ADRENAL CORTICAL CARCINOMA
-
Malignant tumor arising from adrenal cortical cells
-
Age – more common in 4th and 5th decades but can occur at any age
-
Sex – Slight female predilection
-
Left gland is involved more than right
-
These tumors can be functional or non functional
-
Signs and symptoms –
-
Abdominal or flank pain, discomfort or fullness
-
weight loss, intermittent fever
-
Hypoglycemia or hypocalcemia due to hormones
-
DIC or hemorrhagic shock due to rupture of tumor
-
Gross : Bulky tumors measuring 3 to 40 cms
-
Cut section: Coarsely lobulated appearance with soft bulging nodules ranging from yellow-orange to tan. Areas of hemorrhage, necrosis and cystic change can be present
-
Microscopy:
-
Architectural patterns –
-
Trabecular pattern with anastomosing columns separated by delicate fibrovascualar septa with sinusoids
-
Nesting or alveolar pattern
-
Solid or diffuse pattern
-
Mixture of these patterns
-
Tumor cells
-
Usually have acidophilic cytoplasm which is lipid depleted
-
Oncocytic cells with abundant granular eosinophilic cytoplasm
-
Occasional Lipofuscin pigment may be seen in cytoplasm
-
Few cells may show lipid droplets
-
Intracytoplasmic hyaline globules may be present
-
Nuclear pleomorphism may be present. Hyperchromatic nuclei, multilobated nuclei, nuclei with prominent nucleoli and nuclear pseudoinclusions may be present
-
Stromal changes
-
Myxoid stroma
-
Foci of calcifications
-
Metaplastic bone formation
-
Lipomatous or myelolipomatous change
-
Grades
-
Low grade – 20 or less /50 high power field
-
High grade – More than 20/ 50 high power field
-
Immunohistochemistry
-
Cytokeratin – negative (rarely positive)
-
Vimentin – positive
-
Melan A, Inhibin, Calretinin – Positive
-
Metastasis
-
Both lymphatic and hematogenous
-
common sites of metastasis are liver, lung, retroperitonium, lymphnodes and bones
-
Inferior vena cavae invasion producing obstruction producing edema of lower limbs and ascites
Prognosis
-
Features associated with recurrence and metastasis are
-
Mitotic rate of 6 or more/ 50 high power feild
-
Atypical mitosis
-
Invasion of vascular structures
