounting for 2% of ll rest cncers. The common ge is post-menopusl ge. Shrm et l reported 30 yer old femle, dignosed y fine needle spirtion cytology s mucinous crcinom of the rest with lymph node metstsis nd susequently confirmed y histopthology. 15 In our study, we hd one cse of mucinous crcinom dignosed histologiclly in 61 yer old womn. One cse of squmous cell crcinom dignosed histologiclly in 55 yer old womn cytologicl findings did not mtch with squmous cell crcinom. Only mild pleomorphism nd hyperchromtism were seen in oth cses. In the literture, the sensitivity rnges from 80-98% nd the specificity my e up to 100%. Results of our study were comprle to ove studies. High degree of sensitivity nd sensitivity in this study my permit surgicl mngement on pre-opertive cytologicl dignosis (Tle 4). CONCLUSION Considering histologicl dignosis s the gold stndrd, we concluded tht rest lesions re esily ccessile to FNAC, which is n esy, cost effective nd less timeconsuming procedure. FNAC is used to dignose oth enign nd mlignnt lesions. It is more sensitive nd specific in dignosing mlignnt lesions, showing 93.8 % sensitivity nd 100% specificity.
