Background:
The diagnosis of skin adnexal tumors is usually based on histopathology. However, fine-needle aspiration cytology (FNAC) can be of great help and shows a high degree of correlation to the final diagnosis. It is helpful in many situations where skin lesions are a manifestation of certain systemic syndromes and aids to the formation of precise treatment plans.
Materials And Methods:
This prospective study was carried out to assess the diagnosis of skin adnexal tumors based on FNAC and their comparison with histopathological diagnoses. There were 14 patients with FNAC and histopathological follow-up in whom a final diagnosis of skin adnexal tumor was made. The results of FNAC were compared with histopathological diagnoses for complete correlation, partial correlation (cases where an FNAC diagnosis of skin adnexal tumor was made but a precise diagnosis of the subtype was not possible) or no correlation (where FNAC failed to diagnose a skin adnexal tumor).
Results:
Among the 14 cases of skin adnexal tumor, there was total correlation between the FNAC diagnosis and final histopathological diagnosis in 8 cases (57.1%) and a partial correlation in 4 cases (28.5%). There was no correlation of the FNAC diagnosis with the histopathological diagnosis in only 2 cases (14.3%).
Conclusions:
FNAC is very useful in making a diagnosis of skin adnexal tumors and helps in the management of the patient.
