Aggressive Pituitary Tumours and Pituitary Carcinomas
Nature Reviews Endocrinology, 2021Although usually benign, anterior pituitary tumours occasionally exhibit aggressive behaviour, with invasion of surrounding tissues, rapid growth, resistance to conventional treatments and multiple recurrences. In very rare cases, they metastasize and are termed pituitary carcinomas.

Surgical management of pituitary adenomas continues to be a safe and effective method for treating many patients with these lesions. The goal of overall management should be to provide the patient with the most effective means of long-term control of this benign but potentially disabling disease. Currently, surgery has a significant role.

Pituitary enlargement mimicking pituitary tumor
Journal of Neurosurgery, 1985✓ Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions on computerized tomography (CT) scans. The presenting symptoms may be due to pituitary gland enlargement, as in two of the three cases reported here.

Pituitary siderosis: the dark side of the pituitary
The Lancet Diabetes & Endocrinology, 2016A 23-year-old woman with persistent secondary amenorrhoea, 2 years after completion of non-ovarian toxic chemotherapy for osteosarcoma, was referred from the oncologist for investigation. She had severe sicklecell disease, diagnosed at age 18 months, requiring frequent red blood cells, exchange transfusion treatments, and a splenectomy.

Pituitary function after pituitary apoplexy
The American Journal of Medicine, 1978Pituitary function was studied in nine patients who had recovered from pituitary apoplexy. All the patients recovered spontaneously; none required immediate surgery. Four of the patients had acromegaly, two had pituitary-dependent Cushing's syndrome, and a "functionless" pituitary adenoma was found in three. Low serum growth hormone concentrations were

Pituitary carcinoma is a extremely rare and is characterized by a very poor prognosis. Even if at diagnosis the presence of metastases is required to define a pituitary carcinoma, the lesion was almost invariably diagnosed first as a benign pituitary tumor, that after a variable period of latency, ranging from few months to many years, changed its ...

Pituitary hyperplasia mimicking pituitary tumor
Surgical Neurology, 1994Reactive enlargement of the pituitary gland in primary end organ failure may be indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. The diagnosis of pituitary hyperplasia secondary to end organ failure must be based on endocrinologic investigations.

Incidental pituitary masses are commonly found during CT and MR imaging performed for a variety of reasons. Screening for hormone oversecretion by these tumors seems to be warranted. Patients with lesions greater than 1 cm should be screened for hypopituitarism.

Aggressive Pituitary Tumors or Localized Pituitary Carcinomas: Defining Pituitary Tumors
Expert Review of Endocrinology & Metabolism, 2016Pituitary tumors are common and exhibit a wide spectrum of hormonal, proliferative and invasive behaviors. Traditional classifications consider them malignant only when they exhibit metastasis. Patients who suffer morbidity and mortality from aggressive tumors classified as "adenomas" are denied support provided to patients with "cancers" and in many ...
