Cardiogenic shock in phaeochromocytoma multisystem crisis: a case report.

Background: Phaeochromocytoma multisystem crisis (PMC) is characterized by labile blood pressures (extremes of hypo- and/or hypertension) and multiorgan failure as a result of catecholamine excess. Initial stabilization requires pharmacological and/or mechanical circulatory support, followed by the institution of antihypertensives to correct the underlying pathophysiology.

Case Summary: A previously well 40-year-old male developed a sudden onset of breathlessness.

Pulmonary Mucoepidermoid Carcinoma With Multiple Paraneoplastic Syndromes.

Pulmonary mucoepidermoid carcinoma (PMEC) is rare and challenging to diagnose. Its association with paraneoplastic syndromes is poorly described. It is also uncommon for a patient with lung cancer to present with multiple paraneoplastic syndromes.

Pigmented epithelioid melanocytoma with nodal melanosis: A rare cause of cystic cervical lymphadenopathy.

Background: Head and neck malignancies often present as firm, solid nodal masses. However, malignancies arising from Waldeyer's Ring may give rise to cystic lymph nodes.

Methods: A 57-year-old man was referred for left-sided neck swelling of 2 weeks' duration.

Persistent hyperthyroidism and Graves' ophthalmopathy after total thyroidectomy.

Unlabelled: We report a patient with Graves' disease who remained persistently hyperthyroid after a total thyroidectomy and also developed Graves' ophthalmopathy 5 months after surgery. She was subsequently found to have a mature cystic teratoma containing struma ovarii after undergoing a total hysterectomy and salpingo-oophorectomy for an incidental ovarian lesion.

Learning Points: It is important to investigate for other causes of primary hyperthyroidism when thyrotoxicosis persists after total thyroidectomy.
