Large cell lung carcinoma (LCLC), rhabdoid phenotype (RP) is a rare entity, accounting for 0.1-1% of all lung tumors. It is characterized by presence of more than 10% cells with rhabdoid morphology-large cells with abundant cytoplasm, eccentric nuclei, prominent nucleoli and eosinophilic cytoplasmic inclusions. We report a case of rhabdoid variant of large cell carcinoma in a 65-year-old female. Patient presented with a lump in the right axilla. Computed tomography showed a large mass lesion in right lung with involvement of the chest wall. Tru-cut biopsy from the lung lesion was performed and histopathology was compatible with LCLC. A RP was considered due to the presence of tumor cells with eosinophilic cytoplasmic globules and eccentric nuclei. Cytokeratin and vimentin were diffusely positive while thyroid transcription factor was focally positive. INI-1, desmin, calretinin, HMB-45, and neuroendocrine markers were negative. This case highlights that recognition of large cell carcinoma lung, RP is very important because of its aggressive nature and adverse outcome
