A Rare Tumor in a Patient with Hepatic Hydatic Cyst: Adrenal Hepatoid Adenocarcinoma
Figure 2
The hystopatological findings of the patient’s tumor. (a) The overall view suggested hepatocellular carcinoma (HE ×200) (the big figure). On the below, from left to right we can see the adenoid areas, adrenal invasion, and diaphragmatic invasion (HE ×100, HE ×100, and HE ×40). (b) Thick trabecular structures areas suggesting hepatocellular carcinoma (HE ×200). Reticulin texture, trabecular structures on the left below, and sinusoidal structures with CD34 on the right below (small figures). (c) Her Par1 positivity of tumor cells on the left below (her Par1 ×200); generalized AFP expression of the tumor cells in the middle below (AFP ×100); canalicular type positivity with pCEA on the right below (pCEA ×200). (d) Generalized cytokeratin positivity in the adenoid areas (CK7 ×200) (the big figure); cytokeratin 19 positivity peripherally to the nodule (CK19 ×100) (the small figure on the right above).
