1 TABLE SSTR2A expression scores in trichogerminomas, follicular and no follicular differentiation tumours. Trichogerminoma (TG) is a rare follicular neoplasm characterized by immature morphology and "cell ball" formation.[1] This entity should be distinguished from other follicular neoplasms composed of germinative cells notably trichoblastoma and basal cell carcinoma. To conclude, we reported intense and expression of SSTR2A in more 50% of tumour cells in TG, which might therefore be used as an additional immunohistochemical marker for the diagnosis of this neoplasm.
