Buccal Mucosa Exfoliative Cell Prussian Blue Stain Co-Relates with Iron Overload in ß-Thalassemia Major Patients.

Thalassemics require regular blood transfusion therapy leading to iron overload in the body tissues, which is a major cause of morbidity and mortality in these patients. We hereby attempted to measure this iron overload by means of exfoliative cytology, a non-invasive and inexpensive technique. The aims and objectives of our study were: 1. To detect iron overload by oral exfoliative cytology using Perl's Prussian blue stain in ß-thalassemia major patients. 2. To correlate staining positivity with serum ferritin levels. Smears were obtained from buccal mucosa of 50 ß-thalassemia major patients (who had taken more than 12 transfusions) and 25 healthy subjects of the same age group as controls. Smears were stained with Perl's Prussian blue. Blood samples were taken from the study group for estimation of serum ferritin levels. Grading criteria were defined for assessing the Prussian blue positivity. Perl's positivity was observed in 49 out of 50 of thalassemic patients (98%). 1 patient had Grade 0, 7 patients had Grade I, 5 had Grade II, 12 had Grade III, 14 had Grade IV while 11 patients had Grade V positivity. Spearman Rank's Correlation Co-efficient was 0.38, signifying a weak positive correlation between positivity of buccal smears for Perl's Prussian blue staining and respective serum ferritin levels. Perl's Prussian blue staining of exfoliated cells from buccal mucosa can be used to assess iron overload in ß-thalassemia major patients, as a screening as well as diagnostic tool. With the grading system we can give a semi-quantitative assessment of the same.

Fibroadenoma in Axillary Ectopic Breast Tissue Mimicking Lymphadenopathy.

Swellings in the axilla especially in women are always viewed with suspicion owing to a large number of these being associated with breast carcinoma presenting as nodal metastasis. In a country like India, tuberculous lymphadenopathy is also amongst the first differentials. We present a case of a woman with right sided axillary swelling mimicking lymphadenopathy which on Fine Needle Aspiration Cytology (FNAC) turned out to be fibroadenoma of the ectopic breast tissue. This condition is a rare occurrence in Ectopic Breast Tissue (EBT) as opposed to that in the normal breast, the most common pathology affecting ectopic breast being carcinomas.
