| Popis: | Melanoma metastases to the pituitary gland are extremely rare, with only a few reported cases. We report an unusual case of pituitary metastatic melanoma in which the patient presented with pituitary apoplexy. A 68-year-old man presented general fatigue and anorexia following sudden headache. Neurological examination disclosed bitemporal hemianopsia. Computed tomography (CT) scans revealed a suprasellar mass including intratumoral hematoma. Magnetic resonance (MR) images demonstrated a circumscribed mass lesion in the intra- and suprasellar regions, compressing the optic chiasm. Surgical exploration was performed through a transsphenoidal approach, and a mixture of tumor and necrotic tissue with old hematoma was obtained. The histological examination of the specimen revealed a partly necrotic, malignant tumor with focal melanotic pigmentation. Histopathologically, the diagnosis was consistent with pituitary apoplexy caused by hemorrhage from pituitary metastatic melanoma. |
