@entity259 is the commonest endocrine @entity5 and is the second most common @entity5 affecting young females in Oman. The diagnosis of @entity3557 ( @entity3557 ) is based primarily on histologic architecture and nuclear morphology in routine Haematoxilin and Eosin (H _ E) stained slides. Whenever in doubt, immunohistochemistry may be helpful. This retrospective study included 115 cases of @entity3557 diagnosed at a tertiary care center in Oman over 10 years period, from 2001 to 2010. Slides and blocks of these cases were retrieved from the pathology laboratory. Ninety five (95) were females and 20 were males. @entity3557 ( @entity3557 ) was most commonly seen in the 20 - 50 years of age. The commonest morphologic variant seen in this population was classical papillary variant in 44/115 (38%) followed by @entity1377 (n=30/115, 26%) and follicular variant of @entity1377 (n=18/115, 15.6%). Out of the 30 micro- @entity189 cases, 18 were diagnosed incidentally in thyroids operated for @entity8170 . Immunohistochemical marker @entity4166 was positive in 29/31, HBME-1 and HMW-CK in 15/15 cases; CEAwas in one case where it was reported negative. Immunohistochemical stains were useful in cases with atypical /doubtful morphology.
