<p>The aim is to examine the histopathological characteristics and distribution of spindle cell lesions in the head and neck area, utilizing immunohistochemistry for diagnosing challenging cases. Prospective observational study conducted over a period of 2 years (November 2015 to November 2017). Department of Histopathology, Apollo Hospitals, Chennai, India. All spindle cell lesion biopsies of the head and neck were collected, with a total of cases was sixty six (66). Histopathological samples were processed, studied its morphological features under light microscope and the sarcomas were graded using FNLCC system. Appropriate immunohistochemical markers were used according to the histopathological appearance. We found that 51–60 years of age was the most common age group of presentation with a predominance of male patients. The neck was the most common site of occurrence. Benign tumors (69.7%) were more common than malignant tumors (27.7%), with neural tumors (21%) being the most common, followed by fibroblastic lesions (15%). Among malignant tumors, spindle cell carcinoma was the most prevalent (9.1%). Out of 66 cases, 14 cases were subjected to further evaluation through immunohistochemistry for diagnostic purposes. Immunohistochemical analysis was more frequently performed for nodular fasciitis, solitary fibrous tumor, dermatofibrosarcoma protuberans, spindle cell carcinoma, and glomangiopericytoma compared to other lesions. Histomorphology remains the gold standard for diagnosing various entities of spindle cell lesions of the head and neck. Immunohistochemistry played a vital role in diagnosis of some of difficult cases where histomorphology was inconclusive.</p>
