ABSTRACT
A 53-year-old male presented with a right inguinal mass of one-year duration. The fine needle aspiration of the inguinal mass showed a highly cellular tumor composed of sheets and isolated, large round to polygonal cells with moderate pleomorphism. Many bare nuclei were seen with occasional intranuclear inclusions. A provisional diagnosis of metastasis probably of testicular tumour was made. The orchidectomy showed a brown tumor replacing the entire testis and infiltrating the epididymis. The histological features showed Leydig cell tumor without Reinke crystalloids.

Metaplastic changes are commonly found at widespread locations occurring in both reactive and neoplastic conditions. They can simulate tumors histologically. Squamous metaplasia is rarely seen in areas of fibrosis and inflammation secondary to hemorrhage in nodular goiters. If it is extensive with associated degenerative changes and present clinically in the form of a nodule, cytopathologist must take care to differentiate this from primary or metastatic squamous cell carcinoma or even anaplastic carcinoma.
