A Case Report of Anti-TIF1-γAntibody-Positive Dermatomyositis Concomitant with Small Cell Neuroendocrine Carcinoma of the Urinary Bladder

Figure 2

Images of small cell neuroendocrine carcinoma (SCNEC) of the urinary bladder. (a) SCNEC showing high-grade nuclei without nucleoli and with scant cytoplasm by haematoxylin-eosin staining. (b) Tumour cells are partially positive for chromogranin A. (c) Tumour cells are weakly positive for synaptophysin. (d) Tumour cells are diffusely positive for CD56. (e) Tumour cells are strongly positive for TIF1-γ while surrounding normal cells are negative. (f) Corresponding table of tissue staining.
