RESUMO
Adenoid cystic carcinoma occurring in the external auditory canal is very rare. Two cases are being reported. One was diagnosed on cytology based on which surgery was planned. In the second case, fine needle aspiration procedure had to be abandoned due to severe pain and a biopsy was required for its diagnosis. Morphologically, it resembles its more common salivary gland counterpart. Though severe pain during needling may be a limiting factor, adenoid cystic carcinoma of external auditory canal can be confidently diagnosed on cytology based on which surgical management can be planned.
RESUMO
Sickle cell anaemia is a common and widespread haemoglobinopathy with large clinical heterogeneity. The present study, was undertaken to determine seven different haematological parameters (Haemoglobin percent, RBC count, PCV, MCV MCH, MCHC, Reticulocyte count) on total 102 heterozygous (SA) and homozygous (SS) sickle cell children under six years of age. In addition, fetal haemoglobin (HbF) level was estimated in SS children and correlated with clinical status, gender and ethnic background. Mean HbF was 16.79%. Higher HbF level was associated with less severe clinical feature. HbF was not influenced by gender and ethnic background. In homozygous children mean values of MCV, MCH, MCHC were decreased while reticulocyte count was increased as compared to control (AA) children and (SA) children (P < 0.05) We conclude that, in sickle cell disease, HbF was a good prognostic indicator. Higher HbF level along with microcytic hyopochromic indices and lower MCHC was found to be a feature of the study population.
