Introduction: Anterior pituitary cells are characterised by functional lineages based on the expression pattern of transcription factors. Functional differentiation in the form of pituitary adenomas co-secreting ACTH and growth hormone is very rare. We report a case of multiple cell line pituitary adenoma resulting in acromegaly and ACTH dependent Cushing’s.Case: A 52-year-old woman of Ghanian origin (BMI of 57.5 kg/m2) presented with pro...

Silent corticoptroph adenomas (SCA) are pituitary tumours positive on immunohistochemical staining for ACTH but without clinical evidence of hypercortisolism. They account for 1.1–6% of surgically removed pituitary adenomas. Most tumours are macroadenomas with suprasellar extension present in 87–100% of the cases. They present with mass effects and this is in contrast to Cushing’s disease, which is mostly attributed to microadenomas. Reports suggest that these t...
