Type D Adipsia with Severe Hypernatremia: A Unique Presentation of an Extensive Intracranial Germinoma.

Intracranial germ cell tumors are uncommon brain tumors; germinoma is the most common tumor in children and young adults, and the most common regions affected are pineal gland and suprasellar region. Germinomas of the suprasellar region are accompanied by endocrine alterations, with adipsia being a rare presentation. Here, we present the case of a patient with an extensive intracranial germinoma whose initial presentation was adipsia, without any other endocrinological alteration, with development of severe hypernatremia and unusual manifestations derived from it, such as deep vein thrombosis, myopathy with rhabdomyolysis, and neurological axonal damage.

Autoimmune/inflammatory syndrome induced by methylmethacrylate associated to seronegative antiphospholipid syndrome and diffuse large B-cell non-Hodgkin's lymphoma.

Background: Autoimmune/inflammatory syndrome induced by adjuvants has been associated with different substances used for cosmetic purposes; for example, silicone, methylmethacrylate, autoimmune disorders and cancer.

Discussion: A 40-year-old man with a prior history of methylmethacrylate injection in the buttocks for aesthetic purposes 8 years ago, presented with deep venous thrombosis in the left leg 6 months ago, accompanied with inflammation, hardening, changes in colour, ulceration in the buttocks, arthritis, myalgias and fever.
