Description
Inverted follicular keratosis (IFK) is a solitary benign epithelial tumor of infundibular hair follicle, generally observed in middle-aged and older individuals. An elderly male presented with a rough & raised pink colored lesion on the bald area of parietal scalp since 4 months. Fine needle aspiration (FNA) followed by histopathologic examination of the lesion was done. The FNA smears revealed features suggestive of intra-epidermal inclusion cyst while the final diagnosis of IFK was established on histopathological examination. The present article describes a correlation between the cytopathological features and histomorphology of IFK. The cytopathological features of IFK have not been described in the literature yet, hence this article provides a chance to study cytopathological features of this rare lesion.
